yum-epel Cookbook
============
[![Build Status](https://travis-ci.org/chef-cookbooks/yum-epel.svg?branch=master)](http://travis-ci.org/chef-cookbooks/yum-epel)
[![Cookbook Version](https://img.shields.io/cookbook/v/yum-epel.svg)](https://supermarket.chef.io/cookbooks/yum-epel)

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`.

Requirements
------------
#### Platforms
* RHEL/CentOS and derivatives
* Fedora

#### Chef
* Chef 11+

#### Cookbooks
* yum version 3.2.0 or higher

----------
The following attributes are set by default

``` ruby

```

``` ruby
default['yum']['epel']['repositoryid'] = 'epel'
default['yum']['epel']['description'] = 'Extra Packages for Enterprise Linux 6 - $basearch'
default['yum']['epel']['mirrorlist'] = 'http://mirrors.fedoraproject.org/mirrorlist?repo=epel-5&arch=$basearch'
default['yum']['epel']['gpgkey'] = 'http://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-6'
default['yum']['epel']['failovermethod'] = 'priority'
default['yum']['epel']['gpgcheck'] = true
default['yum']['epel']['enabled'] = true
default['yum']['epel']['managed'] = true

```

``` ruby

default['yum']['epel-testing-source']['enabled'] = false
default['yum']['epel-testing-source']['managed'] = false
```

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.

```ruby
  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://dl.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'
```
