Puppet install Yum package groups

Unfortunately Puppet is not able to handle the installation of Yum package groups like “Base” or “compat-libraries” and so forth. This is due to the fact that Puppet is currently not able to verify if all packages in a package group are installed after a Puppet run. To deal with package groups we need a small trick to install all packages within a package group with Puppet.

First let`s find out which packages for example are present in the Yum package group “compat-libraries”

yum group info 'compat-libraries'

Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager

Group: Compatibility Libraries
 Group-Id: compat-libraries
 Description: Compatibility libraries for applications built on previous versions of Red Hat Enterprise Linux.
 Mandatory Packages:

Now let`s make some bash mystics to make the named packages useful for Puppet:

yum group info 'compat-libraries' | grep -i "+" | sed "s/+//g" | tr -d " " | sed "s/^/'/" | sed "s/$/',/"| awk 'ORS=NR?FS:RS'

The output is this:

'compat-db47', 'compat-glibc', 'compat-libf2c-34', 'compat-libgfortran-41', 'compat-libtiff3', 'compat-openldap', 'libpng12', 'openssl098e'

Now we can prepare our Puppet class to install this package group:

class packages {
	# Install package group "compat-libraries"
	$pkggrp_compat_libraries = [ 'compat-db47', 'compat-glibc', 'compat-libf2c-34', 'compat-libgfortran-41', 'compat-libtiff3', 'compat-openldap', 'libpng12', 'openssl098e' ]
        package { $pkggrp_compat_libraries:
		ensure => installed,
		allow_virtual => false,

One thought on “Puppet install Yum package groups”

  1. This is an interesting solution, but how would you address groups which contain other groups by default. Specifically we are setting up a deployment for Scientific Linux 7 which is a RHEL derivative.

    For example, the “General Purpose System” yumgroup contains base, core, fonts, gnome-desktop, etc.

    Thanks much, we will definitely be going this route for the more specific groups which only install packages – but may end up installing more general yumgroups via kickstart (which I prefer in some cases) or a puppet exec command (which most people want to avoid as much as possible)
