# Containerization of a Web Microservice using Docker and Kubernetes Orchestration
## Introduction
Containerized `Node microservice` using `Docker` and then deployed it on `Google Kubernetes Engine` using the provided manifest files. This setup includes configurations for Pods, Deployments, and Services **(NodePort and LoadBalancer)**.

## Prerequisites
- Kubernetes cluster
- `kubectl` configured to interact with your cluster
## Manifests
- **Pod Manifest**
- Single instance of the application
- Container specification with image and ports
- Liveness and readiness probes for health checks
- **Deployment Manifest**
- Replica sets for high availability and scalability
- Rolling updates strategy
- Resource requests and limits
- Liveness and readiness probes
- **NodePort Service Manifest**
- Exposes service on a static port across all nodes
- Access via `:`
- **LoadBalancer Service Manifest**
- External load balancer creation
- Cloud provider-specific (e.g., AWS, GCP, Azure)
- Access via external IP provided by the load balancer
## Deployment Instructions
1. Apply the manifests:
```sh
kubectl apply -f pod.yaml
kubectl apply -f deployment.yaml
kubectl apply -f svc_np.yaml
kubectl apply -f svc_lb.yaml
```
2. Verify deployments and services:
```sh
kubectl get pods
kubectl get deployments
kubectl get services
```
## Accessing the Application
- **NodePort**
- Access the application using `:`
- Example: `http://:30001`
- **LoadBalancer**
- Access the application using the external IP assigned by the load balancer
- Example: `http://:4000`
## Health Checks
- **Liveness Probe**: `/healthz`
- **Readiness Probe**: `/readiness`
- Ensures the application is running and ready to serve traffic
## Clean Up
1. Delete the resources:
```sh
kubectl delete -f pod.yaml
kubectl delete -f deployment.yaml
kubectl delete -f svc_np.yaml
kubectl delete -f svc_lb.yaml
```

Due to high incurring charges for Google Kubernetes Engine service at Google Cloud, The Web page has been taken down. However, I have provided the link to Docker image of the API.
