四.Dockerfile快速搭建自己专属的LAMP环境，生成镜像lamp:v1.1，并推送到私有仓库，以下为具体要求：
一.使用mysql:5.6和owncloud镜像，构建一个个人网盘
[root@localhost ~]# docker pull mysql:5.6
[root@localhost ~]# docker pull owncloud
[root@localhost ~]# docker run -itd --name mydb --env MYSQL_ROOT_PASSWORD=SLB123 mysql:5.6
[root@localhost ~]# docker run -itd --name myweb -p 80:80 --link mydb:mydb owncloud使用IP进行访问，用admin+运行容器时设置的密码登录
二.安装搭建私有仓库Harbor
[root@localhost ~]# cd /usr/local/
[root@localhost local]# rz -E

三.编写Dockerfile制作Web应用系统nginx镜像，生成镜像nginx:v1.1，并推送其到私有仓库，以下为具体要求：
（1）基于centos基础镜像
（2）指定作者信息
（3）安装nginx服务，将提供的dest目录（提供默认主页index.html）传到镜像内，并将dest目录内的前端文件复制到nginx的工作目录
（4）暴露80端口
（5）设置服务自启动
（6）验证镜像
[root@harborslb centos]# vim /etc/docker/daemon.json
{
"registry-mirrors":["https://docker.mirrors.ustc.edu.cn"],
"insecure-registries":["192.168.2.190:8080"]
}

[root@localhost centos]# vim Dockerfile
