**Stacked on #228** (needs operator v0.1.5). Merge #228 first; the diff collapses to just this after. ## Why Writes (RFC2136/nsupdate) must go to pod-0 — the round-robin read Service would land them on a secondary (rejected). Adds a dedicated write endpoint per cluster (operator v0.1.5 `primaryService`). ## Changes - `bind-authoritative`: LoadBalancer write endpoint on **198.18.200.9** (`bind-authoritative-primary`) - `bind-externaldns`: ClusterIP write endpoint (`bind-externaldns-primary`, for in-cluster writers) - regenerate the bindcluster kubeconform schema (primaryService + externalTrafficPolicy) ## Deferred external-dns is **not** repointed at `bind-externaldns-primary` yet: it authenticates with the existing TSIG key, which the operator-generated key won't match until the planned Vault-sync + secret-reflection features exist. Until then external-dns keeps writing to the puppet externaldns. ## Validated kustomize build + kubeconform (3 BindClusters valid against the v0.1.5 schema). --------- Co-authored-by: BenVincent <benvin@main.unkin.net> Reviewed-on: #229 Co-authored-by: Ben Vincent <ben@unkin.net> Co-committed-by: Ben Vincent <ben@unkin.net>
