[chef] Re: Re: How to version to a role?

Adam, that makes perfect sense

I was just confused by the fact that the roles appear on the cookbooks tab of the WebUI and that they all show the version number 0.0.0

Think about it like this. You have a tool at your disposal to describe desired state, and to encode any kind of tricky transitions around how to move from one state to the next. You can either:

A) Encode those transitions in code
B) Encode those transitions in branches, dependencies, and version constraints

To put it more plainly, a Role should define attributes and run-lists for your infrastructure, and the run-lists may vary by environment. If you need to have custom code to make sure both an old and a new version of a component works, encode that in the recipes, rather than trying to obfuscate it with versions.

Best,
Adam
