Secondaries reject RFC2136/nsupdate writes, but the read Service round-
robins across all pods. Add an optional per-cluster write endpoint that
targets only the primary pod (ordinal 0) via the StatefulSet pod-name
label. Reads keep using the all-pods Service.
- api: BindCluster.spec.primaryService (*ClusterServiceSpec) — ClusterIP
for in-cluster writers (external-dns) or LoadBalancer for external
- reconcilePrimaryService creates <cluster>-primary selecting pod-0 when
set, deletes it when unset
- regenerate CRDs + install.yaml
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
