VMs list

  • One puppet master running Debian 7 64bits
  • One puppet client running Debian 7 64bits
  • One puppet client running Scientific Linux 5.x 64 bits
  • One puppet client running Scientific Linux 6.x 64 bits
  • One puppet client running CentOS 6.x 64 bits

Box installation

Box installation will take some time as the boxes have to be downloaded locally.

Vagrant configuration

Puppet will be boostraped using a small shell script

shell/base.sh

#!/bin/sh

if [ $(id -u) -ne 0 ]; then
  echo 'This script must be run as root.' >&2
  exit 1
fi

if which puppet > /dev/null 2>&1; then
  echo 'Puppet is already installed'
  exit 0
fi

# Add puppetlabs repo definitions
echo 'deb http://apt.puppetlabs.com wheezy main' > /etc/apt/sources.list.d/puppetlabs.list
echo 'deb http://apt.puppetlabs.com wheezy dependencies' > /etc/apt/sources.list.d/puppetlabs-dependencies.list

# Add puppetlabs repo key
apt-key adv --keyserver keyserver.ubuntu.com --recv 4BD6EC30

# Update packages list
aptitude update

# Upgrade system
# Not working yet due to debconf wanting input
#aptitude -V -y upgrade
#aptitude -V -y dist-upgrade

# Install puppet
aptitude -y install puppet
echo 'Puppet successfully installed'

Then nitial role will be set using another shell script

shell/role.sh

#!/bin/sh

if [ $(hostname) = 'puppet' ]; then
  echo 'role=puppetmaster' >> /etc/company.conf
fi
if [ $(hostname) = 'client' ]; then
  echo 'role=puppet' >> /etc/company.conf
fi

And the puppetmaster is boostraped using the puppet apply provider. The client will get its configuration from the puppetmaster using the puppet agent provider.

Two directories from the host are made available to the guest, they contain the puppet modules that will be used for the puppetmaster bootstrap: * Local puppet modules are available in the relatvie ../../dist directory * A local copy of the remote puppet modules managed using the Puppetfile is made using r10k (using a symbolicaly linked Puppetfile)

end

A copy of the hiera.yaml has been made with a custom datadir configuration to allow puppet apply to find the conf exposed into the vm by Vagrant.

Go play!

The boxes are started using

1
vagrant up
  • Connect using ssh

2
vagrant ssh master
vagrant ssh client
