Kubernetes Services and Networking
Kubernetes provides a robust networking model that allows you to expose your applications to the outside world, balance traffic, and manage internal communication between your microservices. In this tutorial, we’ll explore different types of Kubernetes Services and how to create a LoadBalancer service using a practical example.
Service Types
Kubernetes Services are an abstraction that defines a logical set of Pods and a policy by which to access them. There are several types of Services in Kubernetes:
1. ClusterIP
ClusterIP is the default type of service. It exposes the service on an internal IP in the cluster. This type of service is only accessible within the cluster.
Use Case: Internal communication between microservices within the same cluster.
2. NodePort
NodePort exposes the service on each Node’s IP at a static port (the NodePort). A ClusterIP service, to which the NodePort service routes, is automatically…
