Hi guys, My blog entry has a lot of the design patterns, and I quote a bunch of others. It's a good backgrounder: http://newgoliath.wordpress.com/2013/03/08/orchestration-consistency-and-community-cookbooks/
This past sprint I started the code updates. This coming sprint I'll be finishing them up, teamed up with Wayne from our team. If we are to create a short list of the pattern, here it is: * no attribute l-values in recipes * no OS detection in recipes * define all OS dependent variables in attibutes/default.rb * define all l-values in attirubtes/default.rb * do not use recipes/default.rb * recipes should be named as if they were methods * in recipes, oft-repeated patterns should be abstracted into a function in a library/<objectname>.rb * example: https://github.com/att-cloud/cookbook-openstack-common/blob/master/libraries/endpoints.rb On Wed, Mar 13, 2013 at 1:56 PM, James Tan <ja...@suse.de> wrote: > On 03/07/2013 11:13 AM, Vincent Untz wrote: > > Hi, > > > > First, thanks for the overview on attribute injection in yesterday's > > call.
