1、使用mysql:5.6和 owncloud 镜像，构建一个个人网盘。
[root@node1 ~]# docker pull mysql:5.6
[root@node1 ~]# docker pull owncloud
[root@node1 ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

2、安装搭建私有仓库 Harbor
1、安装docker编排工具docker-compose
[root@node1 ~]# curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
[root@node1 ~]# chmod +x /usr/local/bin/docker-compose
[root@node1 ~]# docker-compose version
Docker Compose version v2.20.3
2、下载Harbor安装包
[root@node1 ~]# wget -c https://github.com/goharbor/harbor/releases/download/v2.4.1/harbor-offline-installer-v2.4.1.tgz
[root@node1 ~]# tar xf harbor-offline-installer-v2.8.4.tgz -C /usr/local/
#配置Harbor服务
[root@node1 ~]# cd /usr/local/harbor/
[root@node1 harbor]# cp harbor.yml.tmpl harbor.yml
[root@node1 harbor]# vim harbor.yml
hostname: www.openlab.cn
#https: 注释# https port for harbor, default is 443

3、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。具体要求如下：
（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@node1 ~]# mkdir nginx
[root@node1 ~]# cd nginx/
[root@node1 nginx]# mkdir dest
[root@node1 nginx]# echo "nginx test page" > dest/index.html
[root@node1 nginx]# vim Dockerfile

4、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。具体要求如下：
（1）基于centos:7基础镜像；
（2）指定作者信息；
（3）安装httpd、mysql、mysql-server、php、php-mysql、php-gd；
（4）暴露80和3306端口；
（5）设置服务自启动。
（6）验证镜像。
[root@node1 ~]# mkdir lamp
[root@node1 ~]# cd lamp
[root@node1 lamp]# vim Dockerfile
