# 2. Keywords¶

Keyword

Description

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.

action

The 'action' to execute for a task, it normally translates into a C(module) or action plugin.

args

A secondary way to add arguments into a task. Takes a dictionary in which keys map to options and values.

always

List of tasks, in a block, that execute no matter if there is an error in the block or not.

any_errors_fatal

Force any un-handled task errors on any host to propagate to all hosts and end the play.

async

Run a task asynchronously if the C(action) supports this; value is maximum runtime in seconds.

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.

block

List of tasks in a block.

changed_when

Conditional expression that overrides the task's normal 'changed' status.

check_mode

A boolean that controls if a task is executed in 'check' mode check_mode_dry

connection

Allows you to change the connection plugin used for tasks to execute on the target. using_connection

debugger

Enable debugging tasks based on state of the task result. See playbook_debugger

delay

Number of seconds to delay between retries. This setting is only used in combination with until.

delegate_facts

Boolean that allows you to apply facts to a 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. 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.

fact_path

Set the fact path option for the fact gathering plugin controlled by 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. 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.

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 eys here allow you to modify/set loop behaviour in a task. loop_control

max_fail_percentage

can be used to abort the run after a given percentage of hosts in the current batch has failed.

module_defaults

Specifies default parameter values for modules.

name

Identifier. Can be used for documentation, in or tasks/handlers.

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

pre_tasks

A list of tasks to execute before roles.

remote_user

register

Name of variable that will contain task status and module return data.

rescue

List of tasks in a block that run if there is a task error in the main block list.

retries

Number of retries before giving up in a until loop. This setting is only used in combination with until.

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 rolling_update_batch_size

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 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.

until

This keyword implies a 'retries loop' that will go on until the condition supplied here is met or we hit the 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.

when

Conditional expression, determines if an iteration of a task is run or not.
