05 | Ingress Controller = NGINX

https://kubernetes.github.io/ingress-nginx/

https://github.com/kubernetes/ingress-nginx

The ingress controller provides external access to services in the cluster by acting as a reverse proxy. In this case, I've selected nginx which is simple to configure, and very fast. It does not have as many fancy features as some other options though.

helm upgrade --install ingress-nginx ingress-nginx   --repo https://kubernetes.github.io/ingress-nginx   --namespace ingress-nginx --create-namespace -f values.yaml
