Dec 1, 2024

Month 2024-12 — nginxinc/kubernetes-ingress: Delivered two high-impact features and improved operational reliability for Kubernetes Ingress with NGINX Plus. Implemented NGINX Plus license secret management and a dedicated management configuration map for the Ingress Controller (R33), along with updates to CI/CD pipelines, Dockerfiles, and Helm charts to enable seamless license handling and feature integration. Upgraded the nginx-plus-go-client to v2 and nginx-prometheus-exporter, and simplified logger configuration by removing go-kit dependencies in favor of a context-aware logger. These changes enhance licensing compliance, feature parity, observability, and maintainability while reducing configuration and dependency complexity.
