🚀 Getting Started

Deploy a Sample Application

This section walks you through deploying a sample web application that was used to create this guide.

  1. Create a Docker Image:

    Follow the Dockerfile and nginx.conf in the repository to build a Docker image for the sample application.

  2. Build and Push Docker Image:

    docker build -t web-app:latest .
docker tag web-app:latest your-dockerhub-username/web-app:latest
docker push your-dockerhub-username/web-app:latest

  3. Create a Kubernetes Deployment:

    kubectl create deployment web-app --image=your-dockerhub-username/web-app:latest

  4. Expose the Deployment:

    kubectl expose deployment web-app --port=80 --type=NodePort

  5. Verify Deployment and Service:

    kubectl get deployments
kubectl get services

    Sample Application Deployment

📜 Common Commands
