ClickHouse Server Docker Image

What is ClickHouse?

ClickHouse is an open-source column-oriented database management system that allows generating analytical data reports in real time.

ClickHouse manages extremely large volumes of data in a stable and sustainable manner. It currently powers Yandex.Metrica, worlds second largest web analytics platform, with over 13 trillion database records and over 20 billion events a day, generating customized reports on-the-fly, directly from non-aggregated data. This system was successfully implemented at CERNs LHCb experiment to store and process metadata on 10bn events with over 1000 attributes per event registered in 2011.

More information about ClickHouse client.

Configuration

Container exposes 8123 port for HTTP interface and 9000 port for native client.

ClickHouse configuration represented with a file "config.xml" (documentation)

start server instance with custom configuration

$ docker run -d --name some-clickhouse-server --ulimit nofile=262144:262144 -v /path/to/your/config.xml:/etc/clickhouse-server/config.xml yandex/clickhouse-server

Start server as custom user

# $(pwd)/data/clickhouse should exist and be owned by current user
$ docker run --rm --user ${UID}:${GID} --name some-clickhouse-server --ulimit nofile=262144:262144 -v "$(pwd)/data/clickhouse:/var/log/clickhouse-server" -v "$(pwd)/data/clickhouse:/var/lib/clickhouse" yandex/clickhouse-server

When you use the image with mounting local directories inside you probably would like to not mess your directory tree with files owner and permissions. Then you could use --user argument. In this case, you should mount every necessary directory (/var/lib/clickhouse and /var/log/clickhouse-server) inside the container. Otherwise, image will complain and not start.

How to extend this image

If you would like to do additional initialization in an image derived from this one, add one or more *.sql, *.sql.gz, or *.sh scripts under /docker-entrypoint-initdb.d. After the entrypoint calls initdb it will run any *.sql files, run any executable *.sh scripts, and source any non-executable *.sh scripts found in that directory to do further initialization before starting the service. Also you can provide environment variables CLICKHOUSE_USER & CLICKHOUSE_PASSWORD that will be used for clickhouse-client during initialization.

For example, to add an additional user and database, add the following to /docker-entrypoint-initdb.d/init-db.sh:

#!/bin/bash
set -e

clickhouse client -n <<-EOSQL
	CREATE DATABASE docker;
	CREATE TABLE docker.docker (x Int32) ENGINE = Log;
EOSQL
