# 
# This Dockerfile automates the installation of Docker-OSX
# It will build a 200GB container. You can change the size using build arguments.
# This Dockerfile builds on top of the work done by Dhiru Kholia, and many others.
#       
# Build:
#
#       docker build -t docker-osx .
#       docker build -t docker-osx --build-arg VERSION=10.15.5 --build-arg SIZE=200G .
#       
# Basic Run:
#       
#       docker run --device /dev/kvm --device /dev/snd -v /tmp/.X11-unix:/tmp/.X11-unix -e "DISPLAY=${DISPLAY:-:0.0}" sickcodes/docker-osx:latest
#
#
# Run with SSH:
# 
# 
#       docker run --device /dev/kvm --device /dev/snd -e RAM=6 -p 50922:10022 -v /tmp/.X11-unix:/tmp/.X11-unix -e "DISPLAY=${DISPLAY:-:0.0}" sickcodes/docker-osx:latest
#       # ssh fullname@localhost -p 50922
# 
# Optargs:
#       
#       SIZE=200G
#       VERSION=10.15.6
#       ENV RAM=5
#       ENV SMP=4
#       ENV CORES=4
#       ENV EXTRA=
#       ENV INTERNAL_SSH_PORT=10022
#
# Extra QEMU args:
#
#       docker run ... -e EXTRA="-usb -device usb-host,hostbus=1,hostaddr=8" ...
#       # you will also need to pass the device to the container
#
