I’m thinking we could call this PREK_CONTAINER_RUNTIME. By default, prek would automatically try whatever’s available—docker, podman, etc. But you could override that with PREK_CONTAINER_RUNTIME if you want to force a specific one. Like, set it to docker to only use docker, or podman to only use podman. What do you think?

[st1971]

That makes sense to me, happy to make that change later today 👍

[st1971]

Have updated as suggested, hope it looks ok :-)

[j178]

Thank you!

[st1971]

No problem, should be thanking you for the goodness knows how many hours you have spent on this :-)
