docker for mac/windows 里的 nginx 如何获取到访客的真实 IP？

[fuxkcsdn]

docker 版本: Version 17.03.1-ce-mac12 (17661)

nginx 镜像版本 latest(1.13.1)

宿主机内网 IP：192.168.1.101

手机内网 IP：192.168.1.103

> docker run -d -p 8080:80 --name httpd nginx:latest

在宿主机上访问 http://192.168.1.101:8080

在手机上访问 http://192.168.1.101:8080

> docker logs httpd
172.17.0.1 - - [23/Jun/2017:14:36:00 +0000] "GET / HTTP/1.1" 200 612 "-" "curl/7.51.0" "-"
172.17.0.1 - - [23/Jun/2017:14:36:41 +0000] "GET / HTTP/1.1" 200 612 "-" "Mozilla/5.0 ..." "-"

同样的命令在 linux 宿主机上不会出现这问题

楼主是用的 docker on Windows 10 吗

我之前装这个后, 貌似主机的 tracert 就无法工作了. 麻烦楼主在主机上试试 tracert

```
tracert www.baidu.com

```

docker 做了 SNAT，最简单的做法是 docker run -d -p 8080:80 --net host --name httpd nginx:latest

@neilp 安装的是 docker for windows，主机系统是 windows 10，刚测试 主机的 tracert 是正常的

@htfy96 用 --net host 后访问不了呢...

哈喽, 这个问题现在有解决的方法了么

MAC- 只能获取容器的 IP. 但是 Linux 上可以获取到客户端的真实 IP [关于问题相关的资料]( http://www.majianwei.com/archives/7909)
