salt.modules.config#

Return config information

salt.modules.config.backup_mode(backup='')#

Return the backup mode

CLI Example:

salt '*' config.backup_mode

salt.modules.config.dot_vals(value)#

Pass in a configuration value that should be preceded by the module name and a dot, this will return a list of all read key/value pairs

CLI Example:

salt '*' config.dot_vals host

salt.modules.config.gather_bootstrap_script(bootstrap=None)#

Download the salt-bootstrap script, and return its location

bootstrap: URL of alternate bootstrap script

CLI Example:

salt '*' config.gather_bootstrap_script

salt.modules.config.get(key, default='', delimiter=':', merge=None, omit_opts=False, omit_pillar=False, omit_master=False, omit_grains=False)#

New in version 0.14.0.

Attempt to retrieve the named value from the minion config file, pillar, grains or the master config. If the named value is not available, return the value specified by the default argument. If this argument is not specified, default falls back to an empty string.

Values can also be retrieved from nested dictionaries. Assume the below data structure:

{'pkg': {'apache': 'httpd'}}

To retrieve the value associated with the apache key, in the sub-dictionary corresponding to the pkg key, the following command can be used:

salt myminion config.get pkg:apache

The : (colon) is used to represent a nested dictionary level.

Changed in version 2015.5.0: The delimiter argument was added, to allow delimiters other than : to be used.

This function traverses these data stores in this order, returning the first match found:

Minion configuration
Minion's grains
Minion's pillar data
Master configuration (requires pillar_opts to be set to True in Minion config file in order to work)

This means that if there is a value that is going to be the same for the majority of minions, it can be configured in the Master config file, and then overridden using the grains, pillar, or Minion config file.

Adding config options to the Master or Minion configuration file is easy:

my-config-option: value
cafe-menu:
  - egg and bacon
  - egg sausage and bacon
  - egg and spam
  - egg bacon and spam
  - egg bacon sausage and spam
  - spam bacon sausage and spam
  - spam egg spam spam bacon and spam
  - spam sausage spam spam bacon spam tomato and spam

Note

Minion configuration options built into Salt (like those defined here) will always be defined in the Minion configuration and thus cannot be overridden by grains or pillar data. However, additional (user-defined) configuration options (as in the above example) will not be in the Minion configuration by default and thus can be overridden using grains/pillar data by leaving the option out of the minion config file.

Arguments

delimiter

New in version 2015.5.0.

Override the delimiter used to separate nested levels of a data structure.

merge

New in version 2015.5.0.

If passed, this parameter will change the behavior of the function so that, instead of traversing each data store above in order and returning the first match, the data stores are first merged together and then searched. The pillar data is merged into the master config data, then the grains are merged, followed by the Minion config data. The resulting data structure is then searched for a match. This allows for configurations to be more flexible.

Note

The merging described above does not mean that grain data will end up in the Minion's pillar data, or pillar data will end up in the master config data, etc. The data is just combined for the purposes of searching an amalgam of the different data stores.

The supported merge strategies are as follows:

recurse - If a key exists in both dictionaries, and the new value is not a dictionary, it is replaced. Otherwise, the sub-dictionaries are merged together into a single dictionary, recursively on down, following the same criteria. For example:

>>> dict1 = {'foo': {'bar': 1, 'qux': True},
             'hosts': ['a', 'b', 'c'],
             'only_x': None}
>>> dict2 = {'foo': {'baz': 2, 'qux': False},
             'hosts': ['d', 'e', 'f'],
             'only_y': None}
>>> merged
{'foo': {'bar': 1, 'baz': 2, 'qux': False},
 'hosts': ['d', 'e', 'f'],
 'only_dict1': None,
 'only_dict2': None}

overwrite - If a key exists in the top level of both dictionaries, the new value completely overwrites the old. For example:

>>> dict1 = {'foo': {'bar': 1, 'qux': True},
             'hosts': ['a', 'b', 'c'],
             'only_x': None}
>>> dict2 = {'foo': {'baz': 2, 'qux': False},
             'hosts': ['d', 'e', 'f'],
             'only_y': None}
>>> merged
{'foo': {'baz': 2, 'qux': False},
 'hosts': ['d', 'e', 'f'],
 'only_dict1': None,
 'only_dict2': None}

CLI Example:

salt '*' config.get pkg:apache
salt '*' config.get lxc.container_profile:centos merge=recurse

salt.modules.config.items()#

Return the complete config from the currently running minion process. This includes defaults for values not set in the config file.

CLI Example:

salt '*' config.items

salt.modules.config.manage_mode(mode)#

Return a mode value, normalized to a string

CLI Example:

salt '*' config.manage_mode

salt.modules.config.merge(value, default='', omit_opts=False, omit_master=False, omit_pillar=False)#

Retrieves an option based on key, merging all matches.

Same as option() except that it merges all matches, rather than taking the first match.

CLI Example:

salt '*' config.merge schedule

salt.modules.config.option(value, default=None, omit_opts=False, omit_grains=False, omit_pillar=False, omit_master=False, omit_all=False, wildcard=False)#

Returns the setting for the specified config value. The priority for matches is the same as in config.get, only this function does not recurse into nested data structures. Another difference between this function and config.get is that it comes with a set of "sane defaults". To view these, you can run the following command:

salt '*' config.option '*' omit_all=True wildcard=True

default

The default value if no match is found. If not specified, then the fallback default will be an empty string, unless wildcard=True, in which case the return will be an empty dictionary.

omit_optsFalse

Pass as True to exclude matches from the minion configuration file

omit_grainsFalse

Pass as True to exclude matches from the grains

omit_pillarFalse

Pass as True to exclude matches from the pillar data

omit_masterFalse

Pass as True to exclude matches from the master configuration file

omit_allTrue

Shorthand to omit all of the above and return matches only from the "sane defaults".

New in version 3000.

wildcardFalse

If used, this will perform pattern matching on keys. Note that this will also significantly change the return data. Instead of only a value being returned, a dictionary mapping the matched keys to their values is returned. For example, using wildcard=True with a key of 'foo.ba* could return a dictionary like so:

{'foo.bar': True, 'foo.baz': False}

New in version 3000.

CLI Example:

salt '*' config.option redis.host

salt.modules.config.valid_fileproto(uri)#

Returns a boolean value based on whether or not the URI passed has a valid remote file protocol designation

CLI Example:

salt '*' config.valid_fileproto salt://path/to/file
