For the last four years, anyone wanting to deploy the Ingress NGINX Controller for Kubernetes would find its official Helm chart nginx-ingress in the stable repository maintained by the Helm project. Those days are over. And not just for NGINX, the most popular Ingress Controller used as a reverse proxy and load balancer, but for all open-source K8s apps. With the advent of Helm 3, the Helm project is deprecating the stable repositories.
