• Jun 30, 2026 Connectivity coredns-app v1.31.0

  Changed

  • Standardize values.yaml comments to the # @schema / # -- (helm-docs) convention and remove section-header dividers, so values.schema.json and the chart README.md are generated from the values file. Rendered manifests are unchanged.

  Added

  • Wire up the full set of CoreDNS forward, cache, and kubernetes block parameters in the structured zone config:
    • forward: maxIdleConns, maxConnectAttempts, dohMethod, tls, tlsServername, next, nextOnNodata, failfastAllUnhealthyUpstreams, failover, resolver.
    • cache: zones, serveStale.verifyTimeout, disable.successZones, disable.denialZones.
    • kubernetes: endpoint, tls, kubeconfig, apiserverQPS, apiserverBurst, apiserverMaxInflight, namespaceLabels, fallthroughZones, multicluster, startupTimeout.

  Fixed

  • Render the health directive in only the . server block. The health plugin is process-wide and can be enabled in just one Server Block, so emitting it in every zone block was invalid. ready is kept in every block (its readiness is aggregated across blocks).
  • Correct the coredns.*.cache.serveStale.refreshMode schema enum to immediate/verify (was immediate/background), matching the CoreDNS cache plugin.

  Refactored

  • Restructure Helm chart values interface with a zone-aware coredns.* layout; all old paths remain backward compatible.
  • Add coredns.public.* for the forward zone: autopath and a structured forward map mirroring the CoreDNS forward block, including maxConcurrent (max_concurrent).
  • Migrate the CI test value files to the new coredns.* interface.
  • Add coredns.cluster.* for the in-cluster zone: domains, serviceCIDR, podCIDR, and a structured kubernetes map mirroring the CoreDNS kubernetes block.
  • Add coredns.custom.
  • Add controlPlane.*, securityContext.*, service.clusterIP, and ports.metrics.port.
  • Configure cache, log, and loadbalance per zone (coredns.public.*, coredns.cluster.*, and each coredns.additionalZones[].*), replacing the former global coredns.cache, coredns.log, and coredns.loadbalance (removed). A zone that omits them falls back to the deprecated paths, then to built-in defaults.
  • Replace coredns.additionalLocalZones (a list of zone-name strings) with coredns.additionalZones, a list of fully-templated zone objects. The deprecated top-level additionalLocalZones string list still renders as kubernetes zones, now inheriting the coredns.cluster.* cache, log, and loadbalance config.
