从网上整理主要给自己看。步骤比较简单。有好的建议可以提哈~ 若侵权我删掉~
docker pull registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
用 docker images 命令查看镜像
docker images
运行镜像
docker run -d -p 1521:1521 --name oracle registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
进入容器修改账号密码
3.1，检查容器是否运行成功
docker ps
启动oracle
docker start oracle
3.2，进入容器：docker exec -it oracle bash
3.3，切换回root用户
[oracle@a151f9478f94 /]$ exit
exit
[root@localhost ~]#
3.4，编辑环境变量 vi /etc/profile 在文件的末尾添加一下内容
export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_2
export ORACLE_SID=helowin
export PATH=$ORACLE_HOME/bin:$PATH
（注意：按i进入编辑模式，输入上述命令后，按ESC键退出编辑模式，再输入:wq保存退出）
3.6，使得修改生效：
[root@localhost ~]# source /etc/profile
3.7，进入容器（此处的id就是第一个命令下的id），加载一下用户环境变量，进入容器后，自动是oracle用户
[root@localhost ~]# docker ps
