安装EKS EFS CSI在Pod出现之前超时

Question

我在Kubernetes版本1.15中使用EKS，当我创建一个Storageclass、Persistent-Volume、Persistent-Volume-Claim和Deployment时，pod会失败，并显示以下错误：

Warning  FailedAttachVolume  71s (x2 over 3m11s)  attachdetach-controller              AttachVolume.Attach failed for volume "efs-pv" : attachment timeout for volume fs-<volume>
Warning  FailedMount         53s (x2 over 3m8s)   kubelet, ip-<ip-address>.ec2.internal  Unable to mount volumes for pod "influxdb-deployment-555f4c8b94-mldfs_default(2525d10b-e30b-4c4c-893e-10971e0c683e)": timeout expired waiting for volumes to attach or mount for pod "default"/"influxdb-deployment-555f4c8b94-mldfs". list of unmounted volumes=[persistent-storage]. list of unattached volumes=[persistent-storage]

然而，当我在没有构建Persistent-Volume的情况下尝试相同的方法时，它是成功的，并且创建了自己的似乎跳过了CSI。这就是我正在使用的：

deployment.yaml：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: influxdb-deployment
spec:
  selector:
    matchLabels:
      app: influxdb
  replicas: 1
  template:
    metadata:
      labels:
        app: influxdb
    spec:
      containers:
      - name: influxdb
        image: influxdb:1.7.10-alpine
        ports:
        - containerPort: 8086
        volumeMounts:
        - name: persistent-storage
          mountPath: /var/lib/influx
      volumes:
      - name: persistent-storage
        persistentVolumeClaim:
          claimName: efs-claim

storageclass.yaml：

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: efs-sc
provisioner: efs.csi.aws.com
reclaimPolicy: Retain

persistent-volume.yaml：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: efs-pv
spec:
  capacity:
    storage: 5Gi
  volumeMode: Filesystem
  accessModes:
    - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: efs-sc
  csi:
    driver: efs.csi.aws.com
    volumeHandle: fs-<volume-id>

persistent-volume-claim.yaml：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: efs-claim
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: efs-sc
  resources:
    requests:
      storage: 5Gi

知道发生了什么事吗？

Answer 1

这是aws EKS文档中未阐明的内容，但当您第一次使用storageclass作为设置时，这是一个必须做的事情。

EKS没有要设置的默认存储类

我以前没有在EFS上工作过，但是用gp2 (EBS)成功地设置了下面的yaml文件。

请在此处粘贴以供参考

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: gp2
  annotations:
    storageclass.kubernetes.io/is-default-class: "true"
provisioner: kubernetes.io/aws-ebs
parameters:
  type: gp2
  fsType: ext4
