Kubean is a production-ready cluster lifecycle management toolchain written in Go that builds upon kubespray and other cluster lifecycle management engines. It is designated as a Cloud Native Computing Foundation sandbox project and provides declarative APIs for deploying and managing Kubernetes clusters at scale.
The project emphasizes simplicity through its declarative API approach to cluster lifecycle operations. A key feature is offline support, with offline packages including operating system packages, container images, and binaries released alongside each version, eliminating the need to gather resources from external sources during deployment. The toolchain supports multi-architecture delivery across AMD and ARM processors with common Linux distributions, and includes support for specialized architectures such as Kunpeng processors running Kylin operating systems. Expandability is built into the design, allowing custom actions to be added to clusters without requiring modifications to the underlying Kubespray implementation.
The repository maintains broad Kubernetes version compatibility, supporting ranges from v1.29 through v1.35 across different Kubean versions. For instance, Kubean v0.34.2 supports Kubernetes v1.33 through v1.35 with v1.34.7 as the default version. The project provides multiple deployment pathways including interactive tutorials on Killercoda, guided installation through KubeStellar Console with step-by-step instructions and validation, and local installation options using declarative YAML configurations.
The repository is classified across multiple infrastructure and cloud-native domains including cluster automation, deployment management, resource scheduling, pod management, and microservices deployment. It has achieved Kubernetes conformance certification and maintains code quality standards tracked through continuous integration workflows, code coverage metrics, and CNCF best practices badges.
