Paperless-ngx {{ .Chart.AppVersion }} — release {{ .Release.Name }} in namespace {{ .Release.Namespace }}.

{{- if .Values.ingress.enabled }}

ACCESS — INGRESS MODE (ingress.enabled: true, httpRoute.enabled: false)
  https://{{ .Values.ingress.domain }}

  The certificate is requested by cert-manager through the
  "{{ .Values.ingress.clusterIssuer }}" cluster issuer; until it has been issued the browser
  shows a warning. Follow it with

    kubectl -n {{ .Release.Namespace }} get certificate tls-{{ .Release.Name }}-{{ .Chart.Name }}-ingress

  ingress.domain is more than the Ingress host: the chart also hands it to the
  container as PAPERLESS_URL ("https://{{ .Values.ingress.domain }}"), and that is the only
  origin this release declares. While DNS or the certificate are still missing:

    kubectl -n {{ .Release.Namespace }} port-forward svc/{{ .Release.Name }}-{{ .Chart.Name }}-service 8000:80

  Pages then load over http://localhost:8000, but expect the login POST to be
  refused as a CSRF failure — that origin is not PAPERLESS_URL. Forward the
  port to look around, use the domain to log in, or add
  PAPERLESS_CSRF_TRUSTED_ORIGINS through paperless.env for as long as you need
  it. Changing ingress.domain later changes PAPERLESS_URL with it, and the
  pods have to restart before they notice.
{{- else if $httpRoute.enabled }}

ACCESS — GATEWAY MODE (httpRoute.enabled: true, ingress.enabled: false)
{{- range $hostnames }}
  https://{{ . }}
{{- end }}

  This release renders an HTTPRoute ({{ .Release.Name }}-{{ .Chart.Name }}-httproute) and NOTHING
  else of the routing path — no Gateway, no class, no Certificate. Three things
  therefore belong to the cluster and not to this chart, and if any is missing
  the address above does not answer:

    1. The Gateway-API CRDs. Without them this install would have failed.
    2. The Gateway named in httpRoute.parentRefs
{{- range $httpRoute.parentRefs }}
         {{ .name }}{{ if .namespace }} in namespace {{ .namespace }}{{ end }}{{ if .sectionName }}, listener {{ .sectionName }}{{ end }}
{{- end }}
       must exist AND its listener must allow routes from this namespace
       ({{ .Release.Namespace }}) in allowedRoutes. A rejected attachment shows
       up only in the route's status:

         kubectl -n {{ .Release.Namespace }} get httproute {{ .Release.Name }}-{{ .Chart.Name }}-httproute -o yaml

       Read status.parents[].conditions — "Accepted: True" and
       "ResolvedRefs: True" is a working attachment. An empty status means no
       controller has looked at the route at all.
    3. The TLS certificate for the hostname, on the Gateway's listener.
       ingress.clusterIssuer is NOT used in this mode and is not required: the
       chart renders no Certificate, so there is no
       tls-{{ .Release.Name }}-{{ .Chart.Name }}-ingress secret and nothing for cert-manager to do.

  ingress.domain is still required in this mode and is {{ .Values.ingress.domain }}: it is also
  PAPERLESS_URL ("https://{{ .Values.ingress.domain }}"), the only origin this release declares to
  Django, and the route does not replace it. If you set httpRoute.hostnames to
  a name ingress.domain does not carry, the route publishes one host while
  Django trusts another — pages load and every login POST is refused as a CSRF
  failure. Set both together, and remember the pods have to restart before they
  notice a changed domain.

  YOUR WEB-UI UPLOAD LIMIT IS NOT paperless.files.maxUploadFileSize ANY MORE.
  That value ({{ .Values.paperless.files.maxUploadFileSize }}) is NOT ENFORCED in this mode. The chart renders it
  into nginx.ingress.kubernetes.io/proxy-body-size, and the Gateway API has NO
  counterpart — it knows no body size at all, that is implementation-specific
  policy — so this chart deliberately renders no policy object, which would
  bind it to one implementation. Whatever limit the Gateway enforces caps
  uploads through the web UI, and the symptom is the proxy's error rather than a
  message from paperless. Set it at the Gateway or through its
  implementation's own policy object, next to the Gateway and not here.

  The consume directory is unaffected: it passes no proxy and has no size limit
  in any mode, so a document too large for the web UI still gets in that way.

  ingress.annotations is inert in this mode for the same reason — the Gateway
  API has no annotation channel.
{{- else }}

ACCESS — NEITHER INGRESS NOR HTTPROUTE
  ingress.enabled and httpRoute.enabled are both false, so this release is not
  published: no Ingress, no HTTPRoute and no certificate, and
  ingress.clusterIssuer is not needed.

  ingress.domain IS still required and is {{ .Values.ingress.domain }}: the chart hands it to the
  container as PAPERLESS_URL ("https://{{ .Values.ingress.domain }}"), the only origin this
  release declares. Reach the instance inside the cluster with

    kubectl -n {{ .Release.Namespace }} port-forward svc/{{ .Release.Name }}-{{ .Chart.Name }}-service 8000:80

  Pages then load over http://localhost:8000, but expect the login POST to be
  refused as a CSRF failure — that origin is not PAPERLESS_URL. Add
  PAPERLESS_CSRF_TRUSTED_ORIGINS through paperless.env for as long as you need
  it. paperless.files.maxUploadFileSize ({{ .Values.paperless.files.maxUploadFileSize }}) does nothing in this mode:
  it exists only as an ingress-nginx annotation.
{{- end }}
{{ if eq $replicas "0" }}
SCALED TO ZERO
  {{ if .Values.scaleDown }}scaleDown: true{{ else }}paperless.replicas: 0{{ end }} — the StatefulSet runs with replicas: 0, so the URL above
  does not answer until you set it back and upgrade again. PVCs, Secrets,
  Service{{ if .Values.ingress.enabled }} and Ingress stay in place, so neither the documents nor the
  certificate are touched.{{ else if $httpRoute.enabled }} and HTTPRoute stay in place, so the documents are not touched —
  the route then resolves to a Service with no endpoints and the Gateway
  answers its own error.{{ else }} stay in place, so the documents are not touched.{{ end }}
{{- if .Values.smbConnection.enabled }}
{{- if .Values.scaleDown }}
  scaleDown also suspends the SMB consume CronJob, so nothing is moved off the
  share while the release is down.
{{- else }}
  The SMB consume CronJob is NOT suspended by this: only scaleDown sets
  suspend: true. It keeps moving PDFs off the share onto a consume volume that
  nothing is reading — they are gone from the share and not yet in paperless.
{{- end }}
{{- end }}
{{ end }}
WHAT THE 1PASSWORD ITEMS MUST CONTAIN
  The chart creates OnePasswordItem CRs that carry an item path only; the
  operator turns each into a Kubernetes Secret whose keys are the FIELD NAMES
  of the item. Those names are decided here and appear nowhere in 1Password,
  so they are exactly what you would otherwise read out of the templates. A
  missing field does not fail the install — the release goes through and the
  pod then hangs in CreateContainerConfigError naming the key it could not
  find (kubectl -n {{ .Release.Namespace }} describe pod {{ $pod }}).

  secrets.databaseSecretRef → {{ .Values.secrets.databaseSecretRef }}
    Secret {{ .Release.Name }}-{{ .Chart.Name }}-db-secret, fields:
      server     database host — the field is called "server", not "host"
      port       database port
      database   database name
      username   database user
      password   database password
    The engine is pinned to postgresql; there is no value to change it.

  secrets.redisSecretRef → {{ .Values.secrets.redisSecretRef }}
    Secret {{ .Release.Name }}-{{ .Chart.Name }}-redis-secret, fields:
      redis-connection-url   e.g. redis://:PASSWORD@redis:6379
      key-prefix             PAPERLESS_REDIS_PREFIX — set this per release when
                             several releases share one Redis, or two instances
                             will consume each other's task queue
      auth-conf              the COMPLETE line "requirepass PASSWORD", not a
                             bare password. Read by the bundled Valkey only, so
                             it is {{ if $valkeySub }}REQUIRED for this release — see the Valkey
                             section below{{ else }}unused while valkeySubchart.enabled is
                             false, and the item needs it only once you switch
                             the bundled Valkey on{{ end }}.

  secrets.paperlessSecretRef → {{ .Values.secrets.paperlessSecretRef }}
    Secret {{ .Release.Name }}-{{ .Chart.Name }}-secret, fields:
      username               used TWICE: as PAPERLESS_ADMIN_USER and as
                             PAPERLESS_ADMIN_MAIL, so it has to work as both a
                             login name and an address
      password               PAPERLESS_ADMIN_PASSWORD
      paperless-secret-key   Django's SECRET_KEY
    PAPERLESS_ADMIN_* is only acted on while that superuser does not exist yet.
    Editing the password field after the first start changes nothing; reset it
    in the pod instead:

      kubectl -n {{ .Release.Namespace }} exec -it {{ $pod }} -- \
        python3 /usr/src/paperless/src/manage.py changepassword <user>
{{- if .Values.smbConnection.enabled }}

  secrets.smbConnectionSecretRef → {{ .Values.secrets.smbConnectionSecretRef }}
    Secret {{ .Release.Name }}-{{ .Chart.Name }}-smb-secret. This one is not read by any pod: it is
    wired into the PersistentVolume as nodeStageSecretRef, and the
    smb.csi.k8s.io driver reads the fields itself — usually username and
    password, plus domain where the server wants one. The chart names no key
    here, so a wrong field name surfaces as a mount failure on the CronJob's
    pod — a describe on that pod, never a missing variable.
{{- end }}
{{- /*
The warning that used to stand here - "secrets.oidcSecretRef IS SET AND IS READ
BY NOTHING" - is gone with the value itself (13.0.0, Gitea #11). It cannot be
printed any more and would not be reached: the key is out of values.schema.json
too, so a release that still sets it fails BEFORE any template renders, with
"additional properties 'oidcSecretRef' not allowed". The fix is to delete the
key; values.yaml says why it is not coming back.
*/}}

CHANGING A SECRET'S CONTENT RESTARTS NOTHING
  Helm never sees the content of a OnePasswordItem, so it cannot hash it, and
  this chart carries no checksum annotation at all. Pointing a *SecretRef at a
  DIFFERENT item rolls the pods; editing a value INSIDE the same item does not
  — the operator updates the Kubernetes Secret while the running container
  keeps the old value in its environment. After such a rotation:

    kubectl -n {{ .Release.Namespace }} rollout restart statefulset/{{ .Release.Name }}-{{ .Chart.Name }}-sfs

  Rotating paperless-secret-key logs every session out. Rotating the database
  fields points the release at whatever that new endpoint contains, empty or
  not, and the next start migrates it.

POSTGRES IS NOT PART OF THIS CHART{{ if not $valkeySub }}, AND NEITHER IS REDIS{{ end }}
  {{ if $valkeySub }}The database{{ else }}Both{{ end }} ha{{ if $valkeySub }}s{{ else }}ve{{ end }} to exist and be reachable before the first start.{{ if not $valkeySub }} They fail in
  opposite ways, and only one of them is loud:{{ end }}

  - Without the database paperless does not come up at all. All three probes
    ask for "/" on port 8000, so you get no useful error: the pod never turns
    Ready and the startup probe kills it after
    {{ $startup.periodSeconds }}s x {{ $startup.failureThreshold }} = {{ mul $startup.periodSeconds $startup.failureThreshold }}s. Read the container log, not the pod events.
  - Without Redis the web UI comes up and looks healthy. Redis is the Celery
    broker: consumption, OCR, the scheduled tasks and the index updates simply
    never run, and documents dropped into the consume directory stay there.
    A wrong redis-connection-url costs you the whole processing side and
    nothing turns red.{{ if $valkeySub }} This release brings its own Valkey (below), so
    the address is in your hands — which is exactly why the url is the one
    thing to check first.{{ end }}
{{ if $valkeySub }}
THIS RELEASE BRINGS ITS OWN VALKEY — ONE MANDATORY STEP IS IN THE VAULT
  valkeySubchart.enabled is true, so the release contains a Valkey of its own:
  StatefulSet {{ .Release.Name }}-valkey-sfs, Service {{ $valkeySvc }}, its own
  NetworkPolicy, and a PersistentVolumeClaim (persistence is on — this is a
  queue, see below).

  1. THE CONNECTION URL MUST POINT AT IT. This is a step, not a hint: the url
     lives in the vault and the chart cannot write it. In the item
     "{{ .Values.secrets.redisSecretRef }}", field redis-connection-url:

       redis://:PASSWORD@{{ $valkeySvc }}:6379

     Pointing elsewhere is not an error anywhere: paperless talks to that other
     Redis, the Valkey next to it runs along unused, and nothing reports it.

  2. THE PASSWORD IS IN THE ITEM TWICE — once inside redis-connection-url and
     once in the "requirepass PASSWORD" line of auth-conf. Both are the same
     password, and a rotation has to touch BOTH fields. Change only one and
     paperless can no longer authenticate against its own Valkey. After any
     such change, restart both workloads by hand (Helm cannot see inside a
     1Password item, so nothing rolls automatically):

       kubectl -n {{ .Release.Namespace }} rollout restart statefulset/{{ .Release.Name }}-{{ .Chart.Name }}-sfs
       kubectl -n {{ .Release.Namespace }} rollout restart statefulset/{{ .Release.Name }}-valkey-sfs

  3. AUTH-CONF IS A CONFIGURATION LINE, NOT A PASSWORD. The Valkey mounts the
     field as a file and includes it, so the password never reaches a process
     list or an environment variable. An init container refuses to start the
     pod unless a line beginning with "requirepass " is really there — without
     that check a typo would leave a Valkey running with NO password and
     looking perfectly healthy.
{{- if and $valkeyAuth (ne ($valkeyAuth | toString) ($.Values.secrets.redisSecretRef | toString)) }}

  NOTE: valkey.secrets.authSecretRef points at a DIFFERENT item than
  secrets.redisSecretRef:
    valkey.secrets.authSecretRef → {{ $valkeyAuth }}
    secrets.redisSecretRef       → {{ .Values.secrets.redisSecretRef }}
  That is supported and may well be deliberate — the bundled Valkey is then fed
  from its own item. It is only worth knowing that you now keep TWO items in
  step: the password in auth-conf over there and the one inside
  redis-connection-url here have to stay identical.
{{- end }}

  BOTH ITEMS' FIELDS LAND IN BOTH SECRETS. A OnePasswordItem materializes every
  field of the item it names, so with one shared item the Valkey's Secret also
  carries redis-connection-url and key-prefix, and this chart's redis Secret
  also carries auth-conf. Untidy and harmless — nothing mounts a field it does
  not reference. It is mentioned so it does not get "cleaned up".

  IT IS CONFIGURED AS A QUEUE, and that is a decision: persistence on, eviction
  policy "noeviction". PAPERLESS_REDIS is the Celery broker, so its contents are
  work that must not vanish — "allkeys-lru" would evict across the whole
  keyspace and a backlog of waiting tasks is exactly what LRU reads as cold.
  The price: the same instance also serves the Django cache, so when it fills,
  writes are REFUSED rather than old keys dropped — new tasks included. The
  answer is to give it more memory (valkey.valkey.resources.requests.memory),
  never to switch the policy. values.yaml argues this in full.

  SCALEDOWN DOES NOT REACH IT. scaleDown: true scales paperless to zero and
  leaves the Valkey running, which is the right way round for a queue: the
  backlog stays where it is.
{{- end }}

THE FIRST START MIGRATES, AND THE STARTUP PROBE IS THE CLOCK
  Every start runs the database migrations before the server answers, and the
  first start after an upgrade to 3.x also rebuilds the search index from
  scratch (Whoosh → Tantivy). The startup probe grants
  {{ $startup.failureThreshold }} x {{ $startup.periodSeconds }}s = {{ mul $startup.periodSeconds $startup.failureThreshold }}s before the kubelet restarts the container — and a
  restart lands in the middle of a migration. On a large archive, raise
  paperless.startupProbe.failureThreshold BEFORE the app-version jump, not
  after the crash loop has started.

  Migrations are one-way. "helm rollback" puts the old image back on a database
  the new one has already rewritten. Back up before bumping the app version,
  and back up both halves — the metadata lives in Postgres, the documents on
  the PVC.

HOW DOCUMENTS GET IN
  Everything in /usr/src/paperless/consume is picked up by the consumer. That
  directory is its own volume, {{ .Release.Name }}-{{ .Chart.Name }}-consume-volume-claim, and its size is
  NOT paperless.files.storage: the claim is hardcoded to 1Gi (ReadWriteMany)
  in the template, and both PVCs are hardcoded to storage class "longhorn".
  paperless.files.storage ({{ .Values.paperless.files.storage }}) sizes only the main volume, which holds
  data/, media/ and export/ as subPaths.

{{- if .Values.ingress.enabled }}
  Uploads through the web UI take the second route and pass the Ingress, where
  the chart sets a body-size cap of {{ .Values.paperless.files.maxUploadFileSize }} (paperless.files.maxUploadFileSize,
  rendered into both the nginx.ingress and nginx.org annotations). A larger
  file is rejected by the ingress controller with a 413 before paperless ever
  sees it — the consume directory has no such limit.
{{- else if $httpRoute.enabled }}
  Uploads through the web UI take the second route, and in GATEWAY MODE
  paperless.files.maxUploadFileSize ({{ .Values.paperless.files.maxUploadFileSize }}) is NOT ENFORCED: it exists only as
  an ingress-nginx annotation and the Gateway API has no body-size field, so
  the cap is whatever the Gateway enforces. The consume directory has no limit
  in either mode.
{{- else }}
  Uploads through the web UI take the second route, but nothing publishes this
  release and paperless.files.maxUploadFileSize ({{ .Values.paperless.files.maxUploadFileSize }}) is rendered nowhere:
  it exists only as an ingress-nginx annotation. The consume directory has no
  limit either way.
{{- end }}
{{- if .Values.smbConnection.enabled }}

  SMB CONSUME IS ON — AND IT MOVES ONLY TOP-LEVEL PDFs
    CronJob {{ .Release.Name }}-{{ .Chart.Name }}-consume-cronjob, schedule "{{ .Values.smbConnection.cronJob }}", mounts
    //{{ .Values.smbConnection.server }} and runs, once per firing:

      find /mnt/smb -maxdepth 1 -name "*.pdf"  →  mv into the consume volume

    Read that literally. Anything in a SUBDIRECTORY of the share is never
    touched, and anything that is not *.pdf — an image, an .eml, a .PDF in
    capitals — stays on the share forever with nothing reporting it. It is a
    move, not a copy: once the job has run, the share no longer holds the file
    and the only copy is on the consume volume.

    The schedule is quoted on the way into the manifest since 13.0.0, so any
    cron notation works — one starting with "*" or an "@daily" macro included.
    Before that such a schedule aborted the render with a YAML parse error
    pointing at the template, and the advice here was to avoid it; if you are
    carrying a workaround schedule from that era ("5,20,35,50 * * * *" instead
    of every 15 minutes), you can write what you meant now.
{{- if $cronPinned }}

    PLACEMENT: the mover runs on the NODE OF THE STATEFULSET POD, via a
    required podAffinity on its label (Gitea #101). Without that it lands
    anywhere, and because it mounts the consume volume — RWX, from Longhorn —
    the kubelet of the StatefulSet's node then retries the mount every two
    minutes with "no Pending workload pods for volume ... to be mounted". It
    was measured at 291 such events in 10 hours.

    THE PRICE, and it is the one thing to know before scaling down: with no
    StatefulSet pod the mover CANNOT BE SCHEDULED. scaleDown: true suspends
    this CronJob outright, so that case is covered — but paperless.replicas: 0
    with SMB still on is not, and there the job fails once per schedule after
    activeDeadlineSeconds ({{ $cronDeadline }}s) with reason DeadlineExceeded. That is
    deliberate: a bounded, visible failure rather than a Pending pod per
    schedule that nobody sees. Switch smbConnection.cron.pinToServerNode to
    false to go back to unpinned placement — and to the mount errors.

    What the pinning does NOT fix: the consume volume stays RWX with a
    share-manager behind it. Co-locating the two consumers removes the
    cross-node mount, not the second consumer.
{{- else }}

    PLACEMENT IS OFF (smbConnection.cron.pinToServerNode: false). The mover
    will be scheduled wherever there is room, and when that is not the node of
    the StatefulSet pod, Longhorn refuses to mount the shared RWX consume
    volume there: the kubelet of the StatefulSet's node retries every two
    minutes with "no Pending workload pods for volume ... to be mounted"
    (Gitea #101, measured at 291 events in 10 hours). The errors stop when the
    StatefulSet pod is deleted and comes back Pending, and return with the next
    firing of this job.
{{- end }}

    The job has NO probes (the documented exception to the chart conventions),
    and it cannot fail usefully either: with nothing to move it exits 0, which
    is indistinguishable from a successful run. Judge it by what arrives, not
    by the Job's status:

      kubectl -n {{ .Release.Namespace }} get jobs --sort-by=.metadata.creationTimestamp
      kubectl -n {{ .Release.Namespace }} logs job/<name-of-the-last-one>

    The share is reached through the smb.csi.k8s.io driver, which this chart
    does not install. The PersistentVolume {{ .Release.Name }}-{{ .Chart.Name }}-smb-pv is CLUSTER-scoped
    with reclaim policy Retain and its volumeHandle is derived from
    smbConnection.server alone — two releases pointing at the same server
    collide on that handle, and a Retained PV outlives helm uninstall and
    blocks the next install of the same name until it is deleted by hand.
{{- else }}

  smbConnection.enabled is false, so nothing fills that directory on its own —
  the web UI is the only way in. To hand a file over directly:

    kubectl -n {{ .Release.Namespace }} cp <file.pdf> {{ $pod }}:/usr/src/paperless/consume/
{{- end }}

WHAT A GREEN POD DOES NOT PROVE
  One container runs the web server and the Celery worker and scheduler side
  by side under s6-overlay, and all three probes only ask the web server for
  "/". A worker that died, a consumer that is not watching and a broken Redis
  connection all leave the pod Ready and the rollout green. The honest check is
  a document going in and coming out the other side, plus:

    kubectl -n {{ .Release.Namespace }} logs {{ $pod }} | grep -i -e error -e celery

  A read-only root filesystem is part of that picture too: only /tmp and /run
  are writable. Anything the app would install at runtime — an extra tesseract
  language pack, for instance — cannot be written, no matter which variable
  asks for it.

OCR AND BARCODES AS THIS RELEASE HAS THEM
  language "{{ .Values.paperless.ocr.languages }}" · mode {{ .Values.paperless.ocr.mode }} · archive {{ .Values.paperless.ocr.archiveFileGeneration }} · output {{ .Values.paperless.ocr.output_type }} · rotate {{ .Values.paperless.ocr.rotate_pages }}

  paperless.ocr.languages sets PAPERLESS_OCR_LANGUAGE — which language to use.
  The chart does not set the plural PAPERLESS_OCR_LANGUAGES that makes the
  image fetch further packages at start, and with the read-only rootfs above it
  could not work anyway: a language the image does not already carry needs a
  different image, not a different value.

  In 3.x the OCR mode values "skip" and "skip_noarchive" no longer exist —
  "auto" replaces them, and archive generation is a separate setting.

  barcodes: {{ if $barcodes.enabled }}enabled, separator "{{ $barcodes.barcodeString }}", split pages {{ if $barcodes.retainBarcodePage }}retained{{ else }}discarded{{ end }}, ASN {{ if $barcodes.asn.enabled }}on{{ else }}off{{ end }}{{ else }}disabled{{ end }}
  A childless "barcodes:" key in a values file is YAML null and means "chart
  defaults apply" here (issue #61) — it does NOT switch barcodes off. Deleting
  the sub-keys gets you the defaults back; only barcodes.enabled: false
  disables it.
{{- if .Values.paperless.files.deleteDuplicates }}

  paperless.files.deleteDuplicates is on: a document that matches one already
  in the archive is DELETED on consume instead of being kept. That is the 2.x
  behaviour, which 3.0 dropped as a default.
{{- end }}
{{- if .Values.paperless.files.tikaGotenberg.enabled }}

TIKA AND GOTENBERG — THE ENDPOINTS CARRY NO SCHEME
  tika        http://{{ .Values.paperless.files.tikaGotenberg.tikaEndpoint }}
  gotenberg   http://{{ .Values.paperless.files.tikaGotenberg.gotenbergEndpoint }}

  The chart prefixes "http://" itself, so these two values are bare host:port.
  A value written with a scheme renders as http://http://… and every Office
  document fails to convert while everything else keeps working. Neither
  service is part of this chart or checked at startup.
{{- end }}
{{- if .Values.oidc.enabled }}

OIDC IS ON, AND IT IS PKCE-ONLY
  Register this redirect URI at the provider:

    https://{{ .Values.ingress.domain }}/accounts/oidc/{{ .Values.oidc.provider.id }}/login/callback/

  The chart enables PKCE and configures NO client secret — the client has to be
  registered as one that can complete the flow without one. Nothing about OIDC
  is exercised before someone actually signs in, so a wrong discovery URL,
  client id or redirect URI surfaces as a failed login on a perfectly healthy
  pod.
{{- if not .Values.oidc.provider.tokenAuthMethod }}

  oidc.provider.tokenAuthMethod is unset. Since the allauth update in 3.0 some
  providers need it spelled out, and the symptom when they do is a login that
  dies at the callback with invalid_client. The only value this chart accepts is
  "none" — it states the public client explicitly. A method that authenticates
  WITH a client secret cannot work here and is rejected by the schema (13.0.0,
  Gitea #11): this release configures no client secret and cannot, because
  paperless reads the whole OIDC configuration out of one json environment
  variable with no _FILE variant.

  superuser still has a usable password and check that Django's admin login at
  /admin/ still lets that account in; it is the only way back when the provider
  is unreachable.

paperless.scripts IS SET AND DOES NOTHING
  {{ len $pre }} pre- and {{ len $post }} post-consumption script(s) are configured. The
  ConfigMap that would carry them is disabled in this chart ({{ "{{- if false }}" }} at the
  top of the template), no volume mounts it, and neither
  PAPERLESS_PRE_CONSUME_SCRIPT nor PAPERLESS_POST_CONSUME_SCRIPT is set on the
  container. These values render no object and change no behaviour.

{{- if .Values.paperless.env }}

paperless.env ADDS {{ len .Values.paperless.env }} VARIABLE(S) — AND AN OVERRIDE ONLY BITES AT INSTALL
  {{ range $i, $e := .Values.paperless.env }}{{ if $i }}, {{ end }}{{ $e.name }}{{ end }}

  These are appended AFTER the variables the chart sets itself, so at INSTALL an
  entry repeating one of those names wins. On an upgrade of an EXISTING release
  the same entry is lost: Kubernetes merges env by name, the pair collapses to
  the chart's own value, and helm upgrade still reports success. Read the value
  back off the StatefulSet, never off the upgrade's exit code:

    kubectl -n {{ .Release.Namespace }} get statefulset {{ .Release.Name }}-{{ .Chart.Name }}-sfs \
      -o jsonpath='{.spec.template.spec.containers[0].env}'
{{- end }}
{{- if gt (int $replicas) 1 }}

paperless.replicas IS {{ $replicas }} — EXPECT ONE POD TO WORK AND THE REST TO WAIT
  The main volume is a plain ReadWriteOnce PVC shared by the whole
  StatefulSet, not a volumeClaimTemplate, so the second pod stays Pending on
  "Multi-Attach error for volume" unless the storage class is genuinely RWX —
  and where it does start, two consumers watch the same directory and two
  schedulers run the same periodic tasks.
{{- end }}

BACKUP IS TWO THINGS AT THE SAME TIME
  Postgres holds the metadata, the tags and one row per document; the PVC
  {{ .Release.Name }}-{{ .Chart.Name }}-volume-claim holds the files under data/, media/ and export/.
  Restoring one without the other gives you an archive full of references to
  documents that are not there. Snapshot them together.

  Both PVCs are rendered by this chart, so helm uninstall deletes them and the
  documents with them unless the storage class reclaim policy says otherwise.
  The external database survives that — which makes an accidental uninstall
  look recoverable while the files are already gone.
{{- if .Values.paperless.env }}

  paperless.env adds {{ len .Values.paperless.env }} variable(s), rendered after the ones the chart
  sets itself, so they win on a name the chart also sets.

{{- if .Values.networkPolicy.enabled }}

NETWORKPOLICY IS ACTIVE — WHAT IT CAPS, AND WHAT IT DOES NOT
  {{ .Release.Name }}-{{ .Chart.Name }}-networkpolicy selects this workload's pods.
  Inbound: TCP 8000 only. Outbound: DNS, TCP 5432 (Postgres), 6379
  (Redis/Valkey), 443{{ if .Values.paperless.files.tikaGotenberg.enabled }}, 9998 and 3000 (the Tika and Gotenberg POD ports) plus 80{{ end }}{{ with .Values.networkPolicy.egress }}{{ if .mailImport }}, 993 (IMAPS, mail import){{ end }}{{ with .extraPorts }}, plus TCP
  {{ join ", " . }}{{ end }}{{ end }}.
{{- if .Values.paperless.files.tikaGotenberg.enabled }}

  THE TIKA/GOTENBERG RULE NAMES POD PORTS, AND THAT IS THE FIX FROM GITEA #136.
  It named the Services' 80 alone until chart 14.1.0, which cut Paperless off
  from both services: kube-proxy does a ClusterIP Service's destination NAT
  BEFORE the egress policy is evaluated at the pod's interface, so the policy
  sees podIP:targetPort. The symptom was a TIMEOUT and not "connection refused",
  and no error mentioned a NetworkPolicy. If this release reaches a Tika or
  Gotenberg that listens on some other port, that port goes into
  networkPolicy.egress.extraPorts.
{{- end }}
{{- if (.Values.networkPolicy.egress).mailImport }}

  MAIL IMPORT IS PERMITTED on 993 (IMAPS), because
  networkPolicy.egress.mailImport is on. Plain IMAP (143) and POP3 are NOT
  covered — add them to networkPolicy.egress.extraPorts if an account uses them.
{{- else }}

  MAIL FETCHING IS NOT PERMITTED. Paperless' mail accounts are rows in its
  database, configured in the web UI, so this chart cannot see them. A release
  that fetches mail needs networkPolicy.egress.mailImport: true for IMAPS (993),
  or 143/POP3 in networkPolicy.egress.extraPorts — otherwise a mail rule
  silently stops importing, with a healthy pod behind it.
{{- end }}

  AND TWO PODS OF THIS RELEASE ARE NOT COVERED BY THIS OBJECT:
    - the valkey subchart's pod, which carries its own labels. It needs no
      cover from here: the valkey chart ships its own NetworkPolicy, and a
      tighter one.
    - the consume CronJob's pods, whose pod template carries NO labels at all,
      so no podSelector can match them. They move files between mounted
      volumes and reach the SMB share through a CSI volume the NODE mounts, so
      the pod opens no connection of its own — but the gap is real and is named
      here rather than left to be discovered.

  Three limits belong in the same breath, because none of them is visible in
  the object itself:

  - EGRESS IS BY PORT, NEVER BY DESTINATION. A NetworkPolicy matches CIDRs and
    selectors and cannot express a hostname, so every egress rule permits its
    port to ANY address. That is a limit of the object, not a shortcut — this
    cluster's CNI (Canal: Flannel plus Calico) has no FQDN rule either. An
    outbound port the chart does not know about is BLOCKED: add it to
    networkPolicy.egress.extraPorts, and expect to find out through an
    application-level connection error rather than through this object.
{{- if .Values.networkPolicy.probeSources }}
  - THE PROBE PATH IS RESTRICTED in this release, because
    networkPolicy.probeSources is set to
      {{ join ", " .Values.networkPolicy.probeSources }}
    Probes come from the IP of the WORKER NODE running the pod. If none of those
    CIDRs covers the node this pod lands on, the kubelet's probes are dropped
    and THE POD NEVER BECOMES READY — the rollout then times out and the symptom
    looks like a broken application. Compare

      kubectl -n {{ .Release.Namespace }} describe pod -l app={{ .Release.Name }}-{{ .Chart.Name }}-sfs

    against `kubectl get node -o wide`.
{{- else }}
  - THE PROBED PORT IS OPEN INSIDE THE CLUSTER. networkPolicy.probeSources is
    empty, so that rule carries no source selector at all and any pod the CNI
    routes to can reach it. Not from the internet — but this is NOT pod-level
    isolation. Narrowing it means listing the worker node IPs in
    networkPolicy.probeSources, because the kubelet probes from the node's own
    address and the chart cannot know it; a wrong guess there leaves the pod
    permanently un-Ready.
{{- end }}
  - IT IS ONLY A BOUNDARY WHERE THE CNI ENFORCES POLICIES. Where it does not,
    this object is accepted and filters nothing, so everything reads as
    configured while nothing is filtered. `kubectl -n {{ .Release.Namespace }} get networkpolicy`
    shows the object exists; only a connection attempt from an unrelated
    namespace shows that it bites.

  Switch it off with networkPolicy.enabled: false.
