Using Multus CNI in K3S

By default, K3S will run with flannel as the CNI and use custom directories to store CNI plugin binaries and config files(You can inspect the kubelet args K3S uses via journalctl -u k3s|grep cni-conf-dir). So you need to configure that properly When deploying Multus CNI.

For example given the official Multus manifests in https://github.com/intel/multus-cni/blob/36f2fd64e0965e639a0f1d17ab754f0130951aba/images/multus-daemonset.yml, the following changes are needed:

volumes:
 - name: cni

    else
      echo "${1}${secret}"
