Install ArgoCD on kubernetes

install ArgoCD using the official manifest files provided by the ArgoCD team.

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

This will create a new namespace, argocd, where Argo CD services and application resources will live.

This command installs all the necessary ArgoCD components, including the API server, controller, and UI.
