Yes, I have docker as an alias to root podman and VS Code is able to build a devcontainer with it. Rootless also works but was a lot slower for me. There are a couple of minor incompatibilities I've noticed in other areas:
* Podman doesn't have a unix socket like /var/run/docker.sock but it can be set up with podman-system-service if needed.
* Some applications check if /.dockerenv exists. They shouldn't, but you can just touch a file there to work around it.
