      start
        ENVIRONMENT
          local | full | ll (default: local)  Indicate which environment to develop against
              (ll: local_lean to run local with the absolute minimal support to run hmiServer for development)

        run (default: null) Indicate whether to run the server after starting the containers

      stop
        ENVIRONMENT
          local | full | ll (default: local)  Indicate which containers to stop

      OTHER COMMANDS:
        encrypt
          Encrypts the secrets file
        decrypt
          Decrypts the secrets file
        docker-compose
          Generates a combined single docker-compose.yml file for local development
