docker-compose extension field syntax
version: "3"
# See: https://hackernoon.com/a-better-way-to-develop-node-js-with-docker-cd29d3a0093
# This is the v3 syntax to achieve essentially the same thing. Note that if you launched this with a simple
# `docker-compose up` it would attempt to start every definition at the service level, which is not what you
# want! However, you can leverage the fact that `depends_on` launches the listed services prior to the
# dependent service, so in this example `docker-compose up myproject_web` would start the db container
# before the web container. Alternatively, you could just throw the stuff you don't want started with `up`
# into a separate YAML file, as the article demonstrates.
