Deploy on Kubernetes

Pre-requisites:

• Kubernetes cluster
• kubectl & ArgoCD CLI installed
• Configured Jenkins Pipeline

Setup Kubernetes Manifests:

kubectl create namespace chat-cluster
kubectl apply -f k8s_manifest/

#verify
kubectl get pods -n chat-cluster
kubectl get svc -n chat-cluster

If using minikube:

• use minikube service chat-frontend -n chat-cluster to access frontend in the browser.

Kubernetes Manifests fetches images from my dockerhub repo. Edit manifest files to use your built images.

CI/CD Pipeline with Jenkins & ArgoCD

Pipeline Overview:

1. Jenkins builds and pushes Docker images to Docker Hub
2. ArgoCD syncs Kubernetes manifests to AKS
3. Automated deployment & monitoring

Trigger the Pipeline

• Automatically via GitHub Webhook
• Manually in Jenkins
