Plan or apply CoreDNS setup for unicast DNS-SD discovery.
apus dns setup
apus dns setup --domain apus.internal
apus dns setup --apply
| Option | Effect |
|---|---|
--domain <domain> |
Wide-area discovery domain (for example apus.internal). |
--apply |
Install/update CoreDNS config and (re)start the service. Requires sudo, macOS only. |
Without --domain, Apus uses discovery.wideArea.domain from config. Setting that domain enables wide-area discovery.
Without --apply, the command only prints:
- Resolved discovery domain and zone file path
- Current tailnet IPs
- Recommended
apus.jsondiscovery config - Tailscale Split DNS nameserver/domain values to set in the Tailscale admin console
With --apply (macOS only, requires Homebrew CoreDNS):
- Bootstraps the zone file if missing
- Adds the CoreDNS import stanza if missing
- Restarts the
corednsbrew service
