Spacewalk
---------
**Summary:** install and configure spacewalk

This module installs spacewalk and applies basic configuration. If the
``spacewalk`` config key is present spacewalk will be installed. The server to
connect to after installation must be provided in the ``server`` in spacewalk
configuration. A proxy to connect through and a activation key may optionally
be specified.

For more information about spacewalk see: https://fedorahosted.org/spacewalk/

**Internal name:** ``cc_spacewalk``

**Module frequency:** per instance

**Supported distros:** redhat, fedora

**Config keys**::

spacewalk:
       server: <url>
       proxy: <proxy host>
       activation_key: <key>
