Hardened, operator-free observability stack: Prometheus + Grafana + Alertmanager + kube-state-metrics + node-exporter + cAdvisor, wired together for metrics, alerting, and populated Kubernetes dashboards.

Version

0.0.23 · latest0.0.220.0.21

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.

The chart publishes its attestations on GitHub and the image it deploys carries its own on the same digest, publicly verifiable with the commands above. Both log to the Sigstore transparency log (Rekor), which cosign verify checks for you.
