Description

Deploys a ClickHouse analytics database inside your cluster using the official ClickHouse operator. Good for event logs, time-series data, and anything where you need fast aggregations over millions of rows.

Installs two services: the ClickHouse operator (in clickhouse-operator namespace) and a single-shard ClickHouse cluster with Keeper for coordination (in clickhouse namespace). Other installations connect over HTTP on port 8123 or native TCP on port 9000 using the httpHost and nativeHost outputs. Authentication uses the default user with a password stored in a Kubernetes secret (output: passwordSecretName).

Enable "Expose Dashboard" to publish the ClickHouse Play UI at <installation-name>.<environment-domain> with auto-provisioned TLS.
