Enviroment

The environment consists of 1 Server Node which is a (VM.Standard.E2.2) Shape runnning ubuntu, and the another VM called ClientNode1 Which is a VM.Standard.E2.Micro running ubuntu

My LAN is 10.10.1.0/24

Please ensure that port 22 and 8140 are allowed on each machine’s firewall, and that both machines can reach one another (i.e. ping or traceroute)

Setting up hostnames

  1. For the Client and Server to recognized one another, hostnames must be given on both machines.

Note: I use Helix, but nano, emacs, and vim is fine

sudo hx /etc/host   
[insert ip] puppetserver
[insert ip] puppetclient

Installing Puppet

It’s safe to assume, apt has been updated and upgraded.

Puppet Server

The puppet server is used as the main controller for each puppet agent/client. For instance, I am running a lamp stack config on my server, and so when I edit the config; I can push those edits remotely to each puppet agent on a machine. Further, I can also request those edits from the agent itself.

And the puppet server is only to be installed onto the server node/machine.

  1. Running Apt
wget https://apt.puppetlabs.com/puppet8-release-jammy.deb
sudo dpkg -i puppet8-release-jammy.deb
sudo apt update
sudo apt install puppetserver
  1. Editing Puppet Memory (if needed)

The -Xms1g and =Xmx1g is where you can edit, 1g simply means 1 GB of memory

sudo hx /etc/default/puppetserver
JAVA_ARGS="-Xms1g -Xmx1g -Djruby.logger.class=com.puppetlabs.jruby_utils.jruby.Slf4jLogger"
  1. Service management
sudo systemctl start puppetserver
sudo systemctl enable puppetserver
sudo systemctl status puppetserver

Puppet Agent

Likewise, assume apt is updated and upgraded.

The Puppet Agent is just the client, so only client machines/nodes need it.

  1. Installing via Apt
sudo apt install puppet-agent -y
  1. Editing Config
sudo hx /etc/puppet/puppet.conf
  1. Add the following to the config
[main]
certname = puppetclient
server = puppetserver

If you gave different names to your hostnames, then make sure to follow that.

  1. Service Management
sudo systemctl start puppet
sudo systemctl enable puppet
sudo systemctl status puppet

Certifcate Management

On the Puppet Server Node, do the following:

  1. List Pending and Available Certificates
sudo /usr/bin/puppetserver ca list --all
  1. Sign those certs
sudo /usr/bin/puppetserver ca sign --all
