## Tagging an instance as part of a deployment group does not automatically deploy your application to the new instance
<a name="troubleshooting-adding-instance-to-group"></a>

CodeDeploy does not automatically deploy your application to a newly tagged instance. You must create a new deployment in the deployment group.

You can use CodeDeploy to enable automatic deployments to new EC2 instances in Amazon EC2 Auto Scaling groups. For more information, see [Integrating CodeDeploy with Amazon EC2 Auto Scaling](integrations-aws-auto-scaling.md).
