#2Most of my containers end up on k8s clusters as pods. What else would one use podman or docker for beyond local dev or maybe running a local containerized service?

For a while we used it for scalable preview environments: specify the branch, hit deploy, and have a QA-able environment, with full database (anonymized) ready to go in 15 minutes (DB was time bottleneck).
We ditched it for EC2s which were faster and more reliable while being cheaper, but that's beside the point.
Locally I use OrbStack by the way, much less intrusive than Docker Desktop.

#4Both podman and docker have pretty poor error handling in my experience.
It depends on the error, but for me it often comes down to a docker compose misconfiguration, resource, permissions, etc. In docker always find the errors quite difficult to trace back to root cause.
In podman you get a python a stack trace.
I wish both projects would assert different assumptions/requirements at runtime and report errors/warnings in a human-readable way.

#5The "podman generate systemd" command from the article is deprecated. The alternative are Podman Quadlets, which are similar to (docker-)compose.yaml, but defined in systemd unit files.

#6I would love to love Podman, but the fact that it regularly just fails to work on my Windows laptop (the WSL2 instance seems fine, but can't be connected to, the UI just says 'starting', and none of the menu options do anything) and that I can't figure out how to make IPv6 networking work on any platform means that Docker isn't going anywhere for the foreseeable future, I'm afraid...

#7Last third party container I’ve built had COPY —-link statements that didn’t worked on podman. Granted it worked just fine with a normal copy but it’s not 1:1.

#8I have ditched docker desktop on macOS for OrbStack.

EC2 and containers are orthogonal technologies, though.
Containers are the packaging format, EC2 is the infrastructure. (docker, crio, podman, kata, etc are the runtime)
When deploying on EC2, you still need to deploy your software, and when using containers you still need somewhere to deploy to.

#10I really wish Docker didn't take over the industry like it has. In my experience not enough people know how to debug yet another layer of abstraction.
Remove layers, keep things simple.
That being said, it is here to stay. So any alternative tooling that forces Docker to get it's act together is welcome.
