+## What if I want to redeploy my application without changing configuration settings? 
+{: #update-app-nochange}
+
+You can always deploy your application with configuration changes by changing a configuration value and deploying the application. 
+
+However, you might want to redeploy an application revision without changing your application configuration settings. Perhaps your referenced container image is changed, and you want your application revision to use the updated container image. Or, perhaps you want your application to reference a secret or configmap, which contains updated content values. 
+
+For these scenarios, from the console, you can click **Redeploy** from the **Configuration** tab of your application page, without changing your app configuration. With the CLI, use the [**`ibmcloud ce app update`**](/docs/codeengine?topic=codeengine-cli#cli-application-update) command.
