Restart `the-first-vm`: \n\n gcloud compute instances reset the-first-vm\n\nThe instance might take some time to start back up. Wait a couple minutes before\nconfirming the change.\n\n### Confirm the new startup script\n\n1. Get the external IP of `the-first-vm`:\n\n gcloud compute instances describe the-first-vm | grep \"natIP\"\n\n2. Copy the value.\n\n3. Open a browser and paste the IP address into the address bar to visit your\n instance.\n\n The page should now show a welcome message that says\n \"Deployment Manager bids you good day!\"\n\nYou can also repeat these steps with `the-second-vm` and see a slightly\ndifferent message.\n\nDelete your deployment\n----------------------\n\nAs with previous steps, we recommend that you delete the deployment to avoid\ncharges. Run the following command to delete the deployment: \n\n gcloud deployment-manager deployments delete deployment-to-update\n\nWhat's next\n-----------\n\nHere are some areas to explore as you use Deployment Manager more:\n\n- [Explore more complex tutorials](/deployment-manager/docs/tutorials)\n- [Learn about available resource types](/deployment-manager/docs/configuration/supported-resource-types)\n- [Learn more about environment variables](/deployment-manager/docs/configuration/templates/use-environment-variables)\n- [Learn about importing Python libraries](/deployment-manager/docs/configuration/templates/import-python-libraries)\n- [Read the guidelines for preparing updates](/deployment-manager/docs/deployments/updating-deployments)"]]
