Kube-Prometheus-Stack Resources: Official Docs, GitHub & Artifact Hub

Every guide on this site ultimately traces back to a small number of upstream sources: one GitHub repository, one Artifact Hub listing, and a handful of independently maintained project docs. Here's exactly where each one lives and what it's actually useful for.

The Official GitHub Repository

kube-prometheus-stack's source lives in prometheus-community/helm-charts, specifically under charts/kube-prometheus-stack. This monorepo holds dozens of prometheus-community charts, not just this one, so the chart's specific CHANGELOG.md and README live inside its own subdirectory rather than at the repo root.

This is also where to file a real bug report or feature request — issues filed against the wrong repository (the separate kube-prometheus manifests project, for instance) routinely sit unanswered simply because the wrong maintainers see them.

Artifact Hub Listing

Artifact Hub's listing for the chart is the fastest way to check something without cloning the repository: every published version, the full default values.yaml for each one, install snippets, and security/signing metadata, all rendered in one page. It's the right first stop when checking "does version X support Y" before digging into GitHub directly.

Upstream Docs for Each Component

kube-prometheus-stack packages several independent open-source projects, and each one maintains its own documentation outside the chart entirely:

• Prometheus & Alertmanager — prometheus.io/docs, covering PromQL, alerting rules, and the underlying storage model.
• Grafana — grafana.com/docs, covering dashboard JSON, data sources, and authentication in far more depth than the chart's README does.
• Prometheus Operator — the prometheus-operator project itself documents every CRD field the chart exposes through values.yaml.

The chart's own documentation covers how these pieces are wired together — it's rarely the right place to learn PromQL syntax or Grafana panel options from scratch.

Community & Support Channels

Beyond GitHub issues, the Kubernetes Slack's #prometheus-operator channel is where most day-to-day questions about the chart get answered in real time, and CNCF's Prometheus community meetings are open to anyone tracking longer-term project direction.

License and Governance

kube-prometheus-stack is licensed under Apache 2.0, as are Prometheus, Grafana's core edition, and the Prometheus Operator individually — permissive enough for commercial use without attribution requirements beyond preserving the license itself. Prometheus and the Prometheus Operator are both graduated projects under the Cloud Native Computing Foundation, which governs their long-term roadmap independently of any single company; the Helm chart itself is maintained by the volunteer prometheus-community organization rather than a commercial vendor, which is worth knowing when evaluating how much long-term support to expect versus a vendor-backed alternative.

Frequently Asked Questions

Where is the source code?

In prometheus-community/helm-charts on GitHub, under charts/kube-prometheus-stack.

Where can I see every available version?

Artifact Hub's listing shows every published version with its full default values.yaml.

Where do I learn PromQL or Grafana dashboards in depth?

The upstream Prometheus and Grafana documentation, not the chart's own README.

Conclusion

Almost every "where do I find" question about kube-prometheus-stack resolves to one of these four places — the GitHub repo for source and issues, Artifact Hub for version history, upstream docs for the individual tools, and the Kubernetes Slack for real-time help.
