Heroku is a cloud platform that allows developers to deploy, manage, and scale applications. In this tutorial, we'll walk through the process of deploying a Python web application on Heroku. We'll be using Flask as our web framework, but the steps are applicable to other frameworks as well.
Before we start, make sure you have the following:
For this tutorial, we'll use a simple Flask application. Create a new directory for your project and set up a virtual environment:
Install Flask:
Create a file named app.py with the following content:
Heroku uses the requirements.txt file to install the necessary dependencies. Generate this file by running:
A Procfile is a file that tells Heroku how to run your application. Create a file named Procfile (without any file extension) with the following content:
If you haven't initialized a Git repository yet, do so by running:
Log in to your Heroku account using the following command:
Follow the prompts to log in.
Create a new Heroku app:
Replace your-app-name with a unique name.
Deploy your app to Heroku using Git:
Open your app in the default web browser:
Congratulations! You've successfully deployed a Python web application on Heroku. Your app should be live, and you can share the provided Heroku app URL.
Remember, this tutorial covers the basics, and you can further customize your deployment based on your application's needs. Check the Heroku documentation for more advanced features and configurations.
