Welcome to the AWS CodeStar sample web application

This sample code helps get you started with a simple Django web application deployed by AWS CodeDeploy to an Amazon EC2 server.

What's Here

This sample includes:

  • - this file
  • appspec.yml - this file is used by AWS CodeDeploy when deploying the web application to EC2
  • buildspec.yml - this file is used by AWS CodeBuild to build and test your application
  • requirements/ - this directory contains requirements files that describe the Python dependencies required for your Django application in different environments
  • requirements.txt - this file is used to install production Python dependencies
  • ec2django/ - this directory contains your Django project files. Note that this directory contains a Django config file ( that includes a pre-defined SECRET_KEY. Before running in a production environment, you should replace this application key with one you generate (see for details)
  • helloworld/ - this directory contains your Django application files
  • - this Python script is used to start your Django web application
  • scripts/ - this directory contains scripts used by AWS CodeDeploy when installing and deploying your application on the Amazon EC2 instance
  • supervisord.conf - this configuration file is used by Supervisor to control your web application on the Amazon EC2 instance

Getting Started

These directions assume you want to develop on your local computer, and not from the Amazon EC2 instance itself. If you're on the Amazon EC2 instance, the virtual environment is already set up for you, and you can start working on the code.

To work on the sample code, you'll need to clone your project's repository to your local computer. If you haven't, do that first. You can find instructions in the AWS CodeStar user guide.

  1. Create a Python virtual environment for your Django project. This virtual environment allows you to isolate this project and install any packages you need without affecting the system Python installation. At the terminal, type the following command:

     $ virtualenv .venv
  2. Activate the virtual environment:

     $ activate ./venv/bin/activate
  3. Install development Python dependencies for this project:

     $ pip install -r requirements/dev.txt
  4. (Optional) Enable Django's debug mode for development:

     $ export DJANGO_DEBUG=True
  5. Start the Django development server:

     $ python runserver
  6. Open in a web browser to view your application.

What Do I Do Next?

Once you have a virtual environment running, you can start making changes to the sample Django web application. We suggest making a small change to /helloworld/templates/index.html first, so you can see how changes pushed to your project's repository are automatically picked up by your project pipeline and deployed to the Amazon EC2 instance. (You can watch the pipeline progress on your project dashboard.) Once you've seen how that works, start developing your own code, and have fun!

To run your tests locally, go to the root directory of the sample code and run the python test command, which AWS CodeBuild also runs through your buildspec.yml file.

To test your new code during the release process, modify the existing tests or add tests to the tests directory. AWS CodeBuild will run the tests during the build stage of your project pipeline. You can find the test results in the AWS CodeBuild console.

What Should I Do Before Running My Project in Production?

AWS recommends you review the security best practices recommended by the framework author of your selected sample application before running it in production. You should also regularly review and apply any available patches or associated security advisories for dependencies used within your application.

You can’t perform that action at this time.
