在AKS中使用正确的区域信息配置PVC

Question

我正在使用Velero执行从GCP到Azure的群集备份和恢复

由于两个GCP提供商的区域/区域不同，k8s中的持久化卷具有NodeAffinity，其区域和区域选择器与Azure节点上的lables不匹配。

例如，节点GCP上的以下标签

failure-domain.beta.kubernetes.io/region=australia-southeast1
failure-domain.beta.kubernetes.io/zone=australia-southeast1-a

在Azure上

failure-domain.beta.kubernetes.io/region=australiaeast
failure-domain.beta.kubernetes.io/zone=1

因此，我尝试在Azure中创建一个storage-class，如下所示：

kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
  name: fast-azure
provisioner: kubernetes.io/azure-disk
allowVolumeExpansion: true
parameters:
  cachingmode: ReadOnly
  kind: Managed
  storageaccounttype: Premium_LRS
volumeBindingMode: WaitForFirstConsumer
allowedTopologies:
- matchLabelExpressions:
  - key: failure-domain.beta.kubernetes.io/zone
    values:
    - "1"
  - key: failure-domain.beta.kubernetes.io/region
    values:
    - australiaeast

但是，当我尝试使用这个存储类创建PVC时，我得到了以下错误：

arning  ProvisioningFailed    1s (x6 over 29s)   persistentvolume-controller  Failed to provision volume with StorageClass "fast-azure": compute.DisksClient#CreateOrUpdate: Failure sending request: StatusCode=400 -- Original Error: Code="InvalidAvailabilityZone" Message="The zone(s) '' for resource 'Microsoft.Compute/disks/kubernetes-dynamic-pvc-105101ea-2c58-4a5a-8eeb-386c7489b782' is not supported. The supported zones for location 'australiaeast' are '1,2,3'"

看起来它正在读取一个空白的'‘区域名称。为Azure编写此storageclass的正确方法是什么？

尝试以下操作。这对我很管用。

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: azure-disk
parameters:
  cachingmode: None
  kind: Managed
  zoned: "true"
  storageaccounttype: Standard_LRS
provisioner: kubernetes.io/azure-disk
allowedTopologies:
- matchLabelExpressions:
  - key: failure-domain.beta.kubernetes.io/zone
    values:
    - australiaeast-1
