CSI driver E2E usage example

1. create a pod with csi azuredisk driver mount on linux

Option#1: Azuredisk Dynamic Provisioning
  • Create an azuredisk CSI storage class
kubectl create -f https://raw.githubusercontent.com/kubernetes-sigs/azuredisk-csi-driver/master/deploy/example/storageclass-azuredisk-csi.yaml
  • Create an azuredisk CSI PVC
kubectl create -f https://raw.githubusercontent.com/kubernetes-sigs/azuredisk-csi-driver/master/deploy/example/pvc-azuredisk-csi.yaml
Option#2: Azuredisk Static Provisioning(use an existing azure disk)
  • Create an azuredisk CSI PV, download pv-azuredisk-csi.yaml file and edit diskName, diskURI in volumeAttributes
wget https://raw.githubusercontent.com/kubernetes-sigs/azuredisk-csi-driver/master/deploy/example/pv-azuredisk-csi.yaml
vi pv-azuredisk-csi.yaml
kubectl create -f pv-azuredisk-csi.yaml
  • Create an azuredisk CSI PVC which would be bound to the above PV
kubectl create -f https://raw.githubusercontent.com/kubernetes-sigs/azuredisk-csi-driver/master/deploy/example/pvc-azuredisk-csi-static.yaml

2. validate PVC status and create an nginx pod

  • make sure pvc is created and in Bound status finally
watch kubectl describe pvc pvc-azuredisk
  • create a pod with azuredisk CSI PVC
kubectl create -f https://raw.githubusercontent.com/kubernetes-sigs/azuredisk-csi-driver/master/deploy/example/nginx-pod-azuredisk.yaml

3. enter the pod container to do validation

  • watch the status of pod until its Status changed from Pending to Running and then enter the pod container
$ watch kubectl describe po nginx-azuredisk
$ kubectl exec -it nginx-azuredisk -- bash
Filesystem      Size  Used Avail Use% Mounted on
overlay          30G   15G   15G  52% /
...
/devhost/sdc        9.8G   37M  9.8G   1% /mnt/azuredisk
...

In the above example, there is a /mnt/azuredisk directory mounted as disk filesystem.
