Python FastAPI - Mini DevOps CI/CD Assessment

Technology Stack

• Python 3.11+
• FastAPI
• Uvicorn
• Docker
• Jenkins
• Kubernetes

---

Objective

Automate the build, Docker image creation, Docker image push, and Kubernetes deployment of a FastAPI Inventory REST API.

---

REST Endpoints

Method| Endpoint| Description GET| "/health"| Health check GET| "/products"| Retrieve all products POST| "/products"| Add a product

Use an in-memory list. No database is required.

---

Module 1 - Run the Application

Application URL

http://localhost:8000

Swagger

http://localhost:8000/docs

Verify

GET /health GET /products

---

Module 2 - Dockerize the Application

Create a "Dockerfile".

Verify:

• Docker image builds successfully.
• Container starts successfully.
• Health endpoint is reachable.

---

Module 3 - Jenkins Pipeline

Create a Declarative "Jenkinsfile" containing:

1. Checkout
2. Install Dependencies
3. Docker Build
4. Docker Push

Docker image format:

/python-inventory-api:${BUILD_NUMBER}

---

Module 4 - Kubernetes Deployment

Create:

• "deployment.yaml"
• "service.yaml"

Requirements:

• Replicas = 2
• NodePort Service

Deploy

kubectl apply -f deployment.yaml kubectl apply -f service.yaml

Verify

kubectl get pods kubectl get svc

---
