Services, Load Balancing, and Networking

Concepts and resources behind networking in Kubernetes.

Kubernetes networking addresses four concerns:

Cluster networking provides communication between different Pods.
The Service resource lets you expose an application running in Pods to be reachable from outside your cluster.
You can also use Services to publish services only for consumption inside your cluster.
