Updated April 10, 2022, with current Alpine instructions, Debian/Ubuntu package signing tweaks (no more apt-key), and better guidance for handling iptables in Debian. A little more suggestion about TCP access, as well. And further emphasis on the optional nature of the
/mnt/wsl/shared-dockersocket directory.
Once upon a time, the Windows command line was CMD, and it was horrible. No longer.
Collect them all! Install Winget, Chocolatey and Scoop. (I just put the “vs.” in there as clickbait.) They make installing and managing software on Windows so much easier. They are different tools, though, and I suggest that their usage depends on the scenario.
Using Windows Subsystem for Linux (WSL), we have a choice of Linux distributions available in the Windows Store, such as Ubuntu, Kali, Debian, etc.
With Windows Subsystem for Linux (WSL) version 2, running Linux containers is possible and easy. However, Docker does not work without the docker daemon running, systemd is usually used to govern this, and WSL typically does not have systemd running.
