Following the Django tutorial from the amazing CodingEntrepreneurs Youtube Channel, this focuses on building a modern fullstack Django web application while using modern DevOps tooling to help build production grade Django Web apps.

Django Auto Container

This repository contains a GitHub Actions workflow that automatically builds a Django-based container application and pushes it to Docker Hub using Buildpacks. You can import the repository on your Django Project from CodingEntrepreneurs github repository.

The purpose of this repo is to help Django devs use containers without having to learn Docker.

Getting Started

1. Copy the Build Container Workflow this Repository

Navigate to your Django project directory and copy the build container workflow from this repository.

mkdir -p .github/workflows
curl https://raw.githubusercontent.com/codingforentrepreneurs/django-auto-container/main/.github/workflows/build-container.yaml > .github/workflows/build-container.yaml

2. Github Actions Secrets

In your GitHub Repo, add the following Secrets:

Required Secrets

If you do not include these secrets, the container will be built but not hosted anywhere.

  • DOCKER_HUB_USERNAME: Your Docker Hub username.
  • DOCKER_HUB_TOKEN: Your Docker Hub access token; create a new token here.

Recommended Secrets

These secrets are highly recommended to add for your specific project.

  • DOCKER_HUB_REPO: The Docker repository to push to, in the format username/repository. Defaults to the format of your GitHub repo if not set -- this is where you will store your container.
  • BASE_DIR: The default Django project location is src/ as you see in this repo. If you have a different location, you can set it here.

Optional Secrets

If you need more advanced usage, consider adding these secrets to modify how your project works.

  • BUILDPACK_BUILDER: The buildpack builder to use. Defaults to 'heroku/buildpacks:22' if not set. Review various Heroku buildpacks here
  • DOCKER_HUB_IMAGE_TAG: The tag to use for the Docker image. Defaults to the commit SHA (recommended) or you can set this value yourself.

3. Required Files

In my BASE_DIR (defaults to src/), I have the following files:

  • project.toml
  • requirements.txt

This files are needed to ensure the auto-container workflow runs correctly, review src/ for working examples or use the following samples:

project.toml

[[build.env]]
name = "DISABLE_COLLECTSTATIC"
value = "1"

[[build.env]]
name =  "GOOGLE_RUNTIME_VERSION"
value = "3.11.7"

[[build.env]]
name = "GOOGLE_ENTRYPOINT"
value = "gunicorn cfehome.wsgi:application --bind \"0.0.0.0:$PORT\""

The GOOGLE_ENTRYPOINT is the command that will be run when the container is started. In this case, it's the production version of running python manage.py runserver but with gunicorn instead of runserver.

requirements.txt

Django
gunicorn

gunicorn is required as it's what is recommended to run Django in production.

4. Push

Push your code to GitHub and watch the magic happen. You can view the workflow in the "Actions" tab of your GitHub repo.

5. Run

If you have Docker installed locally, you can run your application with:

docker run -e PORT=8888 -p 8888:8888 <your-docker-hub-username>/<your-docker-hub-repo>:<your-docker-hub-image-tag>

Open http://localhost:8888 to view your application.

If you don't have Docker installed locally, you can run your application on any container host such as:

  • Kubernetes
  • Knative
  • Hashicorp Nomad
  • Any managed container hosting service
