Kubernetes Services and Ingresses
The Service resource helps expose Kubernetes workloads to the internal or external world. As we know, Pods are ephemeral resources – they can come and go. Every Pod is allocated a unique IP address and hostname, but once a Pod is gone, the Pod's IP address and the hostname change. Consider a scenario where one of your Pods wants to interact with another. However, because of the transient nature, you cannot configure a proper endpoint. If you use the IP address or the hostname as the endpoint of a Pod, and the Pod is destroyed, you will no longer be able to connect to it. Therefore, exposing a Pod on its own is not a great idea.
Kubernetes provides the Service resource to provide a static IP address to a group of Pods. Apart from exposing the Pods on a single static IP address, it also provides load balancing of traffic between Pods in a round-robin configuration. It helps distribute traffic equally between the Pods and is therefore the...
