Hi guys, I was running rancher desktop using

containerd

/

nerdctl

successfully, now I switched to `moby`/`docker` and my mount (bind) are failing. (win11 / WSL2 / rancher desktop 1.4.1). I read a lot a related issues about that but cannot find a workaround does anyone have a lead for me ? To reproduce :

docker run --mount type=bind,source=/etc/passwd,target=/etc/passwd --rm ubuntu:20.04

Returns:

docker: Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error mounting "/mnt/wsl/rancher-desktop/run/docker-mounts/6b17adac-3323-46ab-933a-202faa10537a" to rootfs at "/etc/passwd": mount /mnt/wsl/rancher-desktop/run/docker-mounts/6b17adac-3323-46ab-933a-202faa10537a:/etc/passwd (via /proc/self/fd/6), flags: 0x5001: not a directory: unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type.

Did you verify

/etc/passwd

is a file on both your laptop and in the container?

Definity existing on both sides.

I have a feeling I remember reading in this Slack channel that only folders in $HOME could be mounted as volumes. Or maybe $HOME and a few other locations. I can't remember exactly...

This is really not that clear. Anyway managed my way around to run stuff a normal user in container without the need to mount

passwd

and

groups

files. Thank anyway !

https://docs.rancherdesktop.io/faq/#q-does-file-sharing-work-similarly-to-docker-desktop-d[…]do-any-additional-configuration-to-mount-volumes-to-vms

Currently, the following directories are shared by default:

/Users/$USER

on macOS,

/home/$USER

on Linux, and

/tmp/rancher-desktop

on both. For Windows, all files are automatically shared via WSL2.

Nice ! Thanks.

Using a wsl2 setup as well but for some reason it mounts Paths /mnt/wsl/rancher-desktop/run/docker-mounts/ instead of natively within wsl. Is there a fix for this? Works first container run but after running it again after a restart causes same issue

It needs the funny mount because WSL2 uses containers for different distros, and that's how we can share things across. We basically have to end up bind-mounting your mount source into the shared area, and then get dockerd to bind-mount it again into the container. It sounds like there's an issue with files though (which I thought we had fixed at some point); will need to take a look again. (But it's probably the same as #2461)

Cool, ill have a look and this is a way of recreating it, if it helps, by running it, stopping and re-running it which gives the error. Noticed when you try and bind things below it gets confused second time round

- /etc/localtime:/etc/localtime:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
