2、下载镜像

[root@v1 ~]# docker pull enmotech/opengauss
Using default tag: latest
latest: Pulling from enmotech/opengauss
Digest: sha256:d5a3e38fa2553a44e7fa1cd5cad0b4f0845a679858764067d7b0052a228578a0
Status: Image is up to date for enmotech/opengauss:latest

3、启动镜像
docker run --name opengauss --privileged=true -d -e GS_PASSWORD=Enmo@123 enmotech/opengauss:latest

openGauss的密码有复杂度要求，需要：密码长度8个字符及以上，必须同时包含英文字母大小写，数字，以及特殊符号**

`GS_NODENAME`

指定数据库节点名称 默认为gaussdb

 `GS_USERNAME`

指定数据库连接用户名 默认为gaussdb

 `GS_PORT`

指定数据库端口，默认为5432。

4、查看
[root@v1 ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

5、进入

[root@v1 ~]# docker exec -it 59cdbac115da   bash
root@59cdbac115da:/#

6、申请ecs
6.1 体验ecs
https://developer.aliyun.com/adc/scenario/410e5b6a852f4b4b88bf74bf4c197a57?taskCode=tiyan010&recordId=2450769

6.2申请一个免费一个月的ecs，安装docker，上面部署数据库环境，进行测试。

7、查看docker信息，获取opengauss目录

[root@v1 ~]# docker history enmotech/opengauss:latest
