kubernetes - 所需值 : must specify a volume type when statically provisioning PV

Question

尝试使用 GCP SSD 存储静态配置 PV。错误并显示以下消息:

The PersistentVolume "monitoring" is invalid: spec: Required value: must specify a volume type

重现步骤:

$ cat storage.yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: ssd
provisioner: kubernetes.io/gce-pd
parameters:
  type: pd-ssd
reclaimPolicy: Retain


$ kubectl apply -f storage.yaml
storageclass.storage.k8s.io/ssd created


$ cat pv.yaml
apiVersion: v1
kind: PersistentVolume
metadata:
  name: monitoring
spec:
  storageClassName: ssd
  capacity:
    storage: 50Gi
  persistentVolumeReclaimPolicy: Retain
  accessModes:
    - ReadWriteOnce


$ kubectl apply -f pv.yaml
The PersistentVolume "monitoring" is invalid: spec: Required value: must specify a volume type

如果使用供应商，您通常不会自己创建 PV。只需创建一个需要创建的存储类的 PVC，GKE 就会为您提供具有请求的存储大小和类型的 PV:

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: my-retain-ssd-storage
  namespace: default
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 50Gi
  storageClassName: ssd
