That's exactly what I have been saying, though. Prior to Docker, there was nothing like Dockerfiles or OCI images. The closest thing I can think of was Vagrant, but it's missing a lot of what makes Docker good.

The reason why containers are good is entirely about the concepts, NOT the actual engine or technologies. Again, you can literally run OCI images in a virtual machine; Ignite will run them in a KVM. That's as literal as you can get.

Docker existed and did a lot of the same things it does today in 2013.

FreBSD jails predate containers, same idea. https://en.wikipedia.org/wiki/FreeBSD_jail

The ONLY thing docker did was make a small amount of questionable UX around the low-level container primitives. They did not invent anything, definitely not containers. I could share VM images before Docker, nothing new there... the concepts all existed before containers.

You can literally run... anything... on a VM, why make a point about being able to run OCI images? This is like a no-op.
