使用 dockerFile 创建镜像

FROM nginx
RUN echo '<h1>Hello, Docker!</h1>' > /usr/share/nginx/html/index.html

容器的使用

构建 yat

下载源码

git clone https://gitee.com/opengauss/Yat.git

构建 yat

cd Yat/yat-master
chmod +x gradlew
./gradlew pack

cd pkg
chmod +x install
./install -F

根据源码中的 dockerFile 构建 dockerImage

使用 yat 测试 测试 shardingSphere proxy

利用构建的 yat image 运行相关测试 需要挂在到对应目录

docker run --name yat0 -i -t -v /Users/chenchuxin/Documents/GitHub/Yat/openGaussBase:/root/openGaussBase -w /root/openGaussBase --entrypoint=bash --privileged=true yat-v1

修改 yat 项目 openGaussBase/conf 下的 configure.yml 文件

mac 开发环境启动 galaxysql

https://hub.docker.com/r/polardbx/polardb-x

docker pull polardbx/polardb-x

docker run -d --name some-dn-and-gms --env mode=dev -p 4886:4886 -p 32886:32886 polardbx/polardb-x

docker exec -it 41d8a027 bash
mysql -h127.0.0.1 -P4886 -uroot -padmin -D polardbx_meta_db_polardbx -e "select passwd_enc from storage_info where inst_kind=2"

获取密码后修改 server.properties

注释掉 CobarServer.java 中 tryStartCdcManager(); 代码

Step 1: 克隆项目

Step 2: 添加新的远程仓库 为了修改他人 Fork 的仓库，你需要将其添加到自己的远程仓库列表中

$ git remote add sirmin https://github.com/SirMin/shardingsphere.git

现在，当你执行 git remote -v 指令时，就可以看到他人 Fork 的仓库，出现在你的远程仓库列表中：

% git remote -v
origin	https://github.com/tuichenchuxin/shardingsphere.git (fetch)
origin	https://github.com/tuichenchuxin/shardingsphere.git (push)
sirmin	https://github.com/SirMin/shardingsphere.git (fetch)
sirmin	https://github.com/SirMin/shardingsphere.git (push)
upstream	https://github.com/apache/shardingsphere.git (fetch)
upstream	https://github.com/apache/shardingsphere.git (push)

Step 3: 拉取新的远程仓库

docker pull registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

docker run --privileged --restart=always --name oracle_11g -p 1521:1521 -d registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

docker exec -it 容器ID /bin/bash

source /home/oracle/.bash_profile

sqlplus nologconnect as sysdba

create user oracle identified by oracle#123;
alter user system identified by system;
alter user system identified by 123456;
grant connect,resource,dba to oracle;
