- ZONE_NAME was "kube.huskypup.net" in both the home-ip-ddns CronJob and
the VPS failover watcher - that's a record, not a Cloudflare zone (the
actual zone is the parent "huskypup.net"). Caused home-ip-ddns to fail
every run (zone lookup returned zero results, curl -f exit 22) -
confirmed live and fixed.
- Added seccompProfile/non-root/dropped-capabilities securityContext to
the three CronJobs added this session that were missing it (flagged by
the cluster's "restricted" PodSecurity admission). Repointed the raft
snapshot job's mc binary install from /usr/local/bin to /tmp so it
still works running as non-root.
Root cause (confirmed via ztunnel logs): the argo-cd chart's default
NetworkPolicies only allow each component's application port (e.g. 6379
for redis), but Istio ambient mode routes ALL pod-to-pod traffic through
ztunnel's HBONE tunnel on port 15008 first - so the tunnel itself was
being blocked even though the "real" port was allowed. Every inter-pod
connection in the argocd namespace hung for exactly 10s then reset;
ztunnel's own log named it directly ("connection timed out, maybe a
NetworkPolicy is blocking HBONE port 15008"). This broke argocd-server's
Redis-backed session/cluster-info caching cluster-wide and was silently
preventing the root Application from picking up new child Applications.
Fix: additive NetworkPolicy allowing ingress on 15008 for all argocd
pods (NetworkPolicies union across multiple policies selecting a pod,
so this doesn't touch/replace the chart's rendered ones - safe across
Helm upgrades).
Also: dropped argocd from the namespace-enrollment job's waypoint list.
argocd's only AuthorizationPolicy (allow-argocd-access) is a plain
source-namespace/IP match with no L7 rules - its own status shows
"attached to ztunnel", not waypoint - so forcing L7 waypoint processing
onto the namespace was unnecessary overhead, not a security requirement.
ztunnel's mTLS still fully covers it. (This was a red herring for the
HBONE bug itself, not the fix, but a valid simplification found along
the way.)
Foundation for a DR/backup path using an always-on VPS as a second
ArgoCD-managed cluster, plus DB/backup standardization work that fell
out of it:
- vps-standby ArgoCD cluster destination + AppProject, MinIO backup
receiver, VPS bootstrap script (k3s, Netbird, cert-manager)
- Dual-site DNS failover watcher + home-IP DDNS CronJob, Cloudflare
token moved out of git into Vault+ExternalSecret
- Nextcloud migrated from ad-hoc MariaDB to CNPG + redis-operator
(matches n8n/Authentik/GitLab's backup-native pattern)
- Authentik's CNPG manifests moved into the actual ArgoCD-synced
manifests/ path (were present but never wired into the sync path)
- Vault raft-snapshot CronJob, CNPG barmanObjectStore backups
(Authentik/n8n/Nextcloud), Nextcloud file-PVC restic sync - all
targeting the new VPS MinIO receiver
See VPS Warm-Standby plan doc for full design rationale.
Gitaly CPU limit was 250m causing throttling on git operations (485ms
p99 to webservice). Increased to 1 core with 100m request. Also added
workerProcesses: 3 to webservice for better request concurrency
(was default 2).

Traffic goes through Istio (not Envoy Gateway), so cookie-based
consistent hashing must be on the Istio DestinationRule. Removes
the unused Envoy Gateway BackendTrafficPolicy.

Fixes OIDC nonce validation failures with 2 replicas by using a
BackendTrafficPolicy with cookie-based consistent hashing instead of
Service-level ClientIP affinity (which doesn't work behind Envoy proxy).

With 2 replicas, OIDC callbacks can hit a different pod than the
one that generated the state/nonce, causing auth failures. Session
affinity ensures the same client always reaches the same pod.

Change EXTENSION_PRIORITY from "*,openid" to "openid,*" so
unauthenticated users are redirected to Authentik OIDC instead
of seeing the database login form.

Fixes NameError: uninitialized constant Gitlab::Redis::ALL_CLASSES
caused by 7_prometheus_metrics.rb loading before 7_redis.rb
(alphabetically 'p' < 'r'). The ConfigMap provides a 0_redis_early.rb
initializer that requires gitlab/redis before other initializers run.

- Scale CNPG pg-teslamate to 1 instance: on-disk storage corruption
(corrupted sequences, system catalog indexes) means replicas cloned
via pg_basebackup inherit corruption and can't open any database.
Primary works from cached catalogs. Sequences already rebuilt live.
- Remove talos-cp-02 from Rook-Ceph nodes list: ceph-volume inventory
hangs on BIOS partition via nsenter lvs in host namespace. Talos
read-only /etc prevents LVM filter fix. OSD 1 keeps running from
its existing deployment.

Home Assistant was returning 400 errors because it received
X-Forwarded-For headers from the Istio ingress gateway but wasn't
configured to trust reverse proxies. Add use_x_forwarded_for and
trusted_proxies to the init container's configuration.yaml template.

- n8n: Set replicaCount=1 (RWO PVC incompatible with multiple replicas),
add resource limits to satisfy Kyverno policy
- gitlab: Add ignoreDifferences for redis-gitlab-additional service
(port names and selectors managed by Redis operator)
- netbird-operator: Add ExternalSecret for netbird-mgmt-api-key in
netbird namespace and add manifests source to Application

Webservice was at 94% memory (1875Mi/2Gi) with only 50m CPU request,
causing CPU throttling and slow first requests after idle periods.

s6-overlay's log-prepare needs chmod on /dev/shm/logs/* which
requires CAP_FOWNER when all capabilities are dropped.

- Revert talos-client-cert secret to prometheus namespace (prometheus
pods mount this secret, not kube-system pods)
- Add CHOWN/DAC_OVERRIDE/SETUID/SETGID capabilities to frigate
(s6-overlay needs chown for log directories)
