Running containers without Docker
What is the motivation and benefit for running containers without docker?Docker is by far the more mature and adopted development tool. It also runs great on windows, macos and linux.While k8s can run containers via the rkt runtime, it's still pretty new and will probably introduce unnecessary headache and edge cases.Docker also has a head start on a vibrant ecosystem for base images.In my opinion it would be better to focus on docker, and when rkt gets there it shouldn't be much of an issue to switch if desired.
