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..

Once unsuspended, _nicolas_louis_ will be able to comment and publish posts again. In all of the above, the principle is the same: you are launching Linux executables, using WSL interoperability. It requires a small proxy application to make it work though. Get rid of docker desktop. But let's continue magic ! First, let's pick one. While Docker Desktop on Windows can be run without having Administrator privileges, it does require them during installation. If you went with the default docker socket location of /var/run/docker.sock instead of the shared socket directory of /mnt/wsl/shared-docker as detailed above, then the script can be something like this: You may choose whatever location you would like for your docker logs, of course.
