This repo contains the scripts and small NodeJS app to demonstrate GitOps example using Jenkins, Argocd & Kustomize

In this example, we will be using a simple NodeJS app to demonstrate the GitOps workflow. The app is a simple NodeJS app that returns the simple hello world. The app is deployed in a Kubernetes cluster and the deployment is managed by ArgoCD. The ArgoCD deployment is managed by Jenkins. The Jenkins pipeline is triggered by a commit to the GitOps repo. The GitOps repo contains the Kubernetes manifests and the Kustomize files to deploy the app.
