“Windows 上的 Docker”是否启动 linux 虚拟机？

Question

I'm aware that the old Docker Toolbox uses VirtualBox to run a minimal linux virtual machine for Docker using boot2docker which is a minimal light-weight Linux OS. Now, with the new Docker on Windows they claim that they use HyperVisor on Windows 10 Pro directly.

Does this mean the Docker on Windows package got rid of the Linux virtual machine totally, or is there still a Linux virtual machine being used on Windows?

Answer 1

Not Really.. It uses a VM on the Hyper-V they call it MobyLinuxVM

It uses an Alpine boot image which has Hyper-V Integration Services which allows communication between the Hyper-V Host and the Linux Guest (ie to retrieve the Guest IP and send two-way messages )

Answer 2

A container is considered “native”, if it can run directly on the host operating system.

Linux Container - A Linux application that runs in an isolated Linux environment. This same container can be run on a Windows OS using virtualization to emulate a Linux environment, but the container is still running on Linux.

Windows (Server) Container - A Windows application that runs in an isolated Windows environment.

Docker on Windows to run a Linux container requires virtualization. The available options are:
VirtualBox (Docker Toolbox)
Hyper-V backend (Docker Desktop)
WSL2 backend (Docker Desktop)

The Container (and Docker ) terminology is very confusing, especially with Windows nuances. See Docker Container in Linux and Windows for an overview with many useful reference links.
