• 安装完成并启动后测试：

[root@0c27bcf9bd58 ~]# echo "woaini" > /usr/local/nginx/html/test.html
[root@0c27bcf9bd58 ~]# curl localhost/test.html
woaini
[root@0c27bcf9bd58 ~]#

• 通估镜像生成容器实例

[root@bogon ~]# docker ps -a

说明基于 docker 的 nginx 服务器搭建成功

• 查看容器的 ip

[root@f8f6ba65fdea ~]# ifconfig

• 保存镜像到本地

[root@bogon ~]# docker save -o docker.io-centos-nginx-image.tar  docker.io/centos:nginx 
[root@bogon ~]# ll -h

-rw-------. 1 root root 651M 3月  28 16:33 docker.io-centos-nginx-image.tar
[root@bogon ~]#

• 端口映射：

[root@bogon ~]# docker run -d -p 80:80 docker.io/centos:nginx
