jakman85andClaude Opus 5 c150327a30 fix(oauth2-proxy): gate startup on Keycloak discovery, or a cold boot CrashLoops the proxy
gate / gate (pull_request) Successful in 1m53s
gate / conformance (pull_request) Has been skipped
Exposed by the 2026-10-17 whole-cluster shutdown. oauth2-proxy performs OIDC
discovery ONCE at startup and exits 1 if it fails. On a cold boot Keycloak is
not serving yet, the shared Gateway answers 503, and the proxy dies:

  [provider.go:55] Performing OIDC Discovery...
  [main.go:73] ERROR: Failed to initialise OAuth2 Proxy: ... failed to discover
               OIDC configuration: unexpected status "503": no healthy upstream

It then sits in exponential CrashLoopBackOff long after Keycloak is healthy --
one replica was still down minutes later and only a manual pod delete cleared
it. There is no retry flag, a readinessProbe cannot help (the container is
already dead), and CrashLoopBackOff backoff is not tunable per-pod.

Add an extraInitContainers gate (wait-for-idp) that polls the discovery doc
until it answers. A pod in Init accrues no CrashLoopBackOff backoff and retries
promptly. BOUNDED and FAILS OPEN: after ~5m it starts the proxy anyway, so the
worst case is exactly today's behaviour and never something new.

extraInitContainers is the chart's OWN hook for this -- its commented example is
literally `- name: wait-for-idp` -- and the key was CONFIRMED against the pinned
chart (helm show values, 10.7.1) rather than assumed, because a wrong Helm values
key is silently ignored. No new base image: the chart already runs an alpine init
container for its built-in waitForRedis gate; pinned to 3.22 (verified upstream)
rather than the chart's `latest`.

Rejected: Flux postRenderers (no precedent in this tree, and the chart has a
hook); --skip-oidc-discovery (removes the fetch entirely, but needs four
hardcoded endpoints and I could not verify lazy-JWKS offline -- this component
gates SSO for seven apps, so the additive option wins).

Shell vars are written BARE with no braced form: platform declares
postBuild.substituteFrom, and envsubst would blank a braced shell variable and
silently break the loop. Same convention as the gitea/nextcloud OIDC hooks.

UNAPPLIED; the init container has never run, and the race was not re-created to
prove the fix. Check the init container's log on first apply. See the handoff.

jakman85andClaude Opus 5 0747849837 fix(bulk-nfs): repoint at the TrueNAS (192.168.2.30); the PVs must be recreated, not reconciled
gate / gate (pull_request) Successful in 1m53s
gate / conformance (pull_request) Has been skipped
Both ZFS pools moved off the Proxmox host onto a standalone TrueNAS on
192.168.2.30 -- prod's OWN /24, so the pfSense crossing that made this knob
load-bearing is gone, along with the DNAT at 192.168.2.102 it mounted through.
Measured 2026-10-07: 192.168.2.102:2049 no longer answers; .30:2049 and :111 do.

BULK_NFS_SERVER -> 192.168.2.30 in prod, base and dev. The dev value is marked
inert (dev is decommissioned); it carries the real address only so nothing in
the tree renders a host that no longer exists.

THE OPERATIONAL POINT, and why this is not just a value change: a bound
PersistentVolume's NFS source is immutable. Server dry-run, 2026-10-07:

  spec.persistentvolumesource: Forbidden: spec.persistentvolumesource is
  immutable after creation

so Flux's apply FAILS rather than updating, and the pods keep their old, dead
mount. The five PVs must be deleted and recreated -- safe, because Retain never
touches data and render.py emits a pre-set claimRef so each PV rebinds its own
PVC. The sequence is docs/BULK-NFS-STORAGE.md section 10 and is an OPERATOR
action; this commit does not perform it.

Pairs with the hazard already on the page: spec.nfs.server is unvalidated at
create (any string binds) and immutable at update. A wrong value is accepted
silently and then cannot be corrected in place.

docs/BULK-NFS-STORAGE.md: sections 1 and 5 rewritten for TrueNAS -- the measured
exports, the service settings that decide whether uid 1000 survives the wire,
the three stale ZFS sharenfs properties that had to be cleared, and the ACL
hazard (acltype=nfsv4 + aclinherit=passthrough means one click in the ACL editor
propagates to the whole future library). Section 7 rewritten now that the
placeholder is gone, section 9 retargeted from dev to prod, section 10 new.
Sections 2/3/4/6 are unchanged by the move.

jakman85andClaude Opus 5 2acfed460a fix(vpn-ingress): content-hash the peer register, or a merged peer never reaches the tunnel
gate / gate (pull_request) Successful in 1m52s
gate / conformance (pull_request) Has been skipped
The operator enrolled a phone, merged the peer, and `wg show` listed none.
Measured on prod 2026-10-06 with the peer already on main:

  live wg-peers ConfigMap, active AllowedIPs .. 0
  DaemonSet volume reference ................. configMap.name: wg-peers (FIXED)
  DaemonSet generation/observedGeneration .... 1 / 1   (never rolled)
  init container, all three pods ............. "0 peer(s)"

Part of it was just the 10m reconcile interval. The defect is the fixed name:
Flux updates a fixed-name ConfigMap IN PLACE, so the pod template is
byte-identical, so no rollout is triggered -- and the init container assembles
wg0.conf ONCE at pod start into a tmpfs, so the running tunnel keeps the old
peer list indefinitely. Adding or revoking a peer had no effect until something
unrelated restarted the pods. For a REVOCATION that is a security defect, not
an inconvenience: delete a stanza, see a green PR, device keeps working.

The runbook and README both claimed "PR -> merge -> Flux rolls the DaemonSet".
Never true. And this repo already documents the fix, in a file I had read --
runbooks/kustomization.yaml: "The generated name carries kustomize's content
hash, so editing any runbook rolls the server automatically and a stale
projection is impossible."

So: peers.yaml (inline ConfigMap) -> peers.conf (plain file) + a
configMapGenerator. The operator's enrolled peer is carried across verbatim.
Every line is WireGuard config and `#` is a legal comment there, so the
documentation now lives inside the file that is actually mounted.

`namespace: vpn-ingress` on the kustomization is REQUIRED, not tidiness: a
generated ConfigMap inherits no namespace, everything else here declares
vpn-ingress, and kustomize's nameReference will not rewrite across a namespace
boundary -- without it the build mounts the unhashed name and the pods wedge on
a missing volume. Caught only by building the output and reading the volumes.

new-peer.sh: PEERS_FILE repointed, and a missing register is now FATAL rather
than skipped -- the old `[ -r "$PEERS_FILE" ] && grep ...` guard meant that
after the rename the only symptom would have been duplicate detection quietly
never firing again. Stale peers.yaml references swept from six files including
the script's own user-facing output.

Verified: the DaemonSet now mounts wg-peers-m9kcckcb5t; the hash tracks content
(edit -> dgg7ht9c74 -> restore -> m9kcckcb5t); the enrolled peer is byte-identical
to main's; and `new-peer.sh dupe 2` is now correctly refused by the operator's
real allocation.

No sensitive paths; merges on a green gate.

jakman85andClaude Opus 5 146dd9a906 fix(vpn-ingress): new-peer.sh counted its own commented-out example as an allocated address
gate / gate (pull_request) Successful in 1m51s
gate / conformance (pull_request) Has been skipped
The first real enrolment failed:

    $ ./infra/vpn-ingress/new-peer.sh keith-phone 2
    new-peer.sh: 10.90.0.2/32 is already allocated ... Pick another octet.

Nothing was allocated -- peers.yaml had zero peers, as the pod's init
container reported (`0 peer(s)`). The duplicate-address check grepped the
whole file, and peers.yaml line 66 is a COMMENTED-OUT example stanza I wrote
containing literally `#   AllowedIPs = 10.90.0.2/32`. So .2 -- the first
address anyone would ask for, and the one my own runbook uses as its example
-- was permanently un-allocatable, with a message asserting the opposite of
the truth.

Fixed on both sides, because either alone leaves the trap half-set:

  * the check strips comment lines before matching, which is the correct
    predicate rather than a patch: a real stanza's AllowedIPs line is never
    commented, while the template and every peer's `# <name> — <owner>` label
    always are.
  * the example now uses placeholders that cannot match anything real
    (`10.90.0.<octet>/32`, `<device-name>`), so a future grep cannot be fooled
    by it either.

The bug class is worth naming: a documentation example that is byte-identical
to real data will eventually be parsed as real data. This is its third
instance in this component -- flux-postbuild-substitution flagged a `${...}`
written inside a comment explaining that hazard, and no-plaintext-secrets
flagged the .sops.yaml.example because a kustomization named it in a comment.
Make examples structurally unmatchable, not merely commented out.

Verified by running it: .2 now renders a profile (via the real
`sops -d | wg pubkey` path, which this also proves against the operator's
actual key for the first time), and an uncommented duplicate stanza is still
correctly refused.

No sensitive paths; merges on a green gate.

branch: fix/new-peer-ignores-template-comments
title: new-peer.sh refused the first VPN address because its duplicate check matched its own commented-out example
---
## What changed
The operator's first real enrolment failed:
```
$ ./infra/vpn-ingress/new-peer.sh keith-phone 2
new-peer.sh: 10.90.0.2/32 is already allocated in platform/vpn-ingress/peers.yaml. Pick another octet.
```
**Nothing was allocated.** `peers.yaml` had zero peers — the pod's own init container reported
`wg0.conf assembled: 0 peer(s)`. The duplicate-address check grepped the WHOLE file, and
`peers.yaml` line 66 is a **commented-out example stanza** I wrote, containing literally
`# AllowedIPs = 10.90.0.2/32`. So `.2` — the first address anybody would ask for, and the one my
own runbook uses in its example — was permanently un-allocatable, with a message asserting the
opposite of the truth.
Both halves fixed, because either alone leaves the trap half-set:
- **`infra/vpn-ingress/new-peer.sh`**: the check strips comment lines before matching
(`grep -vE '^[[:space:]]*#' | grep -q …`). That is the correct predicate rather than a patch: a
real stanza's `AllowedIPs` line is never commented, while both the template and every peer's
`# <name> — <owner>` label always are.
- **`platform/vpn-ingress/peers.yaml`**: the example now uses placeholders that cannot match
anything real — `# <device-name> — <owner>, enrolled <YYYY-MM-DD>` and
`AllowedIPs = 10.90.0.<octet>/32`. A future grep cannot be fooled by it either.
The bug class is worth naming: **a documentation example that is byte-identical to real data will
eventually be parsed as real data.** The same shape caused two earlier defects in this component —
`flux-postbuild-substitution` flagged a `${...}` written inside a comment *explaining* that hazard,
and `no-plaintext-secrets` flagged the `.sops.yaml.example` because the kustomization named it in a
comment. Three instances now; the rule is to make examples structurally unmatchable, not merely
commented out.
No sensitive paths (`platform/vpn-ingress/**`, `infra/vpn-ingress/**`, `decisions/**`), so this
merges on a green gate with no override.
## What I verified
Run in the pinned toolbox against the live tree, 2026-10-06.
- **`.2` now works**, and it went through the REAL key path: `new-peer.sh keith-phone 2` rendered a
profile with `Address 10.90.0.2/32`, `AllowedIPs = 10.90.0.2/32` in the printed stanza, full
tunnel, at `.cache/wg-peers/keith-phone.conf` (0600). The throwaway keypair was deleted after.
- **This incidentally closes a gap left open in #60**: the profile could only have been rendered by
deriving the server's public key via `sops -d --extract … | wg pubkey` from
`wg-server-key.sops.yaml` — so that pipeline is now proven **against the operator's real key**,
not just against a placeholder it was expected to reject.
- **A real duplicate is still refused.** Appending an uncommented
`AllowedIPs = 10.90.0.5/32` stanza and asking for octet 5 produced the correct refusal; the tree
was restored afterwards and `git diff --stat` showed only the intended template edit.
- **Zero active allocations remain**: `grep -vE '^[[:space:]]*#' peers.yaml | grep -c AllowedIPs`
→ `0`.
- **Toolbox gate**: rc 3, with `spec-immutability`, `decisions-log`, `lint`, `l0`, `render-golden`,
`l1` and `approval-policy` all pass; rc 3 is the two environmental skips (`gitea-settings`,
conformance L2/L3). **Not green. Reported as rc 3.**
## What I did NOT verify
- **No peer is enrolled by this branch.** The keypair I generated was a throwaway and was deleted;
the operator must run the script themselves, since the device's private key must exist only on
the device. So the end of the enrolment path — a stanza merged into `peers.yaml`, Flux rolling
the DaemonSet, and `wg show` listing a peer — is still unexercised.
- **The duplicate-NAME warning** (`grep -qi "^ *# *${NAME} "`) deliberately still inspects
comments, because per-peer labels are comments. It is no longer tripped by the template, but I
did not test it against a real enrolled peer.
- **Nothing about client traffic.** The WAN port-forward is still not configured and there is still
no off-LAN vantage point, so the tunnel has carried no packet.

branch: fix/peers-configmap-content-hash
title: A merged VPN peer never reached the tunnel — the peer register was a fixed-name ConfigMap, so nothing rolled the pods
---
## What changed
The operator enrolled a phone, merged the peer, and **`wg show` listed no peers.** Measured on prod
2026-10-06, with the peer already on `main`:
| observation | value |
|---|---|
| peer stanza on `main` | present (`AllowedIPs = 10.90.0.2/32`) |
| GitRepository artifact | `main@sha1:e1bebb8` — Flux had fetched it |
| `vpn-ingress` Kustomization `lastAppliedRevision` | `main@sha1:5928d81` — **behind**, 10m interval |
| live `wg-peers` ConfigMap, active `AllowedIPs` lines | **0** |
| DaemonSet volume reference | `configMap.name: wg-peers` — a **fixed** name |
| DaemonSet `generation` / `observedGeneration` | **1 / 1** — it had **never rolled** |
| init container, all three pods | `wg0.conf assembled: 0 peer(s)` |
The lag was only the reconcile interval. **The defect is the fixed name.** When Flux does update a
fixed-name ConfigMap it updates it *in place*: the DaemonSet's pod template is byte-identical, so
no rollout is triggered — and because the init container assembles `wg0.conf` **once at pod start**
into a tmpfs, the running tunnel keeps the old peer list indefinitely. Adding or revoking a peer
would have had **no effect at all** until something unrelated happened to restart the pods. For a
*revocation* that is a security defect, not an inconvenience: the operator would delete a stanza,
see a green PR, and the device would keep working.
My runbook and README both asserted "PR → merge → Flux rolls the DaemonSet (~1 min)". That was
never true.
**This repo already documents the fix, and I had read the file.** `runbooks/kustomization.yaml`:
*"The generated name carries kustomize's content hash, so editing any runbook rolls the server
automatically and a stale projection is impossible."*
So the register becomes a **content-hashed generator**:
- `platform/vpn-ingress/peers.yaml` (inline ConfigMap) → **`platform/vpn-ingress/peers.conf`**, a
plain file, plus a `configMapGenerator` in `kustomization.yaml`. The operator's enrolled peer was
carried across verbatim. Every line is WireGuard config and `#` is a legal comment there, so the
documentation now travels *inside the mounted file* instead of in a YAML wrapper that gets
stripped.
- **`namespace: vpn-ingress` added to the kustomization — REQUIRED, not tidiness.** A generated
ConfigMap inherits no namespace; every other object here declares `vpn-ingress`; and kustomize's
`nameReference` transformer will not rewrite a reference across a namespace boundary. Without it
the build emitted `ConfigMap wg-peers-m9kcckcb5t` while the DaemonSet still mounted the unhashed
`wg-peers`, which would not exist — the pods would wedge on a missing volume. I caught this only
by building the output and reading the volumes block.
- **`infra/vpn-ingress/new-peer.sh`**: `PEERS_FILE` repointed to `peers.conf`, and a missing
register is now **fatal** instead of skipped. The old guard was
`[ -r "$PEERS_FILE" ] && grep …`, so after the rename the only symptom would have been
duplicate-address detection quietly never firing again — the silent-skip shape this repo treats
as a defect in its own right.
- Stale `peers.yaml` references swept from the README, runbook, `daemonset.yaml`,
`networkpolicy.yaml`, the SOPS example, and the script's own **user-facing output** (it told the
operator to paste into "peers.yaml, under data.peers.conf", which would no longer exist).
- The runbook gained the verification that actually distinguishes this failure — the DaemonSet's
`generation` must *increase* after the merge — and a troubleshooting row for `0 peer(s)` after a
merge.
Flux's `prune: true` removes the orphaned fixed-name `wg-peers` ConfigMap on the next reconcile.
No sensitive paths (`platform/vpn-ingress/**`, `infra/vpn-ingress/**`, `runbooks/**`,
`decisions/**`), so this merges on a green gate with no override.
## What I verified
Built and run in the pinned toolbox, 2026-10-06 (kustomize v5.8.1 via `kubectl kustomize`).
- **The reference is now rewritten end to end**: generated `ConfigMap wg-peers-m9kcckcb5t` in
namespace `vpn-ingress`, and the DaemonSet mounts **`wg-peers-m9kcckcb5t`**. Before adding
`namespace:` the same build mounted the unhashed `wg-peers` — so the namespace line is load
bearing, measured both ways.
- **The hash tracks content, which is the whole mechanism.** `wg-peers-m9kcckcb5t` →
append a second peer → `wg-peers-dgg7ht9c74` → restore → `wg-peers-m9kcckcb5t`. Deterministic
and reversible, so an edit necessarily changes the pod template.
- **The operator's enrolled peer survived the file conversion byte-for-byte**: the active stanza in
`peers.conf` (`PublicKey = pBRSHrRy…`, `AllowedIPs = 10.90.0.2/32`) is identical to the one on
`main`, compared directly against `git show origin/main:platform/vpn-ingress/peers.yaml`.
- **The build still emits all five objects**: Namespace, ConfigMap, Secret, DaemonSet,
NetworkPolicy — and the `Namespace` object's own name is still `vpn-ingress` (the namespace
transformer did not rewrite it).
- **`new-peer.sh` works against the new register**: `spare-laptop 7` renders a profile and prints
"append this to platform/vpn-ingress/peers.conf"; `dupe 2` is **refused** because the operator's
real `.2` now occupies it — the first time the duplicate check has been exercised against real
data rather than against its own example.
- **Toolbox gate**: rc 3, with `spec-immutability`, `decisions-log`, `lint`, `l0`, `render-golden`,
`l1` and `approval-policy` all pass; rc 3 is the two environmental skips. **Not green. Reported
as rc 3.**
## What I did NOT verify
- **That the roll actually happens on the cluster.** The whole point of the change is unproven
until Flux applies it: the success criterion is the DaemonSet's `generation` increasing and
`wg0.conf assembled: 1 peer(s)` in the init log, followed by `wg show` listing the peer.
- **That the tunnel then carries traffic.** No handshake has ever been observed. The WAN
port-forward is reportedly configured but has never been exercised by a packet I can see, and I
have no off-LAN vantage point — runbook step 6 from cellular remains the only honest test.
- **Revocation**, which is the case where this defect was a security problem. Deleting a stanza
should now roll the pods and drop the peer; untested.
- **Whether the orphaned fixed-name `wg-peers` ConfigMap is actually pruned.** Reasoned from
`prune: true` on the Kustomization, not observed.

branch: fix/bulk-nfs-truenas
title: Repoint bulk NFS at the TrueNAS (192.168.2.30); the PVs must be recreated, not reconciled
---
## What changed
Both ZFS pools were physically moved off the Proxmox host onto a standalone TrueNAS Community
Edition at **192.168.2.30**, which sits on prod's own `192.168.2.0/24`. `BULK_NFS_SERVER` moves from
`192.168.2.102` (the pfSense DNAT prod used to mount through) to `192.168.2.30`.
- `clusters/prod/kustomization.yaml` — `BULK_NFS_SERVER` → `192.168.2.30`. The comment block that
justified the DNAT, and the "NOT YET DECIDED / THIS PLACEHOLDER IS LOAD-BEARING" banner, are
replaced with the measured export configuration and the recreate requirement below.
- `clusters/base/cluster-vars.yaml` — base default `192.168.1.9` → `192.168.2.30`. That host no
longer exists.
- `clusters/dev/kustomization.yaml` — same; marked explicitly **inert**, since dev is decommissioned
and its nodes are gone. It carries the real address only so nothing in the tree renders a dead one.
- `docs/BULK-NFS-STORAGE.md` — §1 and §5 rewritten for TrueNAS (exports, service settings, the ZFS
`sharenfs` properties that had to be cleared, and the ACL hazard); §7 rewritten now that the
placeholder is gone; §9 retargeted from dev to prod; **new §10** documents the PV
delete-and-recreate. §2/§3/§4/§6 are unchanged by the move.
- `catalog/qbittorrent.yaml`, `platform/monitoring/node-pressure-dashboard.yaml` — two comment/prose
references to `192.168.2.102` as the live export address.
**The headline operational fact: repointing this knob is NOT a plain reconcile.** A bound PV's NFS
source is immutable, so Flux's apply fails rather than updating and the pods keep their old, dead
mount. The five PVs must be deleted and recreated. That sequence is §10 and is an operator action;
it is **not** performed by this PR.
## What I verified
**On the NAS (192.168.2.30), measured 2026-10-07 by the operator at my request:**
- `zfs list` — `Storage` → `/mnt/Storage`, `Storage/plex` → `/mnt/Storage/plex`,
`Storage/nextcloud` → `/mnt/Storage/nextcloud`. The PV paths resolve unchanged.
- Ownership intact: `/mnt/Storage/plex`, `tv/`, `downloads/`, `movies/`,
`downloads/complete/`, `nextcloud/nextcloud/` all `drwxr-xr-x 1000:3000`. `movies/` 1171 entries
and `tv/` 107, against 1165 / 107 measured on Proxmox.
- `acltype=nfsv4` (SCALE's built-in default, `SOURCE: default`), `aclinherit=passthrough`, and no
non-trivial ACLs — mode bits still govern.
- Three stale `sharenfs` dataset properties (`plex`, `nextcloud`, `docker-volumes`) carried over from
Proxmox; cleared with `zfs inherit`, re-checked empty.
- `exportfs -v`: both shares to `192.168.2.10/.11/.12` with `sec=sys,secure,root_squash,no_all_squash`,
`rw` on plex and `ro` on nextcloud.
- `/proc/fs/nfsd/versions` → `+3 +4 +4.1 +4.2`, so the PVs' `nfsvers=4.1` negotiates.
- **A defect was found and fixed during setup:** the plex share listed `192.168.2.13` — an address no
node holds — and so omitted `192.168.2.12` (k3s-prod-3). Corrected and re-verified.
**From the cluster:**
- Node InternalIPs are `192.168.2.10/.11/.12` (`kubectl get nodes`), confirming `.13` was wrong.
- All five NFS PVs currently name `192.168.2.102`.
- `192.168.2.30:2049` and `:111` accept connections; `192.168.2.102:2049` does not.
- **`spec.nfs` immutability, by server-side dry-run** — this is the finding that shapes the change:
`spec.persistentvolumesource: Forbidden: spec.persistentvolumesource is immutable after creation`.
- The pods report `Ready` while their mounts are dead: a `stat /media` answers from attribute cache,
but a `readdir` blocks indefinitely (the PVs mount `hard`). Hence "scale to zero first" in §10.
**Gate:** see the PR; run in the pinned toolbox from this worktree.
## What I did NOT verify
- **Nothing has mounted 192.168.2.30.** No pod has touched the new server — the PVs still point at
the old address and cannot be updated in place. Every §9 probe (numeric-id passthrough, the uid-1000
write, the hardlink/EXDEV check, Plex's read-only posture) is **outstanding**, not passing. The
equivalents passed against the old host on 2026-09-12; that is not evidence about this one.
- **The §10 sequence is reasoned, not executed.** Retain + the renderer's pre-set `claimRef` are read
from the manifests and from `catalog/render.py`; I have not watched a PVC rebind after a PV delete
in this cluster.
- **`root_squash` is a behaviour change from the Proxmox export**, which carried `no_root_squash`. The
argument that nothing needs root on the tree (LSIO drops to 1000; the images chown only their
Longhorn `/config`; both subPath directories already exist at 0755) is reasoned from the images and
the measured permissions. It has not been exercised. If a mount or subPath resolution fails with
EACCES, Maproot `root:root` reproduces the old export and is the first thing to try.
- **Whether NFSv3 can be disabled.** Enabled Protocols is `NFSv3, NFSv4`; the PVs only need v4.1, so
narrowing would close the rpcbind/mountd/statd surface. Not done — it is a change to make after the
cutover is proven, not during it.
- **Whether pfSense / the legacy stack is actually retired.** I measured only that
`192.168.2.102:2049` stopped answering. The other legacy consumers of these datasets
(`192.168.1.6`, `10.123.1.10`, `192.168.1.18`) were dropped from the new exports; if any is still
live, it has lost access. Not checked.
- **L2/L3 conformance.** `vars.CLUSTER_AVAILABLE` is unset, so CI proves the L0/L1 offline subset
only. Nothing in the gate exercises an NFS mount.

branch: fix/oauth2-proxy-oidc-startup-race
title: "oauth2-proxy dies on a cold start because OIDC discovery runs once, before Keycloak serves"
---
## What changed
Exposed by the 2026-10-17 whole-cluster shutdown for the UPS move. oauth2-proxy performs OIDC
discovery **once, at startup**, and `os.Exit(1)`s if it fails. On a cold boot Keycloak is not
serving yet, so the shared Gateway answers 503 and the proxy dies:
```
[provider.go:55] Performing OIDC Discovery...
[main.go:73] ERROR: Failed to initialise OAuth2 Proxy: error initialising provider: ...
failed to discover OIDC configuration: unexpected status "503": no healthy upstream
```
It then sits in **exponential CrashLoopBackOff long after Keycloak is healthy** — one of the two
replicas was still down minutes later and only a manual `kubectl delete pod` cleared it. There is no
retry flag; the process does not survive a cold start. A readinessProbe cannot help (the container
is already dead), and CrashLoopBackOff backoff is not tunable per-pod.
`platform/oauth2-proxy/helmrelease.yaml` gains an `extraInitContainers` gate (`wait-for-idp`) that
polls Keycloak's discovery doc until it answers, then lets the proxy start. A pod in `Init` does not
accrue CrashLoopBackOff backoff and retries promptly, which is the point.
**Bounded, and fails open.** After ~5 minutes it gives up and starts the proxy anyway, so the worst
case is exactly today's behaviour and never something new. An unbounded wait would trade a CrashLoop
for a pod wedged in `Init` forever, which is not an improvement.
## Why this shape and not the alternatives
* **`extraInitContainers` is the chart's own documented hook for precisely this.** Its commented
example in `values.yaml` is literally `- name: wait-for-idp`. The key was **confirmed against the
pinned chart** (`helm show values oauth2-proxy/oauth2-proxy --version 10.7.1` → `extraInitContainers: []`
at line 428), not assumed — a wrong Helm values key is silently ignored, which is the
"reviewed, merged, apparently done, still broken" shape this repo keeps getting bitten by.
* **No new base image.** The chart already runs an `alpine` init container for its built-in
`initContainers.waitForRedis` gate, so alpine is a base this chart uses regardless. Pinned to
`3.22` (verified to exist upstream) rather than the chart's own `latest`.
* **Flux `postRenderers` rejected:** it would work independently of the chart schema, but nothing in
this tree uses postRenderers, so it would introduce a mechanism with no precedent for a problem
the chart already has a hook for.
* **`--skip-oidc-discovery` rejected:** it removes the startup fetch entirely, which is arguably
more elegant, but it means hardcoding four Keycloak endpoints and I could not verify offline that
oauth2-proxy then fetches JWKS lazily rather than at startup. oauth2-proxy gates SSO for PiHole,
the \*arr apps, qBittorrent, Homepage, Prometheus, Alertmanager and Hubble — a wrong guess locks
the operator out of all of them, so the reversible, additive option wins.
The `$$`-free convention matters here: shell variables are written bare (`$i`, `$url`, `$(( ))`)
with **no braced form anywhere**, because `platform` declares `postBuild.substituteFrom cluster-vars`
and envsubst consumes braced expansions — a braced shell variable renders to the empty string and
silently breaks the loop. `${BASE_DOMAIN}` is braced on purpose. Same hazard and same convention as
the gitea and nextcloud OIDC bootstrap hooks, and `ci: flux-postbuild-substitution` enforces it.
## What I verified
* **The failure is measured, not theorised.** The log above is from the live pod
(`oauth2-proxy-5d6c74876b-bzb2p`, `lastState.terminated: {reason: Error, exitCode: 1}`), captured
with `--previous` after the cold boot. The surviving replica's log shows the same startup
succeeding once Keycloak was up, which is what identifies this as a race rather than a config
fault.
* **Deleting the pod is a sufficient workaround** — done on prod 2026-10-17, the replacement came up
clean and both replicas have been healthy since.
* **The chart key is real**, at the pinned version range: `helm search repo` resolves
`>=10.0.0 <11.0.0` to chart `10.7.1` (app `7.15.5`), whose values carry `extraInitContainers: []`,
`extraContainers: []` and the built-in `initContainers.waitForRedis` (which uses `alpine`).
* **`docker.io/library/alpine:3.22` exists** — confirmed against the registry tag list rather than
assumed from memory.
* The edited HelmRelease parses as YAML.
## What I did NOT verify
* **UNAPPLIED. The init container has never run.** I did not reconcile the HelmRelease, so I have not
seen `wait-for-idp` execute, exit 0, or gate the proxy. Applying it rolls both oauth2-proxy
replicas, which is a mutating action (CLAUDE.md §5) — and it rolls the component that gates SSO for
seven apps, so **do it when you can watch it**, not unattended.
* **I did not re-create the cold-start race to prove the fix.** That needs Keycloak down while
oauth2-proxy starts; the honest test is the next whole-cluster boot. Until then this is reasoned
from the measured failure, not demonstrated against it.
* **busybox `wget`'s TLS behaviour here is assumed, not tested.** The claim is that alpine's
`ca-certificates-bundle` lets it validate the Gateway's LE-prod certificate, so a genuine TLS
failure exits non-zero rather than passing falsely. If that is wrong in either direction the gate
degrades safely — a never-succeeding probe just burns the 5-minute budget and then starts the proxy
anyway — but the fast path would be silently dead and this would be doing nothing. **Check the
init container's log on first apply**: it should print "Keycloak discovery reachable" within
seconds on a warm cluster, not the give-up message.
* **Whether a pod can reach the Gateway hostname at all from this namespace is inherited, not
re-proven.** The main container does exactly this fetch today and succeeds, so the path is known
good — but note the standing trap that an arbitrary pod gets 403 from every Gateway hostname
(`decisions/2026-10-04-plex-advertise-plexdirect.md`); oauth2-proxy is exempt only because
Keycloak's ingress policy admits it. An init container in the same pod inherits that identity, so
this should hold — unverified.
* **60 attempts x 5s is not tuned.** It is "comfortably longer than Keycloak's observed cold start",
not a measured bound.
* **No runtime conformance.** `vars.CLUSTER_AVAILABLE` is unset, so CI proves the L0/L1 offline
subset only.
* I did not re-measure branch protection or runner state (CLAUDE.md §2b).

`192.168.2.0/24` as prod's nodes (`192.168.2.10/.11/.12`), so it is reached directly, with no NAT
and no routing decision.

Opening the storage path for prod is a **pending operator decision**. Its two candidate outcomes give
different values for the `BULK_NFS_SERVER` cluster-var:
| outcome | `BULK_NFS_SERVER` for prod |
|---|---|
| port-forward `192.168.2.102:2049` → `192.168.1.9:2049` | `192.168.2.102` |
| a WAN→LAN route to 192.168.1.0/24 | `192.168.1.9` |
Until it lands, `clusters/prod` holds `TBD-PROD-BULK-NFS-SERVER`. **See §7 for why that placeholder
behaves differently from the repo's other ones.**
**This section used to be the hard part of this page.** The datasets were on the Proxmox host, whose
only interface was `vmbr0 192.168.1.9/24` on pfSense's **LAN**, while prod sits on pfSense's **WAN**.
tcp/2049 did not traverse that, so prod mounted through a DNAT at `192.168.2.102`, and which address
belonged in `BULK_NFS_SERVER` depended on an undecided operator choice. Both pools were physically
moved on 2026-10-07 (`docs/plans/proxmox-to-n5-air-migration.md`, Phase C/D) and all of that is
simply gone. Measured 2026-10-07: **192.168.2.102:2049 no longer answers; 192.168.2.30:2049 and
:111 do.**
### It only needs ONE port
The PVs mount `nfsvers=4.1`. **NFSv4 carries mount and lock in-protocol**, so the only thing that
must be reachable is **tcp/2049** — no rpcbind/111, no mountd, no statd. NFSv3 would have needed
four ports, three of them on ephemeral numbers, which is a materially worse firewall story. The
server advertises `+3 +4 +4.1 +4.2` (`/proc/fs/nfsd/versions`), so v4.1 is available and is the
conservative floor.
four ports, three of them on ephemeral numbers. The NAS advertises `+3 +4 +4.1 +4.2`
(`/proc/fs/nfsd/versions`, measured 2026-10-07), so 4.1 is available and is the conservative floor.
### The export's client list is the SAME under both outcomes — measured, not assumed
**pfSense DNATs the existing port-forward WITHOUT source NAT.** Connecting from this workstation
(192.168.2.132) to `192.168.2.102:22`, the storage host logged the peer as `192.168.2.132`:
```
SSH_CONNECTION=192.168.2.132 39768 192.168.1.9 22
ss -tn -> 192.168.1.9:22 192.168.2.132:39768
```
The original WAN-side source address survives the translation (return traffic finds its way back via
the host's default route, 192.168.1.1). So under **either** outcome the NFS server will see prod's
**real** node addresses — 192.168.2.10/.11/.12 — and the `sharenfs` change in §5 is the same either
way. **It does not have to wait for the routing decision.**
---
**NFSv4 is not on by default and its absence does not look like a storage problem.** TrueNAS ships
NFSv3-only until NFSv4 is added to *Services → NFS → Enabled Protocols*. Without it the mount never
completes and the pods sit in `ContainerCreating` — no permission error, nothing in the app logs,
just no volume.

### The exports

### `Storage/plex` — append the six k3s node addresses to the existing `rw=` list
Per-node addresses rather than `@192.168.2.0/24`, following the precedent of the old host. A `/24`
would work and would survive adding a node; it also grants the whole subnet.
**All three nodes must appear on BOTH shares.** Any media pod can be scheduled on any node, so a
missing node is a latent failure, not an immediate one: it surfaces the first time a pod reschedules
there, as `access denied by server while mounting`, with the cause weeks stale. One was caught
exactly this way during setup — the plex share listed `192.168.2.13`, an address no node holds, and
so was missing `192.168.2.12` (k3s-prod-3). Nothing was failing at the time.
### The option flags ARE the permission contract
| flag | why it matters here |
|---|---|
| **`no_all_squash`** | The one the whole model rests on. Client uids pass through untouched, so the arrs' `PUID=1000` arrives as the owner of a `0755 1000:3000` tree. In the UI this is **Mapall User/Group left EMPTY** — setting either squashes every client to one identity and erases the reader/writer distinction entirely. |
| **`sec=sys`** | AUTH_SYS. Numeric uid/gid, not Kerberos principals. §6 is only true because of this. |
| **`root_squash`** | Maproot left empty. The Proxmox export carried `no_root_squash`; **nothing here needs it** — every write to the tree happens after the LSIO drop to uid 1000, and the images only chown their Longhorn `/config`. This is a deliberate tightening over the old export, not parity. |
| **`rw` / `ro`** | The archive's read-only posture is **server-enforced**, as it was before. The media tree cannot get the same treatment — see below. |
| **`secure`** | Reserved source ports required; "Allow non-root mount" off. The kubelet mounts as root from a reserved port and does not need the exception. |
**Plex's read-only posture is still a CLIENT-side guarantee.** Plex is ro and the arrs are rw, but
all four can land on any node, so the server sees the same three source addresses for all of them
and cannot distinguish the reader from the writers. `spec.nfs.readOnly: true` on `plex-media` plus
the volumeMount flag is the whole enforcement. Unchanged by the move; an honest limitation, not an
oversight. If it ever needs to be server-enforced, the lever is a dedicated node pool for Plex.
### Service settings that are NOT obvious from the export list
- **Enabled Protocols must include NFSv4** (above).
- **Require Kerberos for NFSv4: off.** The numeric AUTH_SYS pass-through is the model.
- **Manage Groups Server-side: off.** This is `rpc.mountd --manage-gids`: the server *discards the
client's supplied group list* and looks that uid's groups up in TrueNAS's own user database
instead. With no local uid 1000 defined, the arrs' `PGID=3000` would simply vanish. Writes would
survive anyway — uid 1000 **owns** the tree, so the owner bits grant access without the group —
but it is a free way to lose group semantics.
- **NFSv4 DNS Domain: blank.** It only feeds `idmapd.conf`, which numeric mapping bypasses.
- **Bind IP 192.168.2.30** means loopback does not answer: check with `showmount -e 192.168.2.30`,
not `localhost`.
There is **no** "NFSv3 ownership model for NFSv4" control on current TrueNAS — it was an older
TrueNAS/CORE option, and no replacement is needed: on a Linux client against a Linux server over
AUTH_SYS, both the `nfs` and `nfsd` modules default to `nfs4_disable_idmapping=Y`, so NFSv4 carries
raw numeric ids rather than `user@domain` principals. §9's `ls -n` probe is how you confirm it.
### The ZFS `sharenfs` properties must be CLEARED, not edited
The pools arrived with the old host's exports still set as dataset properties:
```
Storage/plex [email protected]:@10.123.1.10:@192.168.1.18:@192.168.2.10:@192.168.2.11:@192.168.2.12,no_subtree_check,no_root_squash

```
TrueNAS generates `/etc/exports` from its own middleware database and will fight a property it did
not set — the failure mode is two differently-configured exports of one path, with no indication
which is in force. Cleared 2026-10-07:
```sh
zfs set sharenfs='[email protected]:@10.123.1.10:@192.168.1.18:@192.168.1.40:@192.168.1.41:@192.168.1.42:@192.168.2.10:@192.168.2.11:@192.168.2.12,no_subtree_check,no_root_squash' Storage/plex

zfs inherit sharenfs Storage/nextcloud
zfs inherit sharenfs Storage/docker-volumes
```
Every pre-existing host is preserved verbatim and no option changes; only clients are added.
`Storage` is `off`, so each resolves to `off`.
### `Storage/nextcloud` — add the k3s nodes to a **`ro=`** list, not to `rw=`
### Do NOT touch the dataset's permissions or ACLs
```sh
zfs set sharenfs='[email protected]:@192.168.1.5,[email protected]:@192.168.1.41:@192.168.1.42:@192.168.2.10:@192.168.2.11:@192.168.2.12,no_subtree_check,no_root_squash' Storage/nextcloud
```
The tree's ownership **is** the access story (§6), and TrueNAS offers two ways to destroy it
irreversibly across 8.33 T.
This is the one place read-only can be enforced **server-side**, and it is worth taking: only
Nextcloud consumes this dataset from k3s, so the export itself can refuse writes. Even a
misconfigured client cannot then damage the archive.
`Storage/plex` carries `acltype=nfsv4` (SCALE's built-in default, `SOURCE: default`) and
`aclinherit=passthrough` (inherited). Measured 2026-10-07: the directories carry **trivial ACLs
only** — `nfs4xdr_getfacl` shows just `owner@`/`group@`/`everyone@` matching the mode — so `0755
1000:3000` governs exactly as it did under Proxmox.
**The media tree cannot get the same treatment.** Plex is read-only and the arrs are read-write, but
all three may be scheduled on any node, so the server sees the same source addresses for all of
them and cannot distinguish the reader from the writers. **Plex's read-only posture is therefore a
client-side guarantee** (`spec.nfs.readOnly: true` on `plex-media`, plus the volumeMount flag) — an
honest limitation, not an oversight. If it ever needs to be server-enforced, the lever is a
dedicated node pool for Plex, which is a much larger change.
- **Stay out of the dataset's Edit Permissions / Edit ACL screen.** On an `acltype=nfsv4` dataset
that is a full ACL editor, and its presets write *real* NFSv4 ACLs, recursively if permitted.
There is no undo.
- `aclinherit=passthrough` means a single ACL written at `/mnt/Storage/plex` would be **inherited by
everything created under it afterwards** — the blast radius is the whole future library, not one
directory.
- Note GNU `ls`'s `+` marker is **not** a reliable ACL indicator here: it looks for a POSIX ACL
xattr, and this dataset stores NFSv4 ACLs elsewhere. Use `nfs4xdr_getfacl`.
Per-node addresses rather than `@192.168.2.0/24` follows the precedent already on this host
(`/etc/exports` lists the dev nodes individually, as `/32`). A `/24` would work and would survive
adding a node; it also grants the whole subnet. Per-node is the tighter default.
`xattr=on` rather than `sa` is a performance detail, not a permissions one, and changing it would
not affect existing files.
### Verifying, without changing anything
```sh
exportfs -v # the new client lines appear, existing ones unchanged
zfs get sharenfs Storage/plex Storage/nextcloud
cat /proc/fs/nfsd/versions # +4.1 must be present

## 10. Repointing BULK_NFS_SERVER means DELETING AND RECREATING THE PVs
**A bound PersistentVolume's NFS source is immutable.** Measured by server-side dry-run on
2026-10-07:
```
$ kubectl patch pv sonarr-media --type=json --dry-run=server \
-p '[{"op":"replace","path":"/spec/nfs/server","value":"192.168.2.30"}]'
The PersistentVolume "sonarr-media" is invalid: spec.persistentvolumesource: Forbidden:
spec.persistentvolumesource is immutable after creation
```
Note the pairing with §7: `spec.nfs.server` is **unvalidated at create** (any string is accepted and
the PVC binds) and **immutable at update**. So editing `BULK_NFS_SERVER` alone does not fail loudly
and does not work either — Flux's apply errors on the five PVs and the pods keep their previous,
now-dead mount.
This is safe to do because `persistentVolumeReclaimPolicy: Retain` means deleting a PV never touches
the data, and `catalog/render.py` emits a **pre-set `claimRef`** on each one, so a recreated PV
rebinds its own PVC with no manual step.
**Operator sequence** (mutating `kubectl` is an operator action, not an agent action):
```sh
# 1. Stop the consumers. This also releases the hung hard-mounts against the old server:
# the pods report Ready, but any real I/O on /media blocks indefinitely once 2049 stops
# answering, because the PVs mount `hard`.
for ns in plex sonarr radarr qbittorrent nextcloud; do
kubectl --context k3s-prod -n $ns scale deploy --all --replicas=0

# still down minutes later and only a manual pod delete cleared it. There is no retry flag; the

# already dead), and CrashLoopBackOff backoff is not tunable per-pod.
#
# `extraInitContainers` is the chart's OWN documented hook for this -- its commented example in
# values.yaml is literally `- name: wait-for-idp` -- and the chart already uses an alpine init
# container for its built-in waitForRedis gate, so this adds no new base image to the platform.
