freesailarr — release {{ .Release.Name }} in namespace {{ .Release.Namespace }}.
Nine containers in ONE pod, sharing gluetun's network namespace.

NOTHING IS READY UNTIL THE TUNNEL IS UP
  gluetun's readiness probe is its health server, which answers 200 only while
  the Wireguard tunnel is actually working. So "pod not Ready" almost always
  means "no tunnel", not "app broken". The startup budget is {{ $budget }}s before
  Kubernetes starts killing the container:

    kubectl -n {{ .Release.Namespace }} logs {{ $name }}-sfs-0 -c gluetun -f

  While gluetun is down its firewall keeps blocking every app container's
  egress. That is the kill switch doing its job — the apps stay up and simply
  reach nothing.

THE 1PASSWORD ITEM AND THE TWO FIELDS IT MUST CONTAIN
  secrets.gluetunSecretRef -> {{ .Values.secrets.gluetunSecretRef | default "(not set)" }}
    wireguard-private-key
    wireguard-addresses

  A missing field does not fail the install: gluetun starts with the variable
  empty and never completes a handshake.

    kubectl -n {{ .Release.Namespace }} get onepassworditem {{ $name }}-gluetun-secret
{{- if not .Values.gluetun.vpn.firewallOutboundSubnets }}

SET gluetun.vpn.firewallOutboundSubnets — IT IS EMPTY RIGHT NOW
  Without it the gluetun firewall blocks cluster-internal egress as well:
  lookups against cluster DNS and seerr reaching an in-cluster Jellyfin both
  fail, in a way that looks like an application bug. Set it to the cluster pod
  and service CIDRs, e.g. "10.42.0.0/16,10.43.0.0/16" on k3s.
{{- end }}

ACCESS
{{- if and .Values.ingress.enabled $ingressApps }}
{{- range $ingressApps }}
{{- $cfg := (index $.Values .name).ingress }}
  {{ .name }}: https://{{ $cfg.host }}
{{- end }}

  Each app has its OWN Ingress and its own TLS secret; while cert-manager is
  still issuing, the browser warns:

    kubectl -n {{ .Release.Namespace }} get certificate
{{- else }}
  No Ingress is rendered{{ if not .Values.ingress.enabled }} (ingress.enabled is false){{ end }}. Reach an app through its own service:
{{- range $portApps }}

    kubectl -n {{ $.Release.Namespace }} port-forward svc/{{ $name }}-{{ .name }}-service {{ .port }}:{{ .port }}
{{- end }}
{{- end }}
{{- if .Values.qbittorrent.enabled }}

  qBittorrent's WebUI rejects a Host header whose port differs from its own
  ({{ "8080" }}) with a plain 401. A port-forward on a different local port therefore
  looks like a login failure — forward 8080:8080, or go through the ingress.
{{- end }}

EVERY SERVICE POINTS AT THE SAME POD IP
  One ClusterIP service per app{{ if .Values.recyclarr.enabled }} (recyclarr has none — no port in daemon mode){{ end }}, but all
  containers share gluetun's network namespace, so the services differ only in
  their port. They give you stable per-app DNS names, NOT network separation
  between the apps.

TOGGLING AN APP OFF AND ON LATER NEEDS ONE MANUAL STEP
  The config volumes come from volumeClaimTemplates, and those are immutable.
  Changing any <app>.enabled after the first install makes the upgrade fail
  until the StatefulSet is recreated — the data survives:

    kubectl -n {{ .Release.Namespace }} delete statefulset {{ $name }}-sfs --cascade=orphan

THE MEDIA CLAIMS ARE YOURS, THE CONFIG VOLUMES ARE THE CHART'S
  media.<category>.existingClaim is mounted, never created, and is meant to be
  shared with your Jellyfin. One claim can serve all three categories via
  media.<category>.subPath.

  Measured, so you do not plan around something that does not happen: Radarr
  and Sonarr do NOT hardlink between the categories, not even on one claim.
  Kubernetes makes every volumeMount its own bind mount and link() across two
  mount points fails with EXDEV regardless of subPath, so an import copies.

  The containers write as {{ .Values.puid }}:{{ .Values.pgid }}. If the claims already hold data
  owned by someone else, fix the ownership before the first start — the pod
  will not do it for you (fsGroupChangePolicy is OnRootMismatch, deliberately,
  so a large library is not recursively re-chowned on every start).
{{- if eq $replicas "0" }}

SCALED TO ZERO
  {{ if .Values.scaleDown }}scaleDown: true{{ else }}replicas: 0{{ end }} — the StatefulSet runs with replicas: 0. PVCs, secrets,
  services{{ if .Values.ingress.enabled }} and ingresses{{ end }} stay in place; set it back and upgrade to bring the
  stack up again.
{{- else if ne $replicas "1" }}

MORE THAN ONE REPLICA IS NOT MEANINGFUL
  replicas is {{ $replicas }}. Each replica would run its own isolated stack on its own
  config volumes, all of them fighting over the same media claims and the same
  VPN credentials.
