StorageClass的参数availabilityZone 无效

[simonwu-os]

需要创建华东-上海二的可用区一的云硬盘。
设置如下:
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: evs-ssd
provisioner: evs.csi.huaweicloud.com
parameters:
csi.storage.k8s.io/fstype: ext4
type: SSD # 云硬盘类型（SSD/SAS/GPSSD）
availabilityZone: cn-east-2a
reclaimPolicy: Delete
allowVolumeExpansion: true
volumeBindingMode: WaitForFirstConsumer ##| Immediate

第一次，能够在可用区一创建云硬盘。删除pvc之后，后面多次创建都是华东-上海二的可用区2，不是可用区1.
感觉availabilityZone 参数无效.

find the docs. It uses availability.

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: evs-ssd
provisioner: evs.csi.huaweicloud.com
parameters:
csi.storage.k8s.io/fstype: ext4
type: SSD # 云硬盘类型（SSD/SAS/GPSSD）
availability: cn-east-2a # 必须与节点所在AZ一致！
scsi: "true"
reclaimPolicy: Delete
allowVolumeExpansion: true
volumeBindingMode: WaitForFirstConsumer

It works now.

推荐使用topology特性，参考如下脚本创建SC，当创建PVC的时候会根据容器所在的可用区创建EVS

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: evs-sc
provisioner: evs.csi.huaweicloud.com
volumeBindingMode: WaitForFirstConsumer
allowedTopologies:
  - matchLabelExpressions:
      - key: topology.evs.csi.huaweicloud.com/zone
        values:
          - cn-east-2a
          - cn-east-2b
          - cn-east-2c
parameters:
  type: SSD
