Docker: adding a file from a parent directory

1. cd to your parent directory instead
2. build the image from the parent directory, specifying the path to your Dockerfile

docker build -t <some tag> -f <dir/dir/Dockerfile> .

In this case, the context of the docker will be switched to the parent directory and accessible for ADD and COPY

With docker-compose, you could set context folder:

# docker-compose.yml

version: '3.3'    
services:
  yourservice:
    build:
      context: ./
      dockerfile: ./docker/yourservice/Dockerfile
