Create sriov-nad.yaml with below contents:
| apiVersion: "k8s.cni.cncf.io/v1" kind: NetworkAttachmentDefinition metadata: name: sriov-eno2 annotations: k8s.v1.cni.cncf.io/resourceName: intel.com/intel_sriov_700 spec: config: '{ "type": "sriov", "ipam": { "type": "host-local", "subnet": "10.56.206.0/24", "routes": [ { "dst": "0.0.0.0/0" } ], "gateway": "10.56.206.1" } }' |
|---|
Apply to K8s with sriov-eno2 NetworkAttachmentDefinition:
| cat sriov-nad.yaml | kubectl apply -f - |
|---|
(2) Create Pod to request SRIOV interface
Create sriov-eno2-pod.yaml with below contents:
| apiVersion: v1 kind: Pod metadata: name: pod-case-01 annotations: k8s.v1.cni.cncf.io/networks: sriov-eno2 spec: containers: - name: test-pod image: docker.io/centos/tools:latest command: - /sbin/init resources: requests: intel.com/intel_sriov_700: '1' limits: intel.com/intel_sriov_700: '1' |
|---|
Create the a pod:
| cat sriov-eno2-pod.yaml | kubectl apply -f - |
|---|
Verify the SRIOV interface in the created pod (e.g. net1 as below):
kubectl exec -i pod-case-01 ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever 3: eth0@if108: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc noqueue state UP group default link/ether a2:e7:69:81:c7:3e brd ff:ff:ff:ff:ff:ff link-netnsid 0 inet 10.244.0.162/24 scope global eth0 valid_lft forever preferred_lft forever 36: net1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether da:e9:13:20:f5:98 brd ff:ff:ff:ff:ff:ff inet 10.56.206.6/24 scope global net1 valid_lft forever preferred_lft forever |
