title: docker-compose fails to start with npm ERR! enoent ENOENT: no such file or directory, open '/usr/src/app/package.json'
body: <p>I built an image from a docker file to run node and copy in a simple node express app which works perfectly. The image builds I can run a container and bash in and the local files are copied. When I use this image in a docker-compose file along with a mongo image the containers build but the node container fails to run with an error is the package.json is missing.  </p>
  
  <p>The error returned is</p>
