bentopdf, apache-tika, gotenberg, rss-bridge, searxng, ytdlp-web-player. One
major each, networkPolicy.enabled defaults to true.
Three of them differ from the simple case in ways worth naming:
GOTENBERG gets DNS-only egress as a deliberate, documented trade. It drives a
headless Chromium, and 3000 is its probe port - so it is reachable from the
whole cluster by default, and an egress rule for 80/443 would turn a service
anyone can POST to into a way of fetching arbitrary URLs. The price is the
remote-asset half of HTML conversion: inline content converts, images the page
would have fetched silently do not. That degrades a PDF instead of failing a
pod, so nothing alerts on it, which is why it is in the template header, in
values.yaml and in NOTES.txt, with extraPorts: [80, 443] named as the knowing
opt-in.
RSS-BRIDGE, SEARXNG and YTDLP-WEB-PLAYER get the open internet on their web
ports, because reaching other people's servers IS the application and this
object cannot name a host. Said plainly in each, so none of them reads
stricter than it is. What the cap still buys is real: no other outbound port,
so a compromised pod reaches no database, no mail server and no SSH anywhere.
APACHE-TIKA and GOTENBERG render no Ingress - their consumers are other pods,
in other namespaces here - so neither gets an ingressController value and both
say in NOTES.txt that narrowing probeSources means listing the consumers'
namespaces in allowedNamespaces in the same change, or extraction and
conversion stop.
YTDLP-WEB-PLAYER names the gap this convention has: its oauth2-proxy subchart
renders its own Deployment with its own labels and ships no policy, so with the
proxy enabled the pod that actually faces the Ingress is unrestricted in both
directions. Nothing in this chart can change that - an upstream chart is
consumed as it comes - so it is written down instead.
ci/outline/test-values.yaml gains egress.extraPorts: [5556]. The CI dex runs
there rather than on 443, and Outline fetches the discovery document at boot -
so this is the chart's documented escape hatch used for exactly the case it was
written for, and the one place in the repo where the cap's upgrade risk is
actually exercised.
Part of #5
Sets seccompProfile.type: RuntimeDefault in the pod security context, 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.
Verified in k3d against real extractions rather than a reachable port:
the -full image loads its parsers dynamically, so a blocked syscall would
surface as HTTP 200 with empty text, not as an error. The PDF parser, the
HTML parser and the detector/metadata path all return the expected
content under the filter, and the kernel reports Seccomp: 2 (filter mode)
inside the container.
Major bump: runtime behavior changes.
Refs #84
- apache-tika, gotenberg, cyberchef, homeassistant, patchmon: additive env
value blocks rendered through tpl (value, secretKeyRef and configMapKeyRef
forms), following the template-chart/outline pattern; patchmon gets separate
blocks for the server container and the guacd sidecar.
- homeassistant: ingress.className now defaults to nginx; an empty className
omits ingressClassName from the rendered Ingress, so the flexible upstream
ingress style stays intact.
- outline, paperless-ngx: remove the ingress.clusterIssuer defaults
(letsencrypt / letsencrypt-issuer) - the value is now strictly required,
consistent with the repo-wide ingress standard; CI test-values set it
explicitly.
Chart bumps: apache-tika 7.2.0, gotenberg 4.2.0, cyberchef 5.2.0,
patchmon 5.2.0, homeassistant 4.2.0 (minor); outline 5.0.0,
paperless-ngx 10.0.0 (major).
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
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.
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.
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
