Get:1 deb.debian.org/debian stretch/main amd64 iptables amd64 1.6.0+snapshot20161117-6 [288 kB] We can continue to develop with containers without Docker Workstation. Once unpublished, this post will become invisible to the public and only accessible to Nicolas Louis. Before you can install Docker you need to enable systemd. Docker Desktop delivers the speed, choice and security you need for designing and delivering these containerized applications on your desktop. I did "sudo apt-get install iptables" to be sure.

Never miss out on developer content you need to maintain a healthy developer career. I'll never understand why developers who write code to run in linux fight with windows. If your username is missing from the group, take note of the group name (sudo or wheel) and add the user in question to that group: Finally, as root, make sure that the admin group (whether sudo or wheel) is enabled for sudo: If the line is there, but commented out with a #, then run visudo then make sure the line reads thus (use wheel or sudo as determined earlier): Once these steps are complete, test again with: If you are prompted for the password, then all is well. ){3}[0-9]{1,3}" | grep -v 127.0.0.1 | awk '{ print $2 }' | cut -f2 -d: The error is: failed to start daemon: pid file found, ensure docker is not running or delete /var/run/docker.pid This is a very useful tool, to say the least. ){3}[0-9]{1,3}" | grep -v 127.0.0.1 |awk '{ print $2 }' | cut -f2 -d:`, And you get the IP address, as described before, In the Powershell windows of the terminal, you can run the following command Installing WSL is explained here or you can use an already existing Ubuntu distribution.

In parallel, in a windows terminal opened in my distro, I can check with top or htop if dockerd processes are running. Thanks for the help. On your windows, you need to install a couple of things : (Inspired from the Jonathan Bowman's article), Check if sudo is installed if not : *apt install sudo*`, You would see something like sudo: x:27:myusername, Otherwise, We use usermod to add an user to the sudoer group.

Pretty sure there is no legacy version because iptables wasn't legacy then. I reinstalled the Debian WSL. If and only if you opted to use the shared docker socket in /mnt/wsl/shared-docker as detailed above, first set the DOCKER_HOST environment variable: You should see the "Hello from Docker!" On later versions of Alpine from the Microsoft Store, while a non-root user is created as part of setup, this user is initially password-less. Jonathan, thank you for the incredibly detailed description of setting up Docker for use in WSL2 without Desktop. at the end of the day, everybody still has bills to pay.. . Sometimes, one just needs Docker to work.

I don't care whether it's the fault of F5 or the community for not working -- if I can't VPN in, I can't work. And that's all! Docker Desktop is not the core technology that runs containers, it only aims to make it easier to develop software on Windows/macOS that runs in containers. Rather than twist things to use the existing init system, we just launch dockerd directly: There should be several lines of info, warnings related to cgroup blkio, and the like, with something like API listen on /mnt/wsl/shared-docker/docker.sock at the end.
