Puppet 101: PuppetServer

In my last blog post, I explained how to install and configure a puppet agent, in this blog post I am going to install and configure a Puppetserver. It will help us as a provisioner orchestrator, this means that it will be responsible for providing the resource definition of what we want to install in a node where the puppet agent was installed previously.

Development environment:

• Ubuntu 18.04 LTS
• Tmux
• Visual Studio Code and the puppet extension
• VirtualBox
• Vagrant

Recommendations:

• ruby version manager RVM
• ruby version 2.3.3

Let's spin up a vagrant box with centos 7 and Puppetserver installed.

puppetserver.sh

#!/usr/bin/env bash
# This bootstraps Puppet on CentOS 7.x
set -e
# (Optional) remove manually placed repo file
/bin/rm -f /etc/yum.repos.d/puppetlabs*
REPO_URL="http://yum.puppetlabs.com/puppet5/puppet5-release-el-7.noarch.rpm"
if [ "$EUID" -ne "0" ]; then
echo "######## This script must be run as root. ########" >&2
exit 1
fi
if which puppet > /dev/null 2>&1; then
echo "######## Puppet is already installed. ########"
exit 0
fi
# Install wget
echo "######## Installing wget... ########"
yum install -y wget > /dev/null
# Install puppet labs repo
echo "######## Configuring PuppetLabs repo... ########"
repo_path=$(mktemp)
wget --output-document="${repo_path}" "${REPO_URL}" 2>/dev/null
rpm -i "${repo_path}" >/dev/null
# Install Puppet...
echo "######## Installing puppet && Start puppet services ########"
yum install -y puppetserver > /dev/null
ruby_version=2.3.0
echo "######## Installing Ruby ########"

\curl -sSL https://raw.githubusercontent.com/wayneeseguin/rvm/stable/binscripts/rvm-installer | sudo bash -s stable --ruby=${ruby_version} > /dev/null

sed -i 's/-Xms2g/-Xms256m/g' /etc/sysconfig/puppetserver
sed -i 's/-Xmx2g/-Xmx256m/g' /etc/sysconfig/puppetserver
systemctl start puppetserver
systemctl start puppet
echo "######## Puppet installed! ########"

Vagrantfile

echo 'sudo su' >> /home/vagrant/.bashrc

end

Check if the puppetserver and the puppet service are running:
