Cache Plugins
|
|
-------------
|
|
|
|
Cache plugin implement a backend caching mechanism that allows Ansible to store gathered facts or inventory source data
|
|
without the performance hit of retrieving them from source.
|
|
|
|
The default cache plugin is the :doc:`memory <cache/memory>` plugin, which only caches the data for the current execution of Ansible. Other plugins with persistent storage are available to allow caching the data across runs.

|
Enabling Cache Plugins
|
|
++++++++++++++++++++++
|
|
|
|
Only one cache plugin can be active at a time.
|
|
You can enable a cache plugin in the Ansible configuration, either via environment variable:
|
|
|
|
.. code-block:: shell
|
|
|
|
export ANSIBLE_CACHE_PLUGIN=jsonfile
|
|
|
|
or in the ``ansible.cfg`` file:
|
|
|
|
.. code-block:: ini
|
|
|
|
[defaults]
|
|
fact_caching=redis
|
|
|
|
You will also need to configure other settings specific to each plugin. Consult the individual plugin documentation
|
|
or the Ansible :doc:`configuration <../config>` for more details.
|
|
|
|
A custom cache plugin is enabled by dropping it into a ``cache_plugins`` directory adjacent to your play, inside a role, or by putting it in one of the directory sources configured in :doc:`ansible.cfg <../config>`.
