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p_w_picpaths，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

使用刚刚下载下来的12g p_w_picpath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

进入oracle container

[root@-rac1 ~]~$ docker exec -it 9e893d773494 /bin/bash
