jklein f761767630 urlaubsverwaltung: correct the env-collision claim, answer the recovery question
The chart told operators that adding a duplicate env name to an installed
release makes the next upgrade fail in the API server, quoting "The order in
patch list ... doesn't match $setElementOrder list". Measured against helm
3.19.0 and Kubernetes 1.35, it does not fail: the upgrade succeeds, helm prints
"Release has been upgraded", and Kubernetes merges the env list by name, so the
duplicate pair collapses to the chart's own entry and the operator's override is
discarded without a word. At install time the same values behave differently -
both entries reach the pod, the later one wins, and the API server says so with
"hides previous definition of ..., which may be dropped when using apply".

The advice that followed from the old claim survives - such a switch only takes
at install time - but the stated reason was wrong in the dangerous direction. A
reader who expects a loud failure treats a green upgrade as proof the override
took effect, and green is exactly what a silently dropped override looks like.
The text now names the real failure mode and tells the reader to read the value
back off the Deployment. README carries the same correction, because every chart
in this repo offers the same additive env block.

Also records what the earlier measurement left open. With the database scaled
back up the pod returns to Ready on its own after about five seconds, restart
count still 0, so leaving the liveness group untouched costs no manual recovery.
And the limit of that signal belongs next to it: the db indicator validates a
connection, not the schema, so a database that came back empty still put the pod
back to Ready with /actuator/health at 200.

jklein f8acdfdfe1 urlaubsverwaltung: readiness must see the database, health must not lie (9.0.0+up6.7.0)
MANAGEMENT_ENDPOINT_HEALTH_GROUP_READINESS_INCLUDE=readinessState,db puts the datasource into Spring Boot's readiness group, which shipped with readinessState alone: a total database outage left the pod 1/1 Ready while every request failed. Naming the members replaces the default, so readinessState is repeated. The liveness group stays untouched on purpose, because an outage has to keep traffic away rather than add a crash loop to it.

MANAGEMENT_HEALTH_MAIL_ENABLED=false removes the mail indicator, which pinned the aggregate /actuator/health at 503 for the whole life of a healthy release, because the chart's mail wiring points at localhost:1025 where nothing listens. values.yaml and NOTES.txt document what that costs and when it has to be switched back on.

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 22fdb58396 Strict clusterIssuer also for cyberchef and urlaubsverwaltung
Per the maintainer decision (option a: ingress.clusterIssuer strictly
required in ALL charts) the two remaining defaults are removed as well:

- cyberchef: drop the letsencrypt default; bump raised from minor to
  major (6.0.0+up11.4.0) as this is a breaking values change.
- urlaubsverwaltung: drop the letsencrypt-issuer default; major bump
  to 6.0.0+up6.7.0.
- CI test-values for both charts now set clusterIssuer explicitly.

A repo-wide grep confirms no chart carries a clusterIssuer default
anymore.

jklein 9d22b3b921 urlaubsverwaltung chart: naming scheme, configurable probes, flexible ingress
- Rename all resources from <chart>-<release>-uv-<kind> to the repo
  standard <release>-<chart>-<kind> (deployment, service, ingress, both
  OnePasswordItem secrets); drop the uv infix. No PVCs in this chart, so
  no storage migration is needed.
- TLS secret renamed to the standard tls-<release>-<chart>-ingress
  (was tls-<chart>-<release>-ingress).
- Probes lifted into values (urlaubsverwaltung.livenessProbe/
  readinessProbe/startupProbe); defaults are exactly the previously
  hardcoded, issue-#9-calibrated settings.
- Repo-standard flexible ingress: ingress.className (default nginx),
  ingress.annotations merged with the cert-manager annotation,
  ingress.enabled flag; domain/clusterIssuer stay required.
- Additive urlaubsverwaltung.env block rendered through tpl with
  value/secretKeyRef/configMapKeyRef forms.
- CI fixtures updated to the new secret names.

Major bump 4.1.2+up6.7.0 -> 5.0.0+up6.7.0 (resource renames).

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.

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.
