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.
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.
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.
The image copies and patches the chromedriver binary to the hardcoded
path /app/chromedriver at startup (no env override exists) and writes
chromedriver caches under /app, so readOnlyRootFilesystem cannot hold;
deviation documented in values.yaml. Reverts the HOME=/tmp workaround,
which only covered the cache path, not the binary patching.
The image declares its non-root user by name only, which the kubelet's
runAsNonRoot check cannot verify (CreateContainerConfigError); pinning
the uid/gid numerically satisfies the check.
