Inspecting the Stack File: Services

Services are where most of the action happens. Our application defines two, and we’ll look at each.

The web-fe service

As you can see, the web-fe service defines an image, an app, the desired number of replicas, rules for updating the app, a restart policy, which network to connect to, which ports to publish, and how to mount a volume.
