Installing Gem into ChefDK via Chef

I want to install a Gem (kitchen-docker) into ChefDK's Gem path.

What is the best way to install this Gem via Chef itself? Is there a more clever solution than the following?

execute "chef gem install kitchen-docker" do
  user "jenkins"
  not_if "chef gem list | grep ^kitchen-docker"
end

Some background information: I want to use ChefDK in Jenkins on our CI server to do cookbook testing. The CI server itself should be provisioned by Chef, of course.

Run this:

chef gem install kitchen-docker

This install gen un chefdk path.

Best regards!

This snippet worked for me to create a resource allowing me to do chef_dk_gem "kitchen-dokken"

It's a lot hackier than I'd like but because of issues with CHEF-2288 I otherwise had a lot of troubles getting the gem into my target user, and having the env variables for GEM* setup correctly with chef-dk

action :install do
    include_recipe "chef-dk"
    execute "setup chefdk gem #{gem_name}" do
        command "runuser #{gem_user}  -c '/opt/chefdk/embedded/bin/gem install #{gem_name}'"
        not_if "/opt/chefdk/embedded/bin/gem list #{gem_name} | grep #{gem_name}'", :user => gem_user
    end
end

Apparently, in order to install a chef gem system-wide (into /opt/chefdk/), the parameter --no-user-install of the gem command can be used through the gem_package resource:

gem_package "kitchen-docker" do
  gem_binary "/opt/chefdk/embedded/bin/gem"
  options "--no-user-install"
end

This installs the gem and makes it available to all users running chefdk on the system.
