quench-observability-stack

Scored 14 Sept 2026

Hardened, operator-free observability stack: Prometheus + Grafana + Alertmanager + kube-state-metrics + node-exporter + cAdvisor, wired together for metrics, alerting, and populated Kubernetes dashboards. No Prometheus Operator, no CRDs. All components are QuenchWorks-hardened, nonroot, 0-CVE images pinned by digest and cosign-signed. node-exporter and cAdvisor take host access by design (the stack's purpose is node + container observability); both are toggleable.
