Using arion and docker on the same host #121

Closed lunik1 closed 3 years ago

lunik1 commented 3 years ago

I have a machine with a mix of docker-compose and arion stacks. Previously this was not an issue as both used docker, but now that podman is required for NixOS-based containers I am not clear how to have both on the same host. I can't set virtualisation.docker.enable and virtualisation.podman.dockerSocket.enable. Will setting only the latter still allow my existing docker containers to function correctly?

Simultaneous Docker and Podman should run just fine.

If you still need docker as the backend for some containers, you can leave the default virtualisation.podman.dockerSocket.enable = false;. Then, for your arion-based projects you can then use environment variable DOCKER_HOST=unix:///run/podman/podman.sock to select Podman.

Seems to be working for me, thanks for the pointers!
