Both Deployments' rolling update briefly ran an old+new pod pair on the same
node (node-role: storage), sharing the same config storage (qbittorrent's PVC,
jdownloader's hostPath) -- both apps are effectively singletons that lock
their config directory, so the new instance conflicted with the still-running
old one:
- qbittorrent: hit a known qbittorrent:5.2.0 image bug (linuxserver/
docker-qbittorrent#432) where a stale WebUI lockfile prevents the server
from ever binding its port while a second instance is present -- surfaced
as the new pod's readiness probe getting "connection refused" indefinitely.
On top of that, my livenessProbe (30s/30s) was killing the container
(exitCode 137) before qbittorrent had any chance to come up at all. Dropped
the livenessProbe (readiness alone can never kill a container, only mark it
not-ready) and loosened the readinessProbe timing.
- jdownloader: the new pod's app process detected the old instance's lock in
the shared /data/jdownloader hostPath and exited cleanly (exitCode 0) rather
than run a duplicate copy -- nothing to do with probe timing.
Both Deployments now use `strategy: Recreate` instead of the RollingUpdate
default, so any future rollout fully stops the old pod before starting the
new one -- this is the actual fix (matches the pattern immich.yaml already
used). Applying this will briefly restart both currently-running pods to
verify it.

Stage 7 of REFACTOR_PLAN.md (findings #16). Covers dashy, glances,
ca-installer, authentik-proxy-outpost, jellyfin, qbittorrent/jdownloader main
containers (their gluetun sidecars already had probes), and all 4 Immich
Deployments -- previously none of these had any protection against one
workload starving another on this fixed-capacity cluster, nor automatic
restart on hang.
Values are sized from live `kubectl top pod` baselines gathered this session
(not guessed): e.g. Jellyfin/Immich-server were observed at ~3.1-3.3Gi
resident, so their limits give headroom above that (4Gi) rather than an
arbitrary round number. Used tcpSocket probes instead of httpGet wherever I
wasn't certain of an app's exact health-check path (Immich, Postgres/Redis),
to avoid a wrong path causing false probe failures on a live service.
This is Kubernetes-native and takes effect on next pod restart, but should
still be rolled out watching `kubectl top`/restart counts rather than pushed
and forgotten -- limits set too low can OOMKill under real load.
