利用Docker快速部署Oracle环境
工作中需要频繁使用Oracle环境，但是每次搭建起来比较消耗时间，本想通过虚拟机模板的方式来快速安装oracle vm，但是每次改ip等环境也很耗时，因此想到docker中有没有已经做好的images，这样就能快速获得Oracle环境。

可以看到有很多版本，11g，12c
这里选择获取12c版本
root@- rac1:/home/# docker pull sath89/oracle-12c

使用刚刚下载下来的12g image创建一个container，并运行其上的oracle数据库
docker run -d -p 8080:8080 -p 1521:1521 -v /my/oracle/data:/u01/app/oracle sath89/oracle-12c
[root@-rac1 ~]# docker logs -f ffbeb07058449672c640ddb4e59b8376dae2e3b4dd54142871da7adbc069ee79

到这里Oracle实例就已经启动好了
可以看到创建的container已经在运行中
[root@-rac1 ~]~$ docker ps

---------------------------------------------
接下来就可以快速使用Oracle12C了
