Creating an extension association for a custom Amazon AppConfig extension

To create an extension, or configure an Amazon authored extension, you define the action points that invoke an extension when a specific Amazon AppConfig resource is used. For example, you can choose to run the Amazon AppConfig deployment events to Amazon SNS extension and receive notifications on an Amazon SNS topic anytime a configuration deployment is started for a specific application. Defining which action points invoke an extension for a specific Amazon AppConfig resource is called an extension association. An extension association is a specified relationship between an extension and an Amazon AppConfig resource, such as an application or a configuration profile.

A single Amazon AppConfig application can include multiple environments and configuration profiles. If you associate an extension to an application or an environment, Amazon AppConfig invokes the extension for any workflows that relate to the application or environment resources, if applicable.

For example, say you have an Amazon AppConfig application called MobileApps that includes a configuration profile called AccessList. And say the MobileApps application includes Beta, Integration, and Production environments. You create an extension association for the Amazon authored Amazon SNS notification extension and associate the extension to the MobileApps application. The Amazon SNS notification extension is invoked anytime the configuration is deployed for the application to any of the three environments.

Use the following procedures to create an Amazon AppConfig extension association by using the Amazon AppConfig console.
