jklein 6c73ef874b Eight charts: seccompProfile RuntimeDefault and qualified images
Sets seccompProfile.type: RuntimeDefault in the pod security context of
minecraft-router, outline, urlaubsverwaltung, zipline, voucher-vault,
satisfactory, patchmon and calibre-web-automated, so the container
runtime's default syscall filter applies to every container in the pod.

The value lives in the pod context rather than the container context
because it covers init containers and any container added later without
being repeated; a container that needs a different filter can still
override it under securityContext.container, which wins over the pod
value.

Five of the eight also get the docker.io/ prefix on their previously
unqualified image references, so the pull no longer depends on the
runtime's default-registry setting: itzg/mc-router,
outlinewiki/outline, urlaubsverwaltung/urlaubsverwaltung,
l4rm4nd/vouchervault (twice, app and init container) and
guacamole/guacd:1.6.0. zipline, satisfactory and calibre-web-automated
were already qualified with ghcr.io.

Verified in a throwaway k3d cluster against real application work, not
just a Running pod, and with Seccomp: 2 (filter mode) read from
/proc/<pid>/status inside each container:

- minecraft-router: a Minecraft handshake for a mapped domain travels
  through the router to a backend and the backend's status payload comes
  back to the client.
- outline: all migrations apply (45 tables), OIDC discovery succeeds and
  the server-rendered page answers 200 with <title>Outline</title>.
- urlaubsverwaltung: Liquibase applies 79 changesets (35 tables), the app
  seeds its settings and vacation types, /login answers 200.
- zipline: 27 migrations applied, then a full round trip - first user
  created, login, token, upload, and the file downloaded back byte-exact
  from the PVC.
- voucher-vault: the init container's collectstatic output is served
  (200, 22 KB), Django has its 22 tables and uWSGI answers 200 with
  <title>VoucherVault</title>.
- satisfactory: application behavior is NOT proven - the image is
  multiple GB and pulls 10 GB+ of game files on first start, which is why
  the chart sits in ci/excluded-charts.txt. What is proven is that the
  rendered pod securityContext is accepted server-side and yields
  Seccomp: 2 with uid/gid 1000 on a substitute image.
- patchmon: both containers run under the pod profile and both report
  Seccomp: 2. The server applies 47 migrations (44 tables), connects to
  Postgres and Redis and serves its dashboard; guacd answers a real
  Guacamole "select rdp" instruction with its full args list, over the
  same 127.0.0.1:4822 path the chart wires up.
- calibre-web-automated: the readOnlyRootFilesystem: false deviation is
  unaffected - id abc is still uid 1000 (not the 911 the image falls back
  to in read-only mode), /config and the Calibre metadata.db are owned by
  1000, and both the root s6 init and the uid-1000 application report
  Seccomp: 2. calibredb 9.1 runs and adds a book. Its IPC worker prints a
  traceback while doing so, but an unconfined control pod on the same
  image prints the same class of traceback, so it is not the filter.

trivy config now reports "0 to act on" for all eight; the untouched
samba still shows KSV-0104 and KSV-0030, which confirms these charts are
what closed the findings.

No values.schema.json needed changing: in all eight schemas
securityContext.pod is type ["object", "null"] with no property
restrictions, so the new key validates as it stands. The #99 null paths
still hold - nulling securityContext or securityContext.pod falls back to
the defaults including the new one.

Renovate resolves the prefixed guacd reference: a local dry-run lookup
(renovate 44.40.1, --platform=local --dry-run=lookup) reports depName
docker.io/guacamole/guacd against registryUrl https://index.docker.io
with lookupName guacamole/guacd, currentVersion 1.6.0 and its real
release timestamp, with no warnings. The other four prefixed references
live in templates, which Renovate never reads - they are tracked by the
customManagers via appVersion in Chart.yaml with a depName hardcoded in
renovate.json5, so they are unaffected.

Major bump for all eight: runtime behavior changes.

jklein 40289a2e67 zipline: strict values.schema.json, ingress gate and null-safe hardening
Three changes, all about values that do not do what they promise:

1. values.schema.json (#68): additionalProperties: false on every
   chart-owned object level, so a key the chart does not read is rejected
   at render time instead of being silently ignored.

2. Ingress gate (#93): the Ingress template is wrapped in
   {{- if .Values.ingress.enabled }} and the key is added to values.yaml
   with default true, so behaviour is unchanged.

   As in rallly, ingress.domain is not a pure Ingress value: the
   StatefulSet also feeds it to CORE_DEFAULT_DOMAIN, the app's default
   domain for generated share links, and did so without required(). The
   guarantee only came from the ungated Ingress template, so the gate
   would have handed out unusable links silently. That read is now
   required() as well; only clusterIssuer becomes unnecessary.

3. Null-safety for hardening, probes and resources (#99): an erased block
   fell back to "securityContext: null" (unhardened), a vanished probe or
   a container without resource accounting. The rebuilt liveness probe
   keeps "/" rather than /api/healthcheck, so a database outage still does
   not restart the pod.

config stays deliberately not null-safe: storage and storageClass are
required(), which puts an erased block in the loud class #99 excludes.

Apart from an added comment, the rendered manifest is unchanged.

jklein 48cb5c01de Zipline chart: ingress standard, secret ref structure (conventions batch 3)
Repo-standard flexible ingress (required clusterIssuer instead of the
hardcoded letsencrypt-issuer, domain moved from config.domain to
ingress.domain, className value, annotations merge, standard TLS secret
name), secrets.<name>SecretRef structure, core secret renamed to the
standard -secret name, additive tpl-rendered env block, documented PVC
naming exception. Major bump 4.1.2+up4.7.0 -> 5.0.0+up4.7.0.

jklein 6779e49355 Add per-workload replicas values and a chart-global scaleDown flag
Every Deployment/StatefulSet now takes its replica count from a replicas
value (default 1, explicit 0 allowed) via a new per-chart <chart>.replicas
helper; the helper uses a kindIs "invalid" nil check so an explicit 0 is
not swallowed by Helm's default function. A chart-global scaleDown flag
(default false) takes precedence: it renders every workload with
replicas: 0 and suspends the paperless-ngx consume CronJob, stopping the
app without uninstalling it (PVCs, Secrets, Services and Ingress remain).

Defaults leave the rendered manifests byte-identical to main, so all
published charts get a minor version bump; the template-chart carries the
reference helper implementation and stays unversioned.

Fixes #25

jklein 91a2fbcb05 Compute memory/ephemeral-storage limits from requests, drop default CPU limits
Every chart now renders its container resources through a duplicated
_helpers.tpl helper (reference implementation in template-chart): requests
ship as chart defaults, missing memory and ephemeral-storage limits are
computed as resources.limitFactor x the request (default 3, satisfactory
keeps 2 to preserve its previously published 8Gi limit), an explicitly set
limit always wins, and a CPU limit is only rendered when set explicitly.
Fixed limit defaults are removed from all values.yaml files; teamspeak-server
gains a values-driven resources block instead of hardcoded template values.
Major version bump for all published charts.

jklein b5eba4cbf1 Harden pod and container security contexts across all workloads
Add securityContext hardening (runAsNonRoot, readOnlyRootFilesystem,
capabilities drop ALL, allowPrivilegeEscalation false) to the 10 workloads
that lacked it: apache-tika, cyberchef, gotenberg, homeassistant,
matrix-delegation-nginx, paperless-server, paperless-consume cronjob
(plus automountServiceAccountToken false), patchmon-frontend,
urlaubsverwaltung and zipline. All contexts are configurable via
securityContext.pod / securityContext.container in values.yaml; writable
paths are provided as emptyDirs. Image-forced deviations (Home Assistant
root start for s6-overlay + NET_RAW for discovery, paperless root init
container for /run ownership) are documented in the charts' values.yaml.
Major version bump for every changed published chart.

jklein 7f1ef4055f Refine probes based on k3d cluster verification
Every chart was installed twice in a throwaway k3d cluster (origin/main
vs this branch) with real Postgres/Redis/dex instances and observed for
readiness ordering, stability and dependency-outage behavior. Findings:

- voucher-vault: Django only accepts Hosts 127.0.0.1 and the configured
  DOMAIN; the default probe Host (pod IP) always got 400. Probes now
  send 'Host: 127.0.0.1'.
- zipline: /api/healthcheck includes the database, so liveness now uses
  '/' (readiness/startup keep /api/healthcheck). Verified live: on a
  Postgres outage the pod turns NotReady within 30s and is never
  restarted by the kubelet.
- outline: '/' also returns 500 when the database is down, so there is
  no dependency-free endpoint; all three probes use /_health.

jklein 78d78973c5 Ensure liveness, readiness and startup probes on all workloads
Every container in every Deployment/StatefulSet now defines all three
probes. The paperless-ngx consume CronJob intentionally has none (batch
workload).

- Add probes: apache-tika, calibre-web-automated, cyberchef, gotenberg,
  homeassistant, patchmon-backend, samba (tcp/445), teamspeak-server
  (tcp/30033), zipline (/api/healthcheck)
- Fix voucher-vault null probe values with real defaults
- Fix startup-probe semantics in template-chart and rallly (no
  initialDelaySeconds, generous failureThreshold)
- Switch outline probes to its /_health endpoint
- Add readiness/startup probes to satisfactory
- Add startup probes to matrix-synapse, matrix-delegation-nginx,
  paperless-server, patchmon-frontend, urlaubsverwaltung
- Major version bump for all published charts
