Description

This role provides a very basic users management, for simple clusters.

Instructions

Create file inventory/group_vars/all/addons/users_basic.yml with the following content:

users_basic:

  users:
    - name: johnnykeats
      uid: 1078
      gid: 1078
      home: /home
      shell: /bin/bash
      comment: dream all the day # optional
      password: $6$M3crarMVoUV3rALd$ZTre2CIyss7zOb4lkLoG23As9OAkYPw2BM88Y1F43n8CCyV5XWwAYEwBOrS8bcCBIMjIPdJG.ndOfzWyAVR4j0

Then edit this file according to your needs, and play this role on all hosts with users, including slurmctld server if using slurm.

Available arguments for each user are:

• name
• uid
• gid
• password
• state
• groups (optional)
• create_home (optional)
• update_password (optional)
• shell (optional)
• home (optional)
• generate_ssh_key (optional)
• ssh_key_bits (optional)
• ssh_key_file (optional)
• remove (optional)
• comment (optional)

To ensure a user is not on a system, set state to "absent". To also remove its home, set remove to "yes".

It is also possible to add ssh public keys for users. The following parameters are available for each user:

• ssh_key
• ssh_key_exclusive

To generate an sha512 password, use the following command (python >3.3):

python -c 'import crypt,getpass; print(crypt.crypt(getpass.getpass(), crypt.mksalt(crypt.METHOD_SHA512)))'

Or (python 2):

python -c "import crypt,random,string; print crypt.crypt(raw_input('clear-text password: '), '\$6\$' + ''.join([random.choice(string.ascii_letters + string.digits) for _ in range(16)]))"
