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

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.

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/compose-file-v3/#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:

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

I know it's late to answer but I'm mostly writing this for the community.

Answer:

You only need to do it like this:

    volumes:
       - ./root/instantclient_12_2/ojdbc8.jar:/etc/kafka-connect/jars/ojdbc8.jar
       - type: bind
         source: $HOST/etc
         target: /kernel-etc

Then, for running it in 'easy to debug mode' do it first with docker-compose up and when you made sure it was working fine put a ring on it by adding a -d at the end.

Important Notes

1-Make sure your docker-compose version is at least 3.2 and in my case, it is3.7. for updating and getting rid of the old version do as below:

sudo apt-get remove docker-compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

2- Don't forget to rm your old container so you don't face weird port-related issues. heres how:

docker container stop YOUR_CONTAINER_ID
docker container rm YOUR_CONTAINER_ID

Good luck.

As of Docker 3 on OSX, I had to disable Experimental Feature gRPC and restart as per: https://github.com/microsoft/vscode-remote-release/issues/4171
