kubernetes - 无法使用 StorageClass“慢”配置卷：无法获取 GCE GCECloudProvider 并出现错误

问题描述

我正在尝试从 GKE 中安装 Redis 集群（StatefulSet），并且在获取 pvc 时我得到了

Events:
  Type       Reason              Age   From                         Message
  ----       ------              ----  ----                         -------
  Warning    ProvisioningFailed  10s   persistentvolume-controller  Failed to provision volume with StorageClass "slow": Failed to get GCE GCECloudProvider with error <nil>

已经在文件 /etc/kubernetes/manifests/kube-controller-manager.yaml 和 sudo vi /etc/kubernetes/manifests/kube-apiserver.yaml 上添加了“--cloud-provider=gce”。重新启动但还是一样。任何人都可以帮助我吗？让 k8s 在 GCP 上工作的诀窍是什么？

我的清单取自这里：

解决方案

请验证您的“StorageClass：慢”，似乎存在缩进问题（从reclaimPolicy开始）

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: slow
provisioner: kubernetes.io/gce-pd
parameters:
  type: pd-standard
  replication-type: none
  zone: "us-west2-a"
reclaimPolicy: Retain

＃ 更新：

  1. 请添加--cloud-provider=gce到：kube-apiserver.yaml、kube-controller-manager.yaml、KUBELET_KUBECONFIG_ARGS。您还可以启用enable-admission-plugins= DefaultStorageClass

  2. 在“云 API 访问范围”权限中验证您的“VM 实例详细信息”权限。

  3. 验证您的存储类 pv 和 pvc 是否正常工作。

  kind: StorageClass
    apiVersion: storage.k8s.io/v1beta1
    metadata:
      name: slow
      annotations:
        storageclass.beta.kubernetes.io/is-default-class: "true" 
    provisioner: kubernetes.io/gce-pd
    parameters:
      type: pd-standard      

  apiVersion: v1
    kind: PersistentVolumeClaim
    metadata:
     name: pvc-test
    spec:
     accessModes:
      - ReadOnlyMany
     storageClassName: slow
     resources:
       requests:
         storage: 1Gi
