Capstone Project - Containerization and Container Orchestration

Project Overview

This project involves creating a simple static website and deploying it using Docker and Kubernetes. The primary goal is to containerize a frontend application, push it to Docker Hub, and deploy it to a Kubernetes cluster managed by Kind (Kubernetes in Docker).

Phase 1: Basic Frontend Application with Docker and Kubernetes

Tasks Overview

Task 1: Set up the Project

1. Create a new project directory.
2. Inside the directory, add the following files:
   • index.html (HTML file for the website)
   • styles.css (CSS file for styling)

Task 2: Initialize Git

• Initialize a Git repository in the project directory.

Task 3: Commit Initial Code

• Add and commit your code to the Git repository.

Task 4: Dockerize the Application

1. Create a Dockerfile using Nginx as the base image.
2. Copy the index.html and styles.css files into the Nginx HTML directory.

Task 5: Push to Docker Hub

1. Log in to Docker Hub.
2. Push the Docker image to your Docker Hub repository.

Task 6: Set Up a Kind Kubernetes Cluster

1. Install Kind (Kubernetes in Docker).
2. Create a Kind cluster.

Task 7: Deploy to Kubernetes

1. Create a Kubernetes Deployment YAML file to specify:
   • The Docker image
   • Desired replicas
2. Apply the deployment to the Kind cluster.

Task 8: Create a Service (ClusterIP)

1. Create a Kubernetes Service YAML file specifying the service type as ClusterIP.
2. Apply the service to your cluster.

Task 9: Access the Application

1. Port-forward the service to access the application locally.
2. Open your browser and navigate to the forwarded port to view the application.

Project Files

The following files will be included in the project:

• index.html (Frontend HTML content)
• styles.css (CSS styling)
• Dockerfile (To containerize the application using Nginx)
• my-nginx-deployment.yaml (Kubernetes Deployment configuration)
• my-nginx-service.yaml (Kubernetes Service configuration)

How to Run the Project

Prerequisites

• Docker installed on your system
• Kubernetes tools (e.g., kubectl and Kind)
• Docker Hub account

Steps

1. Clone this repository.
2. Build the Docker image:

   docker build -t <your-dockerhub-username>/<repository-name>:<tag> .

3. Push the Docker image to Docker Hub:

   docker push <your-dockerhub-username>/<repository-name>:<tag>

4. Create a Kind cluster:

   kind create cluster

5. Deploy the application:

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

6. Access the application:

   kubectl port-forward svc/<service-name> <local-port>:<service-port>

   Open your browser and navigate to http://localhost:<local-port>.
