Which cookbook version wins in this case?

Chef Infra (archive)
1

Say I have a web_role cookbook, and its metadata.rb file looks like this

depends ‘apache’, '= 1.0.0’
depends ‘webapp’, '= 1.0.0’
depends ‘someapp’, ‘= 1.0.0’

…and my webapp cookbook’s metadata.rb files look like…

depends ‘apache’ # Not pinned to any version

On the server I have apache@1.0.0mailto:apache@1.0.0 and apache@1.2.0mailto:apache@1.2.0 versions of the apache cookbook

Now if I add my web_role cookbook to my node’s run list, which version of the apache cookbook will converge, 1.0.0 defined in the web_role’s metadata.rb file, or the 1.2.0, latest version on the chef server?

1.0.0 should win. It satisfies all requirements, where 1.2.0 does not.

Thanks. I’m testing this now. How do I show the cookbooks’ version that converged on the node? “knife node show” of course shows the run list, but not the cookbooks’ versions?

You could always examine the cookbook on your node - it should be in chef's
cache directory after convergence. There may be a knife plugin somewhere
that will show you cookbook version resolution based on a node's run list.

I believe you'll find the versions used at the top of the client log as
well, e.g. "nginx@3.0.1"

Noah wrote a knife plugin to ask the server what cookbooks it would give you: GitHub - coderanger/knife-solve: A knife plugin to see the Chef Server version solver solution for a given set of cookbooks.

You may use a report handler for this:

An example one with this use case is available on the doc site here:
