Question

我的docker在Linux机器上工作得很好。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，出现502 Bad Gateway错误。从泊坞窗日志pbnginx我得到：

typedef union unionTest
{
    struct notAnonymous
    { uint32_t          nField1:5
    ; uint32_t          nField2:4
    ; uint32_t          nField3:23
    ;} notAnonymous
; uint32_t              nRaw                            ///< Raw data
;} unionTest;

// Using const saves RAM, one of the reason to switch to C++
const unionTest myCppUnion2 = {.notAnonymous.nField1 = 1, .notAnonymous.nField2 = 2, .notAnonymous.nField3 = 3 }; // expected primary-expression before '.' error
const unionTest myCppUnion3 = { .notAnonymous = { .nField1 = 1, .nField2 = 2, .nField3 = 3 } }; // Compiles

我的Dockerfile：

我的docker-compose.yml

CMD ["gunicorn", "PB_Django.wsgi:application", "--config", "docker/pb_django/gunicorn.conf", "--keep-alive", "600"]

我的nginx Dockerfile：

version: "3.8"

services:
  web:
      build:
          context: ../..
          dockerfile: docker/pb_django/Dockerfile

      container_name: pbdjango
      expose:

      depends_on:

我的nginx.conf文件：

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gunicorn.conf是：

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

server {
    root /;

    listen 80;

    location / {
        proxy_pass http://pb_django/;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_redirect off;
        proxy_read_timeout 10m;
        proxy_connect_timeout 10m;
        client_max_body_size 700m;
    }

    location /static/ {
    }
}

docker ps -a显示：

bind = "0.0.0.0:7000"
timeout = 10000

docker network inspect cieenetwork显示：

Answer 1

看“ Quickstart: Compose and Django”，尝试测试该笔记：

在某些平台（Windows 10）上，您可能需要在settings.py内编辑ALLOWED_HOSTS并将Docker主机名或IP地址添加到列表中。
出于演示目的，您可以将值设置为：
ALLOWED_HOSTS = ['*']
此值对生产用途不安全
有关更多信息，请参见Django documentation。

还要检查是否与“ Dockerizing Django with Postgres, Gunicorn, and Nginx”有任何区别。

Answer 2

尽管，docker inspect pbdjango报告说OOMKIlled为false（由于内存不足而杀死），我在docker桌面上将内存从2 GB增加到8 GB，并且我的应用程序可以在上述配置下正常工作。感谢所有花时间阅读这篇文章的人。
