MacOS Docker container

This makes it super simple to host your own OSX docker container for build/ci purposes.

Installation

You have to setup first an macOS installation (which is basically you going through the installer).

Note: Make sure KVM is enabled on your host.

docker build -t macos .
qemu-img create -f qcow2 ./macOS.img 35G
docker run -ti --rm --name macos --privileged -v `pwd`/macOS.img:/macOS.img --name macos -p 5900:5900 macos:latest install

Open now a VNC client and connect to localhost:5900. Go through the installer wizard.

Note1: Make sure to create a user with username macos and password macos. Note2: Make sure to enable "Remote Login": Settings > Share > Remote Login.

Usage

You can now start the container. This boots the macOS and allows you to connect to its SSH or VNC port.

docker run -ti --rm --name macos --privileged -v `pwd`/macOS.img:/macOS.img -p 5900:5900 -p 2222:22 -p 45454:45454 macos:latest

ssh server@localhost -p 2222

For macOS Host

If you use macOS as host you need to use a different docker-machine like virtualbox or VMWare Fusion with enabled VT-X support. Here is a tutorial on how to use an macOS guest inside docker of an macOS Host:

1. Install VMWare fusion
2. Create docker host: docker-machine create --driver vmwarefusion --vmwarefusion-cpu-count 8 --vmwarefusion-disk-size 40000 --vmwarefusion-memory-size 8000 default It might fail, but just continue:
3. docker-machine regenerate-certs --force default
4. docker-machine stop default
5. Open VMWare fusion and allow virtualisation in CPU settings of the default vm.
6. vmrun addSharedFolder vmrun list |grep default Users /Users
7. docker-machine start default
8. eval $(docker-machine env default)
9. Check if your new machine works: docker ps
10. Check if your new machine works: docker run -ti -v /Users:/Users alpine ls -al /Users. You should see your home folders.
11. Enable kvm: docker-machine ssh default sudo modprobe kvm_intel
