NodeJS Demo App - CI/CD Pipeline

This repository demonstrates automating code deployment using GitHub Actions.

Project Structure

• index.html → Sample web application
• Dockerfile → Docker image build configuration
• .github/workflows/main.yml → CI/CD workflow

Workflow Steps

1. Trigger: On push or pull request to main branch
2. Build: Docker image of the app
3. Run: Start container and expose port 8080
4. Test: Verify the app responds with "200 OK"
5. Cleanup: Stop and remove container

Tools Used

• GitHub & GitHub Actions - Docker nodejs-demo-app

Simple CI/CD Pipeline with Jenkins

This project demonstrates a basic CI/CD pipeline using Jenkins, Docker, and GitHub.

Steps

1. Clone this repo and set up Jenkins.
2. Add DockerHub credentials in Jenkins with ID dockerhub-creds.
3. Create a Pipeline or Multibranch Pipeline job pointing to this repo.
4. Configure a GitHub webhook: http://<jenkins-host>:8080/github-webhook/.
5. On every push:
   • Jenkins will build a Docker image.
   • Push it to DockerHub.
   • Deploy the app locally on Jenkins host (port 8080).

Test Open http://localhost:8080 after pipeline run.

Task 3 – Provision Docker Container using Terraform This project uses Terraform with the Docker provider to pull the nginx:alpine image and run a container named nginx_terraform mapped to port 8080. The setup demonstrates Infrastructure as Code by automating container provisioning, verification, and cleanup with terraform init, plan, apply, and destroy.

TASK 5 - Minikube Kubernetes Deployment Objective: Build a local Kubernetes cluster with Minikube and deploy a sample nginx app.

How to reproduce:

1. Install Docker, kubectl, minikube.
2. Start minikube: minikube start --driver=docker
3. Apply manifests:
   • kubectl apply -f deployment.yaml
   • kubectl apply -f service.yaml
4. Access service: minikube service my-nginx-svc --url
5. Scale: kubectl scale deployment/my-nginx --replicas=4
6. Rolling update example: kubectl set image deployment/my-nginx nginx=nginx:1.21.6

Task 6: Host a Static Website using GitHub Pages. The repo contains a simple index.html file (and optional CSS) to demonstrate how GitHub Pages can be used to host a static website directly from a repository.
