1、使用mysql:5.6和 owncloud 镜像，构建一个个人网盘
1）拉取mysql:5.6和owncloud镜像
[root@master ~]# docker pull mysql:5.6

Status: Downloaded newer image for owncloud:latest
docker.io/library/owncloud:latest2）后台运行容器
#mysql
[root@master ~]# docker run -itd --name mysql1 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 mysql:5.6
40402b2c100b13607927946db1c09d2556db03460a33a1dd7a38fa069ea8ab33
#owncloud
[root@master ~]# docker run -itd -p5900:80 --name owncloud1 owncloud:latest
862deb3f6e97585e1c6800062774f73f485b90327a27feee0af0ca769e4734213）通过ip:端口的方式访问owncloud
跟据向导信息完成部署
#上传文件成功即可开始使用
2、安装搭建私有仓库 Harbor
1）首先准备所需包
[root@master ~]# ls
harbor-offline-installer-v2.8.4.tgz docker-compose-linux-x86_642）安装harbor
mv docker-compose-linux-x86_64 /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
#检查docker-compose版本
docker-compose --version
tar xf harbor-offline-installer-v2.8.4.tgz -C /usr/local/
cd /usr/local/
cd harbor/
#备份配置文件
cp harbor.yml.tmpl harbor.yml
#修改配置文件（按需修改）
vim harbor.yml
#安装启动harbor
./install.sh
[+] Running 10/10

3）使用ip地址访问
#因为使用的80端口映射，所以直接访问ip地址
[root@master harbor]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

4）推送镜像
#命令行登录harbor
[root@master ~]# docker login harbor.com.cn
Username: admin

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
1）制作镜像
#创建默认主页
[root@master ~]# mkdir nginx
[root@master ~]# cd nginx/
[root@master nginx]# vim index.html
<h1>docker nginx build successful</h1>
#编写Dockerfile文件（最好放在空目录）
[root@master ~]# mkdir /dockerfile/web -p
[root@master ~]# cd /dockerfile/web/
[root@master web]# vim Dockerfile
#指定使用镜像及版本
FROM centos:7
#标明作者和邮箱
MAINTAINER "test <test.1@139.com>"
#下载wget配置epel源下载nginx
RUN yum install -y wget
RUN wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
RUN yum install -y nginx
#将提前写好的主页替换掉默认的
COPY index.html /usr/share/nginx/html/index.html
#暴露80端口
EXPOSE 80/tcp
#设置开机自启服务
CMD ["nginx", "-g", "daemon off;"]
#构建nginx:v1.1镜像
[root@master nginx]# docker build -t nginx:v1.1 -f /dockerfile/web/Dockerfile .
