Kube-OVN is a CNCF Sandbox CNI plugin that integrates OVN-based network virtualization with Kubernetes, providing an advanced container network fabric. It offers enterprise features such as multi-tenant VPCs, namespaced subnets, underlay/VLAN networking, static IPs, and multi-cluster connectivity.
Use cases
- give each kubernetes namespace its own subnet with static pod IPs
- run multi-tenant kubernetes networking with isolated VPCs and overlapping IP spaces
- connect kubernetes pods directly to the physical network via VLAN/underlay networking
- live migrate KubeVirt virtual machines without network interruption
- enforce kubernetes NetworkPolicy with high-performance OVN ACLs
- run ipv4/ipv6 dual-stack pods in kubernetes
- connect multiple kubernetes clusters into one L3 network
- use kube-ovn as a secondary CNI alongside cilium or calico
When to choose
- you need enterprise-grade SDN features in Kubernetes like VPCs, NAT/EIP, and subnet isolation
- you require static IP allocation or dual-stack networking for workloads
- you run KubeVirt VMs and need seamless live migration
- you want underlay/VLAN connectivity or multi-cluster L3 networking
When to avoid
- you need only a simple CNI with minimal overhead
- your team has no experience with OVN/Open vSwitch and wants a simpler setup
- you run Kubernetes on platforms without Linux node support (no Windows/arm32)
