* Due to the takeover of freenode we're moving to a different irc network. * Our channels updated to point at the same channel name on libera.chat * Some links went to webchat.freenode.net. At this time, libera.chat doesn't point you to an official webchat client so I changed these to https://libera.chat. (kiwi irc does work with libera.chat so that could be another option). * In general, I used the name irc.libera.net for link names and https://libera.chat for link targets. This is because the irc service is hosted on irc.libera.chat but the project web server is hosted on libera.chat. (This appears to also be true for freenode but we were using http://irc.freenode.net which doesn't seem to work. Oops). * Removed http://irc.freenode.net from the linkcheck exceptions. linkcheck was actually correct to flag that as invalid (should have been http://frenode.net instead). * Looks like hte important people in #yaml are now in libera.chat * Link to where contributors should get help Add a link target and then link to where contributors should get support for developing groups of modules. * Update docs/docsite/rst/dev_guide/developing_modules_in_groups.rst Co-authored-by: Felix Fontein <felix@fontein.de> Co-authored-by: John R Barker <john@johnrbarker.com> Co-authored-by: Felix Fontein <felix@fontein.de>

Enabling strategy plugins
|
|
-------------------------
|
|
|
|
All 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 :ref:`ansible.cfg <ansible_configuration_settings>`.

Using 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 :ref:`linear <linear_strategy>` plugin. You can change this default in Ansible :ref:`configuration <ansible_configuration_settings>` 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 <playbook_keywords>` 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.
