Hardened Kubernetes cost monitoring stack: OpenCost (the CNCF cost model) reading cluster metrics from a bundled Prometheus, plus Grafana with that Prometheus provisioned as a datasource.
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.
