EKS吊舱中有多个卷架

Question

我正在运行AWS EKS，并希望其中一个容器将多个安装共享到同一容器。

我创建了1个EFS，2个PV和2个PVC

kind: Pod
metadata:
  name: app1
spec:
  containers:
  - name: app1
    image: busybox
    command: ["/bin/sh"]
    args: ["-c", "while true; do echo $(date -u) >> /data/out1.txt; sleep 5; done"]
    volumeMounts:
    - name: data
      mountPath: /data
    - name: docket
      mountPath: /docket
  volumes:
  - name: data
    persistentVolumeClaim:
      claimName: efs-data-claim

  - name: docket
    persistentVolumeClaim:
      claimName: efs-docket-claim

这些是我的PV / PVC

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

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

apiVersion: v1
kind: PersistentVolume
metadata:
  name: efs-docket-pv
spec:
  capacity:
    storage: 5Gi
  volumeMode: Filesystem
  accessModes:
    - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: efs-sc
  csi:
    driver: efs.csi.aws.com
    volumeHandle: fs-XXXXX
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: efs-docket-claim
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: efs-sc
  resources:
    requests:
      storage: 5Gi

..当我部署Pod时，总是出现以下错误

但是，如果我在两个安装座上都只使用1个PVC，它就可以正常工作。任何人都可以让我知道发生了什么。

Answer 1

PhysicalVolume和EFS存储之间存在一对一的映射。 如果您将两个不同的EFS与volumeHandle：fs-XXXXX和volumeHandle：fs-YYYYY一起使用，则它将起作用。
