要给开发人员搭建 Oracle 测试环境，准备基于 Docker 构建，同时建立一个 Docker 私有仓库，谁需要就让他装一个 Docker，才从这私有仓库 pull 镜像即可。
环境如下：
CentOS 7
docker-ce-18.03.1.ce-1.el7.centos.x86_64
Oracle 12c
安装Docker
# step 1: 安装必要的一些系统工具
yum install -y yum-utils device-mapper-persistent-data lvm2
# Step 2: 添加软件源信息
yum-config-manager --add-repo
# Step 3: 更新并安装Docker-CE
yum makecache && yum -y install docker-ce
# Step 4: 开启Docker服务
systemctl start docker
搜索并下载Oracle镜像
列出收藏数大于100的镜像
[root@Docker ~]# docker search -s 100 oracle
Flag --stars has been deprecated, use --filter=stars=3 instead

# pull第三个镜像
# docker pull sath89/oracle-12c
运行镜像
#-P, 在容器中任何需要的网络端口都映射到主机。即将Docker镜像中的Oracle 1521端口映射到宿主机。
#-v 把docker 容器中某目录的数据 加载到 宿主机的某个目录。即将docker Oracle镜像的数据存储到/data/db 下
docker run -d -p 8080:8080 -p 1521:1521 -v /data/db/:/u01/app/oracle sath89/oracle-12c
启动速度较慢，我们可以去查看日志
# docker logs -f 032d6b2097e8cf3d4dfc3bf173a229bda0a5c8a8a51434299274c652698964a7
