How to pass a parameter from docker-compose to service runned in docker image?

问题

My docker-compose.yml, among other images, uses official mongo docker image:

mongodb:
    container_name: mongodb
    image: mongo:3.2
    volumes:
        - mongo_data:/data/db
    ports:
        - "57017:27017"
    restart: always

The problem is that I need mongo deamon to run with --httpinterface option. How can I change my docker-compose.yml to pass this parameter to the final CMD ["mongod"]?

Is it possible without touching the mongo image? Forking this image to only add one parameter would be an overkill.

回答1:

You can use command option of docker-compose.yml

mongodb:
    container_name: mongodb
    image: mongo:3.2
    command: mongod --httpinterface
    volumes:
        - mongo_data:/data/db
    ports:
        - "57017:27017"
    restart: always
