Memcached sdb Module
:maintainer: SaltStack
:maturity: New
:depends: python-memcached
:platform: all
This module allows access to memcached using an ``sdb://`` URI. This
package is located at ``https://pypi.python.org/pypi/python-memcached``.
Like all sdb modules, the memcached 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
mymemcache:
driver: memcached
memcached.host: localhost
memcached.port: 11211
The ``driver`` refers to the memcached module, ``host`` and ``port`` the
memcached server to connect to (defaults to ``localhost`` and ``11211``,
and ``mymemcached`` refers to the name that will appear in the URI:
.. code-block:: yaml
password: sdb://mymemcached/mykey
