Heroku is a popular Platform-as-a-Service PaaS that allows developers to run and deploy applications by availing the infrastructure required in terms of hardware and software. This means that we do not have to invest in the hardware and software needed to expose our applications to end-users and this freedom allows us to concentrate on our business logic instead of deployment.
In this post, we will outline how to deploy a simple Django application to a Heroku pipeline. It targets existing Python developers and assumes a basic understanding of setting up and running a Django application.

When Heroku is deploying our application, it runs the command django-admin collectstatic , which bundles and saves all static files in the specified folder.
This folder will be in our project's root directory. With our Django application ready, Heroku requires us to include the following files in our project root so that it can be ready for deployment:. The purpose of this file is to specify the Python version that will be used to run our project. In our case, the file will just contain:. The contents of this file will be:.
