A fresh node pull of pihole:latest silently upgraded v5->v6 (Core v6.2.2). v6's default listeningMode=LOCAL drops DNS from non-attached subnets, which killed all cross-node svclb DNS the moment the pod rescheduled off its old node. v6 also ignores the WEBPASSWORD env. - image pinned by digest (Core v6.2.2) - FTLCONF_dns_listeningMode=ALL - admin password via FTLCONF_webserver_api_password <- pihole-admin secret - tcpSocket:53 readiness probe so rollout status waits for FTL Applied to the cluster via kubectl replace; DNS verified answering on all four node IPs, admin API auth verified.

# Pi-hole v6 (image pinned by digest = Core v6.2.2 — :latest bit us on
|
|
# 2026-07-26 when a fresh node pull silently jumped v5→v6).
|
|
# v6 notes:
|
|
# - FTLCONF_dns_listeningMode=ALL is REQUIRED in k8s: the v6 default (LOCAL)
|
|
# only answers queries from directly-attached subnets, which silently drops
|
|
# all cross-node svclb traffic.
|
|
# - v6 ignores the old WEBPASSWORD env; the admin password is
|
|
# FTLCONF_webserver_api_password, fed from the `pihole-admin` secret —
|
|
# create it (see secret.example.yaml) BEFORE applying.
|
|
# - Readiness probe on :53 so rollouts wait for FTL to actually serve DNS.
