I feel like some of the explanations on berkshelf on the internet are confusing.
So i felt like doing a small write up myself
berkshelf is pretty much a replacement for the “knife cookbook” command.
The big win with berkshelf is that it also resolves dependencies of a cookbook like apt or yum.
It reads a file called “Berksfile” for other cookbooks the current cookbook needs and what repositories to fetch them from and pulls them to your local system.
I will use the logstash cookbook at https://github.com/lusis/chef-logstash as an example
If you read the Berksfile at https://github.com/lusis/chef-logstash/blob/master/Berksfile
it will show you what other cookbooks the logstash cookbook needs
So in order to get going
gem install berkshelf git clone firstname.lastname@example.org:lusis/chef-logstash.git cd logstash berks install berks upload
That installed berkshelf, cloned the logstash cookbook, resolved dependencies for the logstash cookbook and uploaded logstash cookbook and its dependencies to your chef-server
Additionally berkshelf installs its configuration file at : ~/.berkshelf/config.json
You may need to edit some stuff there to match your ~/.chef/knife.rb file
