helm/Dockerfile

#!/usr/bin/docker
#
# This Dockerfile is to be consumed with the docker_osx helm templates. It consumes the
#  Ubuntu image so that OpenCore.qcow2 can be re-generated (which happens in Kube itself),
#  not to mention that OSX-KVM was written for Ubuntu. This was not designed to be run in Docker
#  by itself.. very well anyway.

# this installs the kvm linux kernel in the docker container so that OpenCore.qcow2 boot images
#  can be built.
