I love the idea of Chef and Puppet. And to me, that idea is “let’s just declare everything we want to be true about a server and it can magically spring into existence.” Better yet, of course, is trying it out locally and then pushing it out, as Chef plus Vagrant promises.
Especially that server is declared as “NGinX should be installed” rather than “download this file, copy it here, unzip and build it…” Chef and Puppet, each in their way, is a possible vision of that future.
Of course, right now they are not ready for casual use.
But Aren’t They Both A Few Years Old?
I started with Chef several years ago. It was a bit of a mess – significant changes like Lightweight Resources and Providers that were supposed to change everything and the rewrites that followed. Berkshelf, and then later its acquisition and significant rewrites.
Basically, a fair bit of churn and chaos. Just what you’d expect of a new idea that’s turning into something you can use.
Puppet, of course, was doing almost exactly the same thing with the Puppet 2 to Puppet 3 transition, modules and whatnot.
And now they’re both still churning with things like Librarian, a Bundler for Chef and Puppet. And Berkshelf, Test Kitchen and other fun tool changes.
To be clear: each and every one of these is basically a good idea. Some day, when Chef integrates them nicely, I think it will be an amazing solution.
Is This Just Theory?
Right now, the problem manifests in ways like the fact that you can’t use the latest version of the build-essential cookbook (one of the very basic ones) with the version of Chef that comes with Vagrant – you have to figure out you need a different Chef version, and use one of several hacks or plugins to make it work. This isn’t really documented… You just have to figure it out.
Plus, many Chef cookbooks don’t yet support the new LWRPs, and many Puppet cookbooks don’t support the Puppet-3-style modules, and all kinds of things are broken because they’re “old” – often only six to twelve months out of date, but that’s already old.
There are still a lot of rough edges.
Chef and Puppet will both be amazing, given time. However, as a non-Devops person… You can expect that they’ll both be changing a lot for awhile, and that they’ll be unfriendly to casual users for awhile yet. Upgrades will remain painful, probably for at least another year or two.
And likely more.
I look forward to the future, when a well-written year-old tutorial doesn’t require three or four updates to work with recent versions of everything. And we’ll get there.
We’re just not there yet.
