While I understand the phrasing, it's still funny to read "open-source Docker replacement".

Somehow a lot of these blog posts seem to get the fine technical details of the marketing speak wrong.

> Docker recently changed the license

From my understanding this is related to Docker Desktop not Docker. I'm pretty sure Podman can't replace Docker Desktop. This is also what the linked website says.

Or did I miss something?

And in the linked Blog post it says

> Docker was dropped from Kubernetes.

which from my understanding is also incorrect, because it's the docker-shim which is deprecated (not dropped) and Docker inc could probably make Docker Engine CRI compliant.

It seems to me that almost no one understands the difference between the various layers of "Docker" (that is to say: Desktop, CLI, daemon, containerd, runc) and which layers tools like Podman aim to replace.

To be fair, podman has it's own "Docker Desktop" part, podman machine. But of course on Linux this doesn't make any sense.

Podman can replace docker desktop. It doesn't have the same GUI but it does have the capability to run containers via familiar CLI commands on a variety of OSes, connecting to (and in some cases provisioning through podman machine) a VM when required

I also think that it's more than safe to say that K8s is dropping Docker when they've deprecated it as a container runtime

It depends on what you mean by “replace” Docker Desktop, but Podman can run a VM on macOS and has replaced Docker Desktop for me. There’s no fancy (useless) UI nor Windows support yet though.

Im just wondering if the full loop will ever be complete and deployment patterns start shifting to single file compiled executables.

Windows works via a "Bring your own VM" approach, but since WSL exists I'd expect most Windows users would just run it there
