Mount single file from volume using docker-compose

Question

For local dev I need to mount a different config file in a Docker container. This is easy with the command line -v $(pwd)/bla.yaml:/location/bla.yaml. Is it possible to do this from a volume (created with docker volume create bla) in a docker-compose file?

Answer 1

You should be able to do it with a bind mount:

version: "3.2"    
services:
      app:
        image: app:latest
        volumes:
          - type: bind
            source: ./bla.yaml
            target: /location/bla.yaml
