To do so, enter sudo visudo and add the following line (if your visudo uses vi or vim, then be sure to press "i" to begin editing, and hit ESC when done editing): Save and exit (":wq" if the editor is vi, or Ctrl-x if it is nano), and then you can test if sudo dockerd prompts for a password or not. There is some socket magic that I don't know by memory because I just keep the command in a gist. Using Kolmogorov complexity to measure difficulty of problems? In fact this is what Docker Desktop is doing, allowing all Windows native applications to use npipe docker context. Microsoft's has step-by-step instructions on how to upgrade to WSL 2.

WindowsDockerDev Container VS CodeRemote Development Windows. I honestly haven't tried this with older versions of Debian. sudo apt remove docker docker-engine docker.io containerd runc, curl -fsSL https://download.docker.com/linux/${ID}/gpg | sudo apt-key add -, echo "deb [arch=amd64] https://download.docker.com/linux/${ID} ${VERSION_CODENAME} stable" | sudo tee /etc/apt/sources.list.d/docker.list I have a Dockerfile that builds a Windows container with a development environment for the Nim programming language. I even removed and installed fresh wsl. Try the following to see if they are part of the sudo or wheel group: On distros that have a sudo group, such as Ubuntu and Debian, you should see something like sudo:x:27:myusername and on distros that have a wheel group, such as Fedora and Alpine, you should see something like wheel:27:myusername. My goal is to use the docker-cli in Windows (docker.exe), but using Linux containers, without the installation of Docker Desktop.

How can Docker Desktop mount Windows Volumes? See details regarding the companion Github repo by scrolling to the bottom. 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. You could also make a batch file with the appropriate command in it. To do so, we just need first to run a powershell script launching dockerd in WSL2 and once dockerd is listening we can simply use the command docker (maintained by Stefan Scherer). 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.

Here is what I get: $ update-alternatives --config iptables To run WSL 2, Windows version 1903 or higher is needed, with Build 18362 or higher. Contrary to what the length of this article might suggest, getting Docker working on WSL is fairly simple. Let's take an easy example: i would like to run some networking tool that scans my machine . Either Windows is remembering somewhere that it doesn't add the iptables-legacy rules, or I'm missing a package (or more than one) somewhere.
