# Step 5: Use the CodeDeploy console to deploy your Amazon ECS service
<a name="tutorial-ecs-with-hooks-deployment"></a>

 In this section, you update your deployment group by specifying the port for your test listener. This is the listener you created in [Step 1: Create a test listener](tutorial-ecs-with-hooks-create-second-listener.md). During deployment, CodeDeploy runs your validation test during the `AfterAllowTestTraffic` deployment lifecycle hook using test traffic served to your replacement task set using the test listener. Your validation test returns the result `Succeeded`, so the deployment proceeds with the next deployment lifecycle event. In a real world scenario, your test function returns `Succeeded` or `Failed`. 

**To add a test listener to your deployment group**

1. Sign in to the AWS Management Console and open the CodeDeploy console at [https://console.aws.amazon.com/codedeploy/](https://console.aws.amazon.com/codedeploy/).

1. From the navigation pane, choose **Applications**. 

1. Choose the application you created in [Tutorial: Deploy an application into Amazon ECS](tutorial-ecs-deployment.md). If you used the suggested name, it is **ecs-demo-codedeploy-app**.

1. In **Deployment groups**, choose the deployment group you created in [Tutorial: Deploy an application into Amazon ECS](tutorial-ecs-deployment.md). If you used the suggested name, it is **ecs-demo-dg**.

1.  Choose **Edit**. 

1. From **Test listener port**, choose the port and protocol for the test listener you created earlier in this tutorial. This should be **HTTP: 8080**. 

1.  Choose **Save changes**. 

**To deploy your Amazon ECS application**

1. From your deployment group console page, choose **Create deployment**.

1.  For **Deployment group**, choose **ecs-demo-dg**. 

1.  For **Revision type**, choose **My application is stored in Amazon S3**. In **Revision location**, enter the name of your S3 bucket and AppSpec file (for example, **s3://my-s3-bucket/appspec.json**). 

1.  For **Revision file type**, choose **.json** or **.yaml** as appropriate. 

1.  (Optional) In **Deployment description**, enter a description for your deployment. 

1. Choose **Create deployment**.

 You can monitor your deployment in **Deployment status**. After 100% of production traffic is routed to the replacement task set, you can choose **Terminate original task set** to immediately terminate the original task set. If you do not choose **Terminate original task set**, the original task set terminates after the duration you specified when you created your deployment group.
