tldr版本：我不知道是什么导致了这个错误。我很肯定这不是行尾，因为我用记事本++手动更改了它们（除非我需要更改的不仅仅是entrypoint.sh，因为这就是我更改的所有行尾）。

原帖如下。

我不知道是什么原因导致了这个错误，当我在命令行中执行docker-compose -f docker-compose-deploy.yml up --build时，我得到了以下输出

搜索***nginx时出现的其他错误示例：[emerg]在/etc/nginx/conf.d/default.conf中的上游“app”中找不到主机：9***联机提示该问题是由于缺少-depends_on：所以我在下面包含了我的docker-compose文件，但是我完全按照教程来做，他的工作很好。我的docker-compose-deploy有它的-depends_on：
我完整的Docker作曲如下

version: '3.7'

services:
  app:
    build:
      context: .
    ports:
      - "8000:8000"
    volumes:
      - ./app:/app
    command: sh -c "python manage.py runserver 0.0.0.0:8000"
    environment:
      - DEBUG=1

我的完整docker-compose-deploy.yml如下

version: '3.7'

  app:
    build:
      context: .
    volumes:
      - static_data:/vol/web

该错误确实提到，它无法找到应用程序，我复制与主要的dockerfile（而不是在代理文件夹）
我的主dockerfile如下。

FROM python:3.8-alpine
ENV PATH="/scripts:${PATH}"
COPY ./requirements.txt /requirements.txt
RUN apk add --update --no-cache --virtual .tmp gcc libc-dev linux-headers
RUN pip install -r /requirements.txt
RUN apk del .tmp
RUN mkdir /app
COPY ./app /app
WORKDIR /app
COPY ./scripts /scripts
RUN chmod +x /scripts/*
RUN mkdir -p /vol/web/media
RUN mkdir -p /vol/web/
RUN adduser -D user
RUN chown -R user:user /vol
RUN chmod -R 755 /vol/web
USER user
CMD ["entrypoint.sh"]

什么可能导致此错误？
你还需要什么信息来解决这个问题？
我在下面这个教程。我在最后https://www.youtube.com/watch?v=nh1ynJGJuT8

更新1（添加额外信息）

我代理/default.conf在下面

server {
  listen 8080;
  location /static {
    alias /vol/static;
  }
  location / {
    uwsgi_pass app:8000;
    include /etc/nginx/uwsgi_params;
  }
}

我的代理/文档文件在下面

FROM nginxinc/nginx-unprivileged:1-alpine

COPY ./default.conf /etc/nginx/conf.d/default.conf
COPY ./uwsgi_params /etc/nginx/uwsgi_params

USER root

RUN mkdir -p /vol/static
RUN chmod 755 /vol/static

USER nginx

更新2

这是我上传到github https://github.com/tgmjack/help的整个项目

更新3

在vscode中编辑行尾似乎不起作用。

更新4

新的dockerfile正在尝试dos 2unix

FROM python:3.8-alpine
ENV PATH="/scripts:${PATH}"
COPY ./requirements.txt /requirements.txt
RUN apk add --update --no-cache --virtual .tmp gcc libc-dev linux-headers dos2unix
RUN pip install -r /requirements.txt
RUN apk del .tmp
RUN mkdir /app
COPY ./app /app
WORKDIR /app
COPY ./scripts /scripts
RUN chmod +x /scripts/*
RUN mkdir -p /vol/web/media
RUN mkdir -p /vol/web/
RUN adduser -D user
RUN chown -R user:user /vol
RUN chmod -R 755 /vol/web
USER user
CMD ["dos2unix", "entrypoint.sh"]

但是我还是得到同样的错误。

更新5

好的，我entrypoint.sh用记事本++手动更改了www.example.com的EOL，但是我仍然得到同样的错误。我需要将此应用到不仅仅是entrypoint.sh?
