async: Run a task asyncronouslly if the C(action) supports this.
become: Boolean that controls if privilege escalation is used or not on :term:`Task` execution.
become_flags: A string of flag(s) to pass to the privilege escalation program when :term:`become` is True.

check_mode: "A boolean that controls if a task is executed in 'check' mode"
connection: Allows you to change the connection plugin used for tasks to execute on the target.
delay: Number of seconds to delay between retries, this setting is only used in combination with :term:`until`.
delegate_facts: Boolean that allows you to apply facts to delegated host instead of inventory_hostname.
delegate_to: Host to execute task instead of the target (inventory_hostname), connection vars from the delegated host will also be used for the task.
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.
fact_path: Set the fact path option for the fact gathering plugin controlled by :term:`gather_facts`.
failed_when: "Conditional expression that overrides the task's normal 'failed' status."
force_handlers: Will force notified handler execution for hosts even if they failed during the play, it 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 :term:`gather_facts`.
gather_timeout: Allows you to set the timeout for the fact gathering plugin controlled by :term:`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."
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.
loop: "Takes a list for the task to iterate over, saving each list element into the ``item`` variable (configurable via loop_control)"
loop_control: "Several keys here allow you to modify/set loop behaviour in a task see http://docs.ansible.com/ansible/latest/playbooks_loops.html#loop-control for details."
max_fail_percentage: can be used to abort the run after a given percentage of hosts in the current batch has failed.
name: "It's a name, works mostly for documentation, in the case of tasks/handlers it can be an identifier."
no_log: Boolean that controls information disclosure.
notify: "list of handlers to notify when the task returns a 'changed=True' status."
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.
poll: Sets the polling interval in seconds for async tasks (default 10s).
port: Used to override the default port used in a connection.
post_tasks: A list of tasks to execute after the :term:`tasks` section.
pre_tasks: A list of tasks to execute before :term:`roles`.
remote_user: User used to log into the target via the connection plugin. AKA login user.
register: Name of variable that will contain task status and module return data.
rescue: List of tasks in a :term:`block` that run if there is a task error in the main :term:`block` list.
retries: "Number of retries before giving up in a :term:`until` loop. This setting is only used in combination with :term:`until`."
roles: List of roles to be imported into the play
run_once: Boolean that will bypass the host loop, forcing the task to execute on the first host available and will also apply any facts to all active hosts.
serial: Defines the 'batch' of hosts to execute the current play until the end.
strategy: Allows you to choose the connection plugin to use for the play.
tags: 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 :term:`roles` and before :term:`post_tasks`.
until: "This keyword implies a ':term:`retries` loop' that will go on until the condition supplied here is met or we hit the :term:`retries` limit."
vars: Dictionary/map of variables
vars_files: List of files that contain vars to include in the play.
vars_prompt: list of variables to prompt for.
vault_password: Secret used to decrypt vaulted files or variables.
when: Conditional expression, determines if an iteration of a task is run or not.
