Ansible Role

Posted on | Edited on | In

To reuse role in a playbook, there are 3 options:

  • roles: at play level, statically, executed before tasks.
  • include_role: at task level, dynamically, parsed and executed at where it is defined.
  • import_role: at task level, statically, parsed before the calling play execution and if no syntax error executed at where it is defined.

Regarding statically and dynamically above, there is explanation.

  tasks:
    # Dynamiaclly load, parse and run role in playbook where it is defined.
    - name: Include role
      include_role:
        name: <role name>

    # Statically load role, the same as 'roles' clause that will parse the
    # imported role before playbook runs, it will fail the playbook if there is
    # any syntax error.
    - name: Import role
      import_role:
        name: <role name>
