WSL TERMINAL : docker-compose -f docker-compose.yml -f docker-compose.listener.yml up -d --build && docker attach listener Then, let's start an application on the host to handle HTTP message : Thanks for this post, very useful previously. The downside to this approach is that Docker static binaries on Windows do not support Linux containers, buildx, docker scan, or docker compose functionality. 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. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? with all that said: I do sincerely hope that anyone able and/or required to pay for a license actually does so it would be really sad for Docker to have come this far, having influenced so many aspects of "containerization", only to fade into the background because of "suddenly not being free to everybody".

When executing these lines you'll be prompted to enter your distro password (sudo) and I'll see after the log of dockerd. I love POSIX as well, but I don't have a choice. Yes ! Since I could resolve the name of the server from Debian WSL2 with no issue, I knew my DNS was working there. Get:1 deb.debian.org/debian stretch/main amd64 iptables amd64 1.6.0+snapshot20161117-6 [288 kB] If the result is "!" I even uninstalled and installed it back. I also tried the itzg/minecraft-server with the proper tags. For anyone struggling with using this behind a proxy, I found the only configuration file that dockerd looks at is /etc/environment, so set the likes of HTTP_PROXY, HTTPS_PROXY, and NO_PROXY in there before starting Docker. Do roots of these polynomials approach the negative of the Euler-Mascheroni constant? WSL + Docker without Desktop Communicate with Windows Host - Medium I realize that your post indicated to use iptables: false as a way to get debian wsl2 instances to work with docker. Try wsl wslpath from Powershell, or just wslpath from Linux, to see the options. 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. WARN[2021-11-06T15:39:10.294801200+05:30] Support for listening on TCP without authentication or explicit intent to run without authentication will be removed in the next release host="tcp://169.254.255.121:2375" There is some socket magic that I don't know by memory because I just keep the command in a gist. I suspect that most, however, will want to switch to iptables legacy.

Create Docker Windows Containers from Docker Desktop I was able to fix it with adding | head -n 1 at the end, so final command would look like: You need to escape the dot (.) Uninstall . I have based these instructions on those, with some tweaks learned from real world testing. If you obtained your Linux distro from the Store, you can likely skip this step, as the default user is already set up. I have written about getting Podman to work on WSL 2. Chances are, you already know these. Run your first Windows container | Microsoft Learn Connecting to any sort of enterprise-y VPN or WiFi just doesn't work. It just doesn't set the default links in the install process to be able to switch to the legacy rules. Markus Lippert It is the latest from Microsoft - or so I thought. Hey Derek, I believe the \mnt\wsl location is chosen so multiple Linux installations can share the same docker daemon. If you open Services, you should now see the Docker Engine listed: It will start automatically on Windows boot. But since I had no success, I went on. Then in the elevated PowerShell run: This will register the service, start it, and then exit the elevated Administrator shell. Maybe the project I'm trying to compile doesn't like Debian 9! A couple of updates when running in Windows 11H2 (and Ubuntu 22.04 in my case): 1) systemd is now native in Windows 11H2, BUT needs an updated WSL2 install (I was using WSL v0.63 and I believe native systemd support is in v0.68 onwards) - otherwise you get, Upgrading WSL to latest version means that updating /etc/wsl.conf with. But I was getting no rules generated by iptables-nft-save, and several rules generated by iptables-legacy-save, so I explicitly update-alternatives to iptables-legacy and rebooted (host and wsl2/debian). Please note that these steps require WSL 2 (not version 1). Unfortunately if you want to run docker from WSL (not using Docker Desktop) this will be the only way to use volumes. The flip side though is that if you are the type that prefers minimal command line interfaces then you can also install 'native' Linux Docker on WSL 2 without Docker Desktop and switch back and forth as needed. I agree it must be something in iptables too. failed to start daemon: Error initializing network controller: error obtaining controller instance: failed to create NAT chain DOCKER: iptables failed: iptables -t nat -N DOCKER: iptables v1.8.4 (legacy): can't initialize iptables table `nat': Table does not exist (do you need to insmod?)

If you want a more generalized "if this is wsl, then set the socket pro-actively" then you may prefer the following, which simply check for the existence of a /mnt/wsl directory and sets the docker socket if so: If configured as above, I recommend always running docker from wsl. Setting up Docker for Windows Containers manually is not really that hard to do. 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. At the moment I am stuck at step Launch dockerd and I get this error (image below). When I want to stay without Docker Desktop, I need the deamon inside wsl?
