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
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)¶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
New in version 2015.5.0.
Override the delimiter used to separate nested levels of a data structure.
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
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.
Pass as True
to exclude matches from the minion configuration file
Pass as True
to exclude matches from the grains
Pass as True
to exclude matches from the pillar data
Pass as True
to exclude matches from the master configuration file
Shorthand to omit all of the above and return matches only from the "sane defaults".
New in version 3000.
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
