ClickHouse CLI

The ClickHouse CLI (clickhousectl) is a unified command-line tool for managing ClickHouse Cloud resources and local development with ClickHouse. It also manages ClickHouse Cloud Postgres services.

Installation

curl https://clickhouse.com/cli | sh

A chctl alias is also created automatically for convenience.

Cloud management

Authenticate with ClickHouse Cloud and manage your services directly from the command line.

Authentication

clickhousectl cloud auth

This prompts for your API key and secret, and saves them to .clickhouse/credentials.json (project-local, git-ignored).

You can also use environment variables:

export CLICKHOUSE_CLOUD_API_KEY=your-key
export CLICKHOUSE_CLOUD_API_SECRET=your-secret
