Cannot start service api on Mac OS Sierra

Hi, after running docker-compose up I get the following error.
It seems like a directory is not existing in the container.

Make sure that there is yarn.lock in the root of your project (it's being created or updated when you run yarn install). Docker-compose is trying to mount this file inside the "api" container:

Looking at the error you get, it seems like Docker Compose cannot find it.
