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, and contrib.

Requirements

• Chef 11 or higher
• yum cookbook version 3.0.0 or higher

Attributes

The following attributes are set by default

default['yum']['base']['repositoryid'] = 'base'
default['yum']['base']['mirrorlist'] = 'http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os'
default['yum']['base']['description'] = 'CentOS-$releasever - Base'
default['yum']['base']['enabled'] = true
default['yum']['base']['managed'] = true
default['yum']['base']['gpgcheck'] = true
default['yum']['base']['gpgkey'] = 'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6'

default['yum']['contrib']['repositoryid'] = 'contrib'
default['yum']['contrib']['description'] = 'CentOS-$releasever - Contrib'
default['yum']['contrib']['mirrorlist'] = 'http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib'
default['yum']['contrib']['enabled'] = false
default['yum']['contrib']['managed'] = false
default['yum']['contrib']['gpgcheck'] = true
default['yum']['contrib']['gpgkey'] = 'file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6'

default['yum']['extras']['repositoryid'] = 'extras'
default['yum']['extras']['description'] = 'CentOS-$releasever - Extras'
default['yum']['extras']['mirrorlist'] = 'http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=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-6'

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-6'

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-6'

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-6'
  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'
