  # And, it doesn't seem that you can forward the version tag in the docker run command to the 'parent' image.
  # So, it seems we're stuck creating a bunch of images whose only difference is the version tag in the FROM statement at build time.
  # Or, using the base images, which don't have SSL or logging enabled.
