Facts

Purpose

Spiderpool is an underlay and RDMA networking solution for Kubernetes on bare metal, virtual machines, and public clouds.spidernet-io.github.io · 4 Oct 2026

IP address management

Its CRD-based IPAM supports dual-stack networking, shared and exclusive pools, and static IP addresses for stateful applications.spidernet-io.github.io · 4 Oct 2026

CNI support

Spiderpool works with Macvlan, IPvlan, and SR-IOV, and its IPAM can also be used with compatible CNIs such as Calico and Weave.spidernet-io.github.io · 4 Oct 2026

Multiple interfaces

Pods can use multiple underlay interfaces or a combination of underlay and overlay interfaces, with policy routing managed across interfaces.spidernet-io.github.io · 4 Oct 2026

Connectivity

The project documents Pod-to-host connectivity, IP conflict detection, gateway reachability checks, and service access through kube-proxy or an eBPF-based replacement.spidernet-io.github.io · 4 Oct 2026

RDMA

Spiderpool supports RDMA using RoCE and InfiniBand, with devices available to Pods in shared or exclusive mode.spidernet-io.github.io · 4 Oct 2026

Use cases

The project identifies storage, middleware, observability, AI training, latency-sensitive workloads, and applications needing separate network bandwidth as use cases.spidernet-io.github.io · 4 Oct 2026

Deployment requirements

Documented node architectures are x86-64 and arm64; the SpiderSubnet feature requires Kubernetes v1.21 or later.spidernet-io.github.io · 4 Oct 2026
