Changelog

All notable changes to this project will be documented in this file.

[Unreleased]

Added

  • Support the label restarter.stackable.tech/ignore on ConfigMaps and Secrets and the annotations restarter.stackable.tech/ignore-configmap.x and restarter.stackable.tech/ignore-secret.x on StatefulSets to exclude ConfigMaps and Secrets from the restarter controller (#410).

Changed

  • Document Helm deployed RBAC permissions and remove unnecessary permissions (#412).
  • Bump stackable-operator to version 0.110.0 (#410).

[26.3.0] - 2026-03-16

[26.3.0-rc1] - 2026-03-16

Added

  • Add conversion webhook (#400).

Changed

  • Bump stackable-operator to 0.107.1, and strum to 0.28 (#401, #404).
  • Gracefully shutdown all concurrent tasks by forwarding the SIGTERM signal (#396).

Fixed

  • BREAKING: Prevent Pod 0 restart by utilizing a mutating webhook. The commons-operator now needs the RBAC permission to create and patch mutatingwebhookconfigurations. The webhook can be disabled using --disable-restarter-mutating-webhook or by setting the DISABLE_RESTARTER_MUTATING_WEBHOOK env variable (#387).

[25.11.0] - 2025-11-07

[25.11.0-rc1] - 2025-11-06

Added

  • Helm: Allow Pod priorityClassName to be configured (#376).
  • Add end-of-support checker (#377).
    • EOS_CHECK_MODE (--eos-check-mode) to set the EoS check mode. Currently, only "offline" is supported.
    • EOS_INTERVAL (--eos-interval) to set the interval in which the operator checks if it is EoS.
    • EOS_DISABLED (--eos-disabled) to disable the EoS checker completely.

Changed

  • Bump stackable-operator to 0.100.1 (#381).
  • Reduce severity of Pod eviction errors. Previously, the operator would produce lot's of Cannot evict pod as it would violate the pod's disruption budget errors. With this fix, the error is reduced to an info instead (#372).
  • Remove workaround for limiting rescheduling delay (#378).

[25.7.0] - 2025-07-23

[25.7.0-rc1] - 2025-07-18

Added

  • Adds new telemetry CLI arguments and environment variables (#349).
    • Use --file-log-max-files (or FILE_LOG_MAX_FILES) to limit the number of log files kept.
    • Use --file-log-rotation-period (or FILE_LOG_ROTATION_PERIOD) to configure the frequency of rotation.
    • Use --console-log-format (or CONSOLE_LOG_FORMAT) to set the format to plain (default) or json.
  • Add RBAC rule to Helm template for automatic cluster domain detection (#365).

Changed

  • Replace stackable-operator initialize_logging with stackable-telemetry Tracing (#338, #344, #349).
    • BREAKING: The console log level was set by COMMONS_OPERATOR_LOG, and is now set by CONSOLE_LOG_LEVEL.
    • BREAKING: The file log level was set by COMMONS_OPERATOR_LOG, and is now set by FILE_LOG_LEVEL.
    • BREAKING: The file log directory was set by COMMONS_OPERATOR_LOG_DIRECTORY, and is now set by FILE_LOG_DIRECTORY (or via --file-log-directory <DIRECTORY>).
    • Replace stackable-operator print_startup_string with tracing::info! with fields.
  • Version CRDs and bump dependencies (#353).
  • Limit rescheduling delay to a maximum of 6 months (#363).
  • BREAKING: Bump stackable-operator to 0.94.0 and update other dependencies (#365).
    • The default Kubernetes cluster domain name is now fetched from the kubelet API unless explicitly configured.
    • This requires operators to have the RBAC permission to get nodes/proxy in the apiGroup "". The helm-chart takes care of this.
    • The CLI argument --kubernetes-node-name or env variable KUBERNETES_NODE_NAME needs to be set. The helm-chart takes care of this.

Fixed

  • Use json file extension for log files (#343).
  • Allow uppercase characters in domain names (#365).

Removed

  • Remove the lastUpdateTime field from the stacklet status (#365).
  • Remove role binding to legacy service accounts (#365).

[25.3.0] - 2025-03-21

Removed

  • BREAKING: Removed the deprecated pod enrichment controller (#321).

Added

  • Aggregate emitted Kubernetes events on the CustomResources (#318).
  • Add the region field to the S3Connection CRD (#331, #335).

Changed

  • Bump stackable-operator to 0.87.0 (#334).
  • Default to OCI for image metadata (#320).

[24.11.1] - 2025-01-09

[24.11.0] - 2024-11-18

Added

  • The operator can now run on Kubernetes clusters using a non-default cluster domain. Use the env var KUBERNETES_CLUSTER_DOMAIN or the operator Helm chart property kubernetesClusterDomain to set a non-default cluster domain (#290).

Changed

  • BREAKING: Bump stackable-operator to 0.78.0 which includes a new AuthenticationClassProvider member for Kerberos. This will need to be considered when validating authentication providers (#285).

Fixed

  • BREAKING: The fields connection and host on S3Connection as well as bucketName on S3Bucketare now mandatory. Previously operators errored out in case these fields where missing (#283).
  • Failing to parse one ZookeeperCluster/ZookeeperZnode should no longer cause the whole operator to stop functioning (#293).
  • The StatefulSet restarter service now only retrieves metadata for ConfigMaps and Secrets, rather than full objects (#293).
