Goal
This Wiki describes the steps on how to deploy SRIOV device plugin in edge location node and how to use SRIOV device plugin in K8s podICN.
...
Implement details
The SRIOV network device plugin is Kubernetes device plugin for discovering and advertising SRIOV network virtual functions (VFs) in a Kubernetes host. and it provides below features:
...
(1) Install and probe Intel Nic kernel driver (e.g. iavf.ko for Intel Ethernet Controller 700 series etc.), it requires an input parameter for the interface (e.g. eno2) which the virtual functions will be created on.
(2) Enable virtual functions (VFs) on assigned interface.
Daemon set yaml:
(1) sriov-cni.yaml: deploy sriov cni plugin as daemon set in edge location node, the sriov cni plugin is responsible to create network interface based on allocated SRIOV VF when creating pod.
(2) sriovdp-daemonset.yaml: deploy sriov network device plugin as daemon set in edge location node. , the sriov network device plugin is responsible to discovery and advertise SRIOV VFs to K8s.
