问题是什么？

我有一个 Dockerfile、docker-compose.yml 和一个 run.sh 脚本，用许多配置来运行我的 django 服务器，一切都测试好了，但是最终服务器无法在 run.sh bash 脚本中的 python3 manage.py runserver 127.0.0.1:80 命令下运行。

我到处搜索了，但仍然找不到任何解决方案。如果有人能指导我找到问题所在，我将不胜感激，因为我在使用 docker-compose 运行一个简单的 django 服务器的过程中已经浪费了两天时间。

包含的文件

这是我的 docker-compose.yml 文件：

version: "3.9"
services:
  backend:
    build:
      context: .
      dockerfile: backend.Dockerfile
    restart: always
    image: backend:latest
    container_name: backend
    networks: 
      - net
    dns: backend
    volumes:
      - /project/backup:/project/backup --name backup
volumes:
  backup:
    name:
      "backup"
networks:
  net:
    name: net
    driver: bridge

这是我的 Dockerfile，你只需要读取最后的 CMD 行，因为它上面的其他命令都能正常工作：

# This is the only latest version of alpine that actually works with uwsgi

# for mysql and postgres

    && apk add --update --no-cache --virtual build-deps \

    && echo && echo \

    && sleep 60 \

    && echo "StrictHostKeyChecking accept-new" >> /etc/ssh/ssh_config \
    && git clone "My-Super-Private-Git-Repository :)" /project/

COPY .env .env
COPY run.sh run.sh
RUN chmod +x run.sh
EXPOSE 1080 80:80 9418
# Here my problem starts
CMD ["./run.sh"]

这是运行迁移，然后启动服务器的 run.sh 脚本：

#!/bin/bash
cd /project
echo "(requirements)"
pip3 install -r requirements.txt
echo "(makemigrations)"
python3 manage.py makemigrations users anjoman notification
echo "(migrate)"
python3 manage.py migrate
echo "(runserver)"
# Script stops right when reading this command
python3 manage.py runserver 127.0.0.1:80

总结

正如您在日志最后一行所看到的，当尝试执行 python3 manage.py runserver 127.0.0.1:80 命令时，run.sh 内部的命令根本没有运行，也没有给我任何关于它发生了什么的迹象。

我需要的只是知道刚刚发生了什么，以及如何修复它。

同时感谢您对需要知道的事情进行提醒。

可能已经运行了python3 manage.py runserver 127.0.0.1:80，只是日志没有被刷新。

一种选项是在docker-compose.yaml中添加PYTHONUNBUFFERED=1以让python不缓存输出：

services:
  backend:
    environment:
      - PYTHONUNBUFFERED=1
    build:
      context: .
      dockerfile: backend.Dockerfile

或者在docker-compose.yaml中添加tty: true以将输出更改为按行缓冲：

services:
  backend:
    tty: true

然后，检查日志以查看是否有任何输出可以帮助您进行调试。
