A comment on Podman: A Daemonless Container Engine.

It is almost 100% compatible with docker. I only had to do minimal changes in my Dockerfiles to use it.

But not Buildkit and docker-compose.

Podman v3 is compatible with docker-compose (but not yet swarm mode, FWIU), has a socket and a daemon that services it.

Buildah (`podman buildx`, `buildah bud --arch arm64`) just gained multiarch build support; so also building arm64 containers from the same Dockerfile is easy now. https://github.com/containers/buildah/issues/1590

IDK what BuildKit features should be added to Buildah, too?

Cache mounts are what we rely on for incremental rebuilds.
