Strategy Plugins
----------------

Strategy plugins control the flow of play execution, they handle task and host scheduleing.


Enabling Cache Plugins
++++++++++++++++++++++

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 :doc:`linear <strategy/linear>` plugin, you can change this default via :doc:`configuration <../config>`:

.. code-block:: shell

    export ANSIBLE_STRATEGY=free

or in the `ansible.cfg` file:

.. code-block:: ini

    [defaults]
    strategy=linear

Or you can just speicfy the plugin in the play via the :ref:`strategy` keyword::

  - 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 specific documents and examples.
