yum-centos Cookbook

The yum-centos cookbook takes over management of the default repositoryids that ship with CentOS systems. It allows attribute manipulation of base, updates, extras, centosplus, contrib, and fasttrack.

default['yum']['extras']['repositoryid'] = 'extras'
default['yum']['extras']['description'] = 'CentOS-$releasever - Extras'

default['yum']['extras']['enabled'] = true
default['yum']['extras']['managed'] = true
default['yum']['extras']['gpgcheck'] = true
default['yum']['extras']['gpgkey'] = 'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-$releasever'

default['yum']['centosplus']['repositoryid'] = 'centosplus'
default['yum']['centosplus']['description'] = 'CentOS-$releasever - Centosplus'
default['yum']['centosplus']['mirrorlist'] = 'http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus'
default['yum']['centosplus']['enabled'] = false
default['yum']['centosplus']['managed'] = false
default['yum']['centosplus']['gpgcheck'] = true
default['yum']['centosplus']['gpgkey'] = 'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-$releasever'

default['yum']['updates']['repositoryid'] = 'updates'
default['yum']['updates']['description'] = 'CentOS-$releasever - Updates'
default['yum']['updates']['mirrorlist'] = 'http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates'
default['yum']['updates']['enabled'] = true
default['yum']['updates']['managed'] = true
default['yum']['updates']['gpgcheck'] = true
default['yum']['updates']['gpgkey'] = 'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-$releasever'

default['yum']['fasttrack']['repositoryid'] = 'fasttrack'
default['yum']['fasttrack']['description'] = 'CentOS-$releasever - fasttrack'
default['yum']['fasttrack']['mirrorlist'] = 'http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=fasttrack&infra=$infra'
default['yum']['fasttrack']['enabled'] = false
default['yum']['fasttrack']['managed'] = false
default['yum']['fasttrack']['gpgcheck'] = true
default['yum']['fasttrack']['gpgkey'] = 'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-$releasever'

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 'base' do
    mirrorlist 'http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os'
    description 'CentOS-$releasever - Base'
    enabled true
    gpgcheck true
    gpgkey 'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-$releasever'
  end

Usage Example

To disable the CentOS Extras repository through a Role or Environment definition

default_attributes(
  :yum => {
    :extras => {
      :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 CentOS Plus repository with a wrapper cookbook, place the following in a recipe:

node.default['yum']['centosplus']['managed'] = true
node.default['yum']['centosplus']['enabled'] = true
include_recipe 'yum-centos'

More Examples

Point the base and updates repositories at an internally hosted server.

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

include_recipe 'yum-centos'
