Configure a trigger

Container Registry provides the trigger feature for image repositories. If you create a trigger for an image repository, a notification is pushed to you when an image is built. This facilitates the deployment of images for applications. If you create a trigger for a container service, the applications on the container service automatically pull and redeploy the new images that are built on the container service. This topic describes how to configure a trigger.

Security rules on trigger usage
