# The bootstrap process uses docker to build ghc from a debian glibc host
# then upload the bootstrap compiler to where that source url is.
#
# Ensure that docker is running prior to calling this.
#
# Note, these docker images are large, ~10G the dockerfiles weren't built
# to be small. Once built the containers should likely be removed.
