# KusionStack Rollout

## Overview

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](https://github.com/kubernetes/enhancements/tree/master/keps/sig-multicluster/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.

## Key Features

- 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](https://gateway-api.sigs.k8s.io)

- Extends rollout progress with webhook

## Quick Start

See [Getting Started Guide](docs/en/quick_start.md) to walk through creating and then updating the rollout in local kind cluster.
