English ｜ 中文


Docker-compose script for quickly building a ClickHouse cluster environment, based on the official clickhouse/clickhouse-server image, supports custom clickhosue-server versions.

The default component version is as follows ：

  • zookeeper：3.6；
  • clickHouse-server：20.11 ；

Quick Start

git clone https://github.com/Al-assad/clickhouse-cluster-docker.git
docker-compose up

The default created cluster nodes includes 1 zookeeper node, 3 clickhosue-server nodes (3 shards, 1 replica each node).

Connect ClickHouse Cluster from Host Machine

  1. Access via host machine ip:

    clickhouse-server-ch01    127.0.0.1:8124
clickhouse-server-ch02    127.0.0.1:8125
clickhouse-server-ch03    127.0.0.1:8126

  2. Access via docker subnetwork ip:

    If your docker host machine is MacOS, you can access the docker subnetwork directly through the project wenjunxiao/mac-docker-connector.

    clickhouse-server-ch01    172.18.1.5:8123
clickhouse-server-ch02    172.18.1.6:8123
clickhouse-server-ch03    172.18.1.7:8123

Then you can connect the clickhouse-server cluster through DBeaver GUI Tool or clickhosue-client command-line tool. Enjoy it : )

Other Cluster Mode

# single zookeeper node，clickhosue 3 shards and 1 replica
docker-compose -f clickhosue_1zk-3shard-1replica up

# single zookeeper node，clickhosue 3 shards and 3 replicas
docker-compose -f clickhosue_1zk-3shard-3replica up

# 3 zookeeper 3 nodes，clickhosue 3 shards and 1 replica
docker-compose -f clickhosue_3zk-3shard-1replica up

# 3 zookeeper 3 nodes，clickhosue 3 shards and 3 replicas
docker-compose -f clickhosue_3zk-3shard-3replica up

In addition, you can also modify the metrika configuration for the three CH nodes by directly modifying ch-conf/metrika_ch01.xml, ch-conf/metrika_ch02.xml, and ch-conf/metrika_ch03.xml.

Of course, You can customize the CH image version by modifying the environment variable CLICKHOUSE_VERSION.
