Lock an environment's cookbooks

Chef Infra (archive)

Hey Guys,

Is there any way to take an environment, which currently has no cookbook
version constraints, and set each cookbook version to the latest of whats
deployed on my chef server? Would really suck to have to get the expanded
run list and do “knife node show” on each… Any other way about this ?

"knife cookbook list" will show you all of the cookbooks currently
deployed and the latest versions of each. You can see all the versions
of a particular cookbook with "knife cookbook show FOO". You can then
take those versions and set them in your environment.

I've done this once before using shef, and it turns out to be pretty easy.

  1. Fire up shef like so

% shef -z -c ~/.chef/knife.rb

  1. Load your environment

chef > env = Chef::Environment.load('YOUR_ENV_HERE')

  1. Grab your cookbook versions and format to taste.

chef > env.cookbook_versions
=> {"build-essential"=>"= 1.0.0", … }

  1. Include your output in environments/YOUR_ENV_HERE.rb

  2. Upload

% knife environment from file environments/YOUR_ENV_HERE.rb

HTH,

Jeremy

Hey John,

I just use something like this to get a formatted list that will work:

knife cookbook list | awk '{print """$1"" => "= "$2"""}' > new_env.rb

use your favorite editor to properly edit new-env.rb and then knife environment from file to your hearts content.
