K8s动态卷配置: claim.Spec.Selector不支持AWS上的动态配置

Question

这是我的存储类配置

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  annotations:
    storageclass.kubernetes.io/is-default-class: "false"
  name: gp2
provisioner: kubernetes.io/aws-ebs
parameters:
  type: gp2
  fsType: ext4
reclaimPolicy: Delete
volumeBindingMode: Immediate
allowVolumeExpansion: true

并且持久卷是用AWS ebs创建的。

部署时，持久性卷声明失败，出现以下错误

ProvisioningFailed     persistentvolumeclaim/storage-fabric-orderer0   Failed to provision volume with StorageClass "gp2": claim.Spec.Selector is not supported for dynamic provisioning on AWS

供应程序已在我的集群中启动并运行。

由于不支持spec.selector，所以不应该在AWS中为动态配置设置PVC中的。你需要把这部分从PVC yaml中移除。

spec:
  selector:
    matchLabels:
      app.kubernetes.io/component: {{ .Values.dlt.component }}
      type: storage
      fabric/organization: {{ .Values.dlt.organization }}
      replica-index: {{ .Values.dlt.organizationIndex | print | toJson }}

来自文档。

注意:目前，具有非空选择器的PVC不能动态地为其提供PV。
