（1） 实现一个自定义的web容器服务
- 推荐apache或nginx，要求标明镜像作者信息，安装必要的工具以方便维护；设定你自己的web存放目录，安全起见，请将默认的监听端口80更改为你自定义的端口，并且声明暴露的端口，容器启动时，能直接进入web代码的存放目录。
1.拉取镜像
2.通过镜像打开容器
3.查看初始端口和文件存储位置
4.编写dockerfile并编写相关文件用于更改端口以及所指向的html文件
mkdir Dockerfile
gedit lhw.html
gedit new.conf
5.创建更改后的镜像并验证更改后的情况
查看端口号
进入网址查看
（2） 实现一个自定义的数据库容器服务
- 可选择Mysql，Mariadb等，要求标明镜像作者信息，为了方便维护，需要能够查看容器内的配置信息，包括但不限于网络、应用配置文件等。在环境变量中设置好数据库的root密码且不允许空密码登录，创建一个测试数据库，指定用户名和密码。
1.拉取mysql：5.7镜像
这一步建议先自己弄下阿里云镜像加速器，不然拉取过程会是漫长的等待还可能没有结果。。。说多了都是泪。
2.编写相关文件
mkdir mysql
gedit Dockerfile
gedit privileges.sql
gedit schema.sql
gedit setup.sh
3.创建镜像
运行容器
查看容器id
4.连接mysql并查看表
5.查看配置信息
