Kubernetes Cloud Cost Monitoring with OpenCost & Optimization Strategies
summary
CNCF Sandbox OpenCost is an open specification and tool that maps costs to namespaces and labels, scrapes Prometheus (KSM, cAdvisor, node exporter) and calls cloud billing APIs for on‑demand pricing, exposing allocation vs usage and cluster idle costs so teams often find shockingly low efficiency (examples ~10% efficiency). Deploys via manifest or Helm (two‑container pod, written in Go), returns per‑minute metrics and a JSON API/CLI in minutes, does not yet reconcile savings plans from finalized bills, and has an external assets roadmap.
