Kubernetes:使用NFS的动态持久卷配置 [英] Kubernetes : Dynamic Persistent Volume provisioning using NFS

问题描述

我有多节点kubernetes设置.我正在尝试使用带有NFS卷插件的存储类来动态分配持久卷. 我找到了glusterfs，aws-ebs等的存储类示例，但是没有找到NFS的任何示例. 如果仅创建PV和PVC，则NFS可以很好地工作(没有存储类). 我试图通过引用其他插件为NFS编写存储类文件.请在下面参考，

I have multi node kubernetes setup. I am trying to allocate a Persistent volume dynamically using storage classes with NFS volume plugin. I found storage classes examples for glusterfs, aws-ebs, etc.but, I didn't find any example for NFS. If I create PV and PVC only then NFS works very well(Without storage class). I tried to write storage class file for NFS, by referring other plugins. please refer it below,

nfs-storage-class.yaml

nfs-storage-class.yaml

kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
  namespace: kube-system
  name: my-storage
  annotations:
    storageclass.beta.kubernetes.io/is-default-class: "true"
  labels:
    kubernetes.io/cluster-service: "true"

provisioner: kubernetes.io/nfs
parameters:
  path: /nfsfileshare
  server: <nfs-server-ip> 

nfs-pv-claim.yaml

nfs-pv-claim.yaml

apiVersion: v1
metadata:
  name: demo-claim
  annotations:
    volume.beta.kubernetes.io/storage-class: my-storage
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 3Gi

它没有用.所以，我的问题是，我们可以为NFS编写存储类吗?它支持动态提供吗?

It didn't worked. So, my question is, Can we write a storage class for NFS? Does it support dynamic provisioing?

推荐答案

使用NFS进行动态存储配置不起作用，最好使用glusterfs.有一个很好的教程，解决了设置过程中的常见问题. http://blog.lwolf.org/post /how-i-deployed-glusterfs-cluster-to-kubernetes/

Dynamic storage provisioning using NFS doesn't work, better use glusterfs. There's a good tutorial with fixed to common problems while setting up. http://blog.lwolf.org/post/how-i-deployed-glusterfs-cluster-to-kubernetes/
