Request help to start sriov-device-plugin pod

[murali509]

I am running single node kubernetes cluster and I have deployed sriov-network-operator https://github.com/k8snetworkplumbingwg/sriov-network-operator)
Observed that node has got below label:

kubectl get nodes --show-labels
NAME STATUS ROLES AGE VERSION LABELS
dauk-mrl-k-host04 Ready control-plane 146d v1.30.4 beta.kubernetes.io/arch=amd64,beta.kubernetes.io/os=linux,custom.os=linux,kubernetes.io/arch=amd64,kubernetes.io/hostname=dauk-mrl-k-host04,kubernetes.io/os=linux,node-role.kubernetes.io/control-plane=,node.kubernetes.io/exclude-from-external-load-balancers=,nodePool=withSriov,sriovnetwork.openshift.io/device-plugin=Disabled

And also observed that daemonset sriov-device-plugin under namespace sriov-network-operator is created as per below output:

k get all -n sriov-network-operator
NAME READY STATUS RESTARTS AGE
pod/sriov-network-config-daemon-vff7d 1/1 Running 0 3h30m

I see sriov-device-plugin pod is not deployed. Is it because of the sriovnetwork.openshift.io/device-plugin=Disabled on the node?
If yes, please let me know how to deploy sriov-device-plugin pod? This is community kubernetes node deployed using kubespray.

hi @murali509 , the sriov-device-plugin is deployed by the operator after the user creates SriovNetworkNodePolicy.
This way the operator deploys the device-plugin on the SR-IOV configured nodes only. Can you try creating some policies?

Thanks a lot. After creating SriovNetworkNodePolicy, I see device-plugin is started.
