claude-botandClaude Fable 5.1 6008d59c9f fix(reloader): restart audiobookshelf and immich-server on ConfigMap change
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/ci-manifests-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Both consume their ConfigMap with envFrom, which Kubernetes does not
watch: a changed value applies in git and in the cluster while the
running container keeps the environment it started with. Paperless hit
exactly this in #739 and got the annotation in #741; these two were the
remaining envFrom consumers without one.

ftp-scanner, the third Deployment named in the issue, needs nothing: its
ConfigMap comes from a configMapGenerator that deliberately keeps the
content-hash suffix, so any change renames the ConfigMap, mutates the
pod template and rolls the pod on its own.

Reloader already watches all namespaces (kubernetes/infrastructure/reloader).

Fixes #742

#817 pinned the digest from the branch build (pipeline 8452). Merging
#816 rebuilt the same date tag on master (pipeline 8457), Gitea kept
only the new manifest, and the pod has been in ImagePullBackOff since:
"failed to resolve reference ...@sha256:0d266b02...". With the Recreate
strategy no controller is running, so the services are unchanged.

The kaniko step of the master build pushed sha256:caffa308...; that is
the digest to pin. Comment states the rule.

Pins the controller image by digest. The registry tag is the build
date and pipeline 8452 rebuilt today's tag in place, so the tag alone
cannot carry a new build to the cluster; the digest can.

Merge only after the Traefik change from 1/2 has reconciled: from this
build on every service target sends a PROXY protocol v2 header, and
Traefik drops such connections unless websecure trusts the pod CIDRs.

TLS-passthrough services hand Traefik a raw TCP stream, so every WAN
request now logs the routing peer's pod IP (10.244.4.64/.112 in the
access log) instead of the client. CrowdSec's detection parses exactly
that log; with the HTTP-mode services gone it would attribute every
external request to two pod IPs, and a re-armed bouncer would repeat the
2026-06-27 mass ban.

The controller now sets options.proxy_protocol on every target (PROXY
protocol v2, TCP/TLS modes only per NetBird) and treats a service
without it as out of date, so the eleven existing services are updated
on the next pass. Traefik's websecure entrypoint accepts the header from
the pod CIDRs, mirroring forwardedHeaders.trustedIPs. Traefik takes
connections with or without a header from a trusted IP, so mesh and LAN
traffic that carries none is unaffected and the Traefik change can land
before the controller image.

is the branch build that pushed this exact code.

The OpenBao role is applied once by hand (policies/netbird-proxy-services
.hcl); until then the pod logs an auth error per minute and changes nothing.

netbird-proxy-services reconciles the NetBird reverse-proxy services that
nobody managed so far: one TLS-passthrough service on :443 per host of every
Ingress carrying dns.renner.uno/public, targeting Traefik ClusterIP through
a subnet resource over the service CIDR. SNI and Host reach Traefik
untouched, the proxy terminates nothing, no domain resource is involved --
so the dns-interceptor pinning bug that wedges the proxies on every
routing-peer loss has nothing to pin on.

Ownership is derived from NetBird, not from local state: managed iff mode is
tls and the target is the controller subnet resource. The ten hand-made
HTTP/domain services are reported as held and never touched; migration is
deleting one of them, the controller creates the passthrough on its next
pass. The PAT is read from OpenBao per pass through a read-only role
(policies/netbird-proxy-services.hcl, applied once by hand like the rotator
roles). Standard library only; unprivileged image built alongside heating-can.

Validated against the live management (ONCE=1 through the rotator role):
network, resource, router and policy created, 10 hosts held, one host that
had no service at all (llm.renner.uno) created and answering behind its
Authentik gate; second pass 0 created / 0 updated / 0 deleted.

ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Every loss of the routing peer a proxy has pinned wedges its route
manager; the flood watchdog restarts the container within 2 s and the
public edge is back after one failed probe round. Inside the 600 s
cooldown the restart is suppressed and the URL watchdog three one-minute
rounds are the only recovery: 3.5 min of 000 on every public domain,
measured 2026-09-07 10:28 on proxy-2 ("restart suppressed, last restart
567s ago"). The morning node roll hit the same suppression on both
proxies at 06:58 and survived only because the routes recovered by luck.

Rolling reboots lose one peer every few minutes by design, so with 600 s
the second roll is always the unlucky one. A minute keeps the loop
protection (one restart per probe interval at most).

infrastructure-crds has applied it. The copy in crowdsec/lapi-ingress.yaml
goes; the Ingress stays (core kind). With it, the infrastructure apply set
holds no traefik.io consumer any more, which is what a cold rebuild needs.

Prune: infrastructure reconciles first and skips the object if the last
applier label names infrastructure-crds; otherwise it deletes and
infrastructure-crds recreates it seconds later. Only the public LAPI
ingress used by the external bouncers is behind that transport.

ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/ci-manifests-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Since the host-device rollout (#801) Rook cannot finish a CephCluster
reconcile: it runs a canary pod with OSD placement to read the cluster
CIDR off the attachment, the OSD on that node already holds the NIC, and
the canary fails "error adding container to network ceph-san" until the
15-minute discovery timeout, then the next reconcile repeats it. Under
macvlan the canary could sit beside the OSD; a whole-device attachment has
exactly one consumer per node.

Discovery is skipped when addressRanges.cluster is set (Rook: "if user
specifies CIDRs in the network config, that is the definitive source of
truth"). The value is what discovery produced and what ceph config already
holds, so no daemon changes. The old comment claiming addressRanges is
honoured only under provider: host was wrong — the CRD documents it for
host and multus.

ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/ci-manifests-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Every node has a second, address-less NIC (enp87s0) up on the untagged
fallback network, which shares the mgmt VLAN's broadcast domain. With
the Linux default arp_ignore=0 the host answers ARP for the node IP from
that NIC too, so the UDM can learn 10.2.40.x against enp87s0's MAC.
Inbound IPv4 then arrives on a device Cilium is not attached to, never
reaches cil_from_netdev, and is routed straight back to the UDM by the
default route — a loop that made every IPv4 LoadBalancer VIP on the
affected node unreachable for 13.5 hours. IPv6 was untouched because
NDP only answers on the interface that owns the address.

The flux was measurable on all three nodes: an ARP request for a node
IP from a neighbour returned replies from two MACs. Which node's entry
had actually flipped at the UDM was a race, and it moved during the
diagnosis.

arp_ignore=1 answers only when the target address is configured on the
receiving interface; arp_announce=2 stops the host from sourcing ARP
from an interface that does not own the address. Applied live with
talosctl on all three nodes before this commit and verified with
enp87s0 up: each node now answers from its mgmt0 MAC only.

A node property, so it lives next to the existing enp87s0 sysctls in
each machine patch rather than in the site patch.

ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/ci-manifests-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
A cold rebuild stops permanently at the infrastructure Kustomization:

  ServersTransport/crowdsec/crowdsec-lapi dry-run failed: no matches for
  kind "ServersTransport" in version "traefik.io/v1alpha1"

Flux dry-runs the whole apply set, so this one unknown kind rejects all of
it — including the Traefik HelmRelease that installs the CRD. Measured on
the Hetzner rehearsal from master: zero HelmReleases, zero CRDs. The
public LAPI endpoint (2026-09-02) landed after the post-crds sweep and put
a traefik.io consumer back into the layer that creates traefik.io.

Phase 1 only adds the object under post-crds; crowdsec/lapi-ingress.yaml
keeps its copy until infrastructure-crds has applied once, because both
Kustomizations prune and a one-commit move deletes before the new owner
applies. Phase 2 removes the original.

ci/woodpecker/pr/ci-manifests-test Pipeline was successful
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
The NetworkAttachmentDefinition switches from a macvlan on a kernel
interface name to host-device on the role name `ceph-san`. The NIC is
dedicated to Ceph and has exactly one consumer per node, so it is moved
into the OSD pod whole — real MAC, real MTU — and returns to the host when
the pod goes away. No hardware name appears in this file any more; every
machine renames its own link at boot (previous commit).

ROLLOUT — not atomic with the machine config. Between this flip and a
node's reboot, an OSD restart on that node fails: the NAD asks for
ceph-san and the running node only has the old name. Merge only inside a
maintenance window, then drain + noout + reboot k8s-1/2/3 back to back.
Running OSD pods keep their existing attachment until restarted.

Source of truth: every Ingress carrying the public label (dns.renner.uno/public).
For each host on such an Ingress the NetBird management gets one reverse-proxy
service in TLS-passthrough mode on :443, targeting Traefik's ClusterIP through a
subnet resource that covers the cluster's service CIDR. SNI and Host reach
Traefik untouched, the proxy terminates nothing, and no domain resource is
involved -- the routing peers stay ordinary IP routers. The target sends a
PROXY protocol v2 header so Traefik (and CrowdSec behind its access log) sees
the WAN client address instead of the routing peer's pod IP.
Ownership is derived from NetBird itself, not from local state: a service is
managed iff its mode is "tls" and its target is this controller's subnet
resource. Services that do not match (the hand-made HTTP/domain ones) are never
touched; a desired host held by such a service is reported and skipped until
that service is removed by hand.
Credentials: the NetBird PAT is read from OpenBao on every pass through the
Kubernetes auth role, exactly like the setup-key rotator; it never lands in a
Kubernetes Secret or in a log line.
