# for a more release-y image, this would be the right way to go. But it does slow down development
# so I copy just what is required for the build commands
# COPY . /task-tracker

# TODO consider how much of this could be run on a different / dedicated container
# Later symlink /tmp/node_packages to wherever they are needed
# TODO How would I mount a volume to contain the download caches for yarn / pip to speed up image creation?
# TODO consider how I would update the lock file? Some clever use of docker cp perhaps?
