# Dockerizing-a-Django-and-MySQL-Application

How to Connect your MySQL Database to your Dockerized Django Application.  making it easier to develop and deploy. In this tutorial, we will walk you through the process of dockerizing a Django and MySQL application.

### Step 1: Create a Dockerfile

In your Django project’s root directory, create a Dockerfile. This file defines how your Django application should be built inside a Docker container. Here's a basic Dockerfile for a Django application:

```dockerfile

FROM python:3.10.2

ENV PYTHONUNBUFFERED 1

COPY ./requirements.txt /requirements.txt

RUN pip install --upgrade pip

RUN apt-get update

RUN pip install -r /requirements.txt

RUN mkdir /app

COPY . /app

WORKDIR /app

```

### Step 2: Create a docker-compose.yaml File

Next, create a docker-compose.yaml file in your project's root directory. This file defines the services and their configurations, including the Django application and MySQL database. Here's a basic docker-compose.yaml

```yml

version: '3.9'

services:

  django:

    image: dev_image

    container_name: dev

    build: .

    restart: always

    ports:

      - 8000:8000

    volumes:

      - .:/app

    command: sh -c "python3 manage.py makemigrations && python3 manage.py migrate && python3 manage.py runserver 0.0.0.0:8000"

    env_file:

      - .env

    depends_on:

      - db

    

  db:

    image: mysql

    container_name: mysql_db

    restart: always

    ports:

      - 3307:3306

    volumes:

      - data:/var/lib/mysql

    environment:

      MYSQL_ROOT_PASSWORD: ${DATABASE_ROOT_PASSWORD}

      MYSQL_DATABASE: ${DATABASE_NAME}

      MYSQL_USER: ${DATABASE_USER}

      MYSQL_PASSWORD: ${DATABASE_PASSWORD}

volumes:

  data:

```

### Step 3: Set Environment Variables

Create a .env file in your project's root directory to store environment variables for your Django application and MySQL database. Here's an example .env file

```env

DATABASE_NAME=db_name

DATABASE_USER=username

DATABASE_PASSWORD=password

DATABASE_HOST=db

DATABASE_PORT=3306

DATABASE_ROOT_PASSWORD=root-password

```

### Step 4: Configure Django Settings 

In your Django project’s settings.py, make sure you read environment variables for sensitive information like SECRET_KEY and database settings. For example:

```python

DATABASES = dict(default={

    'ENGINE': 'django.db.backends.mysql',

    'NAME': str(os.getenv('DATABASE_NAME')),

    'USER': str(os.getenv('DATABASE_USER')),

    'PASSWORD': str(os.getenv('DATABASE_PASSWORD')),

    'PORT': str(os.getenv('DATABASE_PORT')),

    'PORT': '3306',

    'OPTIONS': {

        'charset': 'utf8mb4',

    }

})

```
