Rollouts

Introduction

Kruise Rollouts is a Bypass component which provides advanced deployment capabilities such as canary, traffic routing, and progressive delivery features, for a series of Kubernetes workloads, such as Deployment and CloneSet.

Why Kruise Rollouts?

Functionality：
- Support multi-batch delivery for Deployment/CloneSet.
- Support Nginx/ALB/Istio traffic routing control during rollout.
Flexibility:
- Support scaling up/down to workloads during rollout.
- Can be applied to newly-created or existing workload objects directly;
- Can be ridden out of at any time when you needn't it without consideration of unavailable workloads and traffic problems.
- Can cooperate with other native/third-part Kubernetes controllers/operators, such as HPA and WorkloadSpread.
Non-Invasion:
- Does not invade native workload controllers.
- Does not replace user-defined workload and traffic configurations.
Extensibility:
- Easily extend to other traffic routing types, or workload types via plugin codes.
Easy-integration:
- Easily integrate with classic or GitOps-style Kubernetes-based PaaS.

The global idea is from both OpenKruise and KubeVela communities, and the basic code of rollout is inherited from the KubeVela Rollout.
This project is maintained by both contributors from OpenKruise and KubeVela.
