What is a Kubernetes Service?
- AAn abstraction that exposes a set of Pods over the network with a stable endpoint
- BA container running inside a Pod that handles incoming network requests
- CA DNS server built into every node that resolves external domain names
- DA firewall rule applied to the cluster that controls traffic between Pods
Why this is the answer
A Service provides a stable IP address and DNS name that routes traffic to a dynamic set of Pods. Even as Pods are created and destroyed, the Service endpoint stays the same.
