Meta tasks are a special kind of task which can influence Ansible internal execution or state. Prior to Ansible 2.0, the only meta option available was flush_handlers
. As of 2.2, there are five meta tasks which can be used. Meta tasks can be used anywhere within your playbook.
parameter | required | default | choices | comments |
---|---|---|---|---|
free_form | yes |
|
This module takes a free form command, as a string. There's 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 2.0) forces the reload of the inventory, which in the case of dynamic inventory scripts means they will be re-executed. This is mainly useful when additional hosts are created and users wish to use them instead of using the `add_host` module.noop (added in 2.0) This literally does 'nothing'. It is mainly used internally and not recommended for general use.clear_facts (added in 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 2.1) clears the failed state (if any) from hosts specified in the play's list of hosts.end_play (added in 2.2) causes the play to end without failing the host. |
# force all notified handlers to run at this point, not waiting for normal sync points - template: src=new.j2 dest=/etc/config.txt notify: myhandler - meta: flush_handlers # reload inventory, useful with dynamic inventories when play makes changes to the existing hosts - cloud_guest: name=newhost state=present # this is fake module - meta: refresh_inventory # clear gathered facts from all currently targeted hosts - meta: clear_facts # bring host back to play after failure - copy: src=file dest=/etc/file remote_user: imightnothavepermission - meta: clear_host_errors
Note
meta is not really a module nor action_plugin as such it cannot be overwritten.
