Karmada vs KubeClipper

Karmada manages cloud-native applications across multiple Kubernetes clusters and clouds without requiring changes to the applications. It supports public and private cloud, on-premises, edge, and self-built environments that meet Kubernetes specifications. Cluster connections can use Push mode through a Kubernetes API server or Pull mode through an in-cluster agent. Scheduling policies cover cluster affinity, taints and tolerations, topology spread, and replicated or divided placement. OverridePolicy allows per-cluster changes to images, arguments, commands, and plain-text configuration. Karmada can move replicas after a cluster failure, including migration that avoids service replicas dropping to zero. Through karmada-apiserver, teams can create, update, delete, and query resources across member clusters. Its components export Prometheus metrics; integrations described include Submariner networking and ErieCanal service governance. Installation options include CLI tools, Helm, an operator, binaries, or source. The CLI initialization requires escalated privileges to store shared configuration under /etc/karmada by default. Karmada is open source and free, with customer-managed control plane; it manages clusters but does not provision them.

KubeClipper is a free, open-source service for managing Kubernetes clusters on an organization’s own infrastructure. Its web interface, APIs, and kcctl command-line tool support cluster deployment and lifecycle operations across cloud, hypervisor, and bare-metal environments. Users can create, delete, upgrade, back up, restore, and scale clusters, and register clusters built elsewhere. Deployment can be online, offline, or through a proxy; a graphical wizard helps set up clusters and required plugins. Node tools include automatic registration, information collection, and a terminal. Access controls include role-based and custom permissions, with OIDC login for external users. Backups cover etcd data and Kubernetes resource objects, using filesystem or S3 storage such as NFS or MinIO; files produced by resources and files on persistent volumes are outside that backup scope. The project lists x86/64 and arm64 support and extensible management of CRI, CNI, CSI, and CRD components. Worker-node addition and removal are the currently supported node changes.
