yum-epel Cookbook

Extra Packages for Enterprise Linux (or EPEL) is a Fedora Special Interest Group that creates, maintains, and manages a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL), CentOS and Scientific Linux (SL), Oracle Linux (OL).

The yum-epel cookbook takes over management of the default repositoryids shipped with epel-release. It allows attribute manipulation of epel, epel-debuginfo, epel-source, epel-testing, epel-testing-debuginfo, and epel-testing-source.

• RHEL/CentOS and derivatives

Recipes

• default - Walks through node attributes and feeds a yum_resource
• parameters. The following is an example a resource generated by the
• recipe during compilation.

  yum_repository 'epel' do
    mirrorlist 'http://mirrors.fedoraproject.org/mirrorlist?repo=epel-5&arch=$basearch'
    description 'Extra Packages for Enterprise Linux 5 - $basearch'
    enabled true
    gpgcheck true
    gpgkey 'http://download.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL'
  end

Usage Example

To disable the epel repository through a Role or Environment definition

default_attributes(
  :yum => {
    :epel => {
      :enabled => {
        false
       }
     }
   }
 )

Uncommonly used repositoryids are not managed by default. This is speeds up integration testing pipelines by avoiding yum-cache builds that nobody cares about. To enable the epel-testing repository with a wrapper cookbook, place the following in a recipe:

node.default['yum']['epel-testing']['enabled'] = true
node.default['yum']['epel-testing']['managed'] = true
include_recipe 'yum-epel'

More Examples

Point the epel repositories at an internally hosted server.

node.default['yum']['epel']['enabled'] = true
node.default['yum']['epel']['mirrorlist'] = nil
node.default['yum']['epel']['baseurl'] = 'https://internal.example.com/centos/6/os/x86_64'
node.default['yum']['epel']['sslverify'] = false

include_recipe 'yum-epel'
