Two changes to the reference implementation, both of which every chart copied from it inherits.
Render fix (part of #157): multiplyQuantity turned its input into a string with printf "%v". The null-safe fallback helpers pass values through fromYaml, which parses every number as float64, and Go's "%v" switches float64 to exponential notation from about 1e6 upwards - so a bare byte count like 1048576 arrived as "1.048576e+06" and the suffix check aborted the render. A new xxx.formatNumber helper forces plain decimal notation on both the input and the non-integer product; strings like "512Mi" pass through untouched. This is the canonical fix agreed for the issue, taken over verbatim, because multiplyQuantity is the same copy in every chart and a private variant would create drift instead of a solution. The toYaml/fromYaml round-trip is deliberately not touched: it is not the cause.
NOTES.txt (part of #43): the scaffold now carries the reference NOTES.txt - a placeholder-carrying template, not finished prose. It renders the access URL from ingress.domain (no real domain anywhere), names which fields the 1Password item must carry, and prints the chart's traps: the placeholder image, the fact that both a Deployment and a StatefulSet render, and that no checksum/secret-ref means a secret change restarts nothing here. Output is conditional on the values actually set.
appVersion unchanged; minor bump because both changes are additive.
BentoPDF computes entirely in the visitor's browser; the container only serves
static files through nginx. The chart is therefore close to cyberchef - same
nginx-unprivileged base, uid 101, port 8080, probes on "/" - with four
differences that shaped the design.
Runtime config.json. The one setting reachable at runtime is the tool list.
It is a static file in the middle of the web root, so it is mounted by
subPath: a directory mount would hide the whole application. subPath mounts
are never refreshed by the kubelet, which makes the checksum/config annotation
(#82) load-bearing rather than decorative. bentopdf.config is passed through
verbatim, like searxng's settings, so a key upstream adds tomorrow is a values
change and not a chart change.
Three env switches that would kill the pod. PORT, DISABLE_IPV6 and
ROBOTS_NOINDEX are implemented as "sed -i" against files in the image, run
under "set -e" in /docker-entrypoint.d/, and the base image's entrypoint
aborts when one of them fails. With readOnlyRootFilesystem: true the pod
therefore never starts instead of ignoring the switch - measured in k3d as
CrashLoopBackOff, exit 1, "sed: can't create temp file
'/etc/nginx/nginx.confXXXXXX': Read-only file system". None of the three is
offered as a first-class value; values.yaml names the failure picture and the
escape hatch (env block plus readOnlyRootFilesystem: false).
Writable paths were measured, not copied from the upstream chart.
/etc/nginx/tmp holds the pid file and /var/cache/nginx is where nginx creates
its temp directories at startup - without it the master aborts with
'mkdir() "/var/cache/nginx/client_temp" failed'. /var/run is deliberately not
mounted: the running pod proves it is unnecessary.
Everything else about BentoPDF is a build-time argument and out of reach for
any chart; values.yaml says so explicitly rather than leaving it to be
discovered. Two accepted consequences are named there too: some tools fetch
WASM modules from a public CDN at runtime, and the served pages carry a
canonical link to the vendor's site.
Fixes#174
The comment on the probe block said a probe on "/" would "risk" a 429 once
the limiter is on. It was measured against a reachable Valkey in k3d and it
does not risk it, it collects one: "/" answered 429 while /healthz answered
200. Comment only, no rendered change.
SearXNG as a stateless Deployment plus a settings ConfigMap, with the four CI
steps a new chart needs: publish workflow, change-app-version choice list,
ci/searxng/ fixtures and a renovate.json5 block.
Three points where the chart is not a cyberchef with another name:
* The image entrypoint writes settings.yml into /etc/searxng only when the
file is missing. The chart always mounts one by subPath, so the copy and
the random-secret sed never run and the container needs no write access
there - which is what allows readOnlyRootFilesystem: true.
* The signing key is a required OnePasswordItem, not a ConfigMap key. It
signs the settings cookie and the image-proxy URLs, and the entrypoint's
self-generating fallback cannot fire here, so without it the instance would
run on the literal "ultrasecretkey" - which webapp.py refuses with exit 1.
* All three probes use /healthz, the only path the bot detection lets through
unconditionally. Measured: with the limiter active, "/" answers 429 while
/healthz still answers 200.
ingress.domain is read a second time outside the Ingress template, for
SEARXNG_BASE_URL, and carries its own required() there - so it stays
mandatory with the Ingress switched off.
The Renovate versioning regex deviates from the plan on the issue and matches
the commit hash WITHOUT capturing it. Renovate parses a "build" group with
Number.parseInt, so a hash becomes the digits leading it; measured on
renovate 41.173.1 and 44.48.0, the planned form reports an image pushed
earlier the same day as an update to a newer one. Reasoning in the block and
in README.
The failure path prints container logs, and an app may print a value it was
given - gluetun logs its Wireguard address on startup. diagnose() now runs
through a filter that replaces the values of the declared REQUIRED_ENV
variables with the variable name. GitHub masks them as well, but that is the
platform's promise rather than this harness's, and the script runs locally too,
where nothing masks anything.
freesailarr was excluded from the install-test because gluetun never becomes
healthy without a real Wireguard key and no app container behind its kill
switch can become Ready. The green "Install-test freesailarr pass" was a
25-second SKIP on the most complex chart in the repo - a signal that proved
nothing.
With a CI-only Mullvad key in 1Password the reason is gone:
- ci/run-install-test.sh learns a general rule: ci/<chart>/fixtures.env.yaml is
rendered with envsubst before it is applied, restricted to the variable names
a chart declares in REQUIRED_ENV. A missing or empty declared variable fails
the run loudly and names the variable - it never skips the chart.
- The install-test job loads the key from 1Password Connect for freesailarr
only, following the pattern publish-helm-chart.yml documents: values via
steps.<id>.outputs.*, mapped into the step's own env, quoted, with ":?"
guards that name the missing op:// field before a cluster is created.
- Fixtures for freesailarr: three media claims, the gluetun secret template
with variable names only, firewallOutboundSubnets so the kill switch does not
block cluster DNS, and INSTALL_TIMEOUT=900 for nine containers.
freesailarr/Chart.yaml goes 3.0.0+up1.0.0 -> 3.0.1+up1.0.0. That bump is
deliberately empty of content: the install-test matrix follows changed chart
directories, and without it this PR could not run the test it adds.
Both are documentation only - the rendering is byte-identical to the previous
commit.
The *arr probes: with a UrlBase set, radarr/sonarr/prowlarr answer the bare
/ping with 307 and Location: /<urlbase>/ping, not 200. The probes keep passing
because the kubelet counts 200-399 as success (9/9 Ready, 0 restarts), so the
probe paths stay at /ping and are valid in both ingress shapes. Recorded so
nobody reads the 307 as a fault.
Bazarr under a sub-path without its manual base URL: it does not answer 404.
It returns its index page for every unknown path, so /bazarr/ and
/bazarr/<asset> both come back as 200 text/html of identical length - the page
loads, the assets silently arrive as HTML, and nothing looks like an error.
The content type is the tell, not the status code.
Adds a second, optional ingress shape and fixes the download target of
qBittorrent. The existing per-app-host shape stays the default and renders
unchanged.
Shared domain (#167)
Setting ingress.host moves every app without a host of its own into one
Ingress object with one path each (<app>.ingress.path, default /<app>), one
TLS secret and therefore one DNS name and one certificate for the whole
stack. A per-app host always wins and keeps its own object, so mixed
operation needs no extra values.
The apps differ in what they can do under a sub-path, and the chart follows
that rather than pretending they are alike:
- radarr, sonarr, prowlarr get <APP>__SERVER__URLBASE from the chart, but
only when their own env block does not already carry the variable.
- bazarr has no environment variable for its base path and stays one
documented manual step (Settings -> General -> Base URL).
- qbittorrent has no base path at all and renders a second object on the
same host with a prefix-stripping rewrite. It repeats the same TLS secret
name and deliberately omits the cert-manager annotation, so both objects
state their own TLS while only one certificate is requested.
- seerr has no base path either and cannot be rewritten, so it is pinned to
"/" and a fail refuses any other path. A second fail refuses two apps
claiming the same path.
qBittorrent save path (#166)
Without Session\DefaultSavePath qBittorrent writes to its built-in default
/config/Downloads - the 1Gi config volume. It fills within minutes, every
torrent goes to "errored" and qBittorrent can no longer write its own
metadata to BT_backup, so a restart in that state costs the torrent list.
The init container (renamed qbittorrent-config-interface ->
qbittorrent-config-seed, since it no longer only sets the interface) now
seeds qbittorrent.savePath, default /downloads. Unlike the interface binding
it is inserted ONLY when the key is absent and never replaced: a path changed
in the WebUI is a legitimate operator decision and must survive a restart.
This is the reason for the major bump: an installation that never set the
path writes somewhere else after the upgrade.
Documentation
NOTES.txt and the media block in values.yaml now spell out why a shared claim
with three subPaths does not produce hardlinks: the kernel compares the
vfsmount in do_linkat, not the superblock, so two bind mounts of one
filesystem are EXDEV - while stat reports the same device number on both
sides and suggests the opposite. The layout that would work (one claim, one
mount, categories as sub-directories) is named as a possibility; the chart
cannot express it today.
README.md gains the shared domain as the second admissible ingress shape of
the style guideline.
media.downloads, media.movies and media.tv rendered three fixed volume
entries, one per category. Two categories on the same existingClaim
therefore produced two pod volumes with an identical claimName, and such a
pod never starts: it stays in Init:0/1 without a single kubelet event
(measured on RKE2/Longhorn, RWO and RWX alike).
The volume list is now deduplicated by claim name. A new mediaVolumeName
helper names the entry after the first ENABLED category in the fixed order
downloads, movies, tv that carries the claim; the other categories mount
that same entry and differ only in their subPath. The restriction to
enabled categories matters because the three entries render under
different conditions - a canonical owner whose entry is not rendered would
be a dangling reference.
With three distinct claims the chart renders byte-identically to 2.0.1,
hence a patch bump.
Also corrected in the values documentation, after measuring instead of
assuming: the kubelet creates missing subPath directories itself, but they
inherit the claim root's mode, and fsGroup cannot be relied on to fix that
- Longhorn's fsGroupPolicy (ReadWriteOnceWithFSType) skips fsGroup on RWX
claims entirely. What has to hold is that the claim root is writable for
PUID/PGID. No chown or init container was added.
Closes the three-step round that carried the #99 null-safety to every Java
line. Pure restoration of the directory to the newest line:
version: 4.0.0+up2026.8.2.java17 -> 4.0.1+up2026.8.2.java21
appVersion: "2026.8.2-java17" -> "2026.8.2-java21"
minecraft.version: "1.20.1" -> "1.21.1"
Nothing changes in content, and that is not a claim but a measurement. Against
the java21 state published from #156, the ENTIRE chart tree differs in exactly
one line - the chart version - and .Chart.Version is not read by any template,
so the rendering is byte-identical:
4.0.0+up2026.8.2.java21 (published) -> this chart:
file tree: 1 differing line, Chart.yaml version
rendering: byte-identical (CI values, serverpack init container enabled)
main (java17) -> this chart:
exactly TWO differences, both the line selection itself -
image itzg/minecraft-server:2026.8.2-java17 -> :2026.8.2-java21 and
env VERSION 1.20.1 -> 1.21.1.
Why 4.0.1 and not 4.0.0: 4.0.0+up2026.8.2.java21 is already in the registry
from #156, and helm push overwrites an existing OCI tag without complaint. The
version check in validate-charts.yml does not catch this - it compares only
against github.base_ref, where the version would read java17, so a republished
4.0.0 would pass the gate and silently overwrite the published artifact. Tracked
as #160.
What this round achieves, measured across the three published line states:
templates/ and values.schema.json are byte-identical on java8 (f7047b8), java17
(2b22ce5) and java21 (this chart); values.yaml differs only in minecraft.version
and the comment naming the appVersion; and all three now carry initImage
alpine:3.24, so the bump that had reached only java21 is no longer missing on
the other two. All three lines therefore run the same hardening, the same three
exec probes, the same resources handling and the same null-safe fallbacks.
Left untouched on purpose: the float64 quantity finding (#157) and seccompProfile
(#161) - the latter has to be pulled through all three lines and has its own
unknowns in gosu and the serverpack init container.
Refs #99
Third of three line publications that carry the #99 null-safety to every Java
line. Templates and schema are the same for all three lines; only the
line-selecting fields change:
version: 4.0.0+up2026.8.2.java8 -> 4.0.0+up2026.8.2.java17
appVersion: "2026.8.2-java8" -> "2026.8.2-java17"
minecraft.version: "1.12.2" -> "1.20.1" (Java 17 runs
Minecraft 1.18-1.20.4)
What the diff does NOT show, same as for java8: the java17 line was last
published as 3.0.0+up2026.8.2.java17, and since then main also moved the
serverpack init image from alpine:3.22 to alpine:3.24 (commit 5a35ea4, which
landed on the java21 line only). That bump rides along here.
It is invisible in the diff against main, because relative to main the file
already says 3.24 - the java8 publication in #159 brought it there. Relative to
what a java17 release actually runs today it is a base-image change, so it is
named here rather than left to be discovered.
Measured against ci/minecraft-server/test-values.yaml with the serverpack init
container enabled, compared structurally (documents paired by kind/name,
recursive over keys) instead of line by line:
3.0.0+up2026.8.2.java17 (published) -> this chart:
exactly ONE difference, initContainers[0].image alpine:3.22 -> alpine:3.24.
main (java8) -> this chart:
exactly TWO differences, both the line selection itself -
image itzg/minecraft-server:2026.8.2-java8 -> :2026.8.2-java17 and
env VERSION 1.12.2 -> 1.20.1.
Hardening, the three exec probes, resources and the init.sh chown are unchanged,
which is what the null-safety was built to do: it changes what an ERASED block
renders, not what the defaults render.
At file level the line invariant holds exactly - against main's tree the only
differing files are Chart.yaml and values.yaml, in the three line fields plus
the comment naming the appVersion. _helpers.tpl, values.schema.json and both
templates are byte-identical across the lines.
The null-safety itself is not re-swept - #156 proved it on identical templates.
Confirmed once on this build that it carries: erasing both security contexts
renders byte-identical to the defaults.
Left untouched on purpose: the float64 quantity finding (#157), because
multiplyQuantity is the same copy in all 21 charts and a single-chart fix would
create drift, and seccompProfile (#84), which changes runtime behaviour and
belongs in its own change.
Refs #99
Second of three line publications that carry the #99 null-safety to every Java
line. The chart is published once per line, the templates and the schema are
the same for all three, and only the directory's line-selecting fields change:
version: 4.0.0+up2026.8.2.java21 -> 4.0.0+up2026.8.2.java8
appVersion: "2026.8.2-java21" -> "2026.8.2-java8"
minecraft.version: "1.21.1" -> "1.12.2" (Java 8 runs
Minecraft <= 1.16.5)
What the diff does NOT show, and what this commit therefore has to say out
loud: the java8 line was last published as 3.0.0+up2026.8.2.java8, and since
then main also moved the serverpack init image from alpine:3.22 to alpine:3.24
(commit 5a35ea4, which landed on the java21 line only). That bump rides along
here. It is invisible in this PR's diff, because relative to main the file
already says 3.24 - but relative to what a java8 release actually runs today it
is a base-image change, and the cluster side has to know.
Measured, rather than assumed. Rendered against ci/minecraft-server/test-values
with the serverpack init container enabled and compared structurally (documents
paired by kind/name, recursive over keys) instead of line by line:
3.0.0+up2026.8.2.java8 (published) -> this chart:
exactly ONE difference, initContainers[0].image alpine:3.22 -> alpine:3.24.
main (java21) -> this chart:
exactly TWO differences, both the line selection itself -
image itzg/minecraft-server:2026.8.2-java21 -> :2026.8.2-java8 and
env VERSION 1.21.1 -> 1.12.2.
Nothing else moves: the hardening, the three exec probes, the resources and the
init.sh chown are unchanged, which is what the null-safety was built to do (it
changes what an ERASED block renders, not what the defaults render).
The null-safety itself is not re-swept here - #156 proved it on identical
templates. Confirmed once on this build that it carries: erasing both security
contexts renders byte-identical to the defaults.
The float64 quantity finding (#157) is deliberately untouched, per its own
issue: multiplyQuantity is the same copy in all 21 charts and a single-chart
fix would create drift.
Refs #99
The last open gap of #99. minecraft-server was the one chart of 21 where an
erased security context removed the hardening in silence: it never got the
defaultedDict helper, the StatefulSet rendered .Values.securityContext.pod
straight through toYaml, and the schema typed securityContext.pod as a strict
"object" without required. Measured against ci/minecraft-server/test-values.yaml
on 3.0.1:
--set securityContext.pod=null --set securityContext.container=null
-> helm exit 0, no schema error, "securityContext: null" for BOTH the pod and
the container - no runAsNonRoot, no readOnlyRootFilesystem, no dropped
capabilities, in a chart with a PVC.
Bitter place for it: the README lists this chart as the pilot for #68. It got
its schema early and was therefore never caught by the later null-safety wave.
Both halves are added, because they cover different cases. For a key WITH a
chart default Helm's coalescing deletes the null before validation ever sees
it, and only the defaultedDict fallback catches that; for a key WITHOUT one
(server.resources.limits) the null survives into validation, where the strict
"object" aborted the render. Now widened to ["object","null"].
The fallback table reproduces THIS chart's defaults, deviations included:
uid/gid pinned to 1000 (the image's minecraft user - starting as it directly
takes the entrypoint's non-root branch, which skips the recursive chown of
/data and the write to /etc/nsswitch.conf that a read-only root filesystem
would reject), fsGroupChangePolicy OnRootMismatch (a recursive chown of a 32Gi
world on every start costs minutes), the explicit empty capabilities.add list,
and all three probes as exec probes running the image's mc-health script - this
image has no HTTP endpoint, so a probe default rebuilt as httpGet would leave
the workload with no working probe at all. The startup budget stays 15s x 80.
server.resources goes through the same helper while keeping its memory request
deliberately unset, so it is still derived from the JVM heap.
Also, the same class one level down: init.sh chowned the migrated serverpack to
a hardcoded 1000:1000 while the uid it has to match was overridable. Both reads
now go through the same helper, so they cannot disagree. With the chart defaults
the rendered script is unchanged, so checksum/config does not move and no
existing pod rolls.
minecraft.resources.storage and .memory stay deliberately not null-safe: an
erased value yields an invalid PVC or an unparseable quantity, which is the loud
class #99 excludes.
Evidence, all against ci/minecraft-server/test-values.yaml unless noted:
- the reported call now renders the defaults, byte-identical to the
unmodified rendering. Fallback, not rejection.
- rendering with securityContext, all three probes and server.resources set
to null is byte-identical to rendering the chart defaults - which is what
keeps the table and values.yaml in sync instead of leaving it to discipline.
- no regression: rendering before and after the change is byte-identical, on
the CI values, on the chart defaults, and with curseforgeServerpack enabled
(the init-container path the CI values do not exercise). Confirmed
structurally too, not only by raw diff.
- partial nulling, 14 keys swept one at a time. On 3.0.1 twelve of them
changed the rendering silently, including capabilities (the container kept
every default capability instead of dropping ALL) and requests (cpu and
ephemeral-storage disappeared entirely). On 4.0.0 all fourteen render
identical to the defaults.
- explicit false and 0 still win over the defaults; a scalar in a mapping slot
is still rejected, now naming the values path.
Major bump: erasing one of these blocks used to change the rendered workload
and now does not, which is a runtime behaviour change. appVersion is untouched.
Refs #99
The previous wording named freesailarr as a documented exception but closed on
"the field is omitted, lint still exits 0", which reads as a general licence to
drop the icon. The rule is now stated with its criterion and its reach: the
exception exists because the chart has no single upstream whose logo the icon
could be, it is the only chart in the repo without one, and a single-upstream
chart missing an icon is a missing icon rather than an exception.
Retrofits the repo-wide groundwork that #59 deliberately left out to keep the
reviewed scope. Chart 2.0.0+up1.0.0 - a major, because seccompProfile changes
runtime behaviour; appVersion stays the freely chosen marker 1.0.0.
values.schema.json (#68). The largest schema in the repo: nine app blocks with
probes, resources, security contexts, env and image. additionalProperties is
false on every chart-owned level; the objects that go verbatim into the pod
spec stay open. It rejects a mistyped app name, a mistyped key at any depth and
ingress.domain - the key #59 removed, which until now would have been accepted
in silence.
Null safety (#99), both halves, because they cover different cases. The
defaultedDict helper catches a key WITH a chart default, where Helm's
coalescing deletes the null before the schema ever sees it; the widened
["object","null"] types catch a key WITHOUT one, where the null survives into
validation. Measured on the old chart: radarr.securityContext: null rendered
"securityContext: null" - the whole hardening gone - and
securityContext.capabilities: null dropped the capability block entirely, so
the container kept every default capability instead of dropping ALL. Both
render green.
The fallback table reproduces THIS chart's defaults including its deviations:
the five linuxserver.io containers keep runAsNonRoot unset and a writable root
filesystem so their s6 init can drop to PUID/PGID, flaresolverr keeps its
numerically pinned uid, gluetun keeps NET_ADMIN, and recyclarr keeps its exec
probes. Restoring the "clean" standard there would put the linuxserver
containers back on the image's uid 911 - the failure calibre-web-automated hit.
The sync between table and values.yaml is not left to discipline: rendering
with every block of the silent class explicitly set to null is byte-identical
to rendering the defaults, which is how a drift shows up.
seccompProfile RuntimeDefault (#84) in the pod context, so it covers the init
container too. Trivy's KSV-0104 drops from ten findings to none.
NOTES.txt (#43) covering what actually bites: the pod is not Ready until the
tunnel is up, the two fields the 1Password item needs, the warning when
firewallOutboundSubnets is unset, the immutable volumeClaimTemplates, and the
measured fact that imports do not hardlink across the media categories.
Also, from point 5 of the plan: checksum/config does not apply - the chart has
no ConfigMap - but checksum/secret-ref does, and was missing. Helm never sees
the secret's contents, yet it does see which op:// item the OnePasswordItem
points at, so repointing secrets.gluetunSecretRef now restarts the pod instead
of leaving the old credentials running.
README: the #43 status line was stale (it still claimed only homeassistant
ships NOTES.txt), and the mandatory-icon rule now records freesailarr as a
documented exception - #59 dropped the icon and did not amend the rule.
linuxserver/qbittorrent still carries 14.3.9 and 20.04.1 from earlier tagging
schemes. Docker versioning sorts both above every real release, so Renovate
offers them as major updates - PRs #152 and #153 are exactly those, and they
would have to be closed by hand again after every lookup.
They cost more than the noise. Renovate fills the major bucket once, so while a
stray occupies it the genuine major is never offered at all: measured from
currentValue 4.6.4, the unconstrained lookup returns 4.6.7 and 20.04.1, and
never mentions 5.2.3.
Both are excluded by name. A bound such as "<10" would reject a genuine major
sooner or later, whereas two finished artifacts cannot grow and so cannot mask
a release that does not exist yet. A shape-based filter was tried first and
measured out: requiring a non-padded minor drops 20.04.1 and simply promotes
14.3.9 into its place.
Verified with renovate 44.41.0 (dry-run=lookup) against the live registry:
currentValue 5.2.1 -> [5.2.3 (patch)], both strays gone
currentValue 4.6.4 -> [4.6.7 (patch), 5.2.3 (major)]
The second fixture is the guard the nginx rule taught us to run - it proves the
filter does not silently empty the update list. A full run over the real
repository with the real config confirms it in place: qbittorrent offers 5.2.3
only, nginx is unchanged, and no docker dependency carries a skipReason or a
warning.
docker.io/busybox and docker.io/library/busybox resolve to the same image on
Docker Hub, and the short form is the spelling the rest of the fleet will use
when the remaining unqualified official images (paperless-ngx, matrix-synapse,
minecraft-server) are qualified in the #84 follow-up.
Verified: the rendered output differs in exactly this one line, and a Renovate
lookup against the real chart files (44.41.0, official container, dry-run
lookup) still extracts all ten images through helm-values with no skipReason
and no warnings - docker.io/busybox included, whose candidate list stays empty
because 1.38.0 is current.
main qualified five charts' image references in 6c73ef8 on the same day this
chart would otherwise arrive carrying the pattern that was just cleared out.
The seven Docker Hub names now say where they come from: qmcgaw/gluetun, the
five linuxserver.io images and the busybox init image, the last as
docker.io/library/busybox since it is an official image. The three ghcr.io
names were already qualified - checked rather than assumed.
Verified with Renovate 44.41.0 in the official container (RENOVATE_PLATFORM=
local, RENOVATE_DRY_RUN=lookup) that the prefixed form still resolves under the
built-in helm-values manager, since that manager is the only thing keeping
these images updated: it extracts all ten, datasource docker, no skipReason and
no warnings, and returns concrete candidates for eight of them. A control run
against the unqualified form produced byte-identical results, so the prefix
changes nothing about what Renovate offers.
Trivy's trusted-registry check (KSV-0125) drops from ten findings to none, which
is what the registry list in ci/trivy/data/ksv0125.yaml documents as the point
of writing images this way.
Chart metadata: the icon was gluetun's logo and the description opened with a
list of four of the nine projects, both suggesting a "main app" the stack does
not have. The description now names none of them, and the icon field is omitted
rather than filled with another project's logo - every other chart's icon is its
one upstream's, and this chart has no such upstream. helm lint --strict notes
"icon is recommended" as INFO and still exits 0.
Rendered output differs in exactly the seven image prefixes and nothing else.
The previous commit moved every image tag into values.yaml but left appVersion
described as a marker "for the gluetun line", to be updated together with
gluetun.image.tag. That still asserts a coupling the chart does not have, and
the value v3.41.1 confirmed it at a glance.
appVersion is now 1.0.0 (version 1.0.0+up1.0.0): the chart's own version
marker, freely chosen and tied to no upstream. The texts say that instead of
the old coupling in Chart.yaml, values.yaml and the two README passages. The
README's remaining true statement is kept but generalized - renovate-bump-chart
bumps the patch level on an unchanged appVersion for all nine images alike,
which is not a gluetun special case.
Also corrected on the way: the busybox init image comment claimed it was
"pinned independently of appVersion (which tracks gluetun)". Neither half holds
any more - appVersion tracks nothing, and every image in the chart is pinned
the same way.
No functional change: the rendered gluetun image is qmcgaw/gluetun:v3.41.1
before and after.
The chart bundles nine independently versioned upstreams, and eight of them
were already pinned in values.yaml while only gluetun took its tag from
appVersion. That split had no upside: it made gluetun the one image Renovate
could not reach through the built-in helm-values manager, and it implied a
"main app" the stack does not have.
gluetun now carries gluetun.image.repository/tag like every other image, and
the StatefulSet renders it from there. No tag comes from appVersion any more.
Renovate picks all nine up through helm-values - the manager the repo already
relies on for sidecar images - and ci/renovate-bump-chart.sh bumps the chart
version with each update.
Consequences, all documented where they bite:
- renovate.json5 deliberately gets no app-version block for this chart. One
would either duplicate the helm-values updates or rewrite an appVersion that
selects no image. The absence is commented so it does not read as an
oversight.
- freesailarr leaves the change-app-version.yml choice list. That workflow
rewrites appVersion and republishes, which for this chart would change no
deployed image at all.
- appVersion becomes a hand-maintained marker for the gluetun line. Since
renovate-bump-chart.sh bumps the patch level on an unchanged appVersion, a
gluetun update has to be paired with a hand edit of appVersion, or the +up
suffix stops describing what the chart deploys. Noted in Chart.yaml,
values.yaml and README.
FIREWALL_INPUT_PORTS does not open the app ports inside a pod network. gluetun
detects the pod's own subnet and inserts an INPUT accept for it ahead of the
per-port rules, and every packet arriving at the pod IP matches that rule by
destination. Measured with the packet counters: 50 fresh requests moved the
subnet rule from 306 to 356 packets while every --dport rule stayed at 0 since
container start. A port that listens but is not in the list (gluetun's control
server on 8000) is reachable from another pod all the same.
The variable is kept - it is the explicit statement of which ports are meant to
be reachable, and the subnet detection is gluetun's behaviour rather than a
guarantee of this chart - but the comments no longer claim the traffic would be
dropped without it.
Second correction, same run: the /tmp/gluetun emptyDir fixed the "open ...
permission denied" failure, but gluetun also chowns the file, which needs
CAP_CHOWN. With all capabilities but NET_ADMIN dropped that logs "chown
/tmp/gluetun/ip: operation not permitted" on every VPN restart. The file is
written and the public IP is persisted, so this is a log line rather than a
failure, and granting CHOWN to silence it would widen the container's
capabilities for nothing. Noted where the mount is declared.
The runtime test contradicted the assumption behind the change. Kubernetes
turns every volumeMount into its own bind mount, and link()/rename() across two
mount points fails with EXDEV even when both sides are the same claim on the
same device: in the radarr container /downloads and /movies both report device
65025 and resolve to the same PV directory, yet linking between them fails with
"Cross-device link", while the identical link succeeds when the claim root is
mounted once and the categories are sub-directories under it.
It is not a property of subPath - two plain mounts of the same claim without
any subPath fail the same way, so the chart never supported cross-category
hardlinks and this change does not regress anything. But the comment claimed a
benefit the chart does not deliver, so it now states the measurement instead:
subPath buys the layout (one claim, one sub-directory per category), not
hardlinked imports. Getting those needs a single mount containing all
categories, which is a change to the mount layout rather than a values setting.
Two defects kept the publish broken after the load-secrets-action v5 bump
in #140.
v5 no longer exports the loaded values as environment variables for later
steps the way v4 did; only the step outputs carry them. Every
"${{ env.JK_CR_* }}" reference therefore resolved to an empty string from
that bump on, and nothing reported it - the loading step logs "Populating
variable" and stays green either way. #149 moved three of the four
references to steps.<id>.outputs but left "-u ${{ env.JK_CR_USERNAME }}"
on the old form, and piped the username instead of the token into
--password-stdin.
The second defect is why this surfaced as a terminal error: an empty value
collapsed into a missing argument instead of failing. With an empty
username, "-u" swallowed the following "--password-stdin", helm stopped
reading the password from stdin, prompted interactively and died with
"inappropriate ioctl for device".
All four values now come from steps.<id>.outputs, are mapped into each
step's own env block and used as quoted shell variables guarded with ":?".
An empty or unset value aborts the job naming the op:// path to fix,
quoting keeps it from shifting arguments, and the token no longer appears
on the command line.
ci/run-trivy-config.sh renders every changed chart before scanning it and exits
non-zero when the render fails - which it does for freesailarr, because the
chart is excluded from the install-test and therefore has no
ci/freesailarr/test-values.yaml to fall back on. The scan job would go red
without ever scanning anything.
The file supplies only the values the chart declares required (secret ref,
cluster issuer, the three media claims and one ingress host per app, since the
chart has no global ingress.domain) and nothing that would alter the security
posture the scan is meant to look at.
Three review changes to the freesailarr chart.
Ingress: the chart no longer derives hosts as <app>.<ingress.domain> from one
Ingress object. The global ingress.domain is gone; every app carries its own
<app>.ingress.host and renders its own Ingress <release>-<chart>-<app>-ingress
with its own TLS secret tls-<release>-<chart>-<app>-ingress. The hosts are
therefore independent and may live in unrelated domains. The host is required,
but the required() call sits inside the loop over the *enabled* app ingresses,
so switching an app's ingress off must not make the chart demand a host for it.
clusterIssuer, className and annotations stay global defaults and are
overridable per app; an explicitly set per-app value wins (nil check instead of
"default", so an empty override is honoured).
Media: media.<category>.subPath mounts a sub-directory of the claim instead of
its root, default null (claim root = previous behaviour). The same
existingClaim may back all three categories with different subPaths. That is
the point rather than cosmetics: Radarr and Sonarr import by moving, and a move
within one filesystem can be a hardlink instead of a copy - across volume
boundaries every import duplicates the file.
Services: the collective Service with named ports is replaced by one ClusterIP
Service <release>-<chart>-<app>-service per enabled app that listens on a port,
flaresolverr included; recyclarr serves no port in daemon mode and gets none.
Each ingress points at its own app's service. All containers share gluetun's
network namespace, so the services differ only in their port - they provide
stable per-app DNS names, not network separation. The StatefulSet's governing
serviceName no longer names a removed object.
gluetun logs "clearing public IP data: open /tmp/gluetun/ip: permission
denied" every few seconds and never persists its public IP. It creates
/tmp/gluetun with mode 0644, i.e. without the execute bit needed to enter
the directory; it runs as root, but with all capabilities except
NET_ADMIN dropped there is no DAC_OVERRIDE left to paper over the missing
bit. An emptyDir provides the path with usable permissions.
qBittorrent had no network interface configured, so libtorrent listened
and announced on every interface of the shared pod network namespace -
including eth0 (the pod IP) and loopback. gluetun's kill switch drops
exactly those packets, so trackers answered with "skipping tracker
announce (unreachable)" or timed out, no peers were found and torrents
stalled at 0 bytes in stalledDL. Beyond the stall this is a leak: without
the binding qBittorrent also listens on the pod IP, i.e. reachable past
the tunnel.
The setting only exists in the persisted config file, which qBittorrent
creates itself on first start, so an init container seeds it before the
app comes up. The edit is idempotent and preserves existing user
settings: it replaces the keys if present, inserts them into the
[BitTorrent] section if missing, and creates file or section if needed.
The interface is configurable via qbittorrent.networkInterface (default
tun0); emptying it drops the init container.
With readOnlyRootFilesystem the s6-overlay init cannot rewrite
/etc/passwd, so the containers silently kept the image's built-in
uid/gid 911 instead of the configured PUID/PGID (verified at runtime) -
breaking ownership on the shared media volumes. Drop the now-unneeded
/run and /tmp emptyDirs; deviation documented in values.yaml.
Short tunnel re-negotiations recover internally; a kubelet restart only
prolongs the outage while the kill switch already blocks all egress.
Liveness budget 60s, readiness stays at 30s.
Replace the upstream-recommended postStart hook, which runs
concurrently with the entrypoint and loses the race (observed: it
deleted the ip rule the restarted gluetun had just created, leaving the
container in a permanent CrashLoop behind the kill switch). A command
wrapper now removes stale table-51820 rules and the leftover tun
device deterministically before exec'ing /gluetun-entrypoint, covering
container restarts after unclean exits.
An uncleanly exited gluetun leaves its ip rule in the shared pod
network namespace; the restarted container then fails forever with
'adding ip rule 101: file exists' while the kill switch keeps blocking
all egress. Apply the upstream-recommended Kubernetes fix: a postStart
hook dropping table-51820 rules.
