Dockers 在 Linux box 上工作，但不在 Windows box 上工作

Question

我的 docker 在 Linux 盒子上效果很好。在我的 windows 笔记本电脑上使用类似的 docker、docker-compose 和配置文件，但它们没有。

当我浏览到 127.0.0.1:1337 时收到 502 Bad Gateway 错误。从 docker 日志 pbginx 我得到：

172.20.0.1 - - [08/Oct/2020:20:32:04 +0000] "GET / HTTP/1.1" 499 0 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.121 Safari/537.36" "-"

我的 Dockerfile：

我的docker-compose.yml

我的 nginx Dockerfile：

FROM nginx:alpine

RUN rm -f /etc/nginx/conf.d/default.conf
COPY nginx.conf /etc/nginx/conf.d/default.conf
COPY static_cdn /static

我的 nginx.conf 文件：

upstream pb_django {
    server web:7000 fail_timeout=0;
}

server {
    root /;

    listen 80;

    location / {
        proxy_pass http://pb_django/;

        client_max_body_size 700m;
    }

    location /static/ {
    }
}

我的gunicorn.conf是：

bind = "0.0.0.0:7000"
timeout = 10000

docker ps -a 显示：

Answer 1

查看“Quickstart: Compose and Django”，尝试进行测试，注释：

On certain platforms (Windows 10), you might need to edit ALLOWED_HOSTS inside settings.py and add your Docker host name or IP address to the list.
For demo purposes, you can set the value to:
ALLOWED_HOSTS = ['*']
This value is not safe for production usage
Refer to the Django documentation for more information.

如果您发现与“Dockerizing Django with Postgres, Gunicorn, and Nginx”有任何不同，请同时检查。

Answer 2

尽管 docker inspect pbdjango 报告 OOMKIlled 是错误的（由于内存不足而被杀死），我在 docker 桌面上将内存从 2 GB 增加到 8 GB，并且我的应用程序与以上配置。感谢所有花时间看这篇文章的人 post。
