Opencost

Opencost is an engine which can give us a real time info to see, how much money is spend on the k8s resources so far it supports namespace, deployment, controller, label, pod, and node.

Why it's in KubeAid​

Cost visibility for workloads running on a KubeAid-managed cluster, without depending on a paid SaaS. It reads usage from Prometheus and turns it into per-namespace/deployment/pod cost, so cluster owners can see where spend is going on their own infra.

https://github.com/opencost/opencost/issues/2022 is raised for getting the same info for volume snapshot

Key values​

Chart wraps the upstream opencost subchart (argocd-helm-charts/opencost/values.yaml):

  • opencost.opencost.prometheus.external.enabled: true, pointed at http://prometheus-k8s.monitoring:9090 — opencost reads cost data from the cluster's existing Prometheus rather than running its own.
  • opencost.opencost.metrics.serviceMonitor.enabled: true — opencost's own metrics get scraped too.
  • opencost.opencost.ui.enabled: true with ui.ingress.enabled: true — the bare-minimum web UI is exposed.
