ClickHouse Operator

ClickHouse Operator installs the controller, CRDs, and admission webhook Edka uses to provision ClickHouse analytics clusters from the dedicated Databases workspace.

Features available

• ClickHouse custom resources and operator reconciliation
• ClickHouse Keeper coordination support
• cert-manager integration for internal ClickHouse and Keeper certificates
• Prometheus scrape annotations for operator metrics
• Automatic dependency handling when a ClickHouse database is created

How it fits in Edka

The add-on is part of the supported Edka add-ons catalog, but most users reach it through Clusters > Databases. Creating a ClickHouse database queues the operator installation when it is missing, then waits for the operator webhook to be ready before applying the ClickHouse runtime manifests.

ClickHouse databases currently require Kubernetes v1.33 or later in Edka.
