Note that Docker Desktop for Mac has always used a VM to run a Linux instance. Same with Docker Desktop on Windows (I don't know if this has changed with WSL).

Note that Docker Desktop for Mac has always used a VM to run a Linux instance. Same with Docker Desktop on Windows (I don't know if this has changed with WSL). The main difference on M1 Macs is the qemu emulation when a Docker image is only available as x86_64. If the image is available in AArch64 it runs native on the M1.

> Same with Docker Desktop on Windows (I don't know if this has changed with WSL). Not really. On Windows you can choose if you want to run Linux binaries in a VM or native Windows containers.

  I feel Windows Containers are a whole separate thing. I personally have never seen anyone use them, but then again I have never worked on a Windows Server stack.

  Native Windows Containers run Native Windows Binaries. You can't just launch your Linux docker containers using Native Windows Containers.

WSL1 doesn't support cgroups and other pieces needed to run containers, but Docker Desktop can use WSL2, which uses a lightweight VM in the background, so you are correct.

Oh yeah, I thought the whole VM thing was implied with the fact that Docker is a Linux technology...
