I've played around with setting DNS in the container explicitly using the /etc/docker/daemon.json with things like "dns": ["1.1.1.1", "8.8.8.8"], but if the container can't even get connectivity to these ips that's not going to work.. My Debian environment does not have any iptables configured. I had in mind to make my existing toolchains still working (VSCode, Visual Studio). The issue is more easily reproduced on my system by just running ping commands inside the latest alpine image: The problem was that even though I had reverted to iptables-legacy in Debian, I still had iptables: "false" in my docker daemon.json. I mainly followed these instructions to install Ubuntu 20.04-LTS using WSL2 and prepare everything that dockerd is running inside this instance.

Brilliant article - thanks for the thorough write up @bowmanjd! EDIT: It turned out that the eventual root cause of my issue was that my distribution was still on WSL1. What is the significance of \mnt\wsl? If it returns "Yes, that ID is free" then you are good to go, with the following: Or, if groupmod is available (which it is on Fedora, Ubuntu, and Debian, but not Alpine unless you sudo apk add shadow), this is safer: Once the group id has been changed, close the terminal window and re-launch your WSL distro. I even removed and installed fresh wsl. I'll share later in a response to this comment. I have based these instructions on those, with some tweaks learned from real world testing.

Looks too much tricky for me. When did this happen? To do so, we just need first to run a powershell script launching dockerd in WSL2 and once dockerd is listening we can simply use the command docker (maintained by Stefan Scherer). Thanks for the help. If you don't want to rely on a particular WSL shell script, you could implement a Powershell function to launch dockerd, such as this: This function takes one parameter: the distro name. Strange my Debian is so far behind. Windows 11 Enterprise: 6 TB. Isn't the deamon running inside wsl in any case? Before we mosey along, though: are you aware of Podman? It's a peaceful symbiosis.
