These are the keywords available on common playbook objects. Keywords are one of several sources for configuring Ansible behavior. See Controlling how Ansible behaves: precedence rules for details on the relative precedence of each source.
Note
Please note:
version_added information at this timeany_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. Implemented by the become plugin. See Become Plugins.
become_exe Path to the executable used to elevate privileges. Implemented by the become plugin. See Become Plugins.
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 Validating tasks: check mode and diff mode.
collections List of collection namespaces to search for modules, plugins, and roles. See Using collections in a Playbook
Note
Tasks within a role do not inherit the value of collections from the play. To have a role search a list of collections, use the collections keyword in meta/main.yml within a role.
connection Allows you to change the connection plugin used for tasks to execute on the target. See Using connection plugins.
debugger Enable debugging tasks based on state of the task result. See Debugging tasks.
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. This can ONLY be used with modules. This isn’t supported for any other type of plugins nor Ansible itself nor its configuration, it just sets the variables for the code responsible for executing the task. This is not a recommended way to pass in confidential data.
fact_path Set the fact path option for the fact gathering plugin controlled by gather_facts.
force_handlers Will force notified handler execution for hosts even if they failed during the play. Will not trigger if the play itself fails.
gather_facts A boolean that controls if the play will automatically run the ‘setup’ task to gather facts for the hosts.
gather_subset Allows you to pass subset options to the fact gathering plugin controlled by gather_facts.
gather_timeout Allows you to set the timeout for the fact gathering plugin controlled by gather_facts.
handlers A section with tasks that are treated as handlers, these won’t get executed normally, only when notified after each section of tasks is complete. A handler’s listen field is not templatable.
hosts A list of groups, hosts or host pattern that translates into a list of hosts that are the play’s target.
ignore_errors Boolean that allows you to ignore task failures and continue with play. It does not affect connection errors.
ignore_unreachable Boolean that allows you to ignore task failures due to an unreachable host and continue with the play. This does not affect other task errors (see ignore_errors) but is useful for groups of volatile/ephemeral hosts.
max_fail_percentage can be used to abort the run after a given percentage of hosts in the current batch has failed. This only wokrs on linear or linear derived strategies.
module_defaults Specifies default parameter values for modules.
name Identifier. Can be used for documentation, or in tasks/handlers.
no_log Boolean that controls information disclosure.
order Controls the sorting of hosts as they are used for executing the play. Possible values are inventory (default), sorted, reverse_sorted, reverse_inventory and shuffle.
port Used to override the default port used in a connection.
post_tasks A list of tasks to execute after the tasks section.
pre_tasks A list of tasks to execute before roles.
remote_user User used to log into the target via the connection plugin.
roles List of roles to be imported into the play
run_once Boolean that will bypass the host loop, forcing the task to attempt to execute on the first host available and afterwards apply any results and facts to all active hosts in the same batch.
serial Explicitly define how Ansible batches the execution of the current play on the play’s target
See also
strategy Allows you to choose the connection plugin to use for the play.
Tags applied to the task or included tasks, this allows selecting subsets of tasks from the command line.
tasks Main list of tasks to execute in the play, they run after roles and before post_tasks.
throttle Limit number of concurrent task runs on task, block and playbook level. This is independent of the forks and serial settings, but cannot be set higher than those limits. For example, if forks is set to 10 and the throttle is set to 15, at most 10 hosts will be operated on in parallel.
timeout Time limit for task to execute in, if exceeded Ansible will interrupt and fail the task.

vars_files List of files that contain vars to include in the play.
vars_prompt list of variables to prompt for.
