+# Setup Port-Forwarding
+As we are working in a simple kind cluster without ingress or Service LB support we will use a port-forward to the ArgoCD Server to access ArgoCD from the CLI or the UI
+```bash
+kubectl port-forward -n argocd svc/argocd-server 8080:443 &
+```
+
+# Configure the ArgoCD CLI
+```bash
+export ARGOCD_ADMIN_PASSWORD=`kubectl get secret -n argocd argocd-initial-admin-secret -o jsonpath='{.data.password}' | base64 --decode`
+argocd login --username admin --password $ARGOCD_ADMIN_PASSWORD localhost:8080 --insecure
+```
+
+# Open the ArgoCD UI
+* Retrieve the Admin Password
+  ```bash
+  export ARGOCD_ADMIN_PASSWORD=`kubectl get secret -n argocd argocd-initial-admin-secret -o jsonpath='{.data.password}' | base64 --decode`
+  echo "ArgoCD Admin Password: ${ARGOCD_ADMIN_PASSWORD}"
+  ```
+* Go to https://localhost:8080
+* Login with the username `admin` and the password retrieved above
+
+# Stop the Port Forward
+```bash
+kill $(ps -ef | grep '[k]ubectl port-forward -n argocd svc/argocd-server' | awk '{print $2}')
+```
