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

|
Enabling Strategy 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 in Ansible :doc:`configuration <../config>` using an environment variable:
|
|
|
|
.. code-block:: shell
|
|
|
|
export ANSIBLE_STRATEGY=free
|
|
|
|
or in the `ansible.cfg` file:
|
|
|
|
.. code-block:: ini
|
|
|
|
[defaults]
|
|
strategy=linear
|
|
|
|
You can also specify the strategy 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
|
|
|
