Minion data cache plugin for Consul key/value data store.
.. versionadded:: 2016.11.2
:depends: python-consul >= 0.2.0
It is up to the system administrator to set up and configure the Consul
infrastructure. All is needed for this plugin is a working Consul agent
with a read-write access to the key-value store.
The related documentation can be found in the `Consul documentation`_.
To enable this cache plugin, the master will need the python client for
Consul installed. This can be easily installed with pip:
.. code-block: bash
pip install python-consul
Optionally, depending on the Consul agent configuration, the following values
could be set in the master config. These are the defaults:
.. code-block:: yaml
consul.host: 127.0.0.1
consul.port: 8500
consul.token: None
consul.scheme: http
consul.consistency: default
consul.dc: dc1
consul.verify: True
Related docs could be found in the `python-consul documentation`_.
To use the consul as a minion data cache backend, set the master ``cache`` config
value to ``consul``:
.. code-block:: yaml
cache: consul
.. _`Consul documentation`: https://www.consul.io/docs/index.html
.. _`python-consul documentation`: https://python-consul.readthedocs.io/en/latest/#consul
