      - "9100:9100"
    volumes:
      - ./conf/docker_related_config.xml:/etc/clickhouse-server/config.d/docker_related_config.xml:rw
      - ./conf/config.xml:/etc/clickhouse-server/config.xml:rw
      - ./conf/users.xml:/etc/clickhouse-server/users.xml:rw

  ch_client:
    image: yandex/clickhouse-client
    entrypoint:
      - /bin/sleep
    command:

1.2 Get the configuration file

• Temporarily start a clickhouse container

[root@liubei clickhouse]# docker run -d --name chtmp yandex/clickhouse-server
[root@liubei clickhouse]# docker ps |grep chtmp
db593c4ad94b        yandex/clickhouse-server                                                 "/entrypoint.sh"         22 seconds ago      Up 21 seconds       8123/tcp, 9000/tcp, 9009/tcp                                                               chtmp

• Create a confdirectory for the configuration file, ensure at least 755 permissions

[root@liubei clickhouse]# mkdir conf
[root@liubei clickhouse]# ll
total 5
drwxr-xr-x 2 root root 4096 Jun 19 13:24 conf

• Copy the configuration file from the container

[root@liubei clickhouse]# cd conf/
[root@liubei conf]# docker cp chtmp:/etc/clickhouse-server/config.d/docker_related_config.xml ./
[root@liubei conf]# docker cp chtmp:/etc/clickhouse-server/config.xml ./
[root@liubei conf]# docker cp chtmp:/etc/clickhouse-server/users.xml ./
-rw-rw-rw- 1 root root 60072 Dec 26  2021 config.xml
-rw-rw-r-- 1 root root   314 Dec 26  2021 docker_related_config.xml
-rw-rw-rw- 1 root root  6248 Dec 26  2021 users.xml

• close temporary container

[root@liubei clickhouse]# docker stop chtmp
chtmp
[root@liubei clickhouse]# docker rm chtmp
chtmp

2. start

clickhouseExecute in the directory :

[root@liubei clickhouse]# docker-compose up -d
Creating network "clickhouse_default" with the default driver
......
Creating clickhouse_ch_server_1 ... done
Creating clickhouse_ch_client_1 ... done
[root@liubei clickhouse]# docker-compose ps
         Name                  Command         State                                 Ports
-------------------------------------------------------------------------------------------------------------------------
clickhouse_ch_client_1   /bin/sleep infinity   Up

3. Test

At this time, we do not have a startup password, just enter the container and log in directly.

• into the container

[root@liubei clickhouse]# docker ps |grep click
