Git and CI/CD Integration

 

Git and CI/CD Integration Guide

Git is the foundation of modern DevOps.

What is CI/CD?

  • CI (Continuous Integration) → Automatically test code on every push

  • CD (Continuous Delivery/Deployment) → Automatically deploy code

Popular CI/CD tools:

  • Jenkins

  • GitHub Actions

  • GitLab CI/CD

How Git Triggers CI/CD

Workflow:

  1. Developer pushes code

  2. Remote repository detects push

  3. Pipeline runs automatically

  4. Tests executed

  5. Build created

  6. Deploy to staging/production

Example: GitHub Actions Workflow

Create file:

.github/workflows/django.yml

Example:

name: Django CI

on:
  push:
    branches: [ "main" ]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v3
      - name: Install dependencies
        run: pip install -r requirements.txt
      - name: Run Tests
        run: python manage.py test

Every push to main triggers automated tests.

Branch Protection Rules

In production projects:

  • Protect main branch

  • Disallow direct push

  • Require PR

  • Require CI pass before merge

Real-World Workflow (Backend Team Example)

For a Django backend project:

  1. Create feature branch

  2. Develop API

  3. Push branch

  4. Create PR

  5. CI runs tests

  6. Team reviews code

  7. Merge to develop

  8. Release branch created

  9. Deploy to production

If you're a backend developer, mastering Git beyond basics gives you:

  • Clean commit history

  • Safe collaboration

  • Faster releases

  • Production confidence

Database Integration in FastAPI (SQLAlchemy CRUD)

  Introduction So far, we’ve built APIs without storing data.But real-world applications need a database to: Store user data. Manage products. Persist application state. In this blog, we’ll connect FastAPI with a database using SQLAlchemy and perform CRUD operations . What is SQLAlchemy? SQLAlchemy is a powerful Python ORM (Object Relational Mapper) that allows you to: Interact with databases using Python code. Avoid writing raw SQL queries. Work with models instead of tables. Step 1: Install Dependencies pip install sqlalchemy (For SQLite, no extra driver needed) Project Structure Update app/ ├── main.py ├── database/ │ ├── connection.py ├── models/ │ ├── item.py ├── schemas/ │ ├── item.py ├── routes/ │ ├── item.py Step 2: Database Connection app/database/connection.py from sqlalchemy import create_engine from sqlalchemy . orm import sessionmaker , declarative_base DATABASE_URL = "sqlite:///./test.db" engine = create_engine ( DAT...

Middleware & CORS in FastAPI

  Introduction As your API grows, you may need to: Log requests Modify responses Handle cross-origin requests This is where Middleware and CORS (Cross-Origin Resource Sharing) come into play.They help control how requests and responses flow through your application. What is Middleware? Middleware is a function that runs: Before a request reaches your route After a response is returned Think of it as a pipeline layer between client and server. Request Flow with Middleware Client → Middleware → Route → Middleware → Response Creating Custom Middleware from fastapi import FastAPI , Request import time app = FastAPI () @ app . middleware ( "http" ) async def log_requests ( request : Request , call_next ): start_time = time . time() response = await call_next ( request ) process_time = time . time() - start_time print ( f"Request: { request . url} | Time: { process_time } " ) return response What This Middle...
