Docker可以在Linux盒子上工作，但不能在Windows盒子上工作

Question

我的dockers在Linux盒子上工作得很好。在我的windows笔记本电脑上使用类似的docker、docker compose和配置文件，它们没有。

当我浏览到127.0.0.1:1337时，我得到一个502坏网关错误。从docker日志pbnginx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:

FROM python:3.6
ENV PYTHONUNBUFFERED 1
ENV PYTHONDONTWRITEBYTECODE 1
COPY ./requirements.txt /requirements.txt
RUN pip install -r /requirements.txt
RUN mkdir /code
WORKDIR /code
ADD . /code/
RUN chmod -R 755 /code
RUN useradd -m user
RUN chmod 777 /home/user
USER user
ENV PORT 7000
EXPOSE 7000
CMD ["gunicorn", "PB_Django.wsgi:application", "--config", "docker/pb_django/gunicorn.conf", "--keep-alive", "600"]

我的码头组合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/;
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/ {
}
}

我的gunicorn.conf是：

bind = "0.0.0.0:7000"
timeout = 10000

docker ps-a显示：

Answer 1

查看"Quickstart:Compe和Django"；，尝试，为了测试，注意：

在某些平台(Windows 10(上，您可能需要在settings.py中编辑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 = ['*']

此值对于生产使用是不安全的
有关详细信息，请参阅Django文档。

如果您看到与"；将Django与Postgres、Gunicorn和Nginx对接；。

Answer 2

尽管docker inspect pbdjango报告OOMKIlled为false(由于内存不足而被杀死(，我还是将docker桌面上的内存从2 GB增加到了8 GB，我的应用程序在上述配置下正常工作。感谢所有花时间看这篇文章的人。
