This doesn't always work for me, but it's worth trying. To get a single file mounted inside a docker container as a volume, you have to use the long syntax.

version: "3.7"    
services:
app:
image: app:latest
volumes:
  - type: bind
    source: ./sourceFile.yaml
    target: /location/targetFile.yaml
