How to access the volume of a Docker Desktop app from Windows WSL2 bash? I can see the \\wsl.localhost\docker-desktop-data\version-pack-data\community\docker\volumes just right from Windows Explorer, but from WSL2 bash this folder /mnt/wsl/docker-desktop-data/version-pack-data listing results in an empty set.

I'm using Windows 11 Pro Version 10.0.22000 Build 22000

Slightly older question dusted off by @ADJenks' answer, which certainly will work.

But IMHO a better solution is the one I detail in this answer. Since that's a fairly long read, I'll repeat it here. From inside a WSL2 distribution:

$ findmnt -a | grep "version-pack-data\s"
| |-/mnt/wsl/docker-desktop-data/version-pack-data        /dev/sdf[/version-pack-data]          ext4          rw,relatime,discard,errors=remount-ro,data=ordered
# Using the block device returned (sdf in this case):
$ sudo mount /dev/sdf /mnt/wsl/instances/docker-desktop-data -o X-mount.mkdir
$ cd /mnt/wsl/instances/docker-desktop-data

The advantage here is that you will be using the native Ext4 filesystem. Using drvfs will not provide native permissions, symlinks, and other POSIX features.

For some reason, you have to re-mount it on a different path like this:

  1. In powershell:
net use h: \\wsl$\docker-desktop-data
  1. In wsl:
sudo mkdir /mnt/yourdockermount
sudo mount -t drvfs h: /mnt/yourdockermount

The above worked for me. It was also suggested to do it in one step like so:

In wsl: sudo mount -t drvfs '\\wsl$\docker-desktop-data' /mnt/yourdockermount
