Managing Ingress traffic using the Kubernetes Ingress resource

When building applications that need to be consumed by other applications from outside the network boundary in which the application is deployed, you will need to build an Ingress point using which the consumers can reach the application. In Kubernetes, a Service is an abstraction through which a set of Pods are exposed as a network service. When these services need to be consumed by other applications, they need to be made externally accessible. Kubernetes supports ClusterIP for consuming services internally from within the cluster, NodePort for consuming the service outside the cluster but within the network, LoadBalancer for consuming the services externally via the cloud load balancer, and there are also options for exposing an internal-facing load balancer for internal traffic outside of the Kubernetes cluster. In this section, we will read about how we can configure Istio to expose a service using the Kubernetes Ingress...
