Quarantine and write were separate round-trips, so a failure between them
left the PVC with no zone data and the next reconcile reseeded at serial 1.
The write also truncated the destination in place, leaving a torn file that
PlanSeed refuses to touch.
Dynamically-updated primary zones were only reaching the secondary pods on
the hardcoded 1h SOA refresh: the operator emitted no NOTIFY, and a zone's
only apex NS is the primary itself, so default 'notify yes' reached no one.
Queries load-balanced across the serve VIP hit stale secondaries and
returned NXDOMAIN (negatively cached downstream for the 300s SOA minimum),
so records flapped for up to an hour after every update.
Add 'notify explicit' + 'also-notify' with the secondary pod IPs to primary
zone stanzas so an update NOTIFYs the secondaries for an immediate IXFR.
Applied via modzone, so existing zones pick it up on the next reconcile.
Also shorten the seed SOA refresh/retry/minimum as a fallback for missed
NOTIFYs and to shrink stale-NXDOMAIN negative caching.
Two bugs made every provisioned zone fail to load:
1. The seed zone's apex NS (ns1.<zone>) is in-zone but had no address
record, so BIND check-integrity refused to load it and rndc addzone
reverted. Add a glue A record pointing at the primary pod IP.
2. Secondaries rendered primaries/default-primaries with the primary's
DNS name, but BIND only accepts IP addresses there (it read the name
as a remote-servers list and failed config load, crash-looping the
secondary). Render the primary pod IP instead, and watch Pods so the
config re-renders when that IP appears or changes.
- bind.WriteSeedZone writes 'ns1 IN A <primaryIP>' glue
- controllers resolve primaryPodIP and pass it to the seed (requeue if
the primary has no IP yet)
- BindCluster renders PrimaryAddress from pod-0's IP and watches Pods
- render omits catalog primaries when the IP is unknown (no empty list)
Implements a Kubernetes operator that manages fleets of BIND9 servers
declaratively, using controller-runtime (matching forgebot conventions).
- add BindCluster reconciler: StatefulSet (pod-0 primary, secondaries),
headless + client Services, rendered named.conf ConfigMap, TSIG keys
Secret and rndc control Secret; watches dependent CRs to re-render
- add BindTSIGKey reconciler that generates key material into a Secret
- add BindZone/DNSRecord reconcilers using fully-dynamic delivery
(rndc addzone + TSIG nsupdate against the primary pod)
- add BindCatalogZone reconciler so secondaries auto-provision zones
- add BindPolicy (RPZ), BindDNSSECPolicy, BindView, BindACL reconcilers
- render primary/secondary named.conf variants selected by pod ordinal
- generate CRDs, deepcopy and RBAC; add samples mapping the three Puppet
roles (authoritative/resolver/external-dns) to three BindClusters
- add Makefile, Dockerfile.operator, Woodpecker CI and kind manifests
