How to add volumes to docker mongo container

Question

web:
  build: .
  command: python3 /app/app/__init__.py
  ports:
    - "5000:5000"
  volumes:
    - .:/app
  links:
    - db

db:
  image: mongo:3.6.5
  ports:
    - "27017:27017"
  command: mongod --smallfiles --logpath=/dev/null # --quiet

This is my docker-compose.yml . I have a database dump in this same folder which is a collection of json and bson files. I want to avoid doing mongorestore again and again and want my flask app to take data from the dump directly as soon as I do docker-compose up.

Answer 1

Use this:

volumes:
        - '/home/sa/data/db:/data/db'

/home/sa/data/db is dump files folder on host

/data/db is a folder in docker container.
