Architecture Decision Records

This folder holds progressive architecture decisions for the prometheus-stack deployment.

Use numbered ADR files such as 0001-title.md, 0002-title.md, and so on.

Suggested topics for the first few ADRs once decisions are made:

  • ADR 0001: Pinning the chart to a specific upstream version
  • ADR 0002: Whether to deploy kubeControllerManager / kubeScheduler / kubeEtcd ServiceMonitors on this cluster (managed control-plane vs self-managed)
  • ADR 0003: Authentication strategy for Prometheus / Alertmanager / Grafana ingress (basic-auth, OAuth2, Cloudflare Access, port-forward only)
  • ADR 0004: Long-term metric retention strategy (Thanos / remote-write / none)
