Kubernetes, Docker, and tailnet services often end up split across ingress objects, container labels, private DNS names, Grafana dashboards, runbooks, and a self-hosted homepage that has to be updated by hand. Compass turns those sources into a searchable service dashboard by discovering Kubernetes HTTPRoute, GRPCRoute, and Ingress resources, Docker containers, Tailscale devices and services, Headscale nodes, static YAML, and JSON APIs.

Headscale is an open source, self-hosted control server compatible with the Tailscale clients. It lets you run your own Tailnet and have full control over users, nodes, keys, and routing policies without relying on Tailscale’s hosted control plane. This post introduces the tailscale-exporter and shows how to collect Headscale metrics via the Headscale gRPC API, and visualize everything in Grafana using dashboards and alerts bundled in the mixin.
