Thanks for this post, very useful previously. Success? If the above script is placed in .bashrc (most Linux distros) or .profile (distros like Alpine that have Ash/Dash as the default shell), or other shell init script, then it has an unfortunate side effect: you will likely be prompted for a password most every time a new terminal window is launched. This article attempts to explore such a process and options along the way. However I agree developing linux apps with docker on windows can be a pain I'd recommend just installing linux on a dedicated machine for that purpose if you can. You simply package each application into a container and run it. Setting up Docker for Windows Containers manually is not really that hard to do. In all of the above, the principle is the same: you are launching Linux executables, using WSL interoperability. Yes.

Then in the elevated PowerShell run: This will register the service, start it, and then exit the elevated Administrator shell. Given this, you probably want to configure Debian to use the legacy iptables by default: If you are comfortable, instead, with nftables and want to configure nftables manually for Docker, then go for it. Exactly, this is very unfortunate but currently only linux has a standalone daemon, Windows and MacOS have to install Docker Desktop to get a native daemon. It just isn't setting up the legacy rules. For peace of mind, you can double-check: something like sudo -k ls -a /root should still require a password, unless the password has been entered recently. I removed the Debian WSL for now. If you do not yet have a running WSL instance with a distro of your choice, the next step is to pick one from the Microsoft Store. Success. I have based these instructions on those, with some tweaks learned from real world testing. For instance, you may want to create a script ~/bin/docker-service so that you can run docker-service only when you want, manually. In WSL2, it's not possible to assign IP address but, I can use the windows port forwarding to redirect a local port from the host to a specific one of my distribution.

Jonathan, thank you for the incredibly detailed description of setting up Docker for use in WSL2 without Desktop. After this operation, 0 B of additional disk space will be used. Visual Studio Code - Code Editing. I have tried with multiple laptops (and multiple distros) and even with so many customisations, laptops keep heating up on idle. ibb.co/yQGVZ18 Other editions have even higher limits.
