Maybe some tooling you use can't handle Podman, or you just want to put WSL through its paces. In the original post it says you only need to do this for Debian but not Ubuntu, and I'm using Ubuntu so I skipped that step originally. Updated April 10, 2022, with current Alpine instructions, Debian/Ubuntu package signing tweaks (no more apt-key), and better guidance for handling iptables in Debian. Posted on Feb 14, 2021 Hey Derek, I believe the \mnt\wsl location is chosen so multiple Linux installations can share the same docker daemon. I agree it must be something in iptables too. If unsure of the name, simply run wsl -l -q from Powershell to see your list of WSL distributions. macOS is expensive to buy (yet mainstream), as well as forced obsolescence (via OS updates + requirement, and repair / replacement prevention); not to mention keyboard layout confusion (which is "cost to change"). But in the end, turned out it was required. You can follow the directions there in order to correct DNS, but of course eliminate any occurrence of sudo in those commands, as you do not have it yet, and you should still be root anyway. For instance, install and configure Fedora, or any other distro for which you can obtain a rootfs in tar format and then wsl --import rootfs.tar.

The Docker engine includes tools that automate container image creation. Then this issue just went away, regardless of whether I ran WSL as admin. It's a peaceful symbiosis. However, if you would like to have the option of sharing the Docker socket system-wide, across WSL distributions, then all will need to share a common group ID for the group docker. This will set the default version to WSL 2, or fail if you are still on the first version. Success. For communication over the socket, privileged access is required.

You just install it as any other applications for Windows, selecting dockerd as container runtime. So the reason I use Windows is because that's where the driver support is.
