在Docker中启动后如何运行Django manage.py命令（Django-background-tasks）？ [英] How to run a Django manage.py command (Django-background-tasks) after startup in Docker?

问题描述

我有一个正在使用Docker的Django项目，并计划部署到AWS Elastic Beanstalk。根据这些要求，我需要在没有人为干预的情况下运行manage.py命令（即django-background-tasks中的'process_tasks'）。

I have a Django project which I'm using Docker and plan to deploy to AWS Elastic Beanstalk. Based on these requirements, I need to run a manage.py command (namely 'process_tasks' from django-background-tasks) without human intervention.

如果我的理解正确的话，必须运行'process_tasks'，否则任务将无法在计划的时间执行。

If my understanding is correct, 'process_tasks' must be run otherwise the tasks will not be executed at the scheduled time.

我想出了以下解决方案，将其添加到docker-compose.yml中。
问题是我在服务器启动时在 urls中调用后台任务，因此该解决方案导致将任务两次添加到数据库中。我的目标是每天在特定时间运行后台任务。
我缺少一个更简单的解决方案吗？

I came up with the following solution to add in my docker-compose.yml. The problem is I call my background task in 'urls' on server start and somehow this solution results in adding the task to the db twice. My objective is to run a background task everyday at a certain time. Is there a simpler solution I'm missing?

  web:
    build: .
    command: python3 manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

  tasks:
    build: .
    command: python3 manage.py process_tasks
    volumes:
      - .:/code
    depends_on:
      - web
      - db 

推荐答案

web:
 build:
    context:./containerfolder


volumes:
  - .:/code
ports:
  - "8000:8000"
depends_on:
  - db

在您的容器docker文件内部写入命令python3 manage.py runserver和python3 manage.py process_tasks

in-side your container docker file write your commands like python3 manage.py runserver and python3 manage.py process_tasks
