### Updating your application
How about updating the app?  
```  
 $ kubectl edit deployment/update-demo  

 This opens up your default editor, and you can update the deployment on the fly. Find .spec.template.spec.containers[0].image and change nautilus to kitty. Save the file, and you’ll see:  

 deployment "update-demo" edited   
```  
You’re now updating the image of this app from “update-demo:nautilus” to “update-demo:kitty”.  Deployments allow you to update the app progressively, without a service outage.
