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! :) 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. Docker is a great tool, and I'm glad it's…

Off topic: how do I create slides like this? What did you use to create 'em?

What's old is new. You're describing containers I think.

See: User Mode Linux, available since somewhere around 2002 or 2003.

tl;dr It's basically a tech demo for systemd, and the systemd-nspawn tool in particular (which you might recall recently gained Docker format support).

Yep, and not particularly interesting. It is a catchy title and some showcase for Systemd.

Much like docker.

Not really the same, since that runs a full kernel for each "container". OpenVZ is a better example (and is, in fact, the precursor of LXC).

I haven't used Docker myself. So what value add does Docker provide?

So we should also add Docker to the chimera that systemd is becoming?
