salt.states.grains

Manage grains on the minion

This state allows for grains to be set. Grains set or altered this way are stored in the 'grains' file on the minions, by default at: /etc/salt/grains

Note: This does NOT override any grains set in the minion file.

salt.states.grains.absent(name, destructive=False, delimiter=':', force=False)

New in version 2014.7.0.

Delete a grain from the grains config file

name
The grain name
Parameters:
  • destructive -- If destructive is True, delete the entire grain. If destructive is False, set the grain's value to None. Defaults to False.
  • force --

    If force is True, the existing grain will be overwritten regardless of its existing or provided value type. Defaults to False

    New in version Boron.

  • delimiter --

    A delimiter different from the default can be provided.

    New in version Boron.

Changed in version Boron.

This state now support nested grains and complex values. It is also more conservative: if a grain has a value that is a list or a dict, it will not be removed unless the force parameter is True.

grain_name:
  grains.absent: []
salt.states.grains.append(name, value, convert=False, delimiter=':')

New in version 2014.7.0.

Append a value to a list in the grains config file

name
The grain name
value
The value to append
Parameters:
  • convert -- If convert is True, convert non-list contents into a list. If convert is False and the grain contains non-list contents, an error is given. Defaults to False.
  • delimiter --

    A delimiter different from the default can be provided.

    New in version Boron.

grain_name:
  grains.append:
    - value: to_be_appended
salt.states.grains.list_absent(name, value, delimiter=':')

Delete a value from a grain formed as a list.

New in version 2014.1.0.

name
The grain name.
value
The value to delete from the grain list.
Parameters:delimiter --

A delimiter different from the default : can be provided.

New in version Boron.

The grain should be list type

roles:
  grains.list_absent:
    - value: db

For multiple grains, the syntax looks like:

roles:
  grains.list_absent:
    - value:
      - web
      - dev
salt.states.grains.list_present(name, value, delimiter=':')

New in version 2014.1.0.

Ensure the value is present in the list type grain.

name
The grain name.
value
The value is present in the list type grain.
Parameters:delimiter --

A delimiter different from the default : can be provided.

New in version Boron.

The grain should be list type

roles:
  grains.list_present:
    - value: web

For multiple grains, the syntax looks like:

roles:
  grains.list_present:
    - value:
      - web
      - dev
salt.states.grains.present(name, value, delimiter=':', force=False)

Ensure that a grain is set

Changed in version Boron.

name
The grain name
value
The value to set on the grain
Parameters:
  • force --

    If force is True, the existing grain will be overwritten regardless of its existing or provided value type. Defaults to False

    New in version Boron.

  • delimiter --

    A delimiter different from the default can be provided.

    New in version Boron.

It is now capable to set a grain to a complex value (ie. lists and dicts) and supports nested grains as well.

If the grain does not yet exist, a new grain is set to the given value. For a nested grain, the necessary keys are created if they don't exist. If a given key is an existing value, it will be converted, but an existing value different from the given key will fail the state.

If the grain with the given name exists, its value is updated to the new value unless its existing or provided value is complex (list or dict). Use force: True to overwrite.
