对EKS集群中的即时索赔卷未绑定的节点

Question

我创建了一个带有6个节点的EKS集群。在每个节点中，使用启动模板附加EFS文件系统，并在文件系统中创建一个文件，所有工作节点也可以访问文件。通过SSH我检查了这个操作。

但是在安装csi驱动程序和在ek中创建存储类之后，尝试创建一个带有动态pvc声明的测试应用程序时，集群告诉我，

聚氯乙烯软罐：

Normal  ExternalProvisioning    2 hours persistentvolume-controller waiting for a volume to be created, either by external provisioner "efs.csi.aws.com" or manually created by system administrator

应用程序Pod:

FailedScheduling    2 hours default-scheduler   0/6 nodes are available: 6 pod has unbound immediate PersistentVolumeClaims.

我怎样才能解决efs的问题？请给我一些指导。我在这里呆了将近一个月。

Answer 1

根据PVC状态待定，没有提供程序能够创建卷。你试过创建一个PersistentVolume吗？

apiVersion: v1
kind: PersistentVolume
metadata:
  name: test-volume
spec:
  storageClassName: eks-sc-efs
  capacity:
    storage: 5Gi
  accessModes:
  - ReadWriteOnce

描述对象并查看是否有其他错误。另外，确保安装了CSI驱动程序。我从AWS https://docs.aws.amazon.com/eks/latest/userguide/efs-csi.html找到了这个文档
