How is this whole #ansible #molecule tool so bad.
It has mountains of documentation examples that literally do not work at all.
Mentions a whole slew of configuration parameters that seem entirely ignored.
And worst of all, it forces a very particular directory structure that makes sharing these huge piles of boilerplate across roles and playbooks, impossible...
But sadly it's the only tool in human existence to seamlessly allow dind testing with systemd based containers.
