In this video I am implementing the nginx ingress controller into my cluster. The ingress controller allows us to route traffic to different destinations in our cluster so that we can reach the services we setup in the future. I will walk through what an ingress controller is, find the helm chart, download and customize the values file, deploy the ingress controller and test its functionality.
