Experiment with using Terraform to set up ArgoCD. Start by creating the necessary files. Then, initialize your Terraform configuration with terraform init, and apply the configuration using terraform apply. APPlication will be created inside argocd namespace, to get the secret run

k -n argocd get secrets argocd-initial-admin-secret \
-o jsonpath="{.data.password}"|base64 -d ;echo

to access the application with port forward run

k -n argocd port-forward svc/argocd-server 8080:80

website : http://127.0.0.1:8080

username : admin

password: token from previous secret
