This topic describes the features of the progressive-delivery-tool component and lists the latest changes to this component.


Alibaba Cloud Container Service for Kubernetes (ACK) provides the progressive-delivery-tool component to support canary releases of your applications. When you deploy a canary version of an application next to the stable production version in a canary release, you can manage the network traffic that is incrementally routed to the canary version. This allows you to progressively release the new version for all users and minimize the potential risks of the new version within a limited scope. If the canary version fails specified health checks, quick rollback is supported.
