Local DNS zones

DNSZone stores local authoritative records. It can combine manual records with records derived from DHCP leases. The resolver reads these zones through DNSResolver sources.

Example

- apiVersion: net.routerd.net/v1alpha1
  kind: DNSZone
  metadata:
    name: lan
  spec:
    zone: lab.example
    ttl: 300
    dnssec:
      enabled: false
    records:
    - hostname: router
      ipv4: 192.168.160.5
      ipv6: 2001:db8:160::1
    dhcpDerived:
      sources:
      - DHCPv4Server/lan-dhcpv4
      - DHCPv6Server/lan-dhcpv6
      hostnameSuffix: lab.example
      ddns: true
      ttl: 60
      leaseFile: /run/routerd/dnsmasq.leases
    reverseZones:
    - name: 160.168.192.in-addr.arpa

dnsmasq calls routerd-dhcp-event-relay from its DHCP script hook. routerd publishes the lease change on the event bus. routerd-dns-resolver receives the event and updates the in-memory zone table.

The lease file is also read at startup. This keeps local A, AAAA, and PTR records available after a daemon restart.
