Description

Configures various YUM components on Red Hat-like systems. Includes LWRP for managing repositories and their GPG keys.

Based on the work done by Eric Wolfe and Charles Duffy on the yumrepo cookbook.

Requirements

RedHat Enterprise Linux 5, and 6 distributions within this platform family.

Attributes

• yum['exclude']

  • An array containing a list of packages to exclude from updates or installs. Wildcards and shell globs are supported.
  • Defaults to an empty exclude list.

• yum['installonlypkgs']

  • An array containing a list of packages which should only be installed, never updated.
  • Defaults to an empty install-only list.

• yum['epel_release']

  • Set the epel release version based on node['platform_version'].
  • Defaults to the most current release of EPEL, based on the major version of your platform release.

• yum['ius_release']

  • Set the IUS release to install.
  • Defaults to the current release of the IUS repo.

Recipes

default

The default recipe does nothing.

yum

Manages the configuration of the /etc/yum.conf via attributes. See the aforementioned Array attributes yum['exclude'] and yum['installonlypkgs'].

epel

Installs the EPEL repository via RPM. Uses the yum['epel_release'] attribute to select the right version of the repository package to install. Also uses the node's platform version (as an integer) for the major release of EL.

On Amazon Linux, the built-in EPEL repository is activated using yum-config-manager --quiet --enable epel. This ignores the node['yum']['epel_release'] attribute in favor of the version configured in the Amazon Linux AMI.

ius

Installs the IUS Community repositories via RPM. Uses the node['yum']['ius_release'] attribute to select the right versino of the package to install.

The IUS repository requires EPEL, and includes yum::epel as a dependency.

Resources/Providers

key

This LWRP handles importing GPG keys for YUM repositories. Keys can be imported by the url parameter or placed in /etc/pki/rpm-gpg/ by a recipe and then installed with the LWRP without passing the URL.

Actions

• :add: installs the GPG key into /etc/pki/rpm-gpg/
• :remove: removes the GPG key from /etc/pki/rpm-gpg/

Attribute Parameters

• key: name attribute. The name of the GPG key to install.
• url: if the key needs to be downloaded, the URL providing the download.

Example

# add the Zenoss GPG key
yum_key "RPM-GPG-KEY-zenoss" do
  url "http://dev.zenoss.com/yum/RPM-GPG-KEY-zenoss"
  action :add
end
    
# remove Zenoss GPG key
yum_key "RPM-GPG-KEY-zenoss" do
  action :remove
end

repository

This LWRP provides an easy way to manage additional YUM repositories. GPG keys can be managed with the key LWRP. The LWRP automatically updates the package management cache upon the first run, when a new repo is added.

Actions

• :add: creates a repository file and builds the repository listing
• :remove: removes the repository file

Attribute Parameters

• repo_name: name attribute. The name of the channel to discover

• description. The description of the repository

• url: The URL providing the packages

• mirrorlist: Default is false, if true the url is considered a list of mirrors

• key: Optional, the name of the GPG key file installed by the key LWRP.

• enabled: Default is 1, set to 0 if the repository is disabled.

• type: Optional, alternate type of repository

• failovermethod: Optional, failovermethod

• bootstrapurl: Optional, bootstrapurl

Example

# add the Zenoss repository
yum_repository "zenoss" do
  name "Zenoss Stable repo"
  url "http://dev.zenoss.com/yum/stable/"
  key "RPM-GPG-KEY-zenoss"
  action :add
end
    
# remove Zenoss repo
yum_repository "zenoss" do
  action :remove
end

Usage

Put recipe[yum::yum] in the run list to ensure yum is configured correctly for your environment within your Chef run.

Use the yum::epel recipe to enable EPEL, or the yum::ius recipe to enable IUS, per Recipes section above.

You can manage GPG keys either with cookbook_file in a recipe if you want to package it with a cookbook or use the url parameter of the key LWRP.
