Register the nodes with the Puppet Master

At this point you the have OS installed configured on all nodes. Fuel has also made sure that these nodes have been configured, with Puppet installed and pointing to the Puppet Master, so the nodes are almost ready for deploying OpenStack. As the last step, you need to register the nodes in Puppet master. Do this by running the Puppet agent:

puppet agent --test

This action generates a certificate, sends it to the Puppet Master for signing, and then fails. That's fine. It's exactly what we want to happen; we just want to send the certificate request to the Puppet Master.

Once you've done this on all four nodes, switch to the Puppet Master and sign the certificate requests:

puppet cert list
puppet cert sign --all

Alternatively, you can sign only a single certificate using:

puppet cert sign fuel-XX.your-domain-name.com

Now return to the newly installed node and run the Puppet agent again:

puppet agent --test

This time the process should successfully complete and result in the "Hello World from fuel-XX" message you defined earlier.
