Do you mean rootless from the stance of the host or inside the Docker container? K3D installs K3S (as root) inside a Docker container but from the host stance as long as you're in the docker group you can use it. K3S doesn't use Docker for a native install as I recall, so I'm assuming you meant K3S inside a Docker container.

I'm referring to rootless from the host. As in running rootless and passing the

--docker

flag. I've tried the

--docker

flag on a rootless install but it has issues and I haven't been able to figure out why. Since it's experimental I'm kind of assuming it doesn't work

I assume the user you're running as is in the docker group? If K3D (which has their own channel here too) doesn't solve what you need, I can't say I know anything to help past basic debugging. I've never used K3S native and wasn't even aware it'd run on Docker.

I'm more experimenting right now to see what's possible and I'm not particularly interested in K3D for what I'm doing now. Thank you for the help though!

Is there a reason you need Docker? Kubernetes itself has gone away from Docker, so to some extent any Kubernetes distro with Docker will be at least a little awkward. I think I'd probably try with the normal containerd/crio and see if I could get what I need from ctr/crictl/nerdctl . If I recall correctly these RKE2 commands from https://gist.github.com/superseb/3b78f47989e0dbc1295486c186e944bf could be tweaked for K3S, and I've got this K3S etcd commands link ( https://gist.github.com/superseb/0c06164eef5a097c66e810fe91a9d408 ) bookmarked too, though I don't remember what was there.
