Tutorial: Create a Bond Interface and Connect it to a Node Interface

Use Node Network Configuration Policy to configure a new bond interface bond0 with slaves eth1 and eth2.

Requirements

Before we start, please make sure that you have your Kubernetes/OpenShift cluster ready. In order to do that, you can follow the guides of deployment on local cluster or your arbitrary cluster.

Configure bond

All you have to do in order to create the bond on all nodes across cluster is to apply the following policy:

cat <<EOF | ./kubevirtci/cluster-up/kubectl.sh create -f -
apiVersion: nmstate.io/v1alpha1
kind: NodeNetworkConfigurationPolicy
metadata:
  name: bond0-eth1-eth2-policy
spec:
  desiredState:
    interfaces:
    - name: bond0
      type: bond
      state: up
      ipv4:
        address:
        - ip: 10.10.10.10
          prefix-length: 24
        enabled: true
      link-aggregation:
        mode: balance-rr
        options:
          miimon: '140'
        slaves:
        - eth1
        - eth2
EOF

You can also remove the bond with following:

cat <<EOF | kubectl create -f -
apiVersion: nmstate.io/v1alpha1
kind: NodeNetworkConfigurationPolicy
metadata:
  name: bond0-eth1-eth2-policy
spec:
  desiredState:
    interfaces:
      - name: bond0
        type: bond
        state: absent
EOF
