June 2026: Consolidated monitoring strategy and core stability improvements across Rancher repos to enhance observability, deployment flexibility, and security. Key features delivered include a Helm-based Rancher Monitoring Stack that decouples from RPMs (removing the rancher-grafana dependency) and introduces a dedicated project-monitoring Helm chart with Grafana/Prometheus integration, refined Kubernetes component configurations, UI metadata annotations, a monitoring proxy, and hardened nginx/service account settings. A companion Rancher charts update adds a monitoring helm chart with CRDs, RBAC, and lifecycle templates to enable end-to-end lifecycle management of monitoring resources. Supporting work across Prometheus Federator, core components, and image handling includes: build/config updates and test fixes for the Federator deployment; Go module bumps and build-gen steps; shell/SCC operator upgrades for compatibility and performance; dependency and image updates in backup-restore-operator; and nginx image mirroring support (nginx 1.31.2-alpine). These efforts collectively improve deployment reliability, security, and scalability of observability across Kubernetes clusters.
