Standing up energy and cost observability on Kubernetes

Terraform and Helm modules for the measurement stack.

Ten Terraform modules distributing the GreenOps measurement stack: Prometheus and Grafana, Kepler and Scaphandre for hardware power, CodeCarbon, OpenCost, grid-intensity data, and KEDA and KubeGreen for acting on what you learn. The umbrella module defaults to observability-only, so the first apply cannot disturb production. The problem it solves is assembly: nine upstream projects whose interactions are mostly discovered by failing.

What is in it

  • The problem — what goes unanswered without it, and who notices first.
  • Why the obvious alternative falls short — stated plainly, including where it is the better choice.
  • How it works — the method, not a feature list.
  • Concrete use cases — with console output quoted from the repository, never reconstructed.
  • The methodology behind any number it emits — every term shown, so the figure survives a question.
  • What it deliberately does not do — the section most papers leave out.
