环境
一个Docker Hub账号。一台Linux 主机。
目标
操作系统Oracle Linux 7，运行容器数据库，数据库为单实例企业版，版本12.2.0.1，实例名为ORCLCDB，带一个可插拔数据库orclpdb1。
创建Linux操作系统
如果用本地的Windows笔记本，在Vagrantfile中将内存改为4096，然后创建虚机（Oracle Linux 7）。耗时6分59秒。
PS E:\DB\vagrant-boxes\OracleLinux\7> Measure-Command { vagrant up | Out-Default}
本例我使用的是OCI公有云上的主机，因为下载快些。
安装Docker
安装Docker，耗时1m9.076s：
sudo yum install -y yum-utils
sudo yum-config-manager --enable ol7_addons
sudo yum install -y docker-engine
sudo systemctl start docker
sudo systemctl enable docker
确认：
$ sudo docker version

用户vagrant加入到docker组，如果是OCI公有云，改为opc用户：
$ sudo usermod -aG docker vagrant
$ id vagrant
uid=1000(vagrant) gid=1000(vagrant) groups=1000(vagrant),10(wheel),993(docker)
Pull Docker Image
访问Docker Hub中Oracle专属页面。
$ docker login
$ docker pull store/oracle/database-enterprise:12.2.0.1 或者
$ docker pull store/oracle/database-enterprise:12.2.0.1-slim
非slim版3.44GB，耗时5m38.318s（另一次仅用了2分钟）；slim版小一些，为2.08GB，耗时2m51.174s。
slim版没有以下功能：
Analytics, Oracle R, Oracle Label Security, Oracle Text, Oracle Application Express and Oracle DataVault
查看image:
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

store/oracle/database-enterprise 12.2.0.1-slim 27c9559d36ec 2 years ago 2.08GB
创建容器数据库
docker run -d -it --name odbee12201 -P store/oracle/database-enterprise:12.2.0.1
数据库就绪还需要一些时间，请观察日志，等待信息Done ! The database is ready for use .出现，此步骤用了190秒：
