ClickHouse

Create itCopy Anchor Link

In your project, choose Create, then ClickHouse from the templates. Raseef creates the service with the settings below, generates its secrets and deploys it. Its data lives on its own volume.

Connect from your appCopy Anchor Link

ClickHouse is a private service: it has no public address. Other services in the same environment reach it on its private address and port, which Raseef offers as variables you can reference.

Add a variable to your app that references the CLICKHOUSE_URL of this service. If you named the service clickhouse:

CLICKHOUSE_URL=${{ clickhouse.CLICKHOUSE_URL }}

At deploy time the reference becomes a full connection string:

http://raseef:<CLICKHOUSE_PASSWORD>@<private address>:8123/?database=raseef

See Variables for how references work.

Generated once, when the service is created, and stored encrypted:

Set by the template:

Every variable of a template service is managed by Raseef and cannot be edited. The workspace owner can reveal the secrets from the service panel; each reveal is recorded in the audit log.

Data and backupsCopy Anchor Link

The data directory /var/lib/clickhouse is a persistent volume: it survives restarts and deploys. A service with a volume runs a single replica, and a deploy stops the old replica before starting the new one, so expect a short interruption. See Volumes for sizes and backups.

VersionCopy Anchor Link

The service runs clickhouse/clickhouse-server:25.8, pinned by digest when the service is created and kept on that exact image afterwards. Template catalog version 2026-10-19.1.
