Setting Up a CI Pipeline with GitHub Actions for a Python Web Application

Why CI/CD?

CI/CD pipelines automate the process of integrating code changes, running tests, and deploying applications. This enhances productivity, ensures consistent quality, and accelerates the delivery of applications.

Pipeline Overview

The CI pipeline includes the following steps:

Step 1: Create a GitHub Repository

Start by creating a GitHub repository for your Python web application.

Step 2: Add Your Application Code

Add your application code (app.py and test_app.py) and a requirements.txt file for dependencies.

Step 3: Set Up GitHub Actions Workflow

Create a .github/workflows/ci.yml file in your repository to automate the CI pipeline.

Step 4: Add Docker Hub Credentials

Add your Docker Hub credentials as secrets in your GitHub repository (DOCKER_USERNAME and DOCKER_PASSWORD).

Step 5: Commit and Push

Commit and push the changes to the main branch of your repository. The CI pipeline will automatically run on each push.

Key Takeaways

• Automation: This setup automates the entire process of building, testing, and deploying your application.

• Quality Assurance: Running tests ensures your application works correctly before deploying.

• Efficiency: Automating these tasks saves time and reduces the potential for human error.

By implementing this CI pipeline, you can ensure a consistent and reliable deployment process for your Python web applications.
