基于OpenJDK部署clickhouse-local镜像的快捷方法

---

摘要

前期搭建了一套基于OpenJDK的Clickhouse的服务端的镜像
可以简单使用dbeaver进行连接与使用. 

后来发现需求与自己理解的不一样.
更加需要的是一套使用clickhouse-local 进行文件解析处理的功能.
服务可以不运行. 

所以之前的思路需要改善一下.

部署方式

clickhouse 有多种安装方式.
可以使用在线安装, tar包离线安装,rpm包安装等等方式. 

本次简单起见还是仿照之前 在线 sh安装的一部分来进行. 

获取对应的二进制进行容器内安装,然后清理部分文件.
仅保留clickhouse-local等指令的方式.

说明

只留客户端时不需要 不需要部分配置文件.
不然会在执行命令是报错如下:
会打印出来很多日志.

在同事的提醒下发现删除部分呢配置文件就可以简单实现不打印日志的方法了

1024

1024 就是需要查询出来的结构

下载方式

https://mirrors.aliyun.com/clickhouse/tgz/lts/

获取到tar包,解压缩出来一个 clickhouse的文件就可以了.

---

打包方式

文件主要如下 :

[root@tidb01 clickhouse]# tree -L 1
.
├── clickhouse
└── dockerfile

---

dockerfile

FROM  192.168.xxx.xx:5000/library/openjdk:8
COPY clickhouse /usr/bin/
WORKDIR /etc/clickhouse-server
RUN  /usr/bin/clickhouse install
RUN rm -rf /etc/clickhouse-server/*

---

生成镜像与验证

docker build . -t clickhouse:v1.0
验证
docker run -it clickhouse:v1.0 bash
执行命令:
root@d5dc9984a419:/etc/clickhouse-server# clickhouse-local -q "select 1"
