Installation

Kube-OVN includes two parts:

  • Native OVS and OVN components
  • Controller and CNI plugins that integrate OVN with Kubernetes

To install

  • Add the following label to the Node which will host the OVN DB and the OVN Control Plane:

kubectl label node <Node on which to deploy OVN DB> kube-ovn/role=master

  • Install native OVS and OVN components:

kubectl apply -f https://raw.githubusercontent.com/alauda/kube-ovn/v0.4.0/yamls/ovn.yaml

  • Install the Kube-OVN Controller and CNI plugins:

kubectl apply -f https://raw.githubusercontent.com/alauda/kube-ovn/v0.4.0/yamls/kube-ovn.yaml

That's all! You can now create some pods and test connectivity.
