docker-compose: define mount for bind mount and managed mount

问题

I'm using docker-compose for defining my service. In docker, there are two concepts for docker volume. Firstly is about bind mount: mount on host storage.

docker run -d --name web-app -v $HOST/location:/container/location -p 80:80 httpd:latest

Secondly is about managed mount: abstract storage, not depend on host.

docker run -d --name web-app -v /container/location -p 80:80 httpd:latest

I want to map those concepts to docker-compose. It means how can I define bind mount and managed mount when using docker-compose.

回答1:

You can find these Docker concepts in the volumes section of Docker Compose: https://docs.docker.com/compose/compose-file/#/volumes-volumedriver

Examples:

volumes:
  # Just specify a path and let the Engine create a volume
  - /container/location

  # Specify an absolute path mapping
  - ./myfolder/location:/container/location

Although I am answering very late. But maybe it helps other people in future. Below is the configuration for both types. https://docs.docker.com/compose/compose-file/#volumes

    version: "3.2"
    services:
     web:
      image: httpd:latest
      volumes:
       - type: bind
         source: $HOST/location
         target: /container/location
       - type: volume
         source: mydata
         target: /container/location
     volumes:
      mydata:
