Users role

Role to manage users on a system.

Role configuration

• users_create_per_user_group (default: true) - when creating users, also create a group with the same username and make that the user's primary group.
• users_group (default: users) - if users_create_per_user_group is not set, then this is the primary group for all created users.
• users_default_shell (default: /bin/bash) - the default shell if none is specified for the user.
• users_create_homedirs (default: true) - create home directories for new users. Set this to false is you manage home directories separately.

Creating users

Add a users variable containing the list of users to add. A good place to put this is in group_vars/all or group_vars/groupname if you only want the users to be on certain machines.

The following attributes are required for each user:

• username - The user's username.
• name - The full name of the user (gecos field)
• uid - The numeric user id for the user. This is required for uid consistency across systems.
• password - If a hash is provided then that will be used, but otherwise the account will be locked
• groups - a list of supplementary groups for the user.
• ssh-key - This should be a list of ssh keys for the user. Each ssh key should be included directly and should have no newlines.

In addition, the following items are optional for each user:

• shell - The user's shell. This defaults to /bin/bash. The default is configurable using the users_default_shell variable if you want to give all users the same shell, but it is different than /bin/bash.
• gid - You can specify this option for a user if you do not want their primary group id to be the same as their user id.

Example:

---
users:
  - username: foo
    name: Foo Barrington
    groups: ['wheel','systemd-journal']
    uid: 1001
    ssh_key:
      - "ssh-rsa AAAAA.... foo@machine"
      - "ssh-rsa AAAAB.... foo2@machine"
users_deleted:
  - username: bar
    name: Bar User
    uid: 1002

Deleting users

The users_deleted variable contains a list of users who should no longer be in the system, and these will be removed on the next ansible run. The format is the same as for users to add, but the only required field is username. However, it is recommended that you also keep the uid field for reference so that numeric user ids are not accidentally reused.
