A Node.js application is deployed from the Node.js GitHub repository to a local Kubernetes cluster (Minikube), utilizing ArgoCD for continuous delivery and Jenkins for automated CI/CD. This architecture optimizes deployment workflows, ensuring both efficient and reliable application delivery.
- Virtual Machine (VM) for Jenkins - Includes Docker installed.
- VM for Minikube - Installed with Minikube, kubectl, and ArgoCD.
- Required Accounts - GitHub and Docker Hub.
- Install Docker on the Jenkins VM.

- Add Jenkins to docker group using
sudo usermod -aG docker jenkinsto allow machine access Docker
- Make Sure that
DockerandNodeJSPlugins are installed
Create a Job and run Buildnow.
- Make sure that the Docker image pushed to Docker Hub
- Install Minikube and kubectl on the second VM.
Install Kubernetes on Ubuntu/Debian

to get password
kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d; echo
and portforward
kubectl port-forward svc/argocd-server -n argocd 8080:443
