Option 1: Use Storage Class

• Download static provision storage class and PVC file.

• Edit the EXISTING_LUSTRE_FS_NAME and EXISTING_LUSTRE_IP_ADDRESS in storage class.

• Create storage class and PVC

kubectl create -f storageclass_existing_lustre.yaml
kubectl create -f pvc_storageclass.yaml

 

Option 2: Use PV

• Download PV file and PVC file

• Edit the EXISTING_LUSTRE_FS_NAME, EXISTING_LUSTRE_IP_ADDRESS and UNIQUE_IDENTIFIER_VOLUME_ID in pv.

• Create PV and PVC.

kubectl create -f pv.yaml
kubectl create -f pvc_pv.yaml

 

Use the Volume

• Make sure pvc is created and in Bound status after a while

kubectl describe pvc pvc-lustre

• Download demo pod echo date

• Create the POD with PVC mount

kubectl create -f pod_echo_date.yaml

• Execute df -h command in the container and you can see the volume is mounted

$ kubectl exec -it lustre-echo-date -- df -h
