Run the deployed image with a command to start the application

sudo docker-compose run <service-name> bash

Run as the user id specified and mount a volume of our project to the working directory of the container so that we make edits to the files in the container or on the host. Note that in our docker-compose.yml file, we put a "depends link" for Nota to require the MongoDB container to start (before Nota). This way we don't need to specify the MongoDB container to start when we run the command below.

docker-compose run --user="$(id -u)" --service-ports -v $(pwd):/home/backenduser/app nota bash
