KubeStellar

Multi-cluster configuration management for edge, multi-cloud, and hybrid cloud environments.

KubeStellar is a CNCF sandbox project that simplifies the deployment and configuration of applications across multiple Kubernetes clusters, providing a seamless single-cluster experience with the tools you already know.

Overview

KubeStellar enables you to manage multiple Kubernetes clusters as easily as managing. Whether you’re expanding from a single cluster or streamlining an existing multi-cluster setup, KubeStellar lets you define binding policies that automatically deploy and configure workloads across your fleet.

Key Features

Feature	Description
Declarative Multi-Cluster	Define what to deploy and where using familiar Kubernetes objects and binding policies
Single-Cluster Experience	Use your existing tools (kubectl, Helm, ArgoCD) without modification
Flexible Targeting	Deploy to clusters based on labels, location, capabilities, or custom criteria
Edge-Ready	Support for disconnected environments and intermittent connectivity
Status Aggregation	Unified view of workload status across all clusters
GitOps Compatible	Native integration with ArgoCD and other GitOps tools

Why Multi-Cluster?

Organizations adopt multi-cluster architectures for:

Environment separation - Development, staging, and production isolation
Team isolation - Dedicated clusters for different groups or departments
Compliance - Meeting security and data governance requirements
Resilience - High availability across regions and clouds
Edge computing - Running workloads close to users or data sources
