Loaded image: dm8_single:v8.1.2.128_ent_x86_64_ctm_pack4
2.2、导入完成后，可以使用 docker images 查看导入的镜像。结果显示如下：
[root@localhost /]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
dm8_single v8.1.2.128_ent_x86_64_ctm_pack4 ccb727ce9dce 6 months ago 432MB
2.3、启动容器
镜像导入后，使用 docker run 启动容器，启动命令如下：
docker run -d -p 5236:5236 --restart=always --name dm8_01 --privileged=true -e PAGE_SIZE=16 -e LD_LIBRARY_PATH=/opt/dmdbms/bin -e INSTANCE_NAME=dm8_01 -v /data/dm8_01:/opt/dmdbms/data dm8_single:v8.1.2.128_ent_x86_64_ctm_pack4
2.4、查看启动情况
启动完成后，可通过日志检查启动情况，命令如下：
docker logs -f dm8_01
[root@localhost opt]# docker logs -f dm8_01

3、操作数据库
停止数据库命令如下：
docker stop dm8_01
启动数据库命令如下：
docker start dm8_01
重启命令如下：
docker restart dm8_01
4、默认用户名、密码
新版本 Docker 镜像中数据库默认
用户名:SYSDBA
密码:SYSDBA001
4.1、验证
使用DM Manager管理工具连接数据库
