Docker without Docker
Author here - I'm working on a blog post for this and didn't expect this to be posted on HN so soon, but I guess that's what I should expect for posting a link to it in another HN comment! :)<p>These slides correspond to a workshop I conducted a week ago demonstrating the internals of Docker and how Docker containers can be run without using any of the Docker tools or runtime.<p>Docker is a great tool, and I'm glad it's gained so much traction. But containerization is still new to many people, and even then there's still a lot of confusion about the difference between Docker and containerization in general. The goal of this presentation isn't to discourage anyone from using Docker, but to outline the lay of the land for people interested in using containers.<p>Personally, I run containers both with systemd and with Docker. The good news is that it's really easy to switch from one to the other, so there's very little cost to trying it out both ways.
