Docker Considered Harmful (2016)
Docker by itself probably doesn't make any sense to an engineer until they get a chance to see kubernetes in action. There is nothing more awesome than seeing, on the fly, your worker pool being scaled out by 100x by nothing more than  kubectl --context k8s-uw1a-gcp -n customerx scale deploy someapp_worker --replicas 100

to make you appreciate what docker can do for you.
