salt.states.file¶

Operations on regular files, special files, directories, and symlinks¶

Salt States can aggressively manipulate files on a system. There are a number of ways in which files can be managed.

Regular files can be enforced with the file.managed state. This state downloads files from the salt master and places them on the target system. Managed files can be rendered as a jinja, mako, or wempy template, adding a dynamic component to file management. An example of file.managed which makes use of the jinja templating system would look like this:

/etc/http/conf/http.conf:
  file.managed:
    - source: salt://apache/http.conf
    - user: root
    - group: root
    - mode: 644
    - attrs: ai
    - template: jinja
    - defaults:
        custom_var: "default value"
        other_var: 123
{% if grains['os'] == 'Ubuntu' %}
    - context:
        custom_var: "override"
{% endif %}

It is also possible to use the py renderer as a templating option. The template would be a Python script which would need to contain a function called run(), which returns a string. All arguments to the state will be made available to the Python script as globals. The returned string will be the contents of the managed file. For example:

def run():
    lines = ['foo', 'bar', 'baz']
    lines.extend([source, name, user, context])  # Arguments as globals
    return '\n\n'.join(lines)

Note

The defaults and context arguments require extra indentation (four spaces instead of the normal two) in order to create a nested dictionary. More information.

If using a template, any user-defined template variables in the file defined in source must be passed in using the defaults and/or context arguments. The general best practice is to place default values in defaults, with conditional overrides going into context, as seen above.

The template will receive a variable custom_var, which would be accessed in the template using {{ custom_var }}. If the operating system is Ubuntu, the value of the variable custom_var would be override, otherwise it is the default default value

The source parameter can be specified as a list. If this is done, then the first file to be matched will be the one that is used. This allows you to have a default file on which to fall back if the desired file does not exist on the salt fileserver. Here's an example:

/etc/foo.conf:
  file.managed:
    - source:
      - salt://foo.conf.{{ grains['fqdn'] }}
      - salt://foo.conf.fallback
    - user: foo
    - group: users
    - mode: 644
    - attrs: i
    - backup: minion

Note

Salt supports backing up managed files via the backup option. For more details on this functionality please review the backup_mode documentation.

The source parameter can also specify a file in another Salt environment. In this example foo.conf in the dev environment will be used instead.

/etc/foo.conf:
  file.managed:
    - source:
      - 'salt://foo.conf?saltenv=dev'
    - user: foo
    - group: users
    - mode: '0644'
    - attrs: i

Warning

When using a mode that includes a leading zero you must wrap the value in single quotes. If the value is not wrapped in quotes it will be read by YAML as an integer and evaluated as an octal.

The names parameter, which is part of the state compiler, can be used to expand the contents of a single state declaration into multiple, single state declarations. Each item in the names list receives its own individual state name and is converted into its own low-data structure. This is a convenient way to manage several files with similar attributes.

salt_master_conf:
  file.managed:
    - user: root
    - group: root
    - mode: '0644'
    - names:
      - /etc/salt/master.d/master.conf:
        - source: salt://saltmaster/master.conf
      - /etc/salt/minion.d/minion-99.conf:
        - source: salt://saltmaster/minion.conf

Note

There is more documentation about this feature in the Names declaration section of the Highstate docs.

Special files can be managed via the mknod function. This function will create and enforce the permissions on a special file. The function supports the creation of character devices, block devices, and FIFO pipes. The function will create the directory structure up to the special file if it is needed on the minion. The function will not overwrite or operate on (change major/minor numbers) existing special files with the exception of user, group, and permissions. In most cases the creation of some special files require root permissions on the minion. This would require that the minion to be run as the root user. Here is an example of a character device:

/var/named/chroot/dev/random:
  file.mknod:
    - ntype: c
    - major: 1
    - minor: 8
    - user: named
    - group: named
    - mode: 660

Here is an example of a block device:

/var/named/chroot/dev/loop0:
  file.mknod:
    - ntype: b
    - major: 7
    - minor: 0
    - user: named
    - group: named
    - mode: 660

Here is an example of a fifo pipe:

/var/named/chroot/var/log/logfifo:
  file.mknod:
    - ntype: p
    - user: named
    - group: named
    - mode: 660

Directories can be managed via the directory function. This function can create and enforce the permissions on a directory. A directory statement will look like this:

/srv/stuff/substuf:
  file.directory:
    - user: fred
    - group: users
    - mode: 755
    - makedirs: True

If you need to enforce user and/or group ownership or permissions recursively on the directory's contents, you can do so by adding a recurse directive:

/srv/stuff/substuf:
  file.directory:
    - user: fred
    - group: users
    - mode: 755
    - makedirs: True
    - recurse:
      - user
      - group
      - mode

As a default, mode will resolve to dir_mode and file_mode, to specify both directory and file permissions, use this form:

/srv/stuff/substuf:
  file.directory:
    - user: fred
    - group: users
    - file_mode: 744
    - dir_mode: 755
    - makedirs: True
    - recurse:
      - user
      - group
      - mode

Symlinks can be easily created; the symlink function is very simple and only takes a few arguments:

/etc/grub.conf:
  file.symlink:
    - target: /boot/grub/grub.conf

Recursive directory management can also be set via the recurse function. Recursive directory management allows for a directory on the salt master to be recursively copied down to the minion. This is a great tool for deploying large code and configuration systems. A state using recurse would look something like this:

/opt/code/flask:
  file.recurse:
    - source: salt://code/flask
    - include_empty: True

A more complex recurse example:

{% set site_user = 'testuser' %}
{% set site_name = 'test_site' %}
{% set project_name = 'test_proj' %}
{% set sites_dir = 'test_dir' %}

django-project:
  file.recurse:
    - name: {{ sites_dir }}/{{ site_name }}/{{ project_name }}
    - user: {{ site_user }}
    - dir_mode: 2775
    - file_mode: '0644'
    - template: jinja
    - source: salt://project/templates_dir
    - include_empty: True

Retention scheduling can be applied to manage contents of backup directories. For example:

/var/backups/example_directory:
  file.retention_schedule:
    - strptime_format: example_name_%Y%m%dT%H%M%S.tar.bz2
    - retain:
        most_recent: 5
        first_of_hour: 4
        first_of_day: 14
        first_of_week: 6
        first_of_month: 6
        first_of_year: all

salt.states.file.absent(name, **kwargs)¶

Make sure that the named file or directory is absent. If it exists, it will be deleted. This will work to reverse any of the functions in the file state module. If a directory is supplied, it will be recursively deleted.

If only the contents of the directory need to be deleted but not the directory itself, use file.directory with clean=True

name: The path which should be deleted

salt.states.file.accumulated(name, filename, text, **kwargs)¶

Prepare accumulator which can be used in template in file.managed state. Accumulator dictionary becomes available in template. It can also be used in file.blockreplace.

name: Accumulator name
filename: Filename which would receive this accumulator (see file.managed state documentation about name)
text: String or list for adding in accumulator
require_in / watch_in: One of them required for sure we fill up accumulator before we manage the file. Probably the same as filename

Example:

Given the following:

animals_doing_things:
  file.accumulated:
    - filename: /tmp/animal_file.txt
    - text: ' jumps over the lazy dog.'
    - require_in:
      - file: animal_file

animal_file:
  file.managed:
    - name: /tmp/animal_file.txt
    - source: salt://animal_file.txt
    - template: jinja

One might write a template for animal_file.txt like the following:

The quick brown fox{% for animal in accumulator['animals_doing_things'] %}{{ animal }}{% endfor %}

Collectively, the above states and template file will produce:

The quick brown fox jumps over the lazy dog.

Multiple accumulators can be "chained" together.

Note

The 'accumulator' data structure is a Python dictionary. Do not expect any loop over the keys in a deterministic order!

salt.states.file.append(name, text=None, makedirs=False, source=None, source_hash=None, template='jinja', sources=None, source_hashes=None, defaults=None, context=None, ignore_whitespace=True)¶

Ensure that some text appears at the end of a file.

The text will not be appended if it already exists in the file. A single string of text or a list of strings may be appended.

name

The location of the file to append to.

text

The text to be appended, which can be a single string or a list of strings.

makedirs

If the file is located in a path without a parent directory, then the state will fail. If makedirs is set to True, then the parent directories will be created to facilitate the creation of the named file. Defaults to False.

source

A single source file to append. This source file can be hosted on either the salt master server, or on an HTTP or FTP server. Both HTTPS and HTTP are supported as well as downloading directly from Amazon S3 compatible URLs with both pre-configured and automatic IAM credentials (see s3.get state documentation). File retrieval from Openstack Swift object storage is supported via swift://container/object_path URLs (see swift.get documentation).

For files hosted on the salt file server, if the file is located on the master in the directory named spam, and is called eggs, the source string is salt://spam/eggs.

If the file is hosted on an HTTP or FTP server, the source_hash argument is also required.

source_hash

This can be one of the following:

a source hash string
the URI of a file that contains source hash strings

The function accepts the first encountered long unbroken alphanumeric string of correct length as a valid hash, in order from most secure to least secure:

Type    Length
======  ======
sha512     128
sha384      96
sha256      64
sha224      56
sha1        40
md5         32

See the source_hash parameter description for file.managed function for more details and examples.

template

The named templating engine will be used to render the appended-to file. Defaults to jinja. The following templates are supported:

cheetah
genshi
jinja
mako
py
wempy

sources

A list of source files to append. If the files are hosted on an HTTP or FTP server, the source_hashes argument is also required.

source_hashes

A list of source_hashes corresponding to the sources list specified in the sources argument.

defaults

Default context passed to the template.

context

Overrides default context variables passed to the template.

ignore_whitespace

New in version 2015.8.4.

Spaces and Tabs in text are ignored by default, when searching for the appending content, one space or multiple tabs are the same for salt. Set this option to False if you want to change this behavior.

Multi-line example:

/etc/motd:
  file.append:
    - text: |
        Thou hadst better eat salt with the Philosophers of Greece,
        than sugar with the Courtiers of Italy.
        - Benjamin Franklin

Multiple lines of text:

/etc/motd:
  file.append:
    - text:
      - Trust no one unless you have eaten much salt with him.
      - "Salt is born of the purest of parents: the sun and the sea."

Gather text from multiple template files:

/etc/motd:
  file:
    - append
    - template: jinja
    - sources:
      - salt://motd/devops-messages.tmpl
      - salt://motd/hr-messages.tmpl
      - salt://motd/general-messages.tmpl

New in version 0.9.5.

salt.states.file.blockreplace(name, marker_start='#-- start managed zone --', marker_end='#-- end managed zone --', source=None, source_hash=None, template='jinja', sources=None, source_hashes=None, defaults=None, context=None, content='', append_if_not_found=False, prepend_if_not_found=False, backup='.bak', show_changes=True, append_newline=None, insert_before_match=None, insert_after_match=None)¶

Maintain an edit in a file in a zone delimited by two line markers

New in version 2014.1.0.

Changed in version 2017.7.5,2018.3.1: append_newline argument added. Additionally, to improve idempotence, if the string represented by marker_end is found in the middle of the line, the content preceding the marker will be removed when the block is replaced. This allows one to remove append_newline: False from the SLS and have the block properly replaced if the end of the content block is immediately followed by the marker_end (i.e. no newline before the marker).

A block of content delimited by comments can help you manage several lines entries without worrying about old entries removal. This can help you maintaining an un-managed file containing manual edits.

Note

This function will store two copies of the file in-memory (the original version and the edited version) in order to detect changes and only edit the targeted file if necessary.

Additionally, you can use file.accumulated and target this state. All accumulated data dictionaries' content will be added in the content block.

name

Filesystem path to the file to be edited

marker_start

The line content identifying a line as the start of the content block. Note that the whole line containing this marker will be considered, so whitespace or extra content before or after the marker is included in final output

marker_end

The line content identifying the end of the content block. As of versions 2017.7.5 and 2018.3.1, everything up to the text matching the marker will be replaced, so it's important to ensure that your marker includes the beginning of the text you wish to replace.

content

The content to be used between the two lines identified by marker_start and marker_end

source

The source file to download to the minion, this source file can be hosted on either the salt master server, or on an HTTP or FTP server. Both HTTPS and HTTP are supported as well as downloading directly from Amazon S3 compatible URLs with both pre-configured and automatic IAM credentials. (see s3.get state documentation) File retrieval from Openstack Swift object storage is supported via swift://container/object_path URLs, see swift.get documentation. For files hosted on the salt file server, if the file is located on the master in the directory named spam, and is called eggs, the source string is salt://spam/eggs. If source is left blank or None (use ~ in YAML), the file will be created as an empty file and the content will not be managed. This is also the case when a file already exists and the source is undefined; the contents of the file will not be changed or managed.

If the file is hosted on a HTTP or FTP server then the source_hash argument is also required.

file_override_example:
  file.blockreplace:
    - name: /etc/example.conf
    - source:
      - salt://file_that_does_not_exist
      - salt://file_that_exists

source_hash

This can be one of the following:

a source hash string
the URI of a file that contains source hash strings

The function accepts the first encountered long unbroken alphanumeric string of correct length as a valid hash, in order from most secure to least secure:

Type    Length
======  ======
sha512     128
sha384      96
sha256      64
sha224      56
sha1        40
md5         32

See the source_hash parameter description for file.managed function for more details and examples.

template

Templating engine to be used to render the downloaded file. The following engines are supported:

cheetah
genshi
jinja
mako
py
wempy

context

Overrides default context variables passed to the template

defaults

Default context passed to the template

append_if_not_found

If markers are not found and this option is set to True, the content block will be appended to the file.

prepend_if_not_found

If markers are not found and this option is set to True, the content block will be prepended to the file.

insert_before_match

If markers are not found, this parameter can be set to a regex which will insert the block before the first found occurrence in the file.

New in version 3001.

insert_after_match

If markers are not found, this parameter can be set to a regex which will insert the block after the first found occurrence in the file.

New in version 3001.

backup

The file extension to use for a backup of the file if any edit is made. Set this to False to skip making a backup.

show_changes

Controls how changes are presented. If True, the Changes section of the state return will contain a unified diff of the changes made. If False, then it will contain a boolean (True if any changes were made, otherwise False).

append_newline

Controls whether or not a newline is appended to the content block. If the value of this argument is True then a newline will be added to the content block. If it is False, then a newline will not be added to the content block. If it is unspecified, then a newline will only be added to the content block if it does not already end in a newline.

New in version 2017.7.5,2018.3.1.

Example of usage with an accumulator and with a variable:

{% set myvar = 42 %}
hosts-config-block-{{ myvar }}:
  file.blockreplace:
    - name: /etc/hosts
    - marker_start: "# START managed zone {{ myvar }} -DO-NOT-EDIT-"
    - marker_end: "# END managed zone {{ myvar }} --"
    - content: 'First line of content'
    - append_if_not_found: True
    - backup: '.bak'
    - show_changes: True

hosts-config-block-{{ myvar }}-accumulated1:
  file.accumulated:
    - filename: /etc/hosts
    - name: my-accumulator-{{ myvar }}
    - text: "text 2"
    - require_in:
      - file: hosts-config-block-{{ myvar }}

hosts-config-block-{{ myvar }}-accumulated2:
  file.accumulated:
    - filename: /etc/hosts
    - name: my-accumulator-{{ myvar }}
    - text: |
         text 3
         text 4
    - require_in:
      - file: hosts-config-block-{{ myvar }}

will generate and maintain a block of content in /etc/hosts:

# START managed zone 42 -DO-NOT-EDIT-
First line of content
text 2
text 3
text 4
# END managed zone 42 --

salt.states.file.cached(name, source_hash='', source_hash_name=None, skip_verify=False, saltenv='base', use_etag=False, source_hash_sig=None, signed_by_any=None, signed_by_all=None, keyring=None, gnupghome=None, sig_backend='gpg')¶

New in version 2017.7.3.

Changed in version 3005.

Ensures that a file is saved to the minion's cache. This state is primarily invoked by other states to ensure that we do not re-download a source file if we do not need to.

name: The URL of the file to be cached. To cache a file from an environment other than base, either use the saltenv argument or include the saltenv in the URL (e.g. salt://path/to/file.conf?saltenv=dev).

Note

A list of URLs is not supported, this must be a single URL. If a local file is passed here, then the state will obviously not try to download anything, but it will compare a hash if one is specified.
source_hash: See the documentation for this same argument in the file.managed state.

Note

For remote files not originating from the salt:// fileserver, such as http(s) or ftp servers, this state will not re-download the file if the locally-cached copy matches this hash. This is done to prevent unnecessary downloading on repeated runs of this state. To update the cached copy of a file, it is necessary to update this hash.
source_hash_name: See the documentation for this same argument in the file.managed state.
skip_verify: See the documentation for this same argument in the file.managed state.

Note

Setting this to True will result in a copy of the file being downloaded from a remote (http(s), ftp, etc.) source each time the state is run.
saltenv: Used to specify the environment from which to download a file from the Salt fileserver (i.e. those with salt:// URL).
use_etag: If True, remote http/https file sources will attempt to use the ETag header to determine if the remote file needs to be downloaded. This provides a lightweight mechanism for promptly refreshing files changed on a web server without requiring a full hash comparison via the source_hash parameter.

New in version 3005.
source_hash_sig: When name is a remote file source, source_hash is a file, skip_verify is not true and use_etag is not true, ensure a valid signature exists on the source hash file. Set this to true for an inline (clearsigned) signature, or to a file URI retrievable by :py:func:`cp.cache_file <salt.modules.cp.cache_file> for a detached one.

Note

A signature on the source_hash file is enforced regardless of changes since its contents are used to check if an existing file is in the correct state - but only for remote sources!

New in version 3007.0.
signed_by_any: When verifying source_hash_sig, require at least one valid signature from one of a list of keys. By default, this is passed to gpg.verify, meaning a key is identified by its fingerprint.

New in version 3007.0.
signed_by_all: When verifying source_hash_sig, require a valid signature from each of the keys in this list. By default, this is passed to gpg.verify, meaning a key is identified by its fingerprint.

New in version 3007.0.
keyring: When verifying signatures, use this keyring.

New in version 3007.0.
gnupghome: When verifying signatures, use this GnuPG home.

New in version 3007.0.
sig_backend: When verifying signatures, use this execution module as a backend. It must be compatible with the gpg.verify API. Defaults to gpg. All signature-related parameters are passed through.

New in version 3008.0.

This state will in most cases not be useful in SLS files, but it is useful when writing a state or remote-execution module that needs to make sure that a file at a given URL has been downloaded to the cachedir. One example of this is in the archive.extracted state:

result = __states__['file.cached'](source_match,
                                   source_hash=source_hash,
                                   source_hash_name=source_hash_name,
                                   skip_verify=skip_verify,
                                   saltenv=__env__)

This will return a dictionary containing the state's return data, including a result key which will state whether or not the state was successful. Note that this will not catch exceptions, so it is best used within a try/except.

Once this state has been run from within another state or remote-execution module, the actual location of the cached file can be obtained using cp.is_cached:

cached = __salt__['cp.is_cached'](source_match, saltenv=__env__)

This function will return the cached path of the file, or an empty string if the file is not present in the minion cache.

salt.states.file.comment(name, regex, char='#', backup='.bak', ignore_missing=False)¶

New in version 0.9.5.

Changed in version 3005.

Comment out specified lines in a file.

name

The full path to the file to be edited

regex

A regular expression used to find the lines that are to be commented; this pattern will be wrapped in parenthesis and will move any preceding/trailing ^ or $ characters outside the parenthesis (e.g., the pattern ^foo$ will be rewritten as ^(foo)$) Note that you _need_ the leading ^, otherwise each time you run highstate, another comment char will be inserted.

char

The character to be inserted at the beginning of a line in order to comment it out

backup

The file will be backed up before edit with this file extension

Warning

This backup will be overwritten each time sed / comment / uncomment is called. Meaning the backup will only be useful after the first invocation.

Set to False/None to not keep a backup.

ignore_missing

Ignore a failure to find the regex in the file. This is useful for scenarios where a line must only be commented if it is found in the file.

New in version 3005.

Usage:

/etc/fstab:
  file.comment:
    - regex: ^bind 127.0.0.1

salt.states.file.copy_(name, source, force=False, makedirs=False, preserve=False, user=None, group=None, mode=None, dir_mode=None, subdir=False, **kwargs)¶

If the file defined by the source option exists on the minion, copy it to the named path. The file will not be overwritten if it already exists, unless the force option is set to True.

Note

This state only copies files from one location on a minion to another location on the same minion. For copying files from the master, use a file.managed state.

name

The location of the file to copy to

source

The location of the file to copy to the location specified with name

force

If the target location is present then the file will not be moved, specify "force: True" to overwrite the target file

makedirs

If the target subdirectories don't exist create them

preserve

New in version 2015.5.0.

Set preserve: True to preserve user/group ownership and mode after copying. Default is False. If preserve is set to True, then user/group/mode attributes will be ignored.

user

New in version 2015.5.0.

The user to own the copied file, this defaults to the user salt is running as on the minion. If preserve is set to True, then this will be ignored

group

New in version 2015.5.0.

The group to own the copied file, this defaults to the group salt is running as on the minion. If preserve is set to True or on Windows this will be ignored

mode

New in version 2015.5.0.

The permissions to set on the copied file, aka 644, '0775', '4664'. If preserve is set to True, then this will be ignored. Not supported on Windows.

The default mode for new files and directories corresponds umask of salt process. For existing files and directories it's not enforced.

dir_mode

New in version 3006.0.

If directories are to be created, passing this option specifies the permissions for those directories. If this is not set, directories will be assigned permissions by adding the execute bit to the mode of the files.

The default mode for new files and directories corresponds to the umask of the salt process. Not enforced for existing files and directories.

subdir

New in version 2015.5.0.

If the name is a directory then place the file inside the named directory

Note

The copy function accepts paths that are local to the Salt minion. This function does not support salt://, http://, or the other additional file paths that are supported by states.file.managed and states.file.recurse.

Usage:

# Use 'copy', not 'copy_'
/etc/example.conf:

salt.states.file.decode(name, encoded_data=None, contents_pillar=None, encoding_type='base64', checksum='md5')¶

Decode an encoded file and write it to disk

New in version 2016.3.0.

name: Path of the file to be written.
encoded_data: The encoded file. Either this option or contents_pillar must be specified.
contents_pillar: A Pillar path to the encoded file. Uses the same path syntax as pillar.get. The hashutil.base64_encodefile function can load encoded content into Pillar. Either this option or encoded_data must be specified.
encoding_type: The type of encoding.
checksum: The hashing algorithm to use to generate checksums. Wraps the hashutil.digest execution function.

Usage:

write_base64_encoded_string_to_a_file:
  file.decode:
    - name: /tmp/new_file
    - encoding_type: base64
    - contents_pillar: mypillar:thefile

# or

write_base64_encoded_string_to_a_file:
  file.decode:
    - name: /tmp/new_file
    - encoding_type: base64
    - encoded_data: |
        Z2V0IHNhbHRlZAo=

Be careful with multi-line strings that the YAML indentation is correct. E.g.,

write_base64_encoded_string_to_a_file:
  file.decode:
    - name: /tmp/new_file
    - encoding_type: base64
    - encoded_data: |
        {{ salt.pillar.get('path:to:data') | indent(8) }}

salt.states.file.directory(name, user=None, group=None, recurse=None, max_depth=None, dir_mode=None, file_mode=None, makedirs=False, clean=False, require=None, exclude_pat=None, follow_symlinks=False, force=False, backupname=None, allow_symlink=True, children_only=False, win_owner=None, win_perms=None, win_deny_perms=None, win_inheritance=True, win_perms_reset=False, **kwargs)¶

Ensure that a named directory is present and has the right perms

name

The location to create or manage a directory, as an absolute path

user

The user to own the directory; this defaults to the user salt is running as on the minion

group

The group ownership set for the directory; this defaults to the group salt is running as on the minion. On Windows, this is ignored

recurse

Enforce user/group ownership and mode of directory recursively. Accepts a list of strings representing what you would like to recurse. If mode is defined, will recurse on both file_mode and dir_mode if they are defined. If ignore_files or ignore_dirs is included, files or directories will be left unchanged respectively. directories will be left unchanged respectively. If silent is defined, individual file/directory change notifications will be suppressed.

Example:

/var/log/httpd:
  file.directory:
    - user: root
    - group: root
    - dir_mode: 755
    - file_mode: 644
    - recurse:
      - user
      - group
      - mode

Leave files or directories unchanged:

/var/log/httpd:
  file.directory:
    - user: root
    - group: root
    - dir_mode: 755
    - file_mode: 644
    - recurse:
      - user
      - group
      - mode
      - ignore_dirs

New in version 2015.5.0.

max_depth

Limit the recursion depth. The default is no limit=None. 'max_depth' and 'clean' are mutually exclusive.

New in version 2016.11.0.

dir_mode / mode

The permissions mode to set any directories created. Not supported on Windows.

The default mode for new files and directories corresponds umask of salt process. For existing files and directories it's not enforced.

file_mode

The permissions mode to set any files created if 'mode' is run in 'recurse'. This defaults to dir_mode. Not supported on Windows.

The default mode for new files and directories corresponds umask of salt process. For existing files and directories it's not enforced.

makedirs

If the directory is located in a path without a parent directory, then the state will fail. If makedirs is set to True, then the parent directories will be created to facilitate the creation of the named file.

clean

Remove any files that are not referenced by a required file state. See examples below for more info. If this option is set then everything in this directory will be deleted unless it is required. 'clean' and 'max_depth' are mutually exclusive.

require

Require other resources such as packages or files.

exclude_pat

When 'clean' is set to True, exclude this pattern from removal list and preserve in the destination.

follow_symlinks

If the desired path is a symlink (or recurse is defined and a symlink is encountered while recursing), follow it and check the permissions of the directory/file to which the symlink points.

New in version 2014.1.4.

Changed in version 3001.1: If set to False symlinks permissions are ignored on Linux systems because it does not support permissions modification. Symlinks permissions are always 0o777 on Linux.

force

If the name of the directory exists and is not a directory and force is set to False, the state will fail. If force is set to True, the file in the way of the directory will be deleted to make room for the directory, unless backupname is set, then it will be renamed.

New in version 2014.7.0.

backupname

If the name of the directory exists and is not a directory, it will be renamed to the backupname. If the backupname already exists and force is False, the state will fail. Otherwise, the backupname will be removed first.

New in version 2014.7.0.

allow_symlink

If allow_symlink is True and the specified path is a symlink, it will be allowed to remain if it points to a directory. If allow_symlink is False then the state will fail, unless force is also set to True, in which case it will be removed or renamed, depending on the value of the backupname argument.

New in version 2014.7.0.

children_only

If children_only is True the base of a path is excluded when performing a recursive operation. In case of /path/to/base, base will be ignored while all of /path/to/base/* are still operated on.

win_owner

The owner of the directory. If this is not passed, user will be used. If user is not passed, the account under which Salt is running will be used.

New in version 2017.7.0.

win_perms

A dictionary containing permissions to grant and their propagation. For example: {'Administrators': {'perms': 'full_control', 'applies_to': 'this_folder_only'}} Can be a single basic perm or a list of advanced perms. perms must be specified. applies_to is optional and defaults to this_folder_subfolder_files.

New in version 2017.7.0.

win_deny_perms

A dictionary containing permissions to deny and their propagation. For example: {'Administrators': {'perms': 'full_control', 'applies_to': 'this_folder_only'}} Can be a single basic perm or a list of advanced perms.

New in version 2017.7.0.

win_inheritance

True to inherit permissions from the parent directory, False not to inherit permission.

New in version 2017.7.0.

win_perms_reset

If True the existing DACL will be cleared and replaced with the settings defined in this function. If False, new entries will be appended to the existing DACL. Default is False.

New in version 2018.3.0.

Here's an example using the above win_* parameters:

create_config_dir:
  file.directory:
    - name: 'C:\config\'
    - win_owner: Administrators
    - win_perms:
        # Basic Permissions
        dev_ops:
          perms: full_control
        # List of advanced permissions
        appuser:
          perms:
            - read_attributes
            - read_ea
            - create_folders
            - read_permissions
          applies_to: this_folder_only
        joe_snuffy:
          perms: read
          applies_to: this_folder_files
    - win_deny_perms:
        fred_snuffy:
          perms: full_control
    - win_inheritance: False

For clean: True there is no mechanism that allows all states and modules to enumerate the files that they manage, so for file.directory to know what files are managed by Salt, a file state targeting managed files is required. To use a contrived example, the following states will always have changes, despite the file named okay being created by a Salt state:

silly_way_of_creating_a_file:
  cmd.run:
     - name: mkdir -p /tmp/dont/do/this && echo "seriously" > /tmp/dont/do/this/okay
     - unless: grep seriously /tmp/dont/do/this/okay

will_always_clean:
  file.directory:
    - name: /tmp/dont/do/this
    - clean: True

Because cmd.run has no way of communicating that it's creating a file, will_always_clean will remove the newly created file. Of course, every time the states run the same thing will happen - the silly_way_of_creating_a_file will crete the file and will_always_clean will always remove it. Over and over again, no matter how many times you run it.

To make this example work correctly, we need to add a file state that targets the file, and a require between the file states.

silly_way_of_creating_a_file:
  cmd.run:
     - name: mkdir -p /tmp/dont/do/this && echo "seriously" > /tmp/dont/do/this/okay
     - unless: grep seriously /tmp/dont/do/this/okay
  file.managed:
     - name: /tmp/dont/do/this/okay
     - create: False
     - replace: False
     - require_in:
       - file: will_always_clean

Now there is a file state that clean can check, so running those states will work as expected. The file will be created with the specific contents, and clean will ignore the file because it is being managed by a salt file state. Note that if require_in was placed under cmd.run, it would not work, because the requisite is for the cmd, not the file.

silly_way_of_creating_a_file:
  cmd.run:
     - name: mkdir -p /tmp/dont/do/this && echo "seriously" > /tmp/dont/do/this/okay
     - unless: grep seriously /tmp/dont/do/this/okay
     # This part should be under file.managed
     - require_in:
       - file: will_always_clean
  file.managed:
     - name: /tmp/dont/do/this/okay
     - create: False
     - replace: False

Any other state that creates a file as a result, for example pkgrepo, must have the resulting files referenced in a file state in order for clean: True to ignore them. Also note that the requisite (require_in vs require) works in both directions:

clean_dir:
  file.directory:
    - name: /tmp/a/better/way
    - require:
      - file: a_better_way

a_better_way:
  file.managed:
    - name: /tmp/a/better/way/truely
    - makedirs: True
    - contents: a much better way

Works the same as this:

clean_dir:
  file.directory:
    - name: /tmp/a/better/way
    - clean: True

a_better_way:
  file.managed:
    - name: /tmp/a/better/way/truely
    - makedirs: True
    - contents: a much better way
    - require_in:
      - file: clean_dir

A common mistake here is to forget the state name and id are both required for requisites:

# Correct:
/path/to/some/file:
  file.managed:
    - contents: Cool
    - require_in:
      - file: clean_dir

# Incorrect
/path/to/some/file:
  file.managed:
    - contents: Cool
    - require_in:
      # should be `- file: clean_dir`
      - clean_dir

# Also incorrect
/path/to/some/file:
  file.managed:
    - contents: Cool
    - require_in:
      # should be `- file: clean_dir`
      - file

salt.states.file.exists(name, **kwargs)¶

Verify that the named file or directory is present or exists. Ensures pre-requisites outside of Salt's purview (e.g., keytabs, private keys, etc.) have been previously satisfied before deployment.

This function does not create the file if it doesn't exist, it will return an error.

name: Absolute path which must exist

salt.states.file.hardlink(name, target, force=False, makedirs=False, user=None, group=None, dir_mode=None, **kwargs)¶

Create a hard link If the file already exists and is a hard link pointing to any location other than the specified target, the hard link will be replaced. If the hard link is a regular file or directory then the state will return False. If the regular file is desired to be replaced with a hard link pass force: True

name: The location of the hard link to create
target: The location that the hard link points to
force: If the name of the hard link exists and force is set to False, the state will fail. If force is set to True, the file or directory in the way of the hard link file will be deleted to make room for the hard link, unless backupname is set, when it will be renamed
makedirs: If the location of the hard link does not already have a parent directory then the state will fail, setting makedirs to True will allow Salt to create the parent directory
user: The user to own any directories made if makedirs is set to true. This defaults to the user salt is running as on the minion
group: The group ownership set on any directories made if makedirs is set to true. This defaults to the group salt is running as on the minion. On Windows, this is ignored
dir_mode: If directories are to be created, passing this option specifies the permissions for those directories.

salt.states.file.keyvalue(name, key=None, value=None, key_values=None, separator='=', append_if_not_found=False, prepend_if_not_found=False, search_only=False, show_changes=True, ignore_if_missing=False, count=1, uncomment=None, key_ignore_case=False, value_ignore_case=False, create_if_missing=False)¶

Key/Value based editing of a file.

New in version 3001.

This function differs from file.replace in that it is able to search for keys, followed by a customizable separator, and replace the value with the given value. Should the value be the same as the one already in the file, no changes will be made.

Either supply both key and value parameters, or supply a dictionary with key / value pairs. It is an error to supply both.

name: Name of the file to search/replace in.
key: Key to search for when ensuring a value. Use in combination with a value parameter.
value: Value to set for a given key. Use in combination with a key parameter.
key_values: Dictionary of key / value pairs to search for and ensure values for. Used to specify multiple key / values at once.
separator: Separator which separates key from value.
append_if_not_found: Append the key/value to the end of the file if not found. Note that this takes precedence over prepend_if_not_found.
prepend_if_not_found: Prepend the key/value to the beginning of the file if not found. Note that append_if_not_found takes precedence.
show_changes: Show a diff of the resulting removals and inserts.
ignore_if_missing: Return with success even if the file is not found (or not readable).
count: Number of occurrences to allow (and correct), default is 1. Set to -1 to replace all, or set to 0 to remove all lines with this key regardsless of its value.

Note

Any additional occurrences after count are removed. A count of -1 will only replace all occurrences that are currently uncommented already. Lines commented out will be left alone.

uncomment: Disregard and remove supplied leading characters when finding keys. When set to None, lines that are commented out are left for what they are.

Note

The argument to uncomment is not a prefix string. Rather; it is a set of characters, each of which are stripped.

key_ignore_case: Keys are matched case insensitively. When a value is changed the matched key is kept as-is.
value_ignore_case: Values are checked case insensitively, trying to set e.g. 'Yes' while the current value is 'yes', will not result in changes when value_ignore_case is set to True.
create_if_missing: Create the file if the destination file is not found.

New in version 3007.0.

An example of using file.keyvalue to ensure sshd does not allow for root to login with a password and at the same time setting the login-gracetime to 1 minute and disabling all forwarding:

sshd_config_harden:
    file.keyvalue:
      - name: /etc/ssh/sshd_config
      - key_values:
          permitrootlogin: 'without-password'
          LoginGraceTime: '1m'
          DisableForwarding: 'yes'
      - separator: ' '
      - uncomment: '# '
      - key_ignore_case: True
      - append_if_not_found: True

The same example, except for only ensuring PermitRootLogin is set correctly. Thus being able to use the shorthand key and value parameters instead of key_values.

sshd_config_harden:
    file.keyvalue:
      - name: /etc/ssh/sshd_config
      - key: PermitRootLogin
      - value: without-password
      - separator: ' '
      - uncomment: '# '
      - key_ignore_case: True
      - append_if_not_found: True

Note

Notice how the key is not matched case-sensitively, this way it will correctly identify both 'PermitRootLogin' as well as 'permitrootlogin'.

salt.states.file.line(name, content=None, match=None, mode=None, location=None, before=None, after=None, show_changes=True, backup=False, quiet=False, indent=True, create=False, user=None, group=None, file_mode=None)¶

Line-focused editing of a file.

New in version 2015.8.0.

Note

file.line exists for historic reasons, and is not generally recommended. It has a lot of quirks. You may find file.replace to be more suitable.

file.line is most useful if you have single lines in a file, potentially a config file, that you would like to manage. It can remove, add, and replace lines.

name

Filesystem path to the file to be edited.

content

Content of the line. Allowed to be empty if mode=delete.

match

Match the target line for an action by a fragment of a string or regular expression.

If neither before nor after are provided, and match is also None, match falls back to the content value.

mode

Defines how to edit a line. One of the following options is required:

ensure
If line does not exist, it will be added. If before and after are specified either zero lines, or lines that contain the content line are allowed to be in between before and after. If there are lines, and none of them match then it will produce an error.
replace
If line already exists, it will be replaced.
delete
Delete the line, if found.
insert
Nearly identical to ensure. If a line does not exist, it will be added.

The differences are that multiple (and non-matching) lines are alloweed between before and after, if they are specified. The line will always be inserted right before before. insert also allows the use of location to specify that the line should be added at the beginning or end of the file.

Note

If mode=insert is used, at least one of the following options must also be defined: location, before, or after. If location is used, it takes precedence over the other two options.

location

In mode=insert only, whether to place the content at the beginning or end of a the file. If location is provided, before and after are ignored. Valid locations:

start
Place the content at the beginning of the file.
end
Place the content at the end of the file.

before

Regular expression or an exact case-sensitive fragment of the string. Will be tried as both a regex and a part of the line. Must match exactly one line in the file. This value is only used in ensure and insert modes. The content will be inserted just before this line, matching its indent unless indent=False.

after

Regular expression or an exact case-sensitive fragment of the string. Will be tried as both a regex and a part of the line. Must match exactly one line in the file. This value is only used in ensure and insert modes. The content will be inserted directly after this line, unless before is also provided. If before is not matched, indentation will match this line, unless indent=False.

show_changes

Output a unified diff of the old file and the new file. If False return a boolean if any changes were made. Default is True

Note

Using this option will store two copies of the file in-memory (the original version and the edited version) in order to generate the diff.

backup

Create a backup of the original file with the extension: "Year-Month-Day-Hour-Minutes-Seconds".

quiet

Do not raise any exceptions. E.g. ignore the fact that the file that is tried to be edited does not exist and nothing really happened.

indent

Keep indentation with the previous line. This option is not considered when the delete mode is specified. Default is True.

create

Create an empty file if doesn't exist.

New in version 2016.11.0.

user

The user to own the file, this defaults to the user salt is running as on the minion.

New in version 2016.11.0.

group

The group ownership set for the file, this defaults to the group salt is running as on the minion On Windows, this is ignored.

New in version 2016.11.0.

file_mode

The permissions to set on this file, aka 644, 0775, 4664. Not supported on Windows.

New in version 2016.11.0.

If an equal sign (=) appears in an argument to a Salt command, it is interpreted as a keyword argument in the format of key=val. That processing can be bypassed in order to pass an equal sign through to the remote shell command by manually specifying the kwarg:

update_config:
  file.line:
    - name: /etc/myconfig.conf
    - mode: ensure
    - content: my key = my value
    - before: somekey.*?

Examples:

Here's a simple config file.

[some_config]
# Some config file
# this line will go away

here=False
away=True
goodybe=away

And an sls file:

remove_lines:
  file.line:
    - name: /some/file.conf
    - mode: delete
    - match: away

This will produce:

[some_config]
# Some config file

here=False
away=True
goodbye=away

If that state is executed 2 more times, this will be the result:

[some_config]
# Some config file

here=False

Given that original file with this state:

replace_things:
  file.line:
    - name: /some/file.conf
    - mode: replace
    - match: away
    - content: here

Three passes will this state will result in this file:

[some_config]
# Some config file
here

here=False
here
here

Each pass replacing the first line found.

Given this file:

insert after me
something
insert before me

The following state:

insert_a_line:
  file.line:
    - name: /some/file.txt
    - mode: insert
    - after: insert after me
    - before: insert before me
    - content: thrice

If this state is executed 3 times, the result will be:

insert after me
something
thrice
thrice
thrice
insert before me

If the mode is ensure instead, it will fail each time. To succeed, we need to remove the incorrect line between before and after:

insert after me
insert before me

With an ensure mode, this will insert thrice the first time and make no changes for subsequent calls. For something simple this is fine, but if you have instead blocks like this:

Begin SomeBlock
    foo = bar
End

Begin AnotherBlock
    another = value
End

And given this state:

ensure_someblock:
  file.line:
    - name: /some/file.conf
    - mode: ensure
    - after: Begin SomeBlock
    - content: this = should be my content
    - before: End

This will fail because there are multiple End lines. Without that problem, it still would fail because there is a non-matching line, foo = bar. Ensure only allows either zero, or the matching line present to be present in between before and after.

Manage a given file, this function allows for a file to be downloaded from the salt master and potentially run through a templating system.

name

The location of the file to manage, as an absolute path.

source

The source file to download to the minion, this source file can be hosted on either the salt master server (salt://), the salt minion local file system (/), or on an HTTP or FTP server (http(s)://, ftp://).

Both HTTPS and HTTP are supported as well as downloading directly from Amazon S3 compatible URLs with both pre-configured and automatic IAM credentials. (see s3.get state documentation) File retrieval from Openstack Swift object storage is supported via swift://container/object_path URLs, see swift.get documentation. For files hosted on the salt file server, if the file is located on the master in the directory named spam, and is called eggs, the source string is salt://spam/eggs. If source is left blank or None (use ~ in YAML), the file will be created as an empty file and the content will not be managed. This is also the case when a file already exists and the source is undefined; the contents of the file will not be changed or managed. If source is left blank or None, please also set replaced to False to make your intention explicit.

If the file is hosted on a HTTP or FTP server then the source_hash argument is also required.

A list of sources can also be passed in to provide a default source and a set of fallbacks. The first source in the list that is found to exist will be used and subsequent entries in the list will be ignored. Source list functionality only supports local files and remote files hosted on the salt master server or retrievable via HTTP, HTTPS, or FTP.

file_override_example:
  file.managed:
    - source:
      - salt://file_that_does_not_exist
      - salt://file_that_exists

source_hash

This can be one of the following:

a source hash string
the URI of a file that contains source hash strings

The function accepts the first encountered long unbroken alphanumeric string of correct length as a valid hash, in order from most secure to least secure:

Type    Length
======  ======
sha512     128
sha384      96
sha256      64
sha224      56
sha1        40
md5         32

Using a Source Hash File

The file can contain several checksums for several files. Each line must contain both the file name and the hash. If no file name is matched, the first hash encountered will be used, otherwise the most secure hash with the correct source file name will be used.

When using a source hash file the source_hash argument needs to be a url, the standard download urls are supported, ftp, http, salt etc:

Example:

tomdroid-src-0.7.3.tar.gz:
  file.managed:
    - name: /tmp/tomdroid-src-0.7.3.tar.gz
    - source: https://launchpad.net/tomdroid/beta/0.7.3/+download/tomdroid-src-0.7.3.tar.gz
    - source_hash: https://launchpad.net/tomdroid/beta/0.7.3/+download/tomdroid-src-0.7.3.hash

The following lines are all supported formats:

/etc/rc.conf ef6e82e4006dee563d98ada2a2a80a27
sha254c8525aee419eb649f0233be91c151178b30f0dff8ebbdcc8de71b1d5c8bcc06a  /etc/resolv.conf
ead48423703509d37c4a90e6a0d53e143b6fc268

Debian file type *.dsc files are also supported.

Inserting the Source Hash in the SLS Data

The source_hash can be specified as a simple checksum, like so:

tomdroid-src-0.7.3.tar.gz:
  file.managed:
    - name: /tmp/tomdroid-src-0.7.3.tar.gz
    - source: https://launchpad.net/tomdroid/beta/0.7.3/+download/tomdroid-src-0.7.3.tar.gz
    - source_hash: 79eef25f9b0b2c642c62b7f737d4f53f

Note

Releases prior to 2016.11.0 must also include the hash type, like in the below example:

tomdroid-src-0.7.3.tar.gz:
  file.managed:
    - name: /tmp/tomdroid-src-0.7.3.tar.gz
    - source: https://launchpad.net/tomdroid/beta/0.7.3/+download/tomdroid-src-0.7.3.tar.gz
    - source_hash: md5=79eef25f9b0b2c642c62b7f737d4f53f

source_hash is ignored if the file hosted is not on a HTTP, HTTPS or FTP server.

Known issues:

If the remote server URL has the hash file as an apparent sub-directory of the source file, the module will discover that it has already cached a directory where a file should be cached. For example:

tomdroid-src-0.7.3.tar.gz:
  file.managed:
    - name: /tmp/tomdroid-src-0.7.3.tar.gz
    - source: https://launchpad.net/tomdroid/beta/0.7.3/+download/tomdroid-src-0.7.3.tar.gz
    - source_hash: https://launchpad.net/tomdroid/beta/0.7.3/+download/tomdroid-src-0.7.3.tar.gz/+md5

source_hash_name

When source_hash refers to a hash file, Salt will try to find the correct hash by matching the filename/URI associated with that hash. By default, Salt will look for the filename being managed. When managing a file at path /tmp/foo.txt, then the following line in a hash file would match:

acbd18db4cc2f85cedef654fccc4a4d8    foo.txt

However, sometimes a hash file will include multiple similar paths:

37b51d194a7513e45b56f6524f2d51f2    ./dir1/foo.txt
acbd18db4cc2f85cedef654fccc4a4d8    ./dir2/foo.txt
73feffa4b7f6bb68e44cf984c85f6e88    ./dir3/foo.txt

In cases like this, Salt may match the incorrect hash. This argument can be used to tell Salt which filename to match, to ensure that the correct hash is identified. For example:

/tmp/foo.txt:
  file.managed:
    - source: https://mydomain.tld/dir2/foo.txt
    - source_hash: https://mydomain.tld/hashes
    - source_hash_name: ./dir2/foo.txt

Note

This argument must contain the full filename entry from the checksum file, as this argument is meant to disambiguate matches for multiple files that have the same basename. So, in the example above, simply using foo.txt would not match.

New in version 2016.3.5.

keep_source

Set to False to discard the cached copy of the source file once the state completes. This can be useful for larger files to keep them from taking up space in minion cache. However, keep in mind that discarding the source file might result in the state needing to re-download the source file if the state is run again. If the source is not a local or salt:// one, the source hash is known, skip_verify is not true and the managed file exists with the correct hash and is not templated, this is not the case (i.e. remote downloads are avoided if the local hash matches the expected one).

New in version 2017.7.3.

user

The user to own the file, this defaults to the user salt is running as on the minion

group

The group ownership set for the file, this defaults to the group salt is running as on the minion. On Windows, this is ignored

mode

The permissions to set on this file, e.g. 644, 0775, or 4664.

The default mode for new files and directories corresponds to the umask of the salt process. The mode of existing files and directories will only be changed if mode is specified.

Note

This option is not supported on Windows.

Changed in version 2016.11.0: This option can be set to keep, and Salt will keep the mode from the Salt fileserver. This is only supported when the source URL begins with salt://, or for files local to the minion. Because the source option cannot be used with any of the contents options, setting the mode to keep is also incompatible with the contents options.

Note

keep does not work with salt-ssh.

As a consequence of how the files are transferred to the minion, and the inability to connect back to the master with salt-ssh, salt is unable to stat the file as it exists on the fileserver and thus cannot mirror the mode on the salt-ssh minion

attrs

The attributes to have on this file, e.g. a, i. The attributes can be any or a combination of the following characters: aAcCdDeijPsStTu.

Note

This option is not supported on Windows.

New in version 2018.3.0.

template

If this setting is applied, the named templating engine will be used to render the downloaded file. The following templates are supported:

cheetah
genshi
jinja
mako
py
wempy

makedirs

If set to True, then the parent directories will be created to facilitate the creation of the named file. If False, and the parent directory of the destination file doesn't exist, the state will fail.

dir_mode

The default mode for new files and directories corresponds umask of salt process. For existing files and directories it's not enforced.

replace

If set to False and the file already exists, the file will not be modified even if changes would otherwise be made. Permissions and ownership will still be enforced, however.

context

Overrides default context variables passed to the template.

defaults

Default context passed to the template.

backup

Overrides the default backup mode for this specific file. See backup_mode documentation for more details.

show_changes

Output a unified diff of the old file and the new file. If False return a boolean if any changes were made.

create

If set to False, then the file will only be managed if the file already exists on the system.

contents

Specify the contents of the file. Cannot be used in combination with source. Ignores hashes and does not use a templating engine.

This value can be either a single string, a multiline YAML string or a list of strings. If a list of strings, then the strings will be joined together with newlines in the resulting file. For example, the below two example states would result in identical file contents:

/path/to/file1:
  file.managed:
    - contents:
      - This is line 1
      - This is line 2

/path/to/file2:
  file.managed:
    - contents: |
        This is line 1
        This is line 2

contents_pillar

New in version 0.17.0.

Changed in version 2016.11.0: contents_pillar can also be a list, and the pillars will be concatenated together to form one file.

Operates like contents, but draws from a value stored in pillar, using the pillar path syntax used in pillar.get. This is useful when the pillar value contains newlines, as referencing a pillar variable using a jinja/mako template can result in YAML formatting issues due to the newlines causing indentation mismatches.

For example, the following could be used to deploy an SSH private key:

/home/deployer/.ssh/id_rsa:
  file.managed:
    - user: deployer
    - group: deployer
    - mode: 600
    - attrs: a
    - contents_pillar: userdata:deployer:id_rsa

This would populate /home/deployer/.ssh/id_rsa with the contents of pillar['userdata']['deployer']['id_rsa']. An example of this pillar setup would be like so:

userdata:
  deployer:
    id_rsa: |
        -----BEGIN RSA PRIVATE KEY-----
        MIIEowIBAAKCAQEAoQiwO3JhBquPAalQF9qP1lLZNXVjYMIswrMe2HcWUVBgh+vY
        U7sCwx/dH6+VvNwmCoqmNnP+8gTPKGl1vgAObJAnMT623dMXjVKwnEagZPRJIxDy
        B/HaAre9euNiY3LvIzBTWRSeMfT+rWvIKVBpvwlgGrfgz70m0pqxu+UyFbAGLin+
        GpxzZAMaFpZw4sSbIlRuissXZj/sHpQb8p9M5IeO4Z3rjkCP1cxI
        -----END RSA PRIVATE KEY-----

Note

The private key above is shortened to keep the example brief, but shows how to do multiline string in YAML. The key is followed by a pipe character, and the multiline string is indented two more spaces.

To avoid the hassle of creating an indented multiline YAML string, the file_tree external pillar can be used instead. However, this will not work for binary files in Salt releases before 2015.8.4.

Note

For information on using Salt Slots and how to incorporate execution module returns into file content or data, refer to the Salt Slots documentation.

contents_grains

New in version 2014.7.0.

Operates like contents, but draws from a value stored in grains, using the grains path syntax used in grains.get. This functionality works similarly to contents_pillar, but with grains.

For example, the following could be used to deploy a "message of the day" file:

write_motd:
  file.managed:
    - name: /etc/motd
    - contents_grains: motd

This would populate /etc/motd file with the contents of the motd grain. The motd grain is not a default grain, and would need to be set prior to running the state:

salt '*' grains.set motd 'Welcome! This system is managed by Salt.'

contents_newline

New in version 2014.7.0.

Changed in version 2015.8.4: This option is now ignored if the contents being deployed contain binary data.

If True, files managed using contents, contents_pillar, or contents_grains will have a newline added to the end of the file if one is not present. Setting this option to False will ensure the final line, or entry, does not contain a new line. If the last line, or entry in the file does contain a new line already, this option will not remove it.

contents_delimiter

New in version 2015.8.4.

Can be used to specify an alternate delimiter for contents_pillar or contents_grains. This delimiter will be passed through to pillar.get or grains.get when retrieving the contents.

encoding

If specified, then the specified encoding will be used. Otherwise, the file will be encoded using the system locale (usually UTF-8). See https://docs.python.org/3/library/codecs.html#standard-encodings for the list of available encodings.

New in version 2017.7.0.

encoding_errors

Error encoding scheme. Default is `'strict'`. See https://docs.python.org/2/library/codecs.html#codec-base-classes for the list of available schemes.

New in version 2017.7.0.

allow_empty

New in version 2015.8.4.

If set to False, then the state will fail if the contents specified by contents_pillar or contents_grains are empty.

follow_symlinks

New in version 2014.7.0.

If the desired path is a symlink follow it and make changes to the file to which the symlink points.

check_cmd

New in version 2014.7.0.

The specified command will be run with an appended argument of a temporary file containing the new managed contents. If the command exits with a zero status the new managed contents will be written to the managed destination. If the command exits with a nonzero exit code, the state will fail and no changes will be made to the file.

For example, the following could be used to verify sudoers before making changes:

/etc/sudoers:
  file.managed:
    - user: root
    - group: root
    - mode: 0440
    - attrs: i
    - source: salt://sudoers/files/sudoers.jinja
    - template: jinja
    - check_cmd: /usr/sbin/visudo -c -f

NOTE: This check_cmd functions differently than the requisite check_cmd.

tmp_dir

Directory for temp file created by check_cmd. Useful for checkers dependent on config file location (e.g. daemons restricted to their own config directories by an apparmor profile).

/etc/dhcp/dhcpd.conf:
  file.managed:
    - user: root
    - group: root
    - mode: 0755
    - tmp_dir: '/etc/dhcp'
    - contents: "# Managed by Salt"
    - check_cmd: dhcpd -t -cf

tmp_ext

Suffix for temp file created by check_cmd. Useful for checkers dependent on config file extension (e.g. the init-checkconf upstart config checker).

/etc/init/test.conf:
  file.managed:
    - user: root
    - group: root
    - mode: 0440
    - tmp_ext: '.conf'
    - contents:
      - 'description "Salt Minion"'
      - 'start on started mountall'
      - 'stop on shutdown'
      - 'respawn'
      - 'exec salt-minion'
    - check_cmd: init-checkconf -f

skip_verify

If True, hash verification of remote file sources (http://, https://, ftp://) will be skipped, and the source_hash argument will be ignored.

New in version 2016.3.0.

selinux

Allows setting the selinux user, role, type, and range of a managed file

/tmp/selinux.test
  file.managed:
    - user: root
    - selinux:
        seuser: system_u
        serole: object_r
        setype: system_conf_t
        serange: s0

New in version 3000.

win_owner

The owner of the directory. If this is not passed, user will be used. If user is not passed, the account under which Salt is running will be used.

New in version 2017.7.0.

win_perms

A dictionary containing permissions to grant and their propagation. For example: {'Administrators': {'perms': 'full_control'}} Can be a single basic perm or a list of advanced perms. perms must be specified. applies_to does not apply to file objects.

New in version 2017.7.0.

win_deny_perms

A dictionary containing permissions to deny and their propagation. For example: {'Administrators': {'perms': 'full_control'}} Can be a single basic perm or a list of advanced perms. perms must be specified. applies_to does not apply to file objects.

New in version 2017.7.0.

win_inheritance

True to inherit permissions from the parent directory, False not to inherit permission.

New in version 2017.7.0.

win_perms_reset

If True the existing DACL will be cleared and replaced with the settings defined in this function. If False, new entries will be appended to the existing DACL. Default is False.

New in version 2018.3.0.

Here's an example using the above win_* parameters:

create_config_file:
  file.managed:
    - name: C:\config\settings.cfg
    - source: salt://settings.cfg
    - win_owner: Administrators
    - win_perms:
        # Basic Permissions
        dev_ops:
          perms: full_control
        # List of advanced permissions
        appuser:
          perms:
            - read_attributes
            - read_ea
            - create_folders
            - read_permissions
        joe_snuffy:
          perms: read
    - win_deny_perms:
        fred_snuffy:
          perms: full_control
    - win_inheritance: False

verify_ssl: If False, remote https file sources (https://) and source_hash will not attempt to validate the servers certificate. Default is True.

New in version 3002.
use_etag: If True, remote http/https file sources will attempt to use the ETag header to determine if the remote file needs to be downloaded. This provides a lightweight mechanism for promptly refreshing files changed on a web server without requiring a full hash comparison via the source_hash parameter.

New in version 3005.
signature: Ensure a valid signature exists on the selected source file. Set this to true for inline signatures, or to a file URI retrievable by :py:func:`cp.cache_file <salt.modules.cp.cache_file> for a detached one.

Note

A signature is only enforced directly after caching the file, before it is moved to its final destination. Existing target files (with the correct checksum) will neither be checked nor deleted.

It will be enforced regardless of source type and will be required on the final output, therefore this does not lend itself well when templates are rendered. The file will not be modified, meaning inline signatures are not removed.

New in version 3007.0.
source_hash_sig: When source is a remote file source, source_hash is a file, skip_verify is not true and use_etag is not true, ensure a valid signature exists on the source hash file. Set this to true for an inline (clearsigned) signature, or to a file URI retrievable by :py:func:`cp.cache_file <salt.modules.cp.cache_file> for a detached one.

Note

A signature on the source_hash file is enforced regardless of changes since its contents are used to check if an existing file is in the correct state - but only for remote sources! As for signature, existing target files will not be modified, only the cached source_hash and source_hash_sig files will be removed.

New in version 3007.0.
signed_by_any: When verifying signatures either on the managed file or its source hash file, require at least one valid signature from one of a list of keys. By default, this is passed to gpg.verify, meaning a key is identified by its fingerprint.

New in version 3007.0.
signed_by_all: When verifying signatures either on the managed file or its source hash file, require a valid signature from each of the keys in this list. By default, this is passed to gpg.verify, meaning a key is identified by its fingerprint.

New in version 3007.0.
keyring: When verifying signatures, use this keyring.

New in version 3007.0.
gnupghome: When verifying signatures, use this GnuPG home.

New in version 3007.0.
ignore_ordering: If True, changes in line order will be ignored ONLY for the purposes of triggering watch/onchanges requisites. Changes will still be made to the file to bring it into alignment with requested state, and also reported during the state run. This behavior is useful for bringing existing application deployments under Salt configuration management without disrupting production applications with a service restart.

New in version 3007.0.
ignore_whitespace: If True, changes in whitespace will be ignored ONLY for the purposes of triggering watch/onchanges requisites. Changes will still be made to the file to bring it into alignment with requested state, and also reported during the state run. This behavior is useful for bringing existing application deployments under Salt configuration management without disrupting production applications with a service restart. Implies ignore_ordering=True

New in version 3007.0.
ignore_comment_characters: If set to a chacter string, the presence of changes after that string will be ignored in changes found in the file ONLY for the purposes of triggering watch/onchanges requisites. Changes will still be made to the file to bring it into alignment with requested state, and also reported during the state run. This behavior is useful for bringing existing application deployments under Salt configuration management without disrupting production applications with a service restart. Implies ignore_ordering=True

New in version 3007.0.
new_file_diff: If True, creation of new files will still show a diff in the changes return.

New in version 3008.0.
sig_backend: When verifying signatures, use this execution module as a backend. It must be compatible with the gpg.verify API. Defaults to gpg. All signature-related parameters are passed through.

New in version 3008.0.

salt.states.file.missing(name, **kwargs)¶

Verify that the named file or directory is missing, this returns True only if the named file is missing but does not remove the file if it is present.

name: Absolute path which must NOT exist

salt.states.file.mknod(name, ntype, major=0, minor=0, user=None, group=None, mode='0600')¶

Create a special file similar to the 'nix mknod command. The supported device types are p (fifo pipe), c (character device), and b (block device). Provide the major and minor numbers when specifying a character device or block device. A fifo pipe does not require this information. The command will create the necessary dirs if needed. If a file of the same name not of the same type/major/minor exists, it will not be overwritten or unlinked (deleted). This is logically in place as a safety measure because you can really shoot yourself in the foot here and it is the behavior of 'nix mknod. It is also important to note that not just anyone can create special devices. Usually this is only done as root. If the state is executed as none other than root on a minion, you may receive a permission error.

name: name of the file
ntype: node type 'p' (fifo pipe), 'c' (character device), or 'b' (block device)
major: major number of the device does not apply to a fifo pipe
minor: minor number of the device does not apply to a fifo pipe
user: owning user of the device/pipe
group: owning group of the device/pipe
mode: permissions on the device/pipe

Usage:

/dev/chr:
  file.mknod:
    - ntype: c
    - major: 180
    - minor: 31
    - user: root
    - group: root
    - mode: 660

/dev/blk:
  file.mknod:
    - ntype: b
    - major: 8
    - minor: 999
    - user: root
    - group: root
    - mode: 660

/dev/fifo:
  file.mknod:
    - ntype: p
    - user: root
    - group: root
    - mode: 660

New in version 0.17.0.

salt.states.file.mod_beacon(name, **kwargs)¶: Create a beacon to monitor a file based on a beacon state argument.

Note

This state exists to support special handling of the beacon state argument for supported state functions. It should not be called directly.

salt.states.file.mod_run_check_cmd(cmd, filename, **check_cmd_opts)¶

Execute the check_cmd logic.

Return True if check_cmd succeeds (check_cmd == 0) otherwise return a result dict

salt.states.file.not_cached(name, saltenv='base')¶

New in version 2017.7.3.

Ensures that a file is not present in the minion's cache, deleting it if found. This state is primarily invoked by other states to ensure that a fresh copy is fetched.

name: The URL of the file to be removed from cache. To remove a file from cache in an environment other than base, either use the saltenv argument or include the saltenv in the URL (e.g. salt://path/to/file.conf?saltenv=dev).

Note

A list of URLs is not supported, this must be a single URL. If a local file is passed here, the state will take no action.
saltenv: Used to specify the environment from which to download a file from the Salt fileserver (i.e. those with salt:// URL).

salt.states.file.patch(name, source=None, source_hash=None, source_hash_name=None, skip_verify=False, template=None, context=None, defaults=None, options='', reject_file=None, strip=None, saltenv=None, **kwargs)¶

Ensure that a patch has been applied to the specified file or directory

Changed in version 2019.2.0: The hash and dry_run_first options are now ignored, as the logic which determines whether or not the patch has already been applied no longer requires them. Additionally, this state now supports patch files that modify more than one file. To use these sort of patches, specify a directory (and, if necessary, the strip option) instead of a file.

Note

A suitable patch executable must be available on the minion. Also, keep in mind that the pre-check this state does to determine whether or not changes need to be made will create a temp file and send all patch output to that file. This means that, in the event that the patch would not have applied cleanly, the comment included in the state results will reference a temp file that will no longer exist once the state finishes running.

name

The file or directory to which the patch should be applied

source

The patch file to apply

Changed in version 2019.2.0: The source can now be from any file source supported by Salt (salt://, http://, https://, ftp://, etc.). Templating is also now supported.

source_hash

Works the same way as in file.managed.

New in version 2019.2.0.

source_hash_name

Works the same way as in file.managed

New in version 2019.2.0.

skip_verify

Works the same way as in file.managed

New in version 2019.2.0.

template

Works the same way as in file.managed

New in version 2019.2.0.

context

Works the same way as in file.managed

New in version 2019.2.0.

defaults

Works the same way as in file.managed

New in version 2019.2.0.

options

Extra options to pass to patch. This should not be necessary in most cases.

Note

For best results, short opts should be separate from one another. The -N and -r, and -o options are used internally by this state and cannot be used here. Additionally, instead of using -pN or --strip=N, use the strip option documented below.

reject_file

If specified, any rejected hunks will be written to this file. If not specified, then they will be written to a temp file which will be deleted when the state finishes running.

Important

The parent directory must exist. Also, this will overwrite the file if it is already present.

New in version 2019.2.0.

strip

Number of directories to strip from paths in the patch file. For example, using the below SLS would instruct Salt to use -p1 when applying the patch:

/etc/myfile.conf:
  file.patch:
    - source: salt://myfile.patch
    - strip: 1

New in version 2019.2.0: In previous versions, -p1 would need to be passed as part of the options value.

saltenv

Specify the environment from which to retrieve the patch file indicated by the source parameter. If not provided, this defaults to the environment from which the state is being executed.

Note

Ignored when the patch file is from a non-salt:// source.

Usage:

# Equivalent to ``patch --forward /opt/myfile.txt myfile.patch``
/opt/myfile.txt:
  file.patch:
    - source: salt://myfile.patch

salt.states.file.prepend(name, text=None, makedirs=False, source=None, source_hash=None, template='jinja', sources=None, source_hashes=None, defaults=None, context=None, header=None)¶

Ensure that some text appears at the beginning of a file

The text will not be prepended again if it already exists in the file. You may specify a single line of text or a list of lines to append.

name

The location of the file to prepend to.

text

The text to be prepended, which can be a single string or a list of strings.

makedirs

source

A single source file to prepend. This source file can be hosted on either the salt master server, or on an HTTP or FTP server. Both HTTPS and HTTP are supported as well as downloading directly from Amazon S3 compatible URLs with both pre-configured and automatic IAM credentials (see s3.get state documentation). File retrieval from Openstack Swift object storage is supported via swift://container/object_path URLs (see swift.get documentation).

For files hosted on the salt file server, if the file is located on the master in the directory named spam, and is called eggs, the source string is salt://spam/eggs.

If the file is hosted on an HTTP or FTP server, the source_hash argument is also required.

source_hash

This can be one of the following:

a source hash string
the URI of a file that contains source hash strings

The function accepts the first encountered long unbroken alphanumeric string of correct length as a valid hash, in order from most secure to least secure:

Type    Length
======  ======
sha512     128
sha384      96
sha256      64
sha224      56
sha1        40
md5         32

See the source_hash parameter description for file.managed function for more details and examples.

template

The named templating engine will be used to render the source file(s). Defaults to jinja. The following templates are supported:

cheetah

sources

A list of source files to prepend. If the files are hosted on an HTTP or FTP server, the source_hashes argument is also required.

source_hashes

A list of source_hashes corresponding to the sources list specified in the sources argument.

defaults

Default context passed to the template.

context

Overrides default context variables passed to the template.

ignore_whitespace

New in version 2015.8.4.

header

Forces the text to be prepended. If it exists in the file but not at the beginning, then it prepends a duplicate.

Multi-line example:

/etc/motd:
  file.prepend:
    - text: |
        Thou hadst better eat salt with the Philosophers of Greece,
        than sugar with the Courtiers of Italy.
        - Benjamin Franklin

Multiple lines of text:

/etc/motd:
  file.prepend:
    - text:
      - Trust no one unless you have eaten much salt with him.
      - "Salt is born of the purest of parents: the sun and the sea."

Optionally, require the text to appear exactly as specified (order and position). Combine with multi-line or multiple lines of input.

/etc/motd:
  file.prepend:
    - header: True
    - text:
      - This will be the very first line in the file.
      - The 2nd line, regardless of duplicates elsewhere in the file.
      - These will be written anew if they do not appear verbatim.

Gather text from multiple template files:

/etc/motd:
  file:
    - prepend
    - template: jinja
    - sources:
      - salt://motd/devops-messages.tmpl
      - salt://motd/hr-messages.tmpl
      - salt://motd/general-messages.tmpl

salt.states.file.pruned(name, recurse=False, ignore_errors=False, older_than=None)¶

New in version 3006.0.

Ensure that the named directory is absent. If it exists and is empty, it will be deleted. An entire directory tree can be pruned of empty directories as well, by using the recurse option.

name: The directory which should be deleted if empty.
recurse: If set to True, this option will recursive deletion of empty directories. This is useful if nested paths are all empty, and would be the only items preventing removal of the named root directory.
ignore_errors: If set to True, any errors encountered while attempting to delete a directory are ignored. This AUTOMATICALLY ENABLES the recurse option since it's not terribly useful to ignore errors on the removal of a single directory. Useful for pruning only the empty directories in a tree which contains non-empty directories as well.
older_than: When older_than is set to a number, it is used to determine the number of days which must have passed since the last modification timestamp before a directory will be allowed to be removed. Setting the value to 0 is equivalent to leaving it at the default of None.

salt.states.file.recurse(name, source, keep_source=True, clean=False, require=None, user=None, group=None, dir_mode=None, file_mode=None, sym_mode=None, template=None, context=None, replace=True, defaults=None, include_empty=False, backup='', include_pat=None, exclude_pat=None, maxdepth=None, keep_symlinks=False, force_symlinks=False, win_owner=None, win_perms=None, win_deny_perms=None, win_inheritance=True, **kwargs)¶

Recurse through a subdirectory on the master and copy said subdirectory over to the specified path.

name

The directory to set the recursion in

source

The source directory, this directory is located on the salt master file server and is specified with the salt:// protocol. If the directory is located on the master in the directory named spam, and is called eggs, the source string is salt://spam/eggs

keep_source

New in version 2017.7.3.

clean

Make sure that only files that are set up by salt and required by this function are kept. If this option is set then everything in this directory will be deleted unless it is required.

require

Require other resources such as packages or files

user

The user to own the directory. This defaults to the user salt is running as on the minion

group

The group ownership set for the directory. This defaults to the group salt is running as on the minion. On Windows, this is ignored

dir_mode

The permissions mode to set on any directories created.

The default mode for new files and directories corresponds umask of salt process. For existing files and directories it's not enforced.

Note

This option is not supported on Windows.

file_mode

The permissions mode to set on any files created.

The default mode for new files and directories corresponds umask of salt process. For existing files and directories it's not enforced.

Note

This option is not supported on Windows.

sym_mode

The permissions mode to set on any symlink created.

The default mode for new files and directories corresponds umask of salt process. For existing files and directories it's not enforced.

Note

This option is not supported on Windows.

template

If this setting is applied, the named templating engine will be used to render the downloaded file. The following templates are supported:

cheetah
genshi
jinja
mako
py
wempy

Note

The template option is required when recursively applying templates.

replace

If set to False and the file already exists, the file will not be modified even if changes would otherwise be made. Permissions and ownership will still be enforced, however.

context

Overrides default context variables passed to the template.

defaults

Default context passed to the template.

include_empty

Set this to True if empty directories should also be created (default is False)

backup

Overrides the default backup mode for all replaced files. See backup_mode documentation for more details.

include_pat

When copying, include only this pattern, or list of patterns, from the source. Default is glob match; if prefixed with 'E@', then regexp match. Example:

- include_pat: hello*       :: glob matches 'hello01', 'hello02'
                               ... but not 'otherhello'
- include_pat: E@hello      :: regexp matches 'otherhello',
                               'hello01' ...

Changed in version 3001: List patterns are now supported

- include_pat:
    - hello01
    - hello02

exclude_pat

Exclude this pattern, or list of patterns, from the source when copying. If both include_pat and exclude_pat are supplied, then it will apply conditions cumulatively. i.e. first select based on include_pat, and then within that result apply exclude_pat.

Also, when 'clean=True', exclude this pattern from the removal list and preserve in the destination. Example:

- exclude_pat: APPDATA*               :: glob matches APPDATA.01,
                                         APPDATA.02,.. for exclusion
- exclude_pat: E@(APPDATA)|(TEMPDATA) :: regexp matches APPDATA
                                         or TEMPDATA for exclusion

Changed in version 3001: List patterns are now supported

- exclude_pat:
    - APPDATA.01
    - APPDATA.02

maxdepth

When copying, only copy paths which are of depth maxdepth from the source path. Example:

- maxdepth: 0      :: Only include files located in the source
                      directory
- maxdepth: 1      :: Only include files located in the source
                      or immediate subdirectories

keep_symlinks

Keep symlinks when copying from the source. This option will cause the copy operation to terminate at the symlink. If desire behavior similar to rsync, then set this to True. This option is not taken in account if fileserver_followsymlinks is set to False.

force_symlinks

Force symlink creation. This option will force the symlink creation. If a file or directory is obstructing symlink creation it will be recursively removed so that symlink creation can proceed. This option is usually not needed except in special circumstances. This option is not taken in account if fileserver_followsymlinks is set to False.

win_owner

The owner of the symlink and directories if makedirs is True. If this is not passed, user will be used. If user is not passed, the account under which Salt is running will be used.

New in version 2017.7.7.

win_perms

A dictionary containing permissions to grant

New in version 2017.7.7.

win_deny_perms

A dictionary containing permissions to deny

New in version 2017.7.7.

win_inheritance

True to inherit permissions from parent, otherwise False

New in version 2017.7.7.

salt.states.file.rename(name, source, force=False, makedirs=False, **kwargs)¶

If the source file exists on the system, rename it to the named file. The named file will not be overwritten if it already exists unless the force option is set to True.

name: The location of the file to rename to
source: The location of the file to move to the location specified with name
force: If the target location is present then the file will not be moved, specify "force: True" to overwrite the target file
makedirs: If the target subdirectories don't exist create them

salt.states.file.replace(name, pattern, repl, count=0, flags=8, bufsize=1, append_if_not_found=False, prepend_if_not_found=False, not_found_content=None, backup='.bak', show_changes=True, ignore_if_missing=False, backslash_literal=False)¶

Maintain an edit in a file.

New in version 0.17.0.

name

Filesystem path to the file to be edited. If a symlink is specified, it will be resolved to its target.

pattern

A regular expression, to be matched using Python's re.search().

Note

If you need to match a literal string that contains regex special characters, you may want to use salt's custom Jinja filter, regex_escape.

{{ 'http://example.com?foo=bar%20baz' | regex_escape }}

repl

The replacement text

count

Maximum number of pattern occurrences to be replaced. Defaults to 0. If count is a positive integer n, no more than n occurrences will be replaced, otherwise all occurrences will be replaced.

flags

A list of flags defined in the re module documentation from the Python standard library. Each list item should be a string that will correlate to the human-friendly flag name. E.g., ['IGNORECASE', 'MULTILINE']. Optionally, flags may be an int, with a value corresponding to the XOR (|) of all the desired flags. Defaults to 8 (which equates to ['MULTILINE']).

Note

file.replace reads the entire file as a string to support multiline regex patterns. Therefore, when using anchors such as ^ or $ in the pattern, those anchors may be relative to the line OR relative to the file. The default for file.replace is to treat anchors as relative to the line, which is implemented by setting the default value of flags to ['MULTILINE']. When overriding the default value for flags, if 'MULTILINE' is not present then anchors will be relative to the file. If the desired behavior is for anchors to be relative to the line, then simply add 'MULTILINE' to the list of flags.

bufsize

How much of the file to buffer into memory at once. The default value 1 processes one line at a time. The special value file may be specified which will read the entire file into memory before processing.

append_if_not_found

If set to True, and pattern is not found, then the content will be appended to the file.

New in version 2014.7.0.

prepend_if_not_found

If set to True and pattern is not found, then the content will be prepended to the file.

New in version 2014.7.0.

not_found_content

Content to use for append/prepend if not found. If None (default), uses repl. Useful when repl uses references to group in pattern.

New in version 2014.7.0.

backup

The file extension to use for a backup of the file before editing. Set to False to skip making a backup.

show_changes

Output a unified diff of the old file and the new file. If False return a boolean if any changes were made. Returns a boolean or a string.

ignore_if_missing

New in version 2016.3.4.

Controls what to do if the file is missing. If set to False, the state will display an error raised by the execution module. If set to True, the state will simply report no changes.

backslash_literal

New in version 2016.11.7.

Interpret backslashes as literal backslashes for the repl and not escape characters. This will help when using append/prepend so that the backslashes are not interpreted for the repl on the second run of the state.

For complex regex patterns, it can be useful to avoid the need for complex quoting and escape sequences by making use of YAML's multiline string syntax.

complex_search_and_replace:
  file.replace:
    # <...snip...>
    - pattern: |
        CentOS \(2.6.32[^\\n]+\\n\s+root[^\\n]+\\n\)+

Note

When using YAML multiline string syntax in pattern:, make sure to also use that syntax in the repl: part, or you might loose line feeds.

When regex capture groups are used in pattern:, their captured value is available for reuse in the repl: part as a backreference (ex. \1).

add_login_group_to_winbind_ssh_access_list:
  file.replace:
    - name: '/etc/security/pam_winbind.conf'
    - pattern: '^(require_membership_of = )(.*)$'
    - repl: '\1\2,append-new-group-to-line'

Note

The file.replace state uses Python's re module. For more advanced options, see https://docs.python.org/2/library/re.html

salt.states.file.retention_schedule(name, retain, strptime_format=None, timezone=None)¶

Apply retention scheduling to backup storage directory.

New in version 2016.11.0.

Changed in version 3006.0.

Parameters:

name -- The filesystem path to the directory containing backups to be managed.
retain --
Delete the backups, except for the ones we want to keep. The N below should be an integer but may also be the special value of all, which keeps all files matching the criteria. All of the retain options default to None, which means to not keep files based on this criteria.

most_recent N:

Keep the most recent N files.

first_of_hour N:

For the last N hours from now, keep the first file after the hour.

first_of_day N:

For the last N days from now, keep the first file after midnight. See also timezone.

first_of_week N:

For the last N weeks from now, keep the first file after Sunday midnight.

first_of_month N:

For the last N months from now, keep the first file after the start of the month.

first_of_year N:

For the last N years from now, keep the first file after the start of the year.
strptime_format -- A python strptime format string used to first match the filenames of backups and then parse the filename to determine the datetime of the file. https://docs.python.org/2/library/datetime.html#datetime.datetime.strptime Defaults to None, which considers all files in the directory to be backups eligible for deletion and uses os.path.getmtime() to determine the datetime.
timezone -- The timezone to use when determining midnight. This is only used when datetime is pulled from os.path.getmtime(). Defaults to None which uses the timezone from the locale.

Usage example:

/var/backups/example_directory:
  file.retention_schedule:
    - retain:
        most_recent: 5
        first_of_hour: 4
        first_of_day: 7
        first_of_week: 6    # NotImplemented yet.
        first_of_month: 6
        first_of_year: all
    - strptime_format: example_name_%Y%m%dT%H%M%S.tar.bz2
    - timezone: None

salt.states.file.serialize(name, dataset=None, dataset_pillar=None, user=None, group=None, mode=None, backup='', makedirs=False, show_changes=True, create=True, merge_if_exists=False, encoding=None, encoding_errors='strict', serializer=None, serializer_opts=None, deserializer_opts=None, check_cmd=None, tmp_dir=None, tmp_ext='', **kwargs)¶

Serializes dataset and store it into managed file. Useful for sharing simple configuration files.

name: The location of the file to create
dataset: The dataset that will be serialized
dataset_pillar: Operates like dataset, but draws from a value stored in pillar, using the pillar path syntax used in pillar.get. This is useful when the pillar value contains newlines, as referencing a pillar variable using a jinja/mako template can result in YAML formatting issues due to the newlines causing indentation mismatches.

New in version 2015.8.0.

Note

For information on using Salt Slots and how to incorporate execution module returns into file content or data, refer to the Salt Slots documentation.

serializer (or formatter)

Write the data as this format. See the list of serializer modules for supported output formats.

Changed in version 3002: serializer argument added as an alternative to formatter. Both are accepted, but using both will result in an error.

encoding

New in version 2017.7.0.

encoding_errors

Error encoding scheme. Default is `'strict'`. See https://docs.python.org/2/library/codecs.html#codec-base-classes for the list of available schemes.

New in version 2017.7.0.

user

The user to own the directory, this defaults to the user salt is running as on the minion

group

The group ownership set for the directory, this defaults to the group salt is running as on the minion

mode

The permissions to set on this file, e.g. 644, 0775, or 4664.

The default mode for new files and directories corresponds umask of salt process. For existing files and directories it's not enforced.

Note

This option is not supported on Windows.

backup

Overrides the default backup mode for this specific file.

makedirs

Create parent directories for destination file.

New in version 2014.1.3.

show_changes

Output a unified diff of the old file and the new file. If False return a boolean if any changes were made.

create

Default is True, if create is set to False then the file will only be managed if the file already exists on the system.

merge_if_exists

Default is False, if merge_if_exists is True then the existing file will be parsed and the dataset passed in will be merged with the existing content

New in version 2014.7.0.

serializer_opts

Pass through options to serializer. For example:

/etc/dummy/package.yaml
  file.serialize:
    - serializer: yaml
    - serializer_opts:
      - explicit_start: True
      - default_flow_style: True
      - indent: 4

The valid opts are the additional opts (i.e. not the data being serialized) for the function used to serialize the data. Documentation for the these functions can be found in the list below:

For yaml: yaml.dump()
For json: json.dumps()
For python: pprint.pformat()
For msgpack: Run python -c 'import msgpack; help(msgpack.Packer)' to see the available options (encoding, unicode_errors, etc.)

deserializer_opts

Like serializer_opts above, but only used when merging with an existing file (i.e. when merge_if_exists is set to True).

The options specified here will be passed to the deserializer to load the existing data, before merging with the specified data and re-serializing.

/etc/dummy/package.yaml
  file.serialize:
    - serializer: yaml
    - serializer_opts:
      - explicit_start: True
      - default_flow_style: True
      - indent: 4
    - deserializer_opts:
      - encoding: latin-1
    - merge_if_exists: True

The valid opts are the additional opts (i.e. not the data being deserialized) for the function used to deserialize the data. Documentation for the these functions can be found in the list below:

For yaml: yaml.load()
For json: json.loads()

However, note that not all arguments are supported. For example, when deserializing JSON, arguments like parse_float and parse_int which accept a callable object cannot be handled in an SLS file.

New in version 2019.2.0.

check_cmd

The specified command will be run with an appended argument of a temporary file containing the new file contents. If the command exits with a zero status the new file contents will be written to the state output destination. If the command exits with a nonzero exit code, the state will fail and no changes will be made to the file.

For example, the following could be used to verify sudoers before making changes:

/etc/consul.d/my_config.json:
  file.serialize:
    - dataset:
        datacenter: "east-aws"
        data_dir: "/opt/consul"
        log_level: "INFO"
        node_name: "foobar"
        server: true
        watches:
          - type: checks
            handler: "/usr/bin/health-check-handler.sh"
        telemetry:
          statsite_address: "127.0.0.1:2180"
    - serializer: json
    - check_cmd: consul validate

NOTE: This check_cmd functions differently than the requisite check_cmd.

New in version 3007.0.

tmp_dir

Directory for temp file created by check_cmd. Useful for checkers dependent on config file location (e.g. daemons restricted to their own config directories by an apparmor profile).

New in version 3007.0.

tmp_ext

Suffix for temp file created by check_cmd. Useful for checkers dependent on config file extension.

New in version 3007.0.

For example, this state:

/etc/dummy/package.json:
  file.serialize:
    - dataset:
        name: naive
        description: A package using naive versioning
        author: A confused individual <iam@confused.com>
        dependencies:
          express: '>= 1.2.0'
          optimist: '>= 0.1.0'
        engine: node 0.4.1
    - serializer: json

will manage the file /etc/dummy/package.json:

{
  "author": "A confused individual <iam@confused.com>",
  "dependencies": {
    "express": ">= 1.2.0",
    "optimist": ">= 0.1.0"
  },
  "description": "A package using naive versioning",
  "engine": "node 0.4.1",
  "name": "naive"
}

salt.states.file.shortcut(name, target, arguments=None, working_dir=None, description=None, icon_location=None, force=False, backupname=None, makedirs=False, user=None, **kwargs)¶

Create a Windows shortcut

If the file already exists and is a shortcut pointing to any location other than the specified target, the shortcut will be replaced. If it is a regular file or directory then the state will return False. If the regular file or directory is desired to be replaced with a shortcut pass force: True, if it is to be renamed, pass a backupname.

name

The location of the shortcut to create. Must end with either ".lnk" or ".url"

target

The location that the shortcut points to

arguments

Any arguments to pass in the shortcut

working_dir

Working directory in which to execute target

description

Description to set on shortcut

icon_location

Location of shortcut's icon

force

If the name of the shortcut exists and is not a file and force is set to False, the state will fail. If force is set to True, the link or directory in the way of the shortcut file will be deleted to make room for the shortcut, unless backupname is set, when it will be renamed

backupname

If the name of the shortcut exists and is not a file, it will be renamed to the backupname. If the backupname already exists and force is False, the state will fail. Otherwise, the backupname will be removed first.

makedirs

If the location of the shortcut does not already have a parent directory then the state will fail, setting makedirs to True will allow Salt to create the parent directory. Setting this to True will also create the parent for backupname if necessary.

user

The user to own the file, this defaults to the user salt is running as on the minion

The default mode for new files and directories corresponds umask of salt process. For existing files and directories it's not enforced.

salt.states.file.symlink(name, target, force=False, backupname=None, makedirs=False, user=None, group=None, mode=None, win_owner=None, win_perms=None, win_deny_perms=None, win_inheritance=None, atomic=False, disallow_copy_and_unlink=False, inherit_user_and_group=False, follow_symlinks=True, **kwargs)¶

Create a symbolic link (symlink, soft link)

If the file already exists and is a symlink pointing to any location other than the specified target, the symlink will be replaced. If an entry with the same name exists then the state will return False. If the existing entry is desired to be replaced with a symlink pass force: True, if it is to be renamed, pass a backupname.

name

The location of the symlink to create

target

The location that the symlink points to

force

If the name of the symlink exists and is not a symlink and force is set to False, the state will fail. If force is set to True, the existing entry in the way of the symlink file will be deleted to make room for the symlink, unless backupname is set, when it will be renamed

Changed in version 3000: Force will now remove all types of existing file system entries, not just files, directories and symlinks.

backupname

If the name of the symlink exists and is not a symlink, it will be renamed to the backupname. If the backupname already exists and force is False, the state will fail. Otherwise, the backupname will be removed first. An absolute path OR a basename file/directory name must be provided. The latter will be placed relative to the symlink destination's parent directory.

makedirs

If the location of the symlink does not already have a parent directory then the state will fail, setting makedirs to True will allow Salt to create the parent directory

user

The user to own the file, this defaults to the user salt is running as on the minion unless the link already exists and inherit_user_and_group is set

group

The group ownership set for the file, this defaults to the group salt is running as on the minion unless the link already exists and inherit_user_and_group is set. On Windows, this is ignored

mode

The permissions to set on this file, aka 644, 0775, 4664. Not supported on Windows.

The default mode for new files and directories corresponds umask of salt process. For existing files and directories it's not enforced.

win_owner

The owner of the symlink and directories if makedirs is True. If this is not passed, user will be used. If user is not passed, the account under which Salt is running will be used.

New in version 2017.7.7.

win_perms

A dictionary containing permissions to grant

New in version 2017.7.7.

win_deny_perms

A dictionary containing permissions to deny

New in version 2017.7.7.

win_inheritance

True to inherit permissions from parent, otherwise False

New in version 2017.7.7.

atomic

Use atomic file operation to create the symlink.

New in version 3006.0.

disallow_copy_and_unlink

Only used if backupname is used and the name of the symlink exists and is not a symlink. If set to True, the operation is offloaded to the file.rename execution module function. This will use os.rename underneath, which will fail in the event that src and dst are on different filesystems. If False (the default), shutil.move will be used in order to fall back on a "copy then unlink" approach, which is required for moving across filesystems.

New in version 3006.0.

inherit_user_and_group

If set to True, the link already exists, and either user or group are not set, this parameter will inform Salt to pull the user and group information from the existing link and use it where user or group is not set. The user and group parameters will override this behavior.

New in version 3006.0.

follow_symlinks (bool):

If set to False, the underlying file.symlink execution module and any checks in this state will use os.path.lexists() for existence checks instead of os.path.exists().

New in version 3007.0.

salt.states.file.tidied(name, age=0, matches=None, rmdirs=False, size=0, exclude=None, full_path_match=False, followlinks=False, time_comparison='atime', age_size_logical_operator='OR', age_size_only=None, rmlinks=True, **kwargs)¶

Changed in version 3005,3006.0.

Remove unwanted files based on specific criteria.

The default operation uses an OR operation to evaluate age and size, so a file that is too large but is not old enough will still get tidied. If neither age nor size is given all files which match a pattern in matches will be removed.

NOTE: The regex patterns in this function are used in re.match(), so there is an implicit "beginning of string" anchor (^) in the regex and it is unanchored at the other end unless explicitly entered ($).

name: The directory tree that should be tidied
age: Maximum age in days after which files are considered for removal
matches: List of regular expressions to restrict what gets removed. Default: ['.*']
rmdirs: Whether or not it's allowed to remove directories
size: Maximum allowed file size. Files greater or equal to this size are removed. Doesn't apply to directories or symbolic links
exclude: List of regular expressions to filter the matches parameter and better control what gets removed.

New in version 3005.
full_path_match: Match the matches and exclude regex patterns against the entire file path instead of just the file or directory name. Default: False

New in version 3005.
followlinks: This module will not descend into subdirectories which are pointed to by symbolic links. If you wish to force it to do so, you may give this option the value True. Default: False

New in version 3005.
time_comparison: Default: atime. Options: atime/mtime/ctime. This value is used to set the type of time comparison made using age. The default is to compare access times (atime) or the last time the file was read. A comparison by modification time (mtime) uses the last time the contents of the file was changed. The ctime parameter is the last time the contents, owner, or permissions of the file were changed.

New in version 3005.
age_size_logical_operator: This parameter can change the default operation (OR) to an AND operation to evaluate age and size. In that scenario, a file that is too large but is not old enough will NOT get tidied. A file will need to fulfill BOTH conditions in order to be tidied. Accepts OR or AND.

New in version 3006.0.
age_size_only: This parameter can trigger the reduction of age and size conditions which need to be satisfied down to ONLY age or ONLY size. By default, this parameter is None and both conditions will be evaluated using the logical operator defined in age_size_logical_operator. The parameter can be set to age or size in order to restrict evaluation down to that specific condition. Path matching and exclusions still apply.

New in version 3006.0.
rmlinks: Whether or not it's allowed to remove symbolic links

New in version 3006.0.

cleanup:
  file.tidied:
    - name: /tmp/salt_test
    - rmdirs: True
    - matches:
      - foo
      - b.*r

salt.states.file.touch(name, atime=None, mtime=None, makedirs=False)¶

Replicate the 'nix "touch" command to create a new empty file or update the atime and mtime of an existing file.

Note that if you just want to create a file and don't care about atime or mtime, you should use file.managed instead, as it is more feature-complete. (Just leave out the source/template/contents arguments, and it will just create the file and/or check its permissions, without messing with contents)

name: name of the file
atime: atime of the file
mtime: mtime of the file
makedirs: whether we should create the parent directory/directories in order to touch the file

Usage:

/var/log/httpd/logrotate.empty:
  file.touch

New in version 0.9.5.

salt.states.file.uncomment(name, regex, char='#', backup='.bak')¶

Uncomment specified commented lines in a file

name

The full path to the file to be edited

regex

A regular expression used to find the lines that are to be uncommented. This regex should not include the comment character. A leading ^ character will be stripped for convenience (for easily switching between comment() and uncomment()). The regex will be searched for from the beginning of the line, ignoring leading spaces (we prepend '^[ t]*')

char

The character to remove in order to uncomment a line

backup

The file will be backed up before edit with this file extension;

Warning

This backup will be overwritten each time sed / comment / uncomment is called. Meaning the backup will only be useful after the first invocation.

Set to False/None to not keep a backup.

Usage:

/etc/adduser.conf:
  file.uncomment:
    - regex: EXTRA_GROUPS

New in version 0.9.5.
