KusionStack Rollout is a progressive delivery controller that automates the release process for applications running on Kubernetes Clusterset. It provides several delivery strategies such as Canary release, Blue/Green mirroring, A/B testing to reduce the risk of introducing a new version in production. It can also integrates with GatewayAPI, leveraging its traffic shaping ablibities to gradually shift traffic to the new version.

The terminology clusterset is defined in KEP-1645: Multi-Cluster Services API.

clusterset - A placeholder name for a group of clusters with a high degree of mutual trust and shared ownership that share services amongst themselves. Membership in a clusterset is symmetric and transitive. The set of member clusters are mutually aware, and agree about their collective association. Within a clusterset, namespace sameness applies and all namespaces with a given name are considered to be the same namespace. Implementations of this API are responsible for defining and tracking membership in a clusterset. The specific mechanism is out of scope of this proposal.

• Supports progressive delivery for Applications with multiple components cross Multi Clusters.
• Supports various kinds of workload, such as StatefulSet, CollaSet.
• Supports several delivery strategies, such as Canary release, Multi Batch, Blue/Green mirroring, A/B testing.
• Supports fine-grained traffic shifting with GatewayAPI
• Extends rollout progress with webhook

See Getting Started Guide to walk through creating and then updating the rollout in local kind cluster.
