Can I change the kernel used in Docker for Windows?

Question

I want to run a set of docker containers but with a custom kernel.

Since Docker for Windows is already using Hyper-V, could it be possible to change which image is running?

Answer 1

Docker uses its own patched Kernel (along with a specialized Linux distro) called linuxkit in Docker Desktop. It is mentioned in https://hub.docker.com/r/docker/for-desktop-kernel.

I am able to find kernel, initrd.img and cmdline in a folder called linuxkit inside the application folder of my Docker for Mac installation.

I assume that you will find a similar folder inside the Windows installation.

Simply build your own Kernel with the instructions/patches of linuxkit and replace those files.
