Minion data cache plugin for Etcd key/value data store.
.. versionadded:: develop
It is up to the system administrator to set up and configure the Etcd
infrastructure. All is needed for this plugin is a working Etcd agent
with a read-write access to the key-value store.
The related documentation can be found in the `Etcd documentation`_.
To enable this cache plugin, the master will need the python client for
Etcd installed. This can be easily installed with pip:
.. code-block: bash
pip install python-etcd
Optionally, depending on the Etcd agent configuration, the following values
could be set in the master config. These are the defaults:
.. code-block:: yaml
etcd.host: 127.0.0.1
etcd.port: 2379
etcd.protocol: http
etcd.allow_reconnect: True
etcd.allow_redirect: False
etcd.srv_domain: None
etcd.read_timeout: 60
etcd.username: None
etcd.password: None
etcd.cert: None
etcd.ca_cert: None
Related docs could be found in the `python-etcd documentation`_.
To use the etcd as a minion data cache backend, set the master ``cache`` config
value to ``etcd``:
.. code-block:: yaml
cache: etcd
.. _`Etcd documentation`: https://github.com/coreos/etcd
.. _`python-etcd documentation`: http://python-etcd.readthedocs.io/en/latest/
