Hi guys,
This has been an interesting thread to read. I'd like to chime in on
the side of it's hard to have a canonical or recommended way of doing
things. It's actually the flexibility that chef provides in being able
to do things different ways that's allowed me to introduce it to my
team.
It probably makes sense to just explain the make up of my team, our
environment and how we're using chef.
I don't work for a tech company. I work for one of the larger
environmental non-profits. I'm part of an 8 person enterprise team of
admins and engineers that support a mix of Widows, Redhat Linux and a
couple HPUX unix servers. Currently chef is our configuration
management tool we're rolling out on Redhat Linux. In the future we
plan to use chef to manage a nagios agent on our Windows hosts since
the server is built with chef. All other configuration for Windows is
done via GPO.
No one on our team uses ruby. Me and one other guy are the primary
Linux scripters, I prefer python and my other guy uses perl. We have a
couple other engineers that can kick around with both perl and python.
99% of our chef recipes are currently bash. Why? Because that's the
one "language" we all feel comfortable backing each other up on.
Recently I've for the most part gotten away from templates, just using
files to push stuff out. It was easier for the rest of the team to
follow along with rather than trying to learn the template language.
My team is constantly slammed. We all are heavily involved in project
work while also being responsible for all KLO. To get things like chef
inside our environment I had to do it in the scope of a project where
I padded some time in order to get the chef implementation in. My team
doesn't have the time to learn ruby and whole new way of doing things.
We also have some very opinionated people about how exactly everything
should be done... oh yea, we're sysadmins.
I imagine a lot of other people have environments similar to ours, not
in the tech sense but in the "have to get things done and get it done
now" lifestyle of the job. Otherwise, you wouldn't need a
configuration management system in the first place, you'd have time to
manage it yourself. Now, I can't imagine there's ever going to be a
chef guide that says write all yours recipes with code blocks of bash.
However, I can tell you it's the best possible implementation for my
team.
Operations environments are different every where. Especially with
older organizations. It's one thing to build ground up with a tool
like chef, but introducing it to an existing ecosystem of scripts,
policies and procedures is something that there's not going to be a
catch all solution for. The answer "there's a lot of ways to do it" is
exactly the answer that makes Chef work for us.
