Root cause of tonight's earlier CrowdSec/CNPG-backup workarounds: no node in the cluster had any route into the Netbird mesh CIDR (100.108.0.0/16) for pod-originated traffic. The per-namespace netbird 'router' pods are inbound-only infrastructure (external peers reaching K8s services); their own architecture has no reverse path. Fix, in two parts: 1. infrastructure/netbird/manifests/egress-daemonset.yaml - one netbird client per node, hostNetwork so its wt0 interface lives in the node's real network namespace, plus a sidecar that adds a host route sending 100.108.0.0/16 out via it. hostNetwork requires a scoped Kyverno PolicyException (infrastructure/kyverno/policies/netbird-egress-exception.yaml) to the disallow-host-namespaces STIG policy - narrowly for this one DaemonSet by name, not a namespace-wide exclusion. 2. Discovered the route alone wasn't enough for k3s NodePort traffic (vps-minio:30900): Netbird manages its own nftables ACLs independent of iptables/Kyverno, and its forward chain (netbird-rt-fwd) only permits *established* connections through a peer acting as a router - never new ones, by design, unless a Netbird 'Network Route' policy is explicitly configured (it isn't, for this VPS). Locally-terminated connections (tinyproxy) go through a separate, already-permissive ACL chain, which is why the CrowdSec proxy fix from earlier tonight worked. Replicated that working pattern for MinIO: minio-forward.service on the VPS host (systemd, socat) forwards 100.108.113.41:9000 -> MinIO's ClusterIP, avoiding the NodePort path entirely. Re-enabled everything that was disabled/suspended earlier tonight because of this gap, pointed at the new endpoint: - CrowdSec CAPI/console-enroll (removed DISABLE_ONLINE_API, restored the VPS proxy env vars) - n8n/nextcloud/authentik CNPG backup.barmanObjectStore - vault-raft-snapshot CronJob (unsuspended) - nextcloud PVC content sync CronJob endpoint vps-minio.netbird.internal is retired everywhere - it was never actually resolvable (Netbird has no DNS configured) even before today's routing fix.

# Backup to VPS MinIO - RE-ENABLED 2026-08-18. Real pod-egress routing to
|
|
# the VPS now exists (netbird-egress DaemonSet, hostNetwork + per-node
|
|
# route into 100.108.0.0/16 - see infrastructure/netbird/manifests/
|
|
# egress-daemonset.yaml). Endpoint changed from the NodePort
|
|
# (vps-minio.netbird.internal:30900 - never resolvable anyway, Netbird has
|
|
# no DNS configured, and separately blocked by Netbird's own ACL model,
|
|
# which only permits *established* forwarded connections through a peer,
|
|
# never new ones) to a locally-terminated socat forward on the VPS host
|
|
# itself (100.108.113.41:9000 - see minio-forward.service on the VPS),
|
|
# mirroring the pattern that already worked for the CrowdSec CAPI proxy.
|
|
# This covers the DB only - file PVC content is separate, see
|
|
# nextcloud-pvc-sync-cronjob.yaml (same fix applies there too).
