[chef] Re: environment includes? role includes? run list in the environment?

[Peter Donald < >]

Hi,

IMHO you are doing it wrong. :) (See [1])

We have the exact same problem. Different data centers require
different runlists and/or configuration. When presented with the
prospect of doing logic that may require evolution/versioning I tend
to see that the best place to do that in chef atm is in a cookbook.

So we typically will do the logic in such a big switch or decision
tree of some type. Our nameservers are not chef managed so they are a
bunch of static configurations and we have something like the
following in a recipe in our base cookbook.

if '8ND' == node['datacenter']
  node.override['resolver']['nameservers'] = ["X.X.X.X"]
elsif 'BWD' == node['datacenter']
  node.override['resolver']['nameservers'] = ["X.X.X.X", "X.X.X.X"]
....
elsif 'VAGRANT' == node['datacenter']
  node.override['resolver']['nameservers'] = ["10.61.69.22", "10.61.69.23"]
else
  raise "Unknown datacenter #{node['datacenter']}"
end

We also use this approach to decide whether or not to include certain recipes.

At other times we use search to derive the configuration and then
limit the criteria by environment/datacenter.
