无法使用StorageClass"slow"调配卷:无法获得GCE GCECloudProvider，错误为< nil>.

问题描述

我正在尝试从GKE中安装Redis群集(StatefulSet)，并且在获取pvc时我已经有了

I'm trying to install Redis cluster (StatefulSet) out of GKE and when getting pvc I've got

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中添加了"--cloud-provider = gce".重新启动，但仍然相同.谁能帮我吗?使k8在GCP上运行的诀窍是什么?

Already added "--cloud-provider=gce" on files /etc/kubernetes/manifests/kube-controller-manager.yaml and sudo vi /etc/kubernetes/manifests/kube-apiserver.yaml. Restarted but still the same.Can anyone help me please? What's the trick for making k8s work on GCP?

推荐答案

请验证您的"StorageClass:缓慢"，似乎存在缩进问题(从reclaimPolicy开始)

Please verify your "StorageClass: slow", it seems there is an indentation problem (starting with reclaimPolicy)

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

1. Please add --cloud-provider=gce into: kube-apiserver.yaml, kube-controller-manager.yaml, KUBELET_KUBECONFIG_ARGS. You can also enable enable-admission-plugins=DefaultStorageClass

在"Cloud API访问范围"权限中验证您的"VM实例详细信息" .

Verify in your "VM instance details" permissiosn in "Cloud API access scopes" permissions.

验证存储类pv和pvc是否正常运行.

Verify if your storage class pv and pvc are working properly.
