‘‘‘ Management of user groups ========================= The group module is used to create and manage unix group settings, groups can be either present or absent: .. code-block:: yaml cheese: group.present: - gid: 7648 - system: True - addusers: - user1 - users2 - delusers: - foo cheese: group.present: - gid: 7648 - system: True - members: - foo - bar - user1 - user2 ‘‘‘
def present(name,
gid=None,
system=False,
addusers=None,
delusers=None,
members=None):
‘‘‘
Ensure that a group is present
name
The name of the group to manage
gid
The group id to assign to the named group; if left empty, then the next
available group id will be assigned
system
Whether or not the named group is a system group. This is essentially
the ‘-r‘ option of ‘groupadd‘.
addusers
List of additional users to be added as a group members.
delusers
Ensure these user are removed from the group membership.
members
Replace existing group members with a list of new members.
Note: Options ‘members‘ and ‘addusers/delusers‘ are mutually exclusive and
can not be used together.
