Node.js Application Deployment on Kubernetes Cluster

This project outlines the deployment of a Node.js application on a local Kubernetes cluster using ArgoCD for continuous delivery. The build and deployment process is automated with a Jenkins pipeline.

Prerequisites

• VM for Jenkins
• Docker installed on the Jenkins VM
• VM for Minikube and kubectl
• Minikube installed on the second VM
• ArgoCD installed on Minikube
• Jenkins installed on the first VM
• GitHub account
• Docker Hub account

---

Part 1: Jenkins Setup and Dockerization

Step 1: Fork the Repository

1. Go to the Node.js GitHub repository.
2. Fork the repository to your GitHub account.

Step 2: Clone the Repository on Your VM

git clone https://github.com/mo8310/nodejs.org.git
cd nodejs.org

Step 3: Build and Run Locally

• Install dependencies:

  npm install

• Run the development server:

  npx turbo dev

• The site should now be available at http://localhost:3000.

Step 4: Test

• Ensure the application is functioning as expected by running:

  npm test

Step 5: Dockerize the Application

• Create and Build a dockerfile in the project directory and Push the Dockerfile to repo.

Step 6: Set Up Jenkins Pipeline

• Install Docker on Jenkins VM to allow Jenkins to build Docker images and Create a Jenkins pipeline
• Set up Docker Hub credentials in Jenkins to enable pushing images.

Part 2: Kubernetes Deployment

Step 1: Install Minikube and ArgoCD on the Second VM

1. Install Minikube and kubectl:

   curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
   sudo install minikube /usr/local/bin/
   minikube start

2. Install ArgoCD:

   kubectl create namespace argocd
   kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

3. Access ArgoCD Dashboard:

   kubectl port-forward svc/argocd-server -n argocd 8080:443

Step 2: Deploy the Node.js App to Kubernetes

1. Create a deployment.yaml for service and app and Push to my repo.
2. Configure ArgoCD to point to my GitHub repo for continuous delivery.
