}

注意：路径需要在系统上面存在以及对应

2、执行构建镜像命令

[root@localhost nginx]# sudo docker build --rm --tag os7/nginx:centos7 .

执行结果截图：

3、查看镜像是否安装构建成功 docker images

4、创建容器 docker run -i -t -d -p 192.168.32.129:81:80 os7/nginx /bin/bash

注意：192.168.32.129这个IP的话，则需要在/etc/hosts中添加

192.168.32.129     localhost

5、查看容器是否创建成功并启动 docker ps

6、测试是否成功访问 curl http://192.168.32.129:81

会出现这个拒绝连接，那怎么办呢？有办法解决的，我们先进入该容器里面 

7、进入容器 docker exec -i -t small_hodgkin /bin/sh

8、接着在容器里面执行（直接输入即可）

nginx

9、在容器外面执行 curl http://192.168.32.129:81

成功了。

10、再到虚拟机外面通过浏览器访问

到此为止就成功了。
