Documentation

Overview

Command zonegitd is the authoritative DNS responder backed by a zonegit repository.

Scope:

• UDP + TCP listener
• One zone per process (--zone, auto-loaded from the repo if persisted)
• Serves the HEAD of --branch by default
• --at <refish> pins serving to a historical commit (time-travel)
• --canary <branch>:<pct> splits traffic between --branch and a canary
• Responds to AXFR with the full zone
• Optional /metrics endpoint

Hot reload: the daemon does NOT reopen Badger per query. A background poller (pkg/resolve.PollingSnapshotter) reopens the read-only handle only when a watched branch's tip hash changes. Per-query cost is one atomic pointer load.
