- Implement InheritClusterReconcileFrom method to inherit reconcile settings from ClickHouseKeeperInstallation. - Add prepareStsReconcileOptsWaitSection to set StatefulSet reconcile options based on readiness and startup probes. - Normalize reconcile host settings in the normalizer. - Update HostObjectsPoller to safely delete ready marks only if readyMarkDeleter is initialized. - Introduce new replacer for CHK clusters in the engine. - Extend namer functionality to handle CHK clusters.

Thank you, @perosb. The next operator release (0.26) will be focused almost solely on improving Keeper support. |

This pull request introduces enhancements to the ClickHouse Keeper (CHK) controller logic, focusing on better inheritance and normalization of reconcile settings, improved handling of StatefulSet reconciliation, and extended macro/namer support for CHK clusters. The changes improve the maintainability and configurability of cluster reconciliation, ensuring CHK clusters inherit correct settings and are properly identified throughout the codebase.
Reconcile settings inheritance and normalization:
Cluster.InheritClusterReconcileFromto allow CHK clusters to inherit reconcile settings from the parent CR, ensuring consistent runtime and host reconciliation behavior. [1] [2]normalizeReconcileHost), improving the reliability of host-specific settings.StatefulSet reconciliation improvements:
prepareStsReconcileOptsWaitSection, enabling conditional setting ofWaitUntilStartedandWaitUntilReadyoptions for StatefulSet reconciliation based on probe readiness, with appropriate logging.Macro and namer support for CHK clusters:
*apiChk.Clusterobjects, supporting namespace, CR name, and cluster name resolution for CHK clusters. [1] [2] [3] [4] [5] [6] [7]Fixes #1796
