This roadmap will guide you from the basics to advanced concepts of microservices architecture, covering development, deployment, security, and real-world applications.
🗓️ Day 1-10: Getting Started with Microservices
✓ to Microservices: Understand the fundamentals.
✓ Benefits & Drawbacks: A balanced view of microservices.
✓ Development Setup: Prepare your environment.
✓ First Microservice: Build and run your first service.
✓ REST API Fundamentals: Learn to create and consume REST APIs.
You Should Know:
- Basic REST API Commands (cURL):
curl -X GET https://api.example.com/users curl -X POST -H "Content-Type: application/json" -d '{"name":"John"}' https://api.example.com/users - Starting a Simple HTTP Server (Python):
python3 -m http.server 8000
🗓️ Day 11-20: Diving into Containers and APIs
✓ Docker Overview: What is Docker? Why it matters.
✓ Docker Installation: Get Docker running.
✓ Creating a Docker Image: Master container management.
✓ OpenAPI Specification: Learn OpenAPI specs.
You Should Know:
- Basic Docker Commands:
docker pull nginx docker run -d -p 8080:80 --name mynginx nginx docker ps -a docker build -t myapp .
- Generating OpenAPI Specs (Swagger):
npm install -g swagger-cli swagger-cli validate api-spec.yaml
🗓️ Day 21-30: Advanced Microservices Concepts
✓ Decomposition Patterns: Domain-Driven Design.
✓ Database Patterns: Database per Service.
✓ Kubernetes : Minikube & Kubernetes basics.
You Should Know:
- Minikube Startup:
minikube start kubectl get pods
- Deploying a Sample App:
kubectl create deployment nginx --image=nginx kubectl expose deployment nginx --port=80 --type=NodePort
🗓️ Day 31-40: Kubernetes and Security Essentials
✓ Kubernetes Fundamentals: Pods, Services, Deployments.
✓ Security Essentials: OAuth, RBAC, Input Validation.
You Should Know:
- Kubernetes Security (RBAC):
kubectl create role developer --verb=get,list --resource=pods kubectl create rolebinding dev-binding --role=developer --user=dev-user
- Input Validation (Python Flask):
from flask import Flask, request, jsonify app = Flask(<strong>name</strong>) </li> </ul> @app.route('/submit', methods=['POST']) def submit(): data = request.get_json() if not data.get('username'): return jsonify({"error": "Username required"}), 400 return jsonify({"success": True})🗓️ Day 41-50: Advanced Security & Resilience
✓ Defence-in-Depth & Encryption
✓ Resilience Patterns: Circuit Breaker, Retry, Fallback.
You Should Know:
- Implementing Circuit Breaker (Resilience4j):
CircuitBreakerConfig config = CircuitBreakerConfig.custom() .failureRateThreshold(50) .waitDurationInOpenState(Duration.ofMillis(1000)) .build(); CircuitBreaker circuitBreaker = CircuitBreaker.of("myService", config);
🗓️ Day 51-70: Observability & Deployment Strategies
✓ Distributed Tracing (Jaeger/Zipkin)
✓ Blue-Green & Canary Deployments
You Should Know:
- Jaeger Setup (Docker):
docker run -d -p 16686:16686 -p 6831:6831/udp jaegertracing/all-in-one
- Canary Deployment (Kubernetes):
kubectl set image deployment/myapp myapp=myapp:v2 --record kubectl rollout status deployment/myapp
🗓️ Day 71-100: Final Project & Real-World Use Cases
✓ Build & Deploy a Microservices App
✓ Testing & OWASP Top 10 Security
You Should Know:
- OWASP Security Scanning (ZAP):
docker run -v $(pwd):/zap/wrk -t owasp/zap2docker zap-baseline.py -t https://example.com
What Undercode Say:
Microservices architecture requires mastering Docker, Kubernetes, API security, and observability tools. Key takeaways:
– Use `kubectl` for Kubernetes management.
– Secure APIs with OAuth2 & RBAC.
– Monitor with Jaeger/Prometheus.
– Automate deployments with CI/CD pipelines.Expected Output:
A fully functional, secure, and observable microservices application deployed on Kubernetes with automated scaling and resilience.
