    Container Service for Kubernetes:Knative version release notes

    Last Updated:Mar 26, 2026

    Knative is an open-source, Kubernetes-based serverless framework that delivers a cloud-native and cross-platform orchestration standard for serverless applications. Knative Serving is a fully managed, O&M-free core component of Knative that handles serverless workloads, including application deployment and version management. When no traffic is processed, the pod count scales to zero. This topic describes the release notes for Knative Serving.

    Components

    ACK Knative is fully compatible with open-source Knative and integrates comprehensively with Alibaba Cloud services. The capabilities of ACK Knative are enhanced to offer more extensive product solutions.

    Knative consists of three core components:

    Component Description
    Knative Serving Manages serverless workloads. Supports serverless deployment, version management, canary releases, and pod autoscaling based on resource requests. Scales to zero when no traffic is received.
    Knative Eventing Manages events. Lets you interface with external event sources, register and subscribe to events, and filter events. Decouples event producers from event consumers.
    Knative Functions Creates, builds, and deploys Knative Services. Deploy stateless, event-driven functions as Knative Services to a Kubernetes cluster without deep knowledge of the underlying stack (Kubernetes, containers, or Knative).
