Learn Puppet

This setup is helping me learn more about Puppet. I learn by doing, and this is me doing Puppet.

Quickstart

1. Start the master and node.

   cd puppetmaster
   vagrant up
   cd ../puppetnode
   vagrant up

2. Run vagrant rsync-auto to sync files to puppetmaster.

   cd puppetmaster
   vagrant rsync-auto

3. Sign the puppetnode certificate. Pay attention to where we are running each of these commands (master vs node).

   # Submit a certificate signing request on the node.
   [vagrant@puppetnode] sudo /opt/puppetlabs/bin/puppet agent --verbose --no-daemonize --onetime
   
   # Sign the cert on the master.
   [vagrant@puppetmaster] sudo /opt/puppetlabs/bin/puppetserver ca sign --certname puppetnode.localdomain
   
   # Confirm a successful connection on the node.
   [vagrant@puppetnode] sudo /opt/puppetlabs/bin/puppet agent --verbose --no-daemonize --onetime
   

4. Enable the puppet agent service.

   sudo /opt/puppetlabs/bin/puppet resource service puppet ensure=running enable=true
