Kubernetes Orchestration Demo

A comprehensive demonstration of Kubernetes orchestration capabilities, showcasing how to deploy, manage, and scale containerized applications in a Kubernetes environment.

Overview

This project demonstrates the deployment of a multi-service application on Kubernetes, including:

• API service
• Web frontend
• Crawler service
• Metrics server

The application showcases various Kubernetes concepts such as:

• Deployments
• Services
• ConfigMaps
• PersistentVolumeClaims
• Ingress
• Resource management

Prerequisites

• Kubernetes cluster (local or cloud-based)
• kubectl CLI tool
• Docker (for building images)

Getting Started

1. Clone this repository:

   git clone https://github.com/yourusername/k8s.git
   cd k8s

2. Apply the Kubernetes configurations:

   kubectl apply -f api-configmap.yaml
   kubectl apply -f api-pvc.yaml
   kubectl apply -f api-deployment.yaml
   kubectl apply -f crawler-service.yaml
   kubectl apply -f web-deployment.yaml
   kubectl apply -f app-ingress.yaml

3. Verify the deployment:

   kubectl get pods
   kubectl get services

Architecture

The application consists of the following components:

• API Service: Backend service that handles data processing
• Web Frontend: User interface for interacting with the application
• Crawler Service: Service for data collection and processing
• Metrics Server: Provides monitoring capabilities

Configuration

The application uses ConfigMaps to manage configuration settings. Key configuration files include:

• api-configmap.yaml: Contains API service configuration
• crawler-service.yaml: Defines the crawler service

Troubleshooting

If you encounter issues with the deployment:

1. Check the status of pods:

   kubectl describe pod <pod-name>

2. View logs:

   kubectl logs <pod-name>

3. Verify ConfigMap and PVC status:

   kubectl get configmap
   kubectl get pvc
