This project serves as a playground for experimenting with Spring Boot API development. It provides a basic API structure that can be used as a foundation for testing and learning Spring Boot concepts.

The project includes:

• Basic REST endpoints (/, /actuator/health, /posts)
• Entity management with JPA
• Error handling
• Integration tests

This API was created as a base playground for experimenting with Spring Boot features and concepts. It's designed to be simple enough to understand quickly, yet structured in a way that allows for easy expansion and experimentation.

• Java JDK
• Maven

mvn spring-boot:run

mvn test

• GET / - Index endpoint, returns "ok"
• GET /posts/{id} - Get a specific posts by ID
• GET /postss - List all posts
• POST /posts - Create a new posts

docker build -t post-api:latest .

docker run -p 8080:8080 post-api:latest

Apply the Kubernetes manifests in your cluster:

kubectl apply -f k8s-deployment.yaml

This will create a Deployment and Services for the API. You can port-forward to access the services:

kubectl port-forward svc/post-api-cluster 8090:80
kubectl port-forward svc/post-api-lb 8080:80

You can then access them on localhost:8090 and 8080 respectively

minikube start
minikube image load post-api:latest

After applying the manifest you can either port-forward as above or use minikube service post-api-lb to find the url to access the service.

You can also manage the cluster using minikube dashboard if preferred to command line.

If you want to access your API via a LoadBalancer service (external to cluster and port 80), apply the manifest and run:

minikube tunnel

This will expose the post-api-lb service on a local IP. You can get the external IP with:

kubectl get svc post-api-lb

Then access your API at http://<external-ip>/.
