How to Replace Docker with Podman on a Mac

Is there any practical benefit of Podman over Docker on a Mac? Virtual machine is still needed, so any performance issues are likely to persist (well, maybe Docker for Mac is a bit more buggy, but we can manually setup Docker instead of Podman in a similar way). Also, I think we are losing here access to the Docker socket on the host (inside the virtual machine it can be emulated using docker-podman).

Podman does have a socket that can be started. I use it on Linux so I'm not sure how that works on MacOS but it's API is Docker compatible, thus works with the docker cli and docker-compose as well.

  # Get URI
  > podman system connection ls

  # Create tunnel
  > ssh -nNT -L/tmp/podman.sock:/run/user/1000/podman/podman.sock -i ~/.ssh/podman-machine-default ssh://core@localhost:[PORT]

  # Export socket location
  > export DOCKER_HOST='/tmp/podman.sock'

podman has no revenue model, it is an open source project managed by https://github.com/containers

So without a revenue model, how would they pay someone to maintain it if the current maintainer[s] need to focus on family or paying their mortgage?

When I last looked into it, I came away with the feeling that github.com/containers is pretty much RedHat without any official backing.

That’s how Red Hat operates mostly. Time will tell if IBM royally messes this up but Red Hat is an upstream first company. If they need something they will put up the developer time but it will be a community project first that they repackage for RHEL. Red Hat’s secret sauce so to speak is the stupid amount of ongoing work it takes to actually maintain a distro, not the software itself.

My understanding is that this old article is no longer the simplest/easiest way of doing this. For that, see https://marcusnoble.co.uk/2021-09-01-migrating-from-docker-t... . tl;dr: $ brew install podman $ podman machine init $ podman machine start $ alias docker=podman If you're on an M1 you may run into https://github.com/containers/podman/issues/10577 (which is WIP, and may have been resolved by https://github.com…

Does this actually work for you? I tried it and networking was broken out of the box – it couldn’t even pull a container image. I didn’t have time to spend digging into it, however, and would not rule out that being an artifact of our VPN.
