etcd Database Module
:maintainer: SaltStack
:maturity: New
:depends: python-etcd
:platform: all
.. versionadded:: 2015.5.0
This module allows access to the etcd database using an ``sdb://`` URI. This
package is located at ``https://pypi.python.org/pypi/python-etcd``.
Like all sdb modules, the etcd module requires a configuration profile to
be configured in either the minion or master configuration file. This profile
requires very little. In the example:
.. code-block:: yaml
myetcd:
driver: etcd
etcd.host: 127.0.0.1
etcd.port: 2379
The ``driver`` refers to the etcd module, ``etcd.host`` refers to the host that
is hosting the etcd database and ``etcd.port`` refers to the port on that host.
.. code-block:: yaml
password: sdb://myetcd/mypassword
