Add startupProbe to give Jellyfin sufficient time to start, especially with large media libraries or slow storage. This prevents Kubernetes from killing the pod during initial startup phase. Changes: - Add startupProbe configuration in values.yaml with sensible defaults - failureThreshold: 30 (allows up to 5 minutes for startup) - periodSeconds: 10 - Uses tcpSocket check on http port - Update deployment.yaml to include startupProbe from values - Bump chart version 2.5.0 -> 2.5.1 - Add changelog annotation for Artifact Hub Benefits: - Prevents pod restarts during slow initial startup (large media libraries) - Liveness and readiness probes remain responsive after successful startup - Fully configurable and can be disabled by setting startupProbe: null - No breaking changes, backward compatible The startup probe gives Jellyfin up to 5 minutes (30 attempts * 10 seconds) to complete initialization. After the first success, liveness and readiness probes take over with their normal timing. Co-Authored-By: Claude <noreply@anthropic.com> Signed-off-by: Aleksei Sviridkin <f@lex.la>
