For instance, you may want to create a script ~/bin/docker-service so that you can run docker-service only when you want, manually. I realize that your post indicated to use iptables: false as a way to get debian wsl2 instances to work with docker. big relief for me right there.. while this post does contain lots of super technical points (yeah, I saw those comments), this is a super technical topic.. which leads straight back to the "how" and "why" of Docker's decision on this matter. With Docker Desktop's WSL 2 backend, Docker integrates with Windows in a fairly elegant way, and the docker client can be launched from either Powershell or Linux.
