If you want Docker to work on Windows and WSL 2, installing Docker Desktop is most likely the way to go. For good reason, Debian uses the more modern nftables, but this means that Docker cannot automatically tweak the Linux firewall. Windows 11 Pro for Workstations: 6 TB. Hi Pawel, thank you for your feedback. Would you be interested in how to do same without so much trickery? so before that gets out of control: I'd like to share one that I did discover just this morning: devopstales.github.io/home/docker- it has lots of helpful information presented in a clear way, and the alternatives it lists don't require any "special magic" to get working, which might be very appealing for some. Probably not necessary, but on Ubuntu/Debian: Alpine (probably not necessary, but just in case): Alpine: Nothing needed. Is it known that BQP is not contained within NP?

INFO[2021-11-06T15:39:08.506977000+05:30] Starting up To run Linux containers on Windows there must be some kind of virtualization since containers use the kernel of the host operating system. anyways, with the deadline for this looming ever closer, I suspect there are going to be a sudden stupendous influx of "Docker alternative" and "Docker without Docker Desktop" articles, debates, and so on.. not unlike this one. 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. Do roots of these polynomials approach the negative of the Euler-Mascheroni constant? I got this so I just added "iptables": false to my daemon.json and this error was averted.

I have installed Rancher Desktop application on Windows 10 and set it to use docker as container runtime. Again, this step can be skipped if you opt against using a shared directory for the docker socket. Using Kolmogorov complexity to measure difficulty of problems? I have a Dockerfile that builds a Windows container with a development environment for the Nim programming language. However, if you would like to have the option of sharing the Docker socket system-wide, across WSL distributions, then all will need to share a common group ID for the group docker. (Will report back with results..). At this point if you run docker run hello-world:nanoserver as a non-privileged user, you will encounter the following error: One, to always use an elevated PowerShell to work with Docker.

I would suggest trying to modifying your run command with those paths, so something like: Make sure you pay attention to the slashes: in WSL you need a foreward slash (/) whereas windows does not really care.

What does not work is binding or mounting volumes to local directories, which used to work, when Docker Desktop was installed. Run Computer Management as an administrator and navigate to Local Users* and Groups > Groups > docker-users. But since I had no success, I went on. Another option may eventually be Rancher Desktop if they add Windows support, but it is currently limited to Linux containers. Looks too much tricky for me. If you dont want to switch between Windows and WSL when running Windows or Linux containers, you can just expose the Docker Daemon in WSL2 and create a context for it. As a next step we also would like to run them simultaneously. One for WSL and one for "Hyper-v and windows containers" which isn't clear if that is only for windows containers, but it reads sort of like it can do Linux as well. Contrary to what the length of this article might suggest, getting Docker working on WSL is fairly simple.
