How complex is your Puppet environment?

Say you're a medium sized Internet company with thousands of managed servers. Would you say your Puppet server environment is a relatively simple straightforward deploy or have you added various components to it? If a new person were to join your team, how long would it take them to get up to speed on your Puppetserver environment with module deploys, etc? Did you spend much time designing the system beyond implementing it as documented? Thanks!

thanks for the replies so far. I guess I'm not too far off in having a system that takes a little while to understand. Seemed like it might be overly complex, but perhaps that's the norm.

One of the things I'm taking into consideration is how capable all of the admins are w/r/t programming and such vs just being recipe/script runners. We have a lot of junior administrators coupled with a few senior ones. This actually make me choose to avoid using the roles/profiles pattern because I didn't think the junior ones could handle it. Instead, I'm having myself and the senior admins create modules with class parameters usable within hiera. This allows the junior admins to stay within hiera when it comes to making changes and keeping them from the Puppet stuff. That way its just yaml vs Puppet DSL/ruby.

I would say that 99% of data center administration could be handled by the documented setup of r10k + roles/profiles. There are plenty of github repos to choose from with this stuff already in place. Then tweak as needed.

Puppet does take a while to grasp. If your admins are decent scripters/programmers, I think they could manage learning it over several months of practice.

  • I'd say, “it's fairly straight-forward”.
  • If it isn't the only task the new person has, I'd guess it takes them about half year, to get up to a comparable speed as we already have.
  • Designing: Yeah, Puppet is a tool. Once you know your tool, you can handle it without giving much thought to it. It's usually the situation, the software, which consumes most of the time: “How can I automatically (unattended) change the situation?” Because you usually know, how to perform tasks manually, but there isn't necessarily a method for automatized manipulation.
