Prerequisites: (1) Helm is already installed, see Installing Helm; (2) the cluster has default dynamic storage available, see Providing PV Dynamic Storage with StorageClass 1. Installing Ingress with Helm Ingress consists of two parts: Ingress and the Ingress Controller. In Kubernetes, the Ingress object describes routing rules; the Ingress Controller interacts with the Apiserver and writes the Ingress rules into the Nginx Pod.
