Podman definitely isn't a drop in replacement, it's like 90% there.
whats the last 10%?
From my experience, a bit of systemd config.
Serious question: why change? Doesn't docker do the job (isn't it FOSS)?
I’ll consider it a drop-in replacement when Kubernetes can use it.
Not sure what you mean, Podman isn’t a container runtime and Kubernetes has deprecated it’s docker shim anyway.
Its* docker shim
lol you’re not wrong but was it worth saying?
Kubernetes uses cri-o nowadays. If you're using kubernetes with the intent of exposing your docker sockets to your workloads, that's just asking for all sorts of fun, hard to debug trouble. It's best to not tie yourself to your k8s clusters underlying implementation, you just get a lot more portability since most cloud providers won't even let you do that if you're managed.
If you want something more akin to how kubernetes does it, there's always nerdctl on top of the containerd interface. However nerdctl isn't really intended to be used as anything other than a debug tool for the containerd maintainers.
Not to mention podman can just launch kubernetes workloads locally a.la. docker compose now.
