Kubernetes Services Explained

What are Kubernetes Services?

Kubernetes services are an abstraction that defines a logical set of pods and a policy by which to access them. This abstraction allows for stable networking and communication between different components of an application.

Types of Services

• ClusterIP: The default type, which exposes the service on a cluster-internal IP. This means that the service is only reachable from within the cluster.
• NodePort: This type exposes the service on each node’s IP at a static port. A NodePort service can be accessed from outside the cluster by requesting :.
• LoadBalancer: This type creates an external load balancer in the cloud (if supported) and assigns a fixed, external IP to the service.

By using services, Kubernetes ensures that communication between pods is seamless and reliable, regardless of the underlying infrastructure.
