Service discovery in Kubernetes is a critical feature that enables pods to communicate with each other within the cluster. In Kubernetes, services abstract a group of pods, making them accessible via a single DNS name or IP address. This abstraction allows applications to communicate without needing to know the specifics of each pod's location or IP address.
When a service is created, Kubernetes automatically assigns a stable IP address (called the ClusterIP) and a DNS name. These services are registered with the cluster's DNS, typically managed by CoreDNS. When a pod needs to communicate with another service, it requests the service's DNS name. CoreDNS resolves this DNS name to the service's ClusterIP, which then forwards the request to one of the pods behind the service.
