Strategy Plugins ¶

Strategy plugins control the flow of play execution by handling task and host scheduling.

Enabling Strategy Plugins ¶

Strategy plugins shipped with Ansible are enabled by default. You can enable a custom strategy plugin by putting it in one of the lookup directory sources configured in ansible.cfg.

Only one strategy plugin can be used in a play, but you can use different ones for each play in a playbook or ansible run. The default is the linear plugin. You can change this default in Ansible configuration using an environment variable:

export ANSIBLE_STRATEGY=free

or in the ansible.cfg file:

[defaults]
strategy=linear

You can also specify the strategy plugin in the play via the strategy keyword in a play:

- hosts: all
  strategy: debug
  tasks:
    - copy: src=myhosts dest=/etc/hosts
      notify: restart_tomcat

    - package: name=tomcat state=present

  handlers:
    - name: restart_tomcat
      service: name=tomcat state=restarted

Plugin List ¶

You can use ansible-doc -t strategy -l to see the list of available plugins. Use ansible-doc -t strategy <plugin name> to see plugin-specific specific documentation and examples.
