Docker keeps a history of changes to the container with layers, and you might arguably treat it like version control.

maybe "docker history" ~ "git log"?? tags=branches?

Docker isn't one thing, so it's ALL grey. It's not really make. It's not really a vm. It's not really even reproducible.

One thing is for certain - it's hard to describe docker to new folks so they get it. "it's sort of like netflix, for cows, but in space..."

That's the most insane use of Docker I've ever heard of.

I'm not saying people use it for vc, it's how docker works. It optimizes your containers using layers and if you do "FROM ubuntu:18.04" in 3 dockerfiles, you only have one copy of the ubuntu stuff.
