Im trying to share data between a few containers and the host using docker-compose. I have a docker-compose.yml file that looks like this:

version: '3'

services:

  base:

    container_name: base

    build: 

      context: .

      dockerfile: BaseDockerfile

    volumes:

      - dependencies:/volumes/dependencies

  romee:

    container_name: romee

    build: 

      context: .

      dockerfile: RomeeDockerfile

    environment:

      - PYTHONPATH=/volumes/base_dependencies/

    volumes:

      - dependencies:/volumes/base_dependencies   



volumes:

    dependencies:

Now the volume "dependencies" is shared successfully between the containers, but I want to also share it with the host. How can I do that?

The question is equivalent to how to specify a path of a named volume:

Solution:

volumes:

  dependencies:

    driver: local

    driver_opts:

      type: 'none'

      o: 'bind'

      device: '/abs/path/to/dependencies'

EDIT

The complete flow would be like,

Image: Dependency generator, at build time (docker build), generate dependency to /temp, then at run time (docker run / docker-compose up), cp -pr /temp /dependencies, after that it can exit 0.
