{{/*
An abstract way to expose an application running on a set of Pods as a network
service. With Kubernetes you don't need to modify your application to use an
unfamiliar service discovery mechanism. Kubernetes gives Pods their own IP
addresses and a single DNS name for a set of Pods, and can load-balance
across them.

For example, consider a stateless image-processing backend which is running
with 3 replicas. Those replicas are fungible—frontends do not care which
backend they use. While the actual Pods that compose the backend set may
change, the frontend clients should not need to be aware of that, nor
should they need to keep track of the set of backends themselves.
