Each container group consists of a shell script at DIR/definitions/GROUP that
defines the group.
Documentation for groups may be stored in files in DIR/docs/GROUP/.
Source files for building images will be stored in DIR/build/IMAGE/.
Each group also has the following directories available for container volumes,
each with associated environment variables available in the definition script:

  DIR/volumes-config/GROUP/
      used for text-based configuration files, may be world-readable
      avoid placing secrets, keys or passwords here as this directory
      available as CONFIG_VOLUMES_DIR
  DIR/volumes-data/GROUP/
      directory where volumes that store data should be placed
      this directory should NOT be world-readable
      available as DATA_VOLUMES_DIR
  DIR/volumes-secret/GROUP/
      used for configuration files that include secrets, keys or passwords
      this directory should NOT be world-readable
      available as SECRET_VOLUMES_DIR

A shell script can be placed at '/etc/dock' which will be loaded on startup.
