On this week's episode of the podcast, freeCodeCamp founder Quincy Larson interviews Rishab Kumar, cloud engineer and developer advocate at Twillio. Rishab grew up in India and moved to Canada for school. But he couldn't afford to finish. He resorted to delivering pizzas and working at a gas station. But he worked hard to teach himself how to code and how to build cloud infrastructure, and eventually got a job Google. Support for this podcast comes from a grant from Wix Studio. Wix Studio provides developers tools to rapidly build websites with everything out-of-the-box, then extend, replace, and break boundaries with code. Learn more at https://wixstudio.com. Support also comes from the 11,043 kind folks who support freeCodeCamp through a monthly donation.

“`bash
django-admin startproject myproject
cd myproject
“` #### **2️⃣ Create a Dockerfile**
Inside your Django project folder, create a file named `Dockerfile` and add the following content: “`dockerfile
# Use official Python image as base
FROM python:3.9 # Set environment variables
ENV PYTHONUNBUFFERED=1 # Set the working directory
WORKDIR /app # Copy project files to the container
COPY . /app/ # Install dependencies
RUN pip install –no-cache-dir -r requirements.txt # Expose the default Django port
EXPOSE 8000 # Run the Django server
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]
“` #### **3️⃣ Create a `.dockerignore` File**
“`plaintext
__pycache__/
*.pyc
*.pyo
db.sqlite3
.env
“` #### **4️⃣ Build the Docker Image**
Run the following command inside your Django project directory: “`bash
docker build -t my-django-app .
“` #### **5️⃣ Run the Docker Container**
“`bash
docker run -p 8000:8000 my-django-app
“` #### **6️⃣ Access Your Django App** Open your browser and go to: 🔗 [http://localhost:8000](http://localhost:8000) ### **Optional: Using Docker Compose for a Django + PostgreSQL Setup** We’ll also cover how to use `docker-compose.yml` to set up Django with a PostgreSQL database inside containers. ### **Who Is This Tutorial For?** – 🛠️ Developers looking to streamline their Django workflow with Docker – 💻 Beginners who want an easy way to package and run Django apps – 🚀 DevOps engineers preparing Django projects for production ### **Resources Mentioned in This Video:** – Docker Documentation: [https://docs.docker.com/](https://docs.docker.com/) – Django Official Docs: [https://docs.djangoproject.com/](https://docs.djangoproject.com/) – Source Code (GitHub): *[Link if applicable]* ### **Pro Tips for Success:** ✅ Use `.dockerignore` to keep unnecessary files out of your image. ✅ Bind mount volumes for easy development without rebuilding the image every time. ✅ Use Docker Compose for managing multiple services like databases. ### **Don’t Forget to Subscribe!** If you found this tutorial helpful, please like, comment, and subscribe for more Django and DevOps content!
