##Overview

The yum module provides several repositories available for RPM based RHEL 6 clones like CentOS or Scientific Linux.

##Module Description

The yum module provides several repositories available for RPM based RHEL 6 clones like CentOS or Scientific Linux.

##Setup

###What yum affects

• yum package.
• yum configuration file.
• yum repository configuration.

###Beginning with yum

include '::yum' is enough to get you up and running if the parameters point to proper values. If you wish to pass in parameters like which repositories to use then you can use:

class { '::yum':
  repo_foreman => true,
}

##Usage

All interaction with the yum module can do be done through the main yum class. This means you can simply toggle the options in the yum class to get at the full functionality. You also have the possibility to include classes in the order you need.

###I just want yum, what's the minimum I need?

include '::yum'

###I just want to add CoreOS, EPEL, SC and Puppet plus Foreman

class { '::yum':
  repo_foreman => true,
}

##Reference

##Limitations

This module has been built on and tested against Puppet 3.7 and higher.

The module has been tested on:

• CentOS Linux 6, 7
• Scientific Linux 6

Testing on other platforms has been light and cannot be guaranteed.

This module does currently only support a limited set of distributions and need to be reworked for other distributions as well. I use static files instead of the yum provider to stay in sync with the files that the repository creators deliver. Some more parameters can be implemented, i.e., activating or disabling repositories and features is currently only possible inside the template. That should be implemented as parameters in the future.

##Development

If you like to add or improve this module, feel free to fork the module and send me a merge request with the modification.
