Installation

Kube-OVN includes two parts:

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

To install

  1. 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

  2. Install native OVS and OVN components:

    kubectl apply -f https://raw.githubusercontent.com/alauda/kube-ovn/v0.3.0/yamls/ovn.yaml

  3. Install the Kube-OVN Controller and CNI plugins:

    kubectl apply -f https://raw.githubusercontent.com/alauda/kube-ovn/v0.3.0/yamls/kube-ovn.yaml

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

For high-available ovn db, see high available

More Configuration

Controller Configuration

```bash
--default-cidr: Default CIDR for Namespaces with no logical switch annotation, default: 10.16.0.0/16
--node-switch-cidr: The CIDR for the Node switch. Default: 100.64.0.0/16
```

To uninstall

  1. Remove Kubernetes resources:

    wget https://raw.githubusercontent.com/alauda/kube-ovn/master/dist/images/cleanup.sh
bash cleanup.sh

  2. Delete OVN/OVS DB and config files on every Node:

    rm -rf /var/run/openvswitch
rm -rf /etc/origin/openvswitch/
rm -rf /etc/openvswitch

  3. Reboot the Node to remove ipset/iptables rules and nics.
