If we don't specify any service properties when labelling containers, the generated service will be named according to the container. However, we change the container name on every deployment (as it is versioned), which means that the auto-generated service name will be different in each container. That is a problem for two reasons: - Multiple containers share a common router while a deployment is happening. At this point, the router configuration will be different between the containers; Traefik flags this as an error, and stops routing to the containers until it's resolved. - We allow custom labels to be set in an app's config. In order to define custom configuration on the service, we'll need to know what it will be called. Changed to force the service name by setting one of its properties.
