Question

尝试在 AWS kops k8s群集上设置 Vora 2 。 pod vsystem-vrep 无法启动。在节点上的日志文件中，我看到：

sudo cat vsystem-vrep_30.log
{"log":"2018-03-27 12:54:04.164349|+0000|INFO |Starting Kernel NFS Server||vrep|1|Start|server.go(41)\u001e\n","stream":"stderr","time":"2018-03-27T12:54:04.164897827Z"}

我该如何解决这个问题？

在使用kops在AWS中安装Vora 2.1时，您需要首先设置vsystem所需的RWX存储类（默认AWS存储类是只读的）。在安装期间，您需要使用参数--vsystem-storage-class指向该存储类。此外，需要设置参数--vsystem-load-nfs-modules。我怀疑发生了错误，因为最后一个参数丢失了。

示例，如何调用install.sh：

./ install.sh --accept-license --deployment-type = cloud --namespace = xxx --docker-注册表= 123456789.dkr.ecr.us-west-1.amazonaws.com --vora-admin-username = xxx --vora-admin-password = xxx --cert-domain = my.host.domain.com --interactive-security-configuration = no - vsystem-storage-class = aws-efs --vsystem-load-nfs-modules

RWX存储类可以是例如按以下方式创建

在与kops集群相同的区域中创建EFS文件系统 - 请参阅https://us-west-2.console.aws.amazon.com/efs/home?region=us-west-2#/filesystems
- 创建文件系统
- 选择kops群集的VPC
- 添加kops master和worker安全组以挂载目标
- 可选择为其命名（例如，与您的kops群集相同，以了解它的用途）
- 使用剩余
- 创建后，请记下DNS名称（类似于fs-1234e567.efs.us-west-2.amazonaws.com）。
为Vora创建持久性卷和存储类

E.g。使用类似于下面的yaml文件，并指向新创建的EFS文件系统。

$ cat create_pv.yaml
apiVersion: v1
kind: PersistentVolume
metadata:
  name: vsystem-pv
spec:
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteMany
      persistentVolumeReclaimPolicy: Retain
      storageClassName: aws-efs
      nfs:
        path: /
        server: fs-1234e567.efs.us-west-2.amazonaws.com

$ cat create_sc.yaml
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: aws-efs
provisioner: xyz.com/aws-efs

kubectl create -f create_pv.yaml
kubectl create -f create_sc.yaml

-- check if newly created pv and sc exist
kubectl get pv
kubectl get storageclasses
