v0.71.0

Update note 1: the new default preStop hook causes a rolling update of all applicable pods on operator upgrade (on Kubernetes >= 1.29). To avoid this, set VM_ENABLE_DEFAULT_PRESTOP_HOOK=false on the operator before upgrading. Once the upgrade is complete, you can re-enable it by removing the override (or setting it to true) to roll out the hook at a time of your choosing. Alternatively, disable the hook per resource by setting spec.preStopSleepSeconds: 0.

• Dependency: vmoperator: Updated default versions for VM apps to v1.145.0 version

• FEATURE: vmoperator: added VM_COMMON_LABELS and VM_COMMON_ANNOTATIONS environment variables to apply common labels/annotations to all Kubernetes resources managed by the operator. These cannot override labels/annotations already set by the operator or via spec.managedMetadata. This also ensures HTTPRoutes and PVCs include ManagedMetadata labels and annotations

• FEATURE: vmoperator: support enableServiceLinks property in all CRs. See #2194.

• FEATURE: vmalertmanagerconfig: add url_file and alert_source_token_file fields to IncidentioConfig, as file-based alternatives to url and alert_source_token. See #2222.

• FEATURE: vmoperator: add status metrics for objects managed by each controller. See #2238.

• FEATURE: vmsingle: added spec.downsampling for structured downsampling configuration and spec.retentionFilters for structured retention filters configuration. Both require an enterprise license.

• FEATURE: vmcluster: added spec.downsampling for structured downsampling configuration (applied to both vmselect and vmstorage) and spec.vmstorage.retentionFilters for structured retention filters configuration. Both require an enterprise license.

• FEATURE: vmoperator: add default preStop lifecycle hook (15s sleep) to applicable component pods to prevent traffic loss during pod termination. Requires Kubernetes >= 1.29. Storage components (VMStorage, VLStorage, VTStorage) are excluded since their clients handle retries. The sleep duration is configurable via spec.preStopSleepSeconds on any CR; set to 0 to disable. See #1834.

• FEATURE: vmanomaly: add missing configuration parameters for vmanomaly config parity: spec.reader.offset and per-query offset, spec.writer.connectionRetryAttempts, spec.server.useReaderConnectionSettings, settings.logger_levels, and the exact/infer_every parameters of the backtesting scheduler. Previously these keys were rejected by strict config parsing.

• FEATURE: vmcluster: add spec.discovery field with enabled, interval and filter properties to configure automatic vmstorage node discovery for vminsert and vmselect. The field can be set globally or overridden per component via spec.vminsert.discovery and spec.vmselect.discovery. This is an enterprise feature and requires a valid license key. See automatic vmstorage discovery.

• BUGFIX: vmoperator: update status currentRevision and currentReplicas for StatefulSet with OnDelete update strategy. See #1242.

• BUGFIX: config-reloader: fix configreloader_last_reload_success_timestamp_seconds metric to report time in seconds instead of milliseconds.

• BUGFIX: vmoperator: enable strict CR spec unmarshalling when creating objects. See #2882.

• BUGFIX: vmoperator: ignore NotFound errors, that may occur during attempt to update status on a missing resource.

• BUGFIX: vmagent, vmanomaly: fix VPA scale subresource lookup failure when spec.shardCount is unset by always reporting at least 1 in status.shards. See #2229.

• BUGFIX: vmagent: fix HPA targeting the underlying Deployment/StatefulSet (pod replicas) instead of the VMAgent CR scale subresource (spec.shardCount); HPA now correctly scales the number of shards. See #2229.

• BUGFIX: vmanomaly: emit the OnlineQuantileModel smoothing parameter under its correct key global_smoothing instead of the unrecognized global_smooth, which vmanomaly silently ignored.

• BUGFIX: vmanomaly: pass the configured TLS CA bundle to the reader, writer and monitoring clients. Previously the CA was mounted as a volume but dropped during config generation, so a tlsConfig with only a CA produced no verify_tls reference to it; insecureSkipVerify is now also propagated correctly.

• BUGFIX: vmanomaly: serialize the tz timezone of spec.reader, of each query, and of the periodic scheduler as a string. It was serialized to {} and could not be parsed from a string, so any configuration that set tz failed to reconcile.

• BUGFIX: vmanomaly: fix the AutoTunedModel trials parameter spelling n_trials, previously it was rendered as n_trails which was silently ignored by vmanomaly.

• BUGFIX: vmanomaly: preserve an explicit 0.0 for the anomaly_score_outside_data_range parameter (both settings and model level), which was dropped by the underlying float field and silently reverted to the vmanomaly default.

• BUGFIX: vmanomaly: validate online models' decay against the (0, 1] range while still allowing it to be omitted.

• BUGFIX: vmanomaly: accept a float value (for example 0.01) for the isolation forest contamination parameter in addition to the string auto.

• BUGFIX: vmanomaly: omit the OnlineQuantileModel min_subseason key when it is unset instead of emitting an empty string.

• BUGFIX: vmanomaly: remove the artificial upper bound on spec.server.maxConcurrentTasks; vmanomaly accepts any positive integer.
