 As for the main configuration file ''/etc/puppet/puppet.conf'' I leave the Debian standard for what it is.

 Of course, before testing your code, you should first run it through ''puppet parser validate'' and ''puppet-lint''. However, this is not a Puppet code manual, you should check their [[https://puppet.com/docs|excellent documentation]] for that.
-===== Connecting Clients =====
+===== Clients =====
-Of course, your Puppet master will be useless if it only manages itself. To connect clients to your Puppet master, make sure it is reachable on port 8140/TCP (both IPv4 and IPv6 work).

-<code>
+<code ini>
 [agent]

-Afterwards, run ''puppet agent -t''. This will create a certificate request on the Puppet master. There, run ''puppet cert list''((That might yield a warning that this is deprecated, but for now that is still the way to go.)) and you will get an output similar to this((In case you run full IPv6, there might also be a warning on routing issues, just ignore that. It is a bug.)):

-To accept that certificate just run ''puppet cert sign client.system.tld'' and you are good to go. From now on, that system will be managed by your Puppet master. To test this you can run a ''puppet agent -t'' on the client.

-==== Removing clients ====

-In case you need to remove (decommission) a client, you can list all available certificates with ''puppet cert list -a'' and then ''puppet cert clean <client.name.tld>''. Don't forget to remove that client from backup and monitoring ;-)

 ====== What next? ======
-Now, it might be a good idea to manage your Puppet code from your workstation using [[:apps:git|git]]. That way you do not need to log in to the Puppet master all the time to make changes to your code as root.
