Is it possible to get macOS running in a Docker container?

I know that it's possible to get macOS running in a VM under Parallels, VirtualBox and VMWare Fusion. I have containers with Windows and many distributions of Linux and BSD Unix. I'm hoping somebody has managed to get macOS running in a container.

Yes you can run macOS in a Docker Container: https://github.com/sickcodes/Docker-OSX

It has very low overheads because it's all real KVM nested virtualization.

I have stress tested it and the minimum requirements is about 2.5GB of RAM per container. The Docker container is Arch but it has very low overheads.

Make your own container:

# Catalina
docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    sickcodes/docker-osx:latest

# Big Sur
docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    sickcodes/docker-osx:big-sur

Or if you want to fast-track, or use CLI only, you can boot straight into a real headless MacOS command line using :auto

docker run -it \
    --device /dev/kvm \
    sickcodes/docker-osx:auto

You'll drop into the Darwin shell.

Extra options:

Visual display:

    -e "DISPLAY=${DISPLAY:-:0.0}" \
    -v /tmp/.X11-unix:/tmp/.X11-unix \

Add SSH:

    -p 50922:10022 \

Change resolution

    -e GENERATE_UNIQUE=true \
    -e WIDTH=800 \
    -e HEIGHT=600 \

This looks promising! I will try to get it to work.
