By using a StatefulSet, each Pod can now be uniquely identified. However, the IP of each Pod is still randomly assigned; we want our Pods to be accessible from a stable IP address. Kubernetes provides the Service Object to achieve this.
The Service Object is very versatile, in that it can be used in many ways. Generally, it is used to provide an IP address to Kuberentes Objects like Pods.
The most common use case for a Service Object is to provide a single, stable, externally-accessible Cluster IP (also known as the Service IP) for a distributed service. When a request is made to this Cluster IP, the request will be proxied to one of the Pods running the service. In this use case, the Service Object is acting as a load ...
