   docker build -t rbs_image_script  .

9)docker-compose up(go to docker-compose.yml)

  docker-compose up -d

 docker-compose exec rbs_image_script  bash

11)save docker

docker save rbs_image_script  > rbs_image_script.tar

12. docker load

    docker load <  rbs_image_script.tar
    

13. docker-compose.yml added volumes:

    - "/storage0/app:/storage0/app"
    - "/storage0/pipeline1:/storage0/pipeline1"
    - "/storage0/pipeline2:/storage0/pipeline2"
