Podman runtime support?

[anarchy89]

Description

I saw that there were plans for podman runtime support. any updates on this?

[abiosoft]

Tbh, it is not yet prioritized because there is little to no demand for podman runtime.

[andrewcrook]

Isn't it compatible with podman's docker interface?

[andrewcrook]

tbh, I thought demand in podman would have increased since dockers new licensing rules.

@andrewcrook Docker's licensing rules are about Docker Desktop, not the open-source docker-ce. So all linux uses, including Colima's usage, are open-source and not related to that. There has been massive movement to Colima as opposed to Docker Desktop.

And no, podman is absolutely not a drop-in replacement for Docker.

[andrewcrook]

all linux uses

@rfay not on Linux though and as per installation instruction 'brew install docker’ is docker for desktop not docker-ce

And no, podman is absolutely not a drop-in replacement for Docker.

I didn't say it was. but I have had successes with using the docker interface to work with several tools, so just wondered.

Question is, is there an open source solution that can be used for macOS?

@andrewcrook the brew package is only the docker cli built from source (https://github.com/docker/cli) which is OSS.

So brew install docker is not same as using the proprietary docker desktop.

[andrewcrook]

@abiosoft I stand corrected brew install docker --formula is cli and brew install docker --cask is docker for desktop thanks for the info I have been looking for docker-ce for macOS and couldn't find it. I thought I used brew install docker to install Docker for Desktop Mac ages ago. then I remember I actually beta tested Desktop for Mac so installed it via DMG

FWIW, you can also brew install podman: https://formulae.brew.sh/formula/podman

And it can also run a Linux VM podman machine init --help (caveat it doesn't look like you can run an x86 VM, unless maybe you install podman with x86 brew, unlike colima which can run multi-arch from the same install)

@AngusP

Yeah, that’s how I installed it.
I originally thought colima used lima, which supports Podman, in a way that perhaps it would gain its support that way.
