KubeFleet
KubeFleet is a sandbox project of the Cloud Native Computing Foundation (CNCF) that works on any Kubernetes cluster.
We are working towards the vision to enable you treat your Kubernetes clusters as a flexible container runtime environment where workloads can run anywhere within your fleet.
What is KubeFleet?
KubeFleet contains a set of Kubernetes controllers and CRDs which provide an advanced cloud-native solution for multi-cluster application management.
Use KubeFleet to schedule workloads intelligently, roll out changes progressively, and perform administrative tasks easily, across a group of Kubernetes clusters in any location.
Quickstart
Key benefits and capabilities
Centralized policy-driven fleet governance
KubeFleet utilizes a hub-spoke architecture that creates a single control plane for the fleet. It allows fleet administrators to apply uniform cloud native policies on every member cluster, whether they reside in public clouds, private data centers, or edge locations. This greatly simplifies governance across large, geographically distributed fleets spanning hybrid and multi-cloud environments.
Progressive Rollouts with Safeguards
KubeFleet provides a cloud native progressive rollout plans sequence updates across the entire fleet with health verification at each step. The application owner can pause or rollback to any previous versions when they observe failures, limiting blast radius. This keeps multi-cluster application deployments reliable and predictable spanning edge, on-premises, and cloud environments.
Powerful Multi-Cluster Scheduling
KubeFleet's scheduler evaluates member cluster properties, available capacity, and declarative placement policies to select optimal destinations for workloads. It supports cluster affinity and anti-affinity rules, topology spread constraints to distribute workloads across failure domains, and resource-based placement to ensure sufficient compute, memory, and storage. The scheduler continuously reconciles as fleet conditions change, automatically adapting to cluster additions, removals, or capacity shifts across edge, on-premises, and cloud environments.
