Meta Description (140 characters): Learn how to efficiently set up Docker with Django Rest Framework on Linux Ubuntu 20.04 using VS Code. A step-by-step guide for seamless integration.

Are you ready to supercharge your Django development process? Docker is the perfect tool to streamline your workflow and ensure consistent development environments. In this comprehensive guide, we'll walk you through the step-by-step process of setting up Docker with Django Rest Framework on a Linux Ubuntu 20.04 system using the powerful VS Code editor.

Step 1: Installing Docker

Begin your journey by installing Docker on your Linux Ubuntu 20.04 system. Open your terminal and follow these commands:

Update package index
sudo apt update

# Install required packages
sudo apt install apt-transport-https ca-certificates curl software-properties-common

# Add Docker repository
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu focal stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# Install Docker engine
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io

# Start and enable Docker
sudo systemctl start docker
sudo systemctl enable docker

# Verify Docker installation
sudo docker --version

Step 2: Setting Up Your Django Project

Navigate to your desired project directory and create a virtual environment:

# Create a virtual environment
python3 -m venv venv

# Activate the virtual environment
source venv/bin/activate

# Install Django and required packages
pip install django djangorestframework

Step 3: Dockerizing Your Django Application

Now, let's create Docker configurations for your Django project. In your project's root directory, create a Dockerfile with the following content:

# Use the official Python image
FROM python:3.9

# Set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

# Set the working directory
WORKDIR /app

# Install dependencies
COPY requirements.txt /app/
RUN pip install -r requirements.txt

# Copy project files
COPY . /app/

Step 4: Docker Compose for Seamless Integration

Docker Compose allows you to define and manage multi-container Docker applications. Create a docker-compose.yml file in your project's root directory:

version: "3.9"

services:

  app:

    build:

      context: .

      args:

        - DEV=true

    ports:

      - "8000:8000"

    volumes:

      - ./app:/app

    command: >

      sh -c "python https://manage.py/ wait_for_db &&

             python https://manage.py/ migrate &&

             python https://manage.py/ runserver 0.0.0.0:8000"

    environment:

      - DB_HOST=db

      - DB_NAME=devdb

      - DB_USER=devuser

      - DB_PASS=changeme

    depends_on:

               - db

  db:

    image: postgres:13-alpine

    volumes:

      - ./data/db:/var/lib/postgresql/data

    environment:

      - POSTGRES_DB=devdb

      - POSTGRES_USER=devuser

      - POSTGRES_PASSWORD=changeme

Step 5: Running Your Dockerized Django App

Execute the following commands to build and run your Dockerized Django application:

# Build the Docker images
sudo docker-compose build

# Start the application
sudo docker-compose up
