I’ve started playing with various incarnations of “in a box” OpenStack setups to familiarize myself with OpenStack, among them DevStack and Ubuntu OpenStack. The OpenStack Chef Repo looks promising to me, as it gives you a good starting point, but can easily be extended to more complex lab setups, or even full productions environments.

The only problem? This error:

I’m far from an expert in Chef, so it took me a bit of searching and experimenting. Luckily, the solution is rather simple:

$ chef gem list -d '^chef-provisioning$'

The next version of ChefDK will likely come with this updated version of chef-provisioning, but until then, this should do the trick.
