[root@izbp13xko46hud9vfr5s94z ~]#案例
暴露外部端口
基于docker run -d --name nginx nginx方法启动nginx后，Docker 容器并没有对外暴露访问的端口，即无法通过当前主机外部浏览器器访问nginx。那么该怎么样呢？
语法：
docker run --name nginx -d -p 80:80 nginx
-p 80:80：通过-p来指定Docker容器中nginx实例对外开放的端口。本例中，第一个80端口是对外开放的端口，第二个80端口指对外开放的端口映射到容器里的端口号。示例：
[root@izbp13xko46hud9vfr5s94z ~]# docker run --name nginx -d -p 80:80 nginx

[root@izbp13xko46hud9vfr5s94z ~]#- 通过当前主机外的浏览器访问nginx，如下图：
指定外部的配置文件
语法：
docker run --name nginx -p 80:80 -v /develop/nginx/nginx.conf:/etc/nginx/nginx.conf -v /develop:/develop -d nginx
说明：
-v: 表示挂载一个本机目录或文件到容器里。
-v /develop/nginx/nginx.conf:/etc/nginx/nginx.conf：将/develop/nginx/nginx.conf配置文件挂载到容器中/etc/nginx/nginx.conf这个配置文件中。
-v /develop:/develop：将/develop这个目录挂载到容器里的/develop这个目录里。示例：
[root@izbp13xko46hud9vfr5s94z ~]# docker run --name nginx -p 80:80 -v /develop/nginx/nginx.conf:/etc/nginx/nginx.conf -v /develop:/develop -d nginx

[root@izbp13xko46hud9vfr5s94z ~]#- 图示
注意事项：指定外部配置文件，同时需要指定nginx的首页面，否则会抛出404错误，原因就是因为nginx找不到配置文件中默认的index页面。
本例中，使用/develop/apps/static/index.html替代了容器里的nginx默认的index页面，同时，-v /develop:/develop挂载根目录即可访问子目录。
