WTF is a container?

Same here with docker. The ideas are nice as an application, but it's just a pain in the ass. LXC on the other hand is a breeze.

LXC is nice, as a building block, but it is far from "a breeze".

It is refreshing, however, being able to write, in a couple of hours, a setup script from scratch that debootstraps an install, chroots in there to configure it and launches the container via systemd-nspawn. Very few moving parts, excellent for development environments. Not yet something I trust in production, though.

Does LXC provide a way to automatically create new working instances (like a Dockerfile / docker-compose.yml)? I'm not quite grokking LXC in my first 10 minutes of reading...

I think you could create your own lxc template and then create new instances. The other way would be to just clone existing working instances with overlayfs.

Base lxc may be a bit of a pain. Look at lxd - I believe that makes things much much simpler.

Another thing about lxc is the unpriviledged container - which I think is great for security (not sure if docker provides this).

man lxc.conf ... this is your dockerfile equivalent.
