Spiderpool
Spiderpool is a free, open-source Kubernetes networking solution for underlay networking and RDMA on bare metal, virtual machines, and public clouds. Its CRD-based IPAM handles dual-stack networks, shared or exclusive address pools, and static addresses for stateful applications. The project supports Macvlan, IPvlan, and SR-IOV, while its IPAM can pair with compatible CNIs such as Calico and Weave. Pods may use multiple underlay interfaces or combine underlay and overlay interfaces, with policy routing across them. Documented connectivity includes Pod-to-host access, conflict detection, gateway checks, and service access through kube-proxy or an eBPF replacement. RDMA works with RoCE and InfiniBand in shared or exclusive device modes. Use cases include storage, middleware, observability, AI training, latency-sensitive workloads, and separate bandwidth needs. It supports AMD64 and ARM64 nodes, with SpiderSubnet requiring Kubernetes 1.21 or later. Spiderpool is Apache 2.0 licensed and a CNCF sandbox project.
