Kitchen converge doesn't work with docker fresh installation

👻 Issues with kitchen and Docker integration

When trying to run kitchen converge icinga-ubuntu-2204 I got the following error:

-----> Creating <icinga-ubuntu-2204>...
>>>>>> ------Exception-------
>>>>>> Class: Kitchen::ActionFailed
>>>>>> Message: 1 actions failed.
>>>>>>     Failed to complete #create action: [undefined method `each' for nil:NilClass] on icinga-ubuntu-2204
>>>>>> ----------------------
>>>>>> Please see .kitchen/logs/kitchen.log for more details
>>>>>> Also try running `kitchen diagnose --all` for configuration

After checking that everything was well configured I tried the debug option kitchen converge --debug icinga-ubuntu-2204
In the ~/.kitchen/logs/kitchen.log file I found the following error:

E, [2022-10-25T14:54:47.745961 #68914] ERROR -- Kitchen: -Composite Exception--

By opening the gems file I found the following code:

      def docker_config_creds
        return @docker_config_creds if @docker_config_creds

        @docker_config_creds = {}
        config_file = ::File.join(::Dir.home, ".docker", "config.json")
        if ::File.exist?(config_file)
          JSON.load_file!(config_file)["auths"].each do |k, v|
            next if v["auth"].nil?

            username, password = Base64.decode64(v["auth"]).split(":")
            @docker_config_creds[k] = { serveraddress: k, username: username, password: password }
          end
        else
          debug("~/.docker/config.json does not exist")
        end

        @docker_config_creds
      end

As you can see the loop tries to iterate an "auths" key in ~/.docker/config.json that doesn't exist.

In order to fix the bug, the user must run docker login -u your_docker_username "https://index.docker.io/v1/" or manually add the following "auths" content:

{
  "credsStore": "desktop",
  "auths": {
      "https://index.docker.io/v1/": {}
  }
}
