docker compose

1

I'm trying to create a docker environment for my django project

my dockerfile :

 FROM python:3
 ENV PYTHONUNBUFFERED=1
 RUN apt-get install default-libmysqlclient-dev
 RUN mkdir /config  
 ADD /config/requirements.txt /config/  
 RUN pip install -r /config/requirements.txt
 RUN mkdir /src
 WORKDIR /src

my docker-compose :

 version: '3'

services:
   db:
     image: mysql
     environment:
       MYSQL_ROOT_PASSWORD: root
       MYSQL_USER: root
       MYSQL_PASSWORD: root
       MYSQL_DATABASE: ProjetDjango
     container_name: mysql01
     restart: always
   nginx:
     image: nginx:1.13-alpine
     container_name: nginx01
     ports:
       - "8000:8000"
     volumes:
       - ./project:/src
       - ./config/nginx:/etc/nginx/conf.d
     depends_on:
       - web
   web:
     build: .
     container_name: django01
     command: bash -c "python3 manage.py makemigrations && python3 manage.py migrate && python3 manage.py collectstatic --noinput && gunicorn hello_django.wsgi -b 0.0.0.0:8000"
     depends_on:
       - db
     volumes:
       - ./project:/src
     expose:
       - "8000"
     restart: always

my settings.py :

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.mysql',
    'NAME': 'ProjetDjango',
    'USER': 'root',
    'PASSWORD': 'root',
    'HOST': '127.0.0.1', 
    'PORT': '3306',
 }
}

I've got this error while running : docker-compose up

When you link your db service to your web service in docker so you must use your db service name instead of your database server ip for connecting database :

db:
    image: mysql
    restart: unless-stopped
    container_name: db_of_my_project

web:
    build: .
    container_name: django01
    command: ...
    links:
        - db
    volumes:
        - ./project:/src
    expose:
        - "8000"
    restart: always
