Q: Are Rancher Desktop, Podman Desktop and Docker Desktop able to co-exist? I'm on Windows 11 + WSL2 (Ubuntu 22.04) with administrator access to my dev machine. Docker in WSL doesn't work at all. Podman sorta works. Rancher Kubernetes/k3s seems to just hang upon startup.

i have them both on the same machine and they can coexist. you just need to remember which one you are running so you don’t create issues. docker context helps with that, but nerdctl doesn’t

its not “supported” and if you try and brew install on mac it will bail because of the docker.sock possible collision, but you can manually traffic cop it pretty well

Right now I'm fighting with the fact that WSL2 doesn't have a systemd and apparently docker needs it. So what i'm hoping to accomplish is to have podman build

Dockerfile / Containerfile

s.. and play around with k8s manifests and helm.

well dockerd can get by without systemd (though it is coming soon) by using sudo and a script

vi ~/.profile
RUNNING=`ps aux | grep dockerd | grep -v grep`
if [ -z "$RUNNING" ]; then
    sudo dockerd > /dev/null 2>&1 &
    disown
fi

Docker Desktop and Rancher Desktop do much of the same thing by using init scripts to get things going

Thank you . I'll give it a shot! However I want to eventually be able to move beyond docker and practice k3s/k8s. so hence going fwd I would want to have rancher desktop. (containerd engine, if that matters)

yup and it should work. If you need a proxy in WSL2 well that might be more of an issue

how so? i honestly wanted to live in WSL2, because all of the scripting (bash) and coding (vscode) was going to be there.

proxy support in RD is a work in progress. Because WSL2 is a shared routing stack i have seen lots of issues with starting k3s w a proxy as the cluster traffic tries to egress

and as WSL2 network is dynamic doing a no_proxy is not trivial
