django - docker-compose up --build 声明一个错误，但是在我使用 docker-compose up 后它可以工作 什么是给我错误的问题

问题描述

我在下面添加了代码，希望它清晰准确

Dockerfile：

FROM python:3.8.5-alpine

RUN pip install --upgrade pip

COPY ./requirements.txt .
RUN pip install -r requirements.txt

COPY ./ddc /app

WORKDIR /app

COPY ./entrypoint.sh /
ENTRYPOINT ["sh", "/entrypoint.sh"]

码头工人-compose.yml

version: '3.7'

services:
  django_gunicorn:
    volumes:
      - static:/static
    env_file:
      - .env
    build:
      context: .
    ports:
      - "8000:8000"
  
  nginx:
    build: ./nginx
    volumes:
      - static:/static
    ports:
      - "80:80"
    depends_on:
      - django_gunicorn

volumes:
  static:

入口点.sh

#!/bin/sh

python manage.py migrate --no-input
python manage.py collectstatic --no-input

gunicorn ddc.wsgi:application --bind 0.0.0.0:8000

首先我使用 docker-compose up --build

这就是我得到的：

之后我只使用 docker-compose up

并且系统按预期工作。这个错误是什么意思，我该如何避免它。我使用最新的 docker 和 compose，它们是：

docker:Docker version 19.03.13, build cd8016b6bc
docker-compose version 1.29.2, build 5becea4c

解决方案

在我将安装从 ubuntu snap 更改为

https://docs.docker.com/compose/install/
