dockerfile

FROM python:3.10-buster
RUN /usr/local/bin/python -m pip install --upgrade pip -i https://mirrors.aliyun.com/pypi/simple

RUN pip install -i https://mirrors.aliyun.com/pypi/simple -r requirements-prd.txt

docker-compose.yaml

version: "3"
services:
  twitter:
    container_name: twitter
    image: ponponon/twitter
    ports:
      - "8000:8000" # 这里的端口改为和 python manage.py runserver 0.0.0.0:8000  一样的端口才行
    # command: python manage.py runserver 0.0.0.0:8000
    command: ["python","manage.py", "runserver", "0.0.0.0:8000","--noreload"]

使用 docker run --rm -it ponponon/twitter python manage.py runserver 0.0.0.0:8080 一切正常

╰─➤  docker run --rm -it jiuzhang/twitter python manage.py runserver 0.0.0.0:8080

但是使用 docker-compose 就有毛病, 永远卡在 Attaching to

╰─➤  docker-compose up

 ⠿ Network twiter_default  Created                                                                         0.0s

Attaching to twitter

但是在另一个终端使用 docker ps -a 查看，是 running

╰─➤  docker ps -a                                                                                         130 ↵

但是使用 docker logs twitter 却是什么都没有

╰─➤  docker logs twitter
╭─ponponon@MBP13ARM ~/Desktop/code/me/free_workspace/twiter  
╰─➤

回答：

使用关键字: "django docker-compose python manage.py runserver Attaching to" 去谷歌搜索，搜索到下面的词条：

为什么使用 Django+ docker-compose 跑就会一直卡在 Attaching to ?

加上 tty: true 就行

然后，我发现

docker-compose up 的 tty 默认是false

docker run 的时候，如何加上了 -it, 那么 tty 是 true；没有没有加 -it,tty 就是 false
