     --repo https://github.com/argoproj/argocd-example-apps.git \
     --path helm-guestbook \
     --dest-server https://cluster-<cluster-name>:8001 \
     --dest-namespace default
   • In dest-server URL (https://cluster-<cluster-name>:8001), replace <cluster-name> with the name used when connecting your Kubernetes cluster.

The helm-guestbook Application will be created but will not be synced automatically (because the sync policy was left to the default of Manual).

   argocd app diff helm-guestbook

2. Sync the Application.

   argocd app sync helm-guestbook
