TODO:

• replace @classpath_file with cp from libs/*.jar directory - more extensible for folks that want extra jars/plugins in derived images
  • or figure out a mount point for extra jars
• currently running as root!
  • maybe we need a base image with an ‘app’ or ‘java’ user preconfigured with rw permissions on /app
  • or do that in a launch.sh
    • this is a known and reasonable limitation of jib https://github.com/GoogleContainerTools/jib/issues/1029
