Service

In Kubernetes, a Service is a way to expose a network application that is running as one or more Pods in your cluster. A Service selects a set of Pods using a selector, and if more Pods are added or removed, the set of Pods that matches the selector will automatically change. The Service abstraction ensures that network traffic can be directed to the current set of Pods for the workload. Kubernetes Services utilize IP networking (IPv4, IPv6, or both) or a DNS external name. The Service abstraction also enables other mechanisms, such as Ingress and Gateway, to be employed.
