  help     print this help message
  build    build docker image, setup db
  start    run a built image as a daemon
  tail     run a built image with logging to stdout
  stop     stop a daemon
  restart  restart a daemon (= stop start)
  scrap    flush all related docker and db state
  reset    wipe the entire database but keep schema
  db       open a bash session in the db container
  rebuild  rebuild in case of schema changes (= scrap build)

  up       (= rebuild tail)
  down     (= scrap)
