alt Hacker NewsI keep reading comments by podman fans asking to drop Docker and yet every time I have tried to use podman it failed on me miserably. IMHO it would be better if podman was not designed and sold as a docker drop in replacement but its own thing.

That sucks, I never had any problem running a Dockerfile in podman. I don't know what I do differently, but I would as a principle filter out any container that messes with stuff like docker in docker. Podman doesn't need these kind of shenegians.
Also the Docker Compose tool is a well-know exception to the compatibility story. (There is some unofficial podman compose tool, but that is not feature complete and quadlets are better anyway.)
I agree with approaching podman as its own thing though. Yes, you can build a Dockerfile, but buildah lets you build an efficient OCI image from scratch without needing root. For those interested, this document¹ explains how buildah compares to podman and docker.
