Hardened, operator-free observability stack: Prometheus + Grafana + Alertmanager + kube-state-metrics + node-exporter + cAdvisor, wired together for metrics, alerting, and populated Kubernetes dashboards.
Version
The latest line lives at the base page; older lines have their own page so you can pin and verify exactly that version. Only the most recent releases are listed — an older chart pins an older image digest.
