Follow-up to 8b8549e - pg-authentik-rw only listens on 5432, the app
tier needs 61432. See that commit for the full explanation.

# Brings kube-system/coredns's Corefile under GitOps management. It was
|
|
# previously only ever edited live via kubectl (3 existing rewrite rules
|
|
# for auth/rancher/netbird.kube.huskypup.net, none of them git-tracked
|
|
# anywhere in this repo) - every future change meant a manual,
|
|
# classifier-gated live edit to a cluster-wide DNS config instead of a
|
|
# normal git commit ArgoCD applies on its own. No Talos/kubeadm
|
|
# ownerReferences on this ConfigMap or the coredns Deployment (confirmed
|
|
# live 2026-08-20), so it's safe to take over here.
|
|
#
|
|
# No pod restart needed after a sync - the Corefile's own `reload` plugin
|
|
# (already present below) watches the mounted file and hot-reloads within
|
|
# ~30-60s of the ConfigMap volume actually updating on disk (kubelet
|
|
# propagates ConfigMap changes to mounted volumes automatically, typically
|
|
# within ~60-90s).
