What's new in chart-v0.2.50
This is a metadata-only chart bump: appVersion advances from 0.8.4 to 0.8.5, the default image.tag now resolves to ghcr.io/robintra/perf-sentinel:0.8.5, and the artifacthub.io/images annotation is updated to keep the Artifact Hub display card in lockstep. No chart-level template diff, no values.yaml schema change, no new RBAC, no new optional ConfigMap or Secret, no .perf-sentinel.toml review required to upgrade. The chart-v0.2.49 surface is preserved byte-for-byte.
The 0.8.5 daemon image drains its in-flight streaming window on SIGTERM, so a normal Kubernetes pod termination (a rolling update, a scale-down, a node drain) now flushes the window through detection instead of dropping it. Only an ungraceful kill (SIGKILL after the grace period, OOM) still loses it. The image also builds and runs on Windows now. Full release notes for the daemon at v0.8.5. None of this touches a chart-level template, a daemon HTTP route, a Prometheus metric label set the chart already exposes, or the OTLP listener wire format.
Changed
appVersionbumped from0.8.4to0.8.5, defaultimage.tagnow resolves toghcr.io/robintra/perf-sentinel:0.8.5.artifacthub.io/imagesannotation updated toghcr.io/robintra/perf-sentinel:0.8.5. Runtime image selection is unaffected (templates already resolve to.Chart.AppVersionwhenvalues.yamlimage.tagis empty).- No chart-level config change.
values.yaml, every template, theServiceMonitorrendering, theNetworkPolicyrendering, the optional[daemon.ack]and[daemon.cors]plumbing, and theack-toml-baselinemount are byte-for-byte identical to chart-v0.2.49.
Behavior
- Daemon binary side: graceful drain on SIGTERM. The 0.8.5 image flushes its in-flight streaming window through detection on SIGTERM as well as SIGINT, so a routine pod termination keeps the window in progress instead of dropping it. Only an ungraceful kill (SIGKILL past the grace period, OOM) loses it. To benefit, keep
terminationGracePeriodSecondsabove the configured window duration so the flush completes before the kill. The image also gains a Windows build, with no effect on the Linux runtime the chart deploys. - No daemon runtime change at the chart surface. Every
/api/*route, every/metricsline, the OTLP HTTP and gRPC routes, the detection findings, and the daemon HTTP shapes the chart exposes are unchanged. No upgrade hook, no on-disk migration, the runtime ack store JSONL schema is unchanged and existing acks survive the upgrade.
Install
