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 mysql --env MYSQL_ROOT_PASSWORD=123456 mysql:5.6
d45cc5b95f00692881baafcb9f9b47a0696f5e3a77d0efe95c51faec514ccdc0 
[root@localhost ~]# docker run -itd -p 80:80 --name owncloud --link mysql:mysql owncloud 
0974b4918aa18c963385297908c606813ad1d1f264f6c7f2333e7305aae4c816

在网页中输入本机的IP地址

 二、安装搭建私有仓库 Harbor

#安装docker编排工具docker-compose

[root@localhost ~]# mkdir /harbor
[root@localhost ~]# cd /harbor/
[root@localhost harbor]# curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

[root@localhost harbor]# docker login -u admin -p Harbor12345 1

在网页中输入本机的IP地址加上:8080，用户名admin密码Harbor12345。登录成功页面如下：

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。

（1）基于centos基础镜像；
[root@localhost ~]# docker pull centos:7

（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。
[root@localhost ~]# mkdir centos
[root@localhost ~]# cd centos/
[root@localhost centos]# touch index.html
[root@localhost centos]# echo 'Welcon to Nginx' > index.html 
[root@localhost centos]# vim Dockerfile 
FROM centos:7
MAINTAINER "lsq <lsq@163.com>"
RUN yum install wget -y && cd /etc/yum.repos.d/ && rm -rf ./* && \
    wget -0 /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo && \
    wget -0 /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
RUN yum install -y nginx
COPY index.html /usr/share/nginx/html/
EXPOSE 80
CMD ["/usr/sbin/nginx","-g","daemon off;"]

（6）验证镜像。                                          
[root@localhost centos]#  docker build -t nginx:v1 .
[root@localhost centos]# docker run -p 8090:80 --name ng nginx:v1

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。

要求如下：
（1）基于centos:6基础镜像；
[root@localhost ~]# mkdir lamp
[root@localhost lamp]#docker pull centos:6

（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。
[root@bogon lamp]#wget -O /root/lamp/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-6.10.repo
[root@localhost lamp]# vim Dockerfile
FROM centos:6
MAINTAINER "longsiqi <longsiqi@163.com>"
ADD CentOS-Base.repo /etc/yum.repos.d/
RUN yum install -y httpd mysql mysqL-server php php-mysqL php-gd && \
    yum clean all && yum makecache
EXPOSE 80
EXPOSE 3306
CMD ["sh", "-c", "service httpd start && service mysqld start && tail -f /var/log/httpd/access_log"]
[root@localhost lamp]# docker build -t lamp:v1.1 .
（6）验证镜像。
[root@localhost lamp]# docker run -p 8060:80 --name lp lamp:v1.1
