我正在 AWS EKS 中的 Kubernetes 上部署 Elasticsearch 集群。我的规格是：

apiVersion: elasticsearch.k8s.elastic.co/v1
kind: Elasticsearch
metadata:
  name: es
spec:
  version: 7.14.0
  nodeSets:
  - name: node
    count: 2
    config:
      node.store.allow_mmap: false
    volumeClaimTemplates:
    - metadata:
        name: elasticsearch-data
      spec:
        accessModes:
          - ReadWriteOnce
        storageClassName: ebs-sc
        resources:
          requests:
            storage: 1024Gi

部署时出现此错误：

for: "es.yml": admission webhook "elastic-es-validation-v1.k8s.elastic.co" denied the request: Elasticsearch.elasticsearch.k8s.elastic.co "es" is invalid: spec.nodeSet[0].volumeClaimTemplates: Invalid value: []v1.PersistentVolumeClaim{v1.PersistentVolumeClaim{TypeMeta:v1.TypeMeta{Kind:"", APIVersion:""}, ObjectMeta:v1.ObjectMeta{Name:"elasticsearch-data", GenerateName:"", Namespace:"", SelfLink:"", UID:"", ResourceVersion:"", Generation:0, CreationTimestamp:time.Date(1, time.January, 1, 0, 0, 0, 0, time.UTC), DeletionTimestamp:<nil>, DeletionGracePeriodSeconds:(*int64)(nil), Labels:map[string]string(nil), Annotations:map[string]string(nil), OwnerReferences:[]v1.OwnerReference(nil), Finalizers:[]string(nil), ClusterName:"", ManagedFields:[]v1.ManagedFieldsEntry(nil)}, Spec:v1.PersistentVolumeClaimSpec{AccessModes:[]v1.PersistentVolumeAccessMode{"ReadWriteOnce"}, Selector:(*v1.LabelSelector)(nil), Resources:v1.ResourceRequirements{Limits:v1.ResourceList(nil), Requests:v1.ResourceList{"storage":resource.Quantity{i:resource.int64Amount{value:1099511627776, scale:0}, d:resource.infDecAmount{Dec:(*inf.Dec)(nil)}, s:"", Format:"BinarySI"}}}, VolumeName:"", StorageClassName:(*string)(0xc000cd2600), VolumeMode:(*v1.PersistentVolumeMode)(nil), DataSource:(*v1.TypedLocalObjectReference)(nil)}, Status:v1.PersistentVolumeClaimStatus{Phase:"", AccessModes:[]v1.PersistentVolumeAccessMode(nil), Capacity:v1.ResourceList(nil), Conditions:[]v1.PersistentVolumeClaimCondition(nil)}}}: volume claim templates can only have their storage requests increased, if the storage class allows volume expansion. Any other change is forbidden

该规范包括volumeClaimTemplates用于声明持久存储的内容。我不明白为什么它说volume claim templates can only have their storage requests increased, if the storage class allows volume expansion。

我检查了 PVC 是空的：

$ kubectl get pvc
No resources found in default namespace.

我有以下存储类规范：

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: ebs-sc
provisioner: ebs.csi.aws.com
allowVolumeExpansion: true
volumeBindingMode: WaitForFirstConsumer

您的存储类需要允许卷扩展：

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: ebs-sc
provisioner: ebs.csi.aws.com
allowVolumeExpansion: true
parameters:
  type: gp3
reclaimPolicy: Delete
volumeBindingMode: WaitForFirstConsumer
