Django +芹菜+ Nginx

Question

我试着用芹菜和Nginx在码头运行django应用程序。

Docker-compose

version: '3'

services:
  helpdesk_web:
    build:
      context: ./
      dockerfile: Dockerfile
    container_name: helpdesk_web
    volumes:
      - ./static:/usr/src/app/static
      - media:/usr/src/app/media
    ports:
      - "8000:8000"
      - "5678:5678"
    env_file:
      - ./.env
    restart: always
    depends_on:
      - helpdesk_db
      - helpdesk_redis

  helpdesk_db:
    image: postgres
    container_name: helpdesk_db
    volumes:
      - postgres_data:/var/lib/postgresql/data/
    env_file:
      - ./.env
    ports:
      - "5432:5432"
    environment:
      POSTGRES_DB: helpdesk_db
      POSTGRES_PASSWORD: itds
      POSTGRES_USER: itds

  nginx:
    build:
      context: ./docker/nginx
      dockerfile: Dockerfile
    container_name: helpdesk_nginx
    restart: on-failure
    depends_on:
      - helpdesk_web
      - helpdesk_db
    ports:
      - "80:80"
    volumes:
      - ./static:/usr/src/app/static
      - media:/usr/src/app/media
  
  helpdesk_redis:
    image: redis
    ports: 
      - "6379:6379"
  
  helpdesk_celery:
    build: 
      context: .
      dockerfile: Dockerfile
    command: celery -A helpdesk worker -l INFO --pool=solo
    depends_on:
      - helpdesk_web
      - helpdesk_redis
  
  helpdesk_celery-beat:
    build: 
      context: .
      dockerfile: Dockerfile
    command: celery -A helpdesk beat -l INFO --scheduler django_celery_beat.schedulers:DatabaseScheduler
    depends_on:
      - helpdesk_web
      - helpdesk_redis

volumes:
  postgres_data:
  media:

Dockerfile

FROM python:3.10


WORKDIR /usr/src/app


ENV PYTHONDONTWRITEBYTECODE 1

ENV PYTHONUNBUFFERED 1

RUN pip install --upgrade pip


COPY requirements.txt .

RUN pip install -r requirements.txt

COPY . .

RUN chmod +x entrypoint.sh

ENTRYPOINT ["/usr/src/app/entrypoint.sh"]

entrypoint.sh

#! /bin/sh
if [ "$DATABASE" = "postgres" ]
then
    echo "Waiting for postgres..."
    while ! nc -z $SQL_HOST $SQL_PORT; do
      sleep 0.1
    done
    echo "PostgreSQL started"
fi
python manage.py migrate --no-input
exec gunicorn helpdesk.wsgi:application -b 0.0.0.0:8000 --workers=$WORKERS_COUNT

当我运行坞-撰写时，我会得到这个错误。

​

我有没有nginx的开发坞-撰写，它工作得很好。芹菜和银杏之间似乎存在一些问题。我是个初学者，所以我不知道该怎么做。

我遗漏了什么？

编辑№1:这就像芹菜和芹菜-节拍被设定为火鸟.

Compose command:覆盖Dockerfile CMD，并且是passed as arguments to the ENTRYPOINT。一个典型的设置是让您的入口点脚本进行第一次设置，就像等待数据库一样，但最后以特殊的shell命令exec "$@"结束，以运行作为参数传递给它的命令。

#!/bin/sh
# Wait for the database, run migrations, set environment variables, ...
if [ "$DATABASE" = "postgres" ]; then ...; fi
python manage.py migrate --no-input

# Run the command passed as arguments, not a fixed command here
exec "$@"

在您的Dockerfile中，声明您希望容器运行的默认CMD，如GUnicorn。

ENTRYPOINT ["/usr/src/app/entrypoint.sh"]
CMD gunicorn helpdesk.wsgi:application -b 0.0.0.0:8000 --workers=$WORKERS_COUNT

现在，它将尊重Compose command:，或另一个命令docker-compose run。

version: '3.8'
services:
  web:
    build: .
    ports: ['8000:8000', '5678:5678']
    env_file: [.env]
    restart: always
    depends_on: [db, redis]
    # and the default image CMD
  celery:
    build: .
    command: celery -A helpdesk worker -l INFO --pool=solo
    depends_on: [redis]
  celery-beat:
    build: .
    command: celery -A helpdesk beat -l INFO --scheduler django_celery_beat.schedulers:DatabaseScheduler
    depends_on: [redis]
  db: { ... }
  redis: { image: redis }
