ansible.builtin.meta – Execute Ansible ‘actions’

Note

This module is part of ansible-base and included in all Ansible installations. In most cases, you can use the short module name meta even without specifying the collections: keyword. Despite that, we recommend you use the FQCN for easy linking to the module documentation and to avoid conflicting with other collections that may have the same module name.

New in version 1.2: of ansible.builtin

Synopsis

  • Meta tasks are a special kind of task which can influence Ansible internal execution or state.

  • Meta tasks can be used anywhere within your playbook.

  • This module is also supported for Windows targets.

Parameters

Parameter Choices/Defaults Comments
free_form
string / required
    Choices:
  • clear_facts
  • clear_host_errors
  • end_host
  • end_play
  • flush_handlers
  • noop
  • refresh_inventory
  • reset_connection
  • end_batch
This module takes a free form command, as a string. There is not an actual option named "free form". See the examples!
flush_handlers makes Ansible run any handler tasks which have thus far been notified. Ansible inserts these tasks internally at certain points to implicitly trigger handler runs (after pre/post tasks, the final role execution, and the main tasks section of your plays).
refresh_inventory (added in Ansible 2.0) forces the reload of the inventory, which in the case of dynamic inventory scripts means they will be re-executed. If the dynamic inventory script is using a cache, Ansible cannot know this and has no way of refreshing it (you can disable the cache or, if available for your specific inventory datasource (e.g. aws), you can use the an inventory plugin instead of an inventory script). This is mainly useful when additional hosts are created and users wish to use them instead of using the ansible.builtin.add_host module.
noop (added in Ansible 2.0) This literally does 'nothing'. It is mainly used internally and not recommended for general use.
clear_facts (added in Ansible 2.1) causes the gathered facts for the hosts specified in the play's list of hosts to be cleared, including the fact cache.
clear_host_errors (added in Ansible 2.1) clears the failed state (if any) from hosts specified in the play's list of hosts.
end_play (added in Ansible 2.2) causes the play to end without failing the host(s). Note that this affects all hosts.
reset_connection (added in Ansible 2.3) interrupts a persistent connection (i.e. ssh + control persist)
end_host (added in Ansible 2.8) is a per-host variation of end_play. Causes the play to end for the current host without failing it.
end_batch (added in Ansible 2.12) causes the current batch (see serial) to end without failing the host(s). Note that with serial=0 or undefined this behaves the same as end_play.

Notes

Note

  • meta is not really a module nor action_plugin as such it cannot be overwritten.

  • clear_facts will remove the persistent facts from ansible.builtin.set_fact using cacheable=True, but not the current host variable it creates for the current run.

  • Looping on meta tasks is not supported.

  • Skipping meta tasks with tags is not supported before Ansible 2.11.

  • This module is also supported for Windows targets.

  meta: flush_handlers

# Example showing how to refresh inventory during play
- name: Reload inventory, useful with dynamic inventories when play makes changes to the existing hosts
  cloud_guest:            # this is fake module
    name: newhost
    state: present

- name: Refresh inventory to ensure new instances exist in inventory
  meta: refresh_inventory

# Example showing how to clear all existing facts of targetted hosts
- name: Clear gathered facts from all currently targeted hosts
  meta: clear_facts

# Example showing how to continue using a failed target
- name: Bring host back to play after failure
  copy:
    src: file
    dest: /etc/file
  remote_user: imightnothavepermission

- meta: clear_host_errors

# Example showing how to reset an existing connection
- user:
    name: '{{ ansible_user }}'
    groups: input

- name: Reset ssh connection to allow user changes to affect 'current login user'
  meta: reset_connection

# Example showing how to end the play for specific targets
- name: End the play for hosts that run CentOS 6
  meta: end_host
  when:
  - ansible_distribution == 'CentOS'
  - ansible_distribution_major_version == '6'
