KCNA Networking & Service Discovery

Question 1

What is the purpose of Kubernetes service discovery?

Accepted Answer

To facilitate communication between pods and services

Answer

Kubernetes service discovery allows applications running in pods to find and communicate with other services within the cluster without needing to know their specific IP addresses. It achieves this by assigning stable network identities (DNS names and virtual IPs) to services, abstracting away the dynamic nature of pod IPs.

Question 2

Which component manages network communication between Kubernetes Pods?

Accepted Answer

Kube-proxy

Answer

Kube-proxy is a network proxy that runs on each node in the Kubernetes cluster. It is responsible for implementing the Kubernetes Service concept, maintaining network rules on the host to enable network communication to your Pods from inside or outside of the cluster.
