+Kube-OVN
+===========
+Kube-OVN integrates the OVN-based Network Virtualization with Kubernetes. It offers an advanced Container Network Fabric for Enterprises.
+
+For more information please check [Kube-OVN documentation](https://github.com/alauda/kube-ovn)
+
+## How to use it
+
+Enable kube-ovn in `group_vars/k8s-cluster/k8s-cluster.yml`
+```
+...
+kube_network_plugin: kube-ovn
+...
+```
+
+## Verifying kube-ovn install
+
+Kube-OVN run ovn and controller in `kube-ovn` namespace
+
+* Check the status of kube-ovn pods
+
+```
+# From the CLI
+kubectl get pod -n kube-ovn
+
+# Output
+NAME                                   READY   STATUS    RESTARTS   AGE
