Adds BindCluster.spec.service.externalTrafficPolicy so DNS LoadBalancers
can preserve client source IPs (Local), which the source-IP ACLs on the
authoritative/resolver need to actually restrict external clients (Cluster
SNATs everything to node IPs).
- api: ClusterServiceSpec.externalTrafficPolicy (enum Cluster;Local)
- set it on the client Service for LoadBalancer/NodePort types
- regenerate CRDs + install.yaml
TSIG keys were included in every cluster's keys.conf namespace-wide. When
multiple clusters share a namespace, that leaks keys across clusters. Add
spec.clusterRef so a key can target a specific BindCluster; empty keeps
the shared (all-clusters-in-namespace) behaviour.
- api: BindTSIGKey.spec.clusterRef (optional)
- BindCluster keys.conf now includes only keys with matching or empty
clusterRef
- regenerate CRDs + install.yaml bundle
Adds config/crd/install.yaml (all 9 CRDs concatenated) so downstream
GitOps can reference the CRDs by a single stable raw URL instead of
vendoring copies.
- make generate now writes config/crd/install.yaml from config/crd/bases
The dynamic mode produced a byte-identical cluster to authoritative:
RFC2136 update capability is a per-zone property (BindZone.dynamicUpdate
+ updateKeyRef render allow-update { key ... }), not a cluster role. The
external-dns tier is just an authoritative cluster whose zones allow
dynamic updates.
- remove BindMode dynamic from the enum and constants
- switch the external-dns sample to mode authoritative
- update README migration mapping
Uses internetsystemsconsortium/bind9 as the default base image instead of
a self-hosted one, verified against internetsystemsconsortium/bind9:9.20
(runs as root; named/rndc/nsupdate at /usr/sbin,/usr/sbin,/usr/bin).
- project operator config at /etc/bind-operator instead of overmounting
the image's /etc/bind (keeps bind.keys / base config intact)
- reference named/rndc/nsupdate by absolute path (exec PATH may exclude
/usr/sbin)
- centralise filesystem + binary paths in internal/bind/consts.go
- default spec.image to internetsystemsconsortium/bind9:9.20
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
