How to ADD sibling directory to Docker image

Is there a way to copy a sibling directory into my docker image, i.e., something like

ADD ../sibling_directory /usr/local/src/web/

This is not permitted - according to the Docker documentation, all resources accessible by my Dockerfile must be under the Dockerfile working directory.

In my scenario, I am in the process of splitting out worker services from web services from a common code base, and I'd like to do that logically first without having to actually physically separate the code.

Solution

  • Here's what a potential fig.yml might look like:

    web:
    build: ./web/
    volumes:
     - /usr/local/src/web/
worker:
    build: ./worker/
    volumes_from:
     - web
