Migrate NGINX from “stable” Helm Charts Repo with ChartCenter

The sunsetting of the ChartCenter central repository and the deprecation of stable Helm repositories have led to significant changes in how the Ingress NGINX Controller for Kubernetes is deployed. Previously, users could rely on a central stable repository to find the official Helm chart for nginx-ingress, but with the advent of Helm 3, chart owners have transitioned to individual repositories, and the stable repos have been delisted from Helm Hub. As a result, the NGINX project now maintains a new ingress-nginx Helm chart available in the GitHub repositories for Kubernetes, requiring users to adapt their installations and updates accordingly. JFrog ChartCenter, a free Helm chart central repository, offers a solution by providing a single source of truth for immutable, secure, and reliable charts, including those for the NGINX Ingress Controller. The transition involves using shell scripts to test and upgrade from the old nginx-ingress Helm chart to the new ingress-nginx chart, with adjustments to configuration values to account for differences between the two. Despite the changes, the process is streamlined, and using ChartCenter as a central repository simplifies the management of Helm charts from various sources, ensuring a more seamless upgrade experience.
