django - 在 Django settings.py for Django-debug-toolbar 的 docker 中获取 NGINX ip 地址

Question

我有一个 dockerized DRF 项目，其中安装了 NGINX。一切正常，除了一件事：

Django debug toolbar需要INTERNAL_IPS在 settings.py 中指定参数。

对于码头工人，我使用这个：

    hostname, _, ips = socket.gethostbyname_ex(socket.gethostname())
    INTERNAL_IPS = [ip[:-1] + "1" for ip in ips]

它也可以正常工作，但不适用于 NGINX，因为 NGINX 使用它自己的 ip 动态（可能？）在内部定义或由 docker 或其他任何东西分配。

我可以从服务器日志中获取此 IP：

172.19.0.8 - - [09/Oct/2020:17:10:40 +0000] "GET /admin/ HTTP/1.0" 200 6166 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.121 Safari/537.36 OPR/71.0.3770.228"

并将其添加到setting.py：

hostname, _, ips = socket.gethostbyname_ex(socket.gethostname())
INTERNAL_IPS = [ip[:-1] + "1" for ip in ips]
INTERNAL_IPS.append('172.18.0.8')

但我希望这个 ip 在不同的机器等上可能会有所不同，所以它不够可靠。

所以这个问题是 - 是否有可能以某种方式在 settings.py 中动态获取 NGINX docker ip 或以某种方式修复 docker-compose？

NGINX的dockerfile：

FROM nginx:1.19.0-alpine

RUN rm /etc/nginx/conf.d/default.conf
COPY nginx.conf /etc/nginx/conf.d

谢谢
