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_addedinformation at this time - Some keywords set defaults for the objects inside of them rather than for the objects themselves
 
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
See also
 connection- 
    
Allows you to change the connection plugin used for tasks to execute on the target.
See also
using_connection

 environment- A dictionary that gets converted into environment vars to be provided for the task upon execution.
