Playbook Keywords

These are the keywords available on common playbook objects.

Note

Please note:

  • Aliases for the directives are not reflected here, nor are mutable one. For example, action in task can be substituted by the name of any Ansible module.
  • The keywords do not have version_added information at this time
  • Some keywords set defaults for the objects inside of them rather than for the objects themselves

Play

any_errors_fatal
Force any un-handled task errors on any host to propagate to all hosts and end the play.
become
Boolean that controls if privilege escalation is used or not on Task execution.
become_flags
A string of flag(s) to pass to the privilege escalation program when become is True.
become_method
Which method of privilege escalation to use (such as sudo or su).
become_user
User that you ‘become’ after using privilege escalation. The remote/login user must have permissions to become this user.
