Kubernetes Service – What It is, Types, Use Cases & Examples

This guide explains the concept of Kubernetes Services, which are resources that map network traffic to Pods in a cluster. Services enable network exposure for one or more cluster Pods and are integral to the Kubernetes networking model. They provide important abstractions of lower-level components, which could behave differently between different clouds. The article covers five types of Service: ClusterIP, NodePort, LoadBalancer, ExternalName, and Headless. It also discusses Ingresses, another type of Kubernetes networking object that's often used in conjunction with Services to control external access based on HTTP and HTTPS routes. Finally, the guide provides examples for creating simple ClusterIP, NodePort, and LoadBalancer Services.
