What Kube-OVN is

Kube-OVN combines OVN and Open vSwitch with Kubernetes to orchestrate cloud-native networks. It supports subnet management, static IP allocation, gateways, hybrid underlay and overlay networks, VPC features, QoS, ACLs, and traffic mirroring. VPC networks can provide tenants with separate address spaces and networking resources. For Kubernetes environments using KubeVirt, it supports virtual machine live migration without network interruption. The project also documents integrations with Cilium, MetalLB, OpenStack, Submariner, and OVN interconnect; Cilium chaining combines Kube-OVN network abstractions with Cilium eBPF monitoring and security capabilities. Kube-OVN runs on x86_64 and arm64, and its documentation provides one-click installation scripts. The project says it has been validated in production with clusters of thousands of nodes and hundreds of thousands of pods. It is free, open source under Apache-2.0, and deployed on-premises with a centralized control plane. The project advises against using it with OpenShift, public-cloud managed Kubernetes, or when an all-in-one networking, ingress, service mesh, and observability stack is required.

Good

  • Supports KubeVirt live migration without network interruption.
  • Provides tenant VPCs with separate address spaces.
  • Includes QoS, ACLs, gateways, and traffic mirroring.
  • Runs on x86_64 and arm64.
  • Free under the Apache-2.0 license.

Watch out

  • Not advised for OpenShift or managed public-cloud Kubernetes.
  • Not an all-in-one ingress, service mesh, and observability stack.

Who it suits

Kube-OVN suits Kubernetes environments that need KubeVirt support or multi-tenant networking. It may also fit teams seeking on-premises networking with VPCs and policy segmentation.

Verdict

Kube-OVN brings a broad set of network orchestration capabilities to Kubernetes, including tenant VPCs and KubeVirt migration support. Check its stated deployment limitations before choosing it for a managed Kubernetes environment or an all-in-one stack.
