# Plex plex.tv server-claim token (WS-APPS). SOPS-encrypted (age).
# Consumed by catalog/plex.yaml as env PLEX_CLAIM via valueFrom.secretKeyRef.
#
# NOTE ON THESE COMMENTS: they carry NO dollar-brace expressions, deliberately. This file is applied
# by the apps-wave-0 Flux Kustomization, which runs envsubst over the built output, and kustomize
# preserves body comments into that stream (see conformance/tests/l0-static/flux-postbuild-
# substitution). A braced token quoted from the upstream shell script would be a live hazard here,
# not prose, so the upstream conditions below are described in words.
#
# THE VALUE SHIPPED WITH THIS FILE IS A PLACEHOLDER, DELIBERATELY — the literal string
# `replace-me-with-a-fresh-plex-tv-claim-token`, not a credential. A https://plex.tv/claim token has
# a ~4-minute TTL, far shorter than commit -> push -> Flux reconcile -> pod-roll, so no token
# committed here is ever still valid when the pod starts. This file exists to make the Secret — and
# therefore the env reference — ALWAYS RESOLVABLE IN THE FLUX GRAPH, not to carry a working token.
# The real token is injected by the operator inside that 4-minute window: runbooks/plex-claim.md.
#
# WHY SHIPPING A PLACEHOLDER IS SAFE (verified against plexinc/pms-docker branch `master`, the
# s6-overlay v2 script root/etc/cont-init.d/40-plex-first-run, cross-checked byte-identical against
# the same file extracted from the running `plexinc/pms-docker:latest` image):
# - line 106 guards the claim exchange on TWO conditions: PLEX_CLAIM non-empty AND the
# PlexOnlineToken pref read out of /config empty. Once the server is claimed that block is
# skipped entirely, so whatever this Secret holds is a NO-OP on every later start. Upstream
# README: "If server is already logged in, this parameter is ignored."
# - on a still-UNCLAIMED /config, an invalid or expired token makes plex.tv answer 403 with an
# empty body. curl's exit status is never checked, the sed for the authentication-token element
# yields the empty string, and the success branch at line 120 simply does not fire. There is no
# else branch and no non-zero exit; the script has no `set -e` and ends by touching
# /.firstRunComplete and echoing, so it exits 0. The server comes up UNCLAIMED and serving.
# It does NOT crashloop.
# - the image never sets S6_BEHAVIOUR_IF_STAGE2_FAILS, whose default is 0 ("continue silently even
# if a cont-init script failed"), so even a hypothetical non-zero exit would not halt startup.
# A MISSING Secret would NOT be safe: the ServiceDefinition schema's valueFrom.secretKeyRef shape
# has no `optional` field, so an absent Secret is a hard CreateContainerConfigError. That is exactly
# why this file is committed and listed in apps/wave-0/kustomization.yaml instead of being created
# by hand at claim time.
#
# INJECTION / ROTATION (operator, not agents) — runbooks/plex-claim.md has the timed procedure:
# infra/devcontainer/dev.sh run sops apps/wave-0/plex-claim-secret.sops.yaml
# Never decrypt this file into a shell, a log, or a shared terminal.

# PLEX_CLAIM — the ONE-SHOT plex.tv server claim, sourced from the SOPS Secret `plex-claim`
# (apps/wave-0/plex-claim-secret.sops.yaml, same wave => applied in the same reconcile as this

# UNCLAIMED, so this is wired; it was previously left out on the reasoning below, and only one
# half of that reasoning survived contact with the upstream source.

# THE 4-MINUTE TTL IS STILL TRUE, and it is now the OPERATIONAL constraint rather than a reason to
# abstain. A https://plex.tv/claim token expires in ~4 minutes — far shorter than commit -> push ->

# - the exchange (line 106) is guarded on TWO conditions: PLEX_CLAIM non-empty AND the
# PlexOnlineToken pref in /config empty. Once claimed, the block is SKIPPED — this env is a
# no-op on every subsequent start, whatever it holds. (Upstream README: "If server is already
# logged in, this parameter is ignored.") The claim itself persists on the /config PVC as before.
# - an invalid/expired token on a still-unclaimed /config gets a 403 with an empty body; curl's

# default 0, which continues startup even when a cont-init script fails.
# So the earlier "a placeholder claim Secret would crashloop the pod" note was WRONG about the
# placeholder; it was right only about an ABSENT Secret. secretKeyRef here has no `optional` field,

# plex-claim — claiming the Plex Media Server inside the 4-minute token window
**Alert:** none. This is an **operator procedure**, not an incident page — it is indexed here because
it is the page you need at the moment you need it, with a stopwatch running.
**Files:** `catalog/plex.yaml` (env `PLEX_CLAIM`), `apps/wave-0/plex-claim-secret.sops.yaml`
(the SOPS Secret `plex-claim`, key `PLEX_CLAIM`), `apps/wave-0/plex.yaml` (the rendered golden).
## What this means here
Plex will not let you **create libraries** over the mounted bulk media share while the server is
**unclaimed** — the 8.33 T NFS tree at `/media` is there, readable, and unusable. Claiming binds the
server to a plex.tv account. It is a **one-shot** operation: the token is exchanged once for a durable
`PlexOnlineToken` written into `Preferences.xml` on the `plex-config` Longhorn PVC, and from then on
the `PLEX_CLAIM` env is **ignored on every start** (upstream gate:
`[ ! -z "${PLEX_CLAIM}" ] && [ -z "${token}" ]` in `root/etc/cont-init.d/40-plex-first-run`).
**A `https://plex.tv/claim` token lives ~4 minutes.** That is shorter than commit → push → Flux's
10-minute reconcile interval → pod roll if you let those run on their own timers, which is why this
page exists: every step below is written to be run back-to-back, with the reconcile **forced** rather
than waited for. Budget: token in hand at T+0, pod restarted by roughly T+2:00.
**An expired or wrong token does not break anything.** Verified against the image's own first-run
script (and the copy inside `plexinc/pms-docker:latest`): a failed exchange gets a 403 with an empty
body, `curl`'s status is never checked, the token `sed` yields empty, the `if` does not fire, there is
no `else` and no `exit 1`, and the script (no `set -e`) exits 0. The pod comes up **unclaimed and
serving**. So a burnt token costs you one more attempt, not an outage — and the repo deliberately
ships a **placeholder** in that Secret for exactly this reason (the env `secretKeyRef` has no
`optional`, so the Secret must always exist even when its value is useless).
## Running the commands in this runbook
`kubectl` does not work on the operator workstation. The toolchain lives only in the pinned dev
container, and the host's `k3s-oidc` context hangs on a browser prompt once its token expires — that
hang is not the cluster being down. Every command below runs as:
infra/devcontainer/dev.sh run bash -c 'kubectl --context k3s-prod get nodes'
Always pass `--context k3s-prod` explicitly. `dev.sh` merges BOTH clusters into one kubeconfig and
picks a current-context per invocation, and that default has already changed once (k3s-dev until dev
was decommissioned on 2026-09-13, k3s-prod now). Do not run two `dev.sh` invocations at once.
Mutating `kubectl` and `flux reconcile` are blocked for agents here. **This whole page is operator
work** — the reconcile and the pod roll below are deliberate operator actions, and the durable change
is still a git change.
## First commands
**Before spending a token, find out whether the server is already claimed.** This prints only the
attribute NAME, never its value — do not widen it to print the token:
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex exec deploy/plex -- sh -c \
"grep -o PlexOnlineToken= \"/config/Library/Application Support/Plex Media Server/Preferences.xml\" | head -1"'
```
`PlexOnlineToken=` printed ⇒ **already claimed**; stop, there is nothing to do and no token to burn.
Empty output ⇒ unclaimed, continue.
Is the workload healthy enough to claim at all, and is the wave reconciling?
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex get deploy,pod,pvc'
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n flux-system get kustomization apps-wave-0'
```
## The 4-minute procedure
Have this page open and do not stop between steps.
1. **T+0 — get the token.** Sign in to plex.tv as the account that should OWN this server, open
<https://plex.tv/claim>, copy the `claim-…` string. The clock starts now.
2. **T+0:15 — put it in the Secret**, in place, encrypted, without it ever touching a plaintext file:
```
infra/devcontainer/dev.sh run sops apps/wave-0/plex-claim-secret.sops.yaml
```
Replace the `PLEX_CLAIM:` value (the placeholder `replace-me-with-a-fresh-plex-tv-claim-token`, or
a previous expired token) and save. `sops` re-encrypts on write to the committed age recipient.
3. **T+0:45 — commit and push.** `git push origin main` **is** the deploy; there is no other apply
step.
```
git add apps/wave-0/plex-claim-secret.sops.yaml
git commit -m 'chore(plex): fresh plex.tv claim token'
git push origin main
```
4. **T+1:00 — force the reconcile immediately. This is the one command that saves the window** — it
pulls the new commit and re-applies wave 0 instead of waiting up to 10 minutes for the interval:
```
infra/devcontainer/dev.sh run bash -c \
'flux --context k3s-prod -n flux-system reconcile kustomization apps-wave-0 --with-source'
```
`--with-source` is the load-bearing flag: it reconciles the `flux-system` GitRepository first, so
the Kustomization applies **your commit** and not the previously-fetched revision.
5. **T+1:30 — roll the pod.** This step is **mandatory and easy to forget**: a changed Secret does
**not** restart anything. `PLEX_CLAIM` is injected by `secretKeyRef` and read only at container
start, and the Deployment's pod template is byte-identical across this change, so Flux applies the
new Secret and the running pod keeps the old value forever.
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex rollout restart deployment/plex'
```
6. **T+2:00 — confirm the exchange happened**, in the new pod's init log:
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex logs deploy/plex --since=5m | grep -i -e claim -e token'
```
* `Attempting to obtain server token from claim token` **and** `Token obtained successfully`
⇒ **claimed.** Re-run the First-commands `PlexOnlineToken=` check to confirm it persisted, then
create the libraries over `/media/movies`, `/media/tv`, `/media/photos`.
* `Attempting to obtain server token from claim token` with **no** success line ⇒ the token was
expired or invalid. Nothing is broken; go back to step 1 with a new token.
* **Neither line** ⇒ the exchange was skipped, which means `/config` already had a
`PlexOnlineToken` (already claimed) or the env did not reach the container. Check the pod actually
has the variable, by NAME only:
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex get pod -l app.kubernetes.io/name=plex \
-o jsonpath="{.items[0].spec.containers[0].env[*].name}"'
```
## Likely causes, most likely first
When the claim does not take, in order of how often it is the answer here:
1. **The token expired** — you spent more than ~4 minutes, usually in step 3 or waiting on step 4.
Symptom: the "Attempting…" line with no success line. Remedy: a new token, and force the reconcile
rather than waiting for it.
2. **The pod was never restarted** (step 5 skipped). Symptom: no claim log lines at all from a pod
whose `AGE` predates your push. The Secret is correct in git and in the cluster and the running
container still holds the placeholder.
3. **Flux had not applied the commit yet** when you rolled the pod — step 5 run before step 4
finished, so the new pod read the OLD Secret. Check
`kubectl --context k3s-prod -n flux-system get kustomization apps-wave-0 -o jsonpath='{.status.lastAppliedRevision}'`
against your commit, then roll again.
4. **Already claimed** — the exchange is gated on `PlexOnlineToken` being absent from `/config`, so a
server claimed earlier ignores every later token silently. This is the benign case.
5. **`plex.tv` unreachable.** The upstream `curl` has no `--max-time`/`--connect-timeout`, so a stalled
connection can leave the container sitting in cont-init with **nothing listening on 32400** — the
one genuine hang risk in this path. Symptom: pod Running but never Ready, log stops after
"Attempting…". Check egress (`plex` is `egress: internet`) rather than re-rolling repeatedly.
6. **Wrong plex.tv account.** The claim succeeds and binds the server to whoever was signed in at
step 1. Unclaiming is a plex.tv-side operation on that account — see "escalate or stop".
## When to escalate or stop
- **Stop after two failed token attempts** and fix the timing, not the token. The third rushed attempt
is how people start editing live Secrets by hand, which leaves the cluster holding a value that is
in no git commit — precisely the drift `qbittorrent-bootstrap` had to be recovered from.
- **Never `kubectl edit`/`patch` the `plex-claim` Secret in the cluster, and never
`kubectl create secret` it.** Everything durable goes through the SOPS file; a live-only Secret is
reverted (or adopted with the wrong value) on the next reconcile.
- **Never `sops -d` this file into a terminal, a log, or a shared screen**, and never widen the
`PlexOnlineToken=` check into one that prints the value. The token is a plex.tv account credential.
- **If the server got claimed to the wrong account, stop and get the operator.** Reversing it means
removing the server from that account on plex.tv and clearing `PlexOnlineToken` from
`Preferences.xml` on the PVC — a destructive edit of app state on the replicated tier, not a git
change.
- **Do not delete the `plex-config` PVC to "start clean".** It holds the library database, metadata
and watch state (`policy: daily-offcluster`), and it is expensive to rebuild. The claim is a
two-line pref, not a reason to lose the DB.
- After a successful claim, **leave the expired token in the SOPS file**. It is inert (the exchange is
skipped once claimed) and the Secret must keep existing, because the env `secretKeyRef` has no
`optional` — deleting it would put the pod into `CreateContainerConfigError`.
