In their own words
Clusternet
Clusternet is a free, open-source add-on for managing Kubernetes clusters across public and private cloud, hybrid, on-premises, and edge environments. It lets operators manage member clusters from a parent cluster and access them as though they were local. It deploys Kubernetes resources, custom resource definitions, and Helm charts, with configuration tailored to individual clusters. Application scheduling can replicate workloads or distribute them by cluster weight or available capacity. Clusternet supports clusters from AWS, Google Cloud, Tencent Cloud, and Alibaba Cloud, along with on-premises systems, k3s, and edge clusters. It can discover and register clusters created by Cluster API and configure network tunnels for clusters in VPC networks, at the edge, or behind a firewall. Dynamic RBAC rules control access to managed clusters, and Submariner integration can connect workloads across clusters. Installation options include Helm and manual setup. A kubectl plugin is available through Krew or as a binary. Linux builds are listed for several architectures. Clusternet is a CNCF Sandbox project.
