Question

我正在将EKS与Kubernetes 1.15版配合使用，当我创建存储类，持久卷，持久卷声明和部署时，pod失败，并显示以下消息：

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]

但是，当我尝试不构建持久卷而进行相同操作时，它会成功，并创建自己的文件，从而似乎跳过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

有什么想法吗？

Answer 1

这在aws EKS文档中没有明确说明，但是当您打算将storageclass用作首次设置时必须做。

EKS没有要设置的默认存储类别

我以前没有在EKS上使用EFS进行工作，但是确实使用gap2（EBS）设置了以下yaml文件。

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

在Pod出现之前，挂载EKS EFS CSI超时
