While there is a docker version for windows (server I believe) the last time I checked it could only run windows containers (so basically none). The Linux support never got out of beta. I think now they are just saying use windows subsystem for Linux (WSL) for that.
I have been quite happy with docker on a Linux virtual machine hosted on a windows server (I know not the "normal" way to do it but since I am a windows Server admin at work it worked best for me).
The reason that you cannot run Linux containers on windows by default is that docker is no full fledged virtualization Software it sill uses the kernel of the host system. And a Linux container needs a Linux host system.
Here is a forum thread from the docker forum. You might find some valuable insights there: https://forums.docker.com/t/docker-run-linux-container-in-windows-2019/128196
WSL2 is Linux on a virtual machine. Docker for Windows is running in a VM.
I'm also a weirdo though, I'm using podman instead (and may switch to nerdctl).
I think there are two "Docker for Windows" one is docker desktop used on windows client OS where you can switch between windows and linux containers. This is the one where it runs a VM for the Linux containers but it's designed for development and not so much for hosting (at least I have not get it to work for this)
And there is the docker that's included in Windows Server wich can only run windows containers but those natively and suitable for hosting dotnet web services on scale.
Never hears of nerdctl. What is the feature that would make it better than podman for you?
I using and deploying to kubernetes. Nerdctl has a docker API but it's completely backed by k8s. So, for regular dev I'd just need a k8s cluster and not k8s + something else to build the images and push them into the k8s image repository.
