Complete procedures with a way back.

Pin Helm and chart inputs, separate secrets from values and release history, render and server-validate manifests, stage upgrades with bounded waits, verify application behavior, roll back only across compatible data, and operate hooks, CRDs, drift, and secret rotation.

Deploy the actively maintained F5 NGINX Ingress Controller with pinned Helm artifacts, explicit class ownership, hardened replicas, TLS routing, external verification, monitoring, and safe lifecycle controls.
