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
Role
Block
Task

Play

accelerate: DEPRECATED, set to True to use accelerate connection plugin.
accelerate_ipv6: DEPRECATED, set to True to force accelerate plugin to use ipv6 for its connection.
accelerate_port: DEPRECATED, set to override default port use for accelerate connection.
always_run: DEPRECATED, forces a task to run even in check mode. Use check_mode directive instead.
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.
check_mode: A boolean that controls if a task is executed in ‘check’ mode

using_connection
diff: Toggle to make tasks return ‘diff’ information or not.
environment: A dictionary that gets converted into environment vars to be provided for the task upon execution.
