使用Helm安装nfs-provisioner

废弃理由：Kubernetes升级到1.20后不再支持selflink（其实这个我也不是很懂），导致创建pvc时会报如下错误：


I0117 03:07:49.409564       1 controller.go:987] provision "default/test-claim" class "nfs-client": started
E0117 03:07:49.484879       1 controller.go:1004] provision "default/test-claim" class "nfs-client": unexpected error getting claim reference: selfLink was empty, can't make reference
I0117 03:20:19.438488       1 controller.go:987] provision "default/test-claim" class "nfs-client": started
E0117 03:20:19.441774       1 controller.go:1004] provision "default/test-claim" class "nfs-client": unexpected error getting claim reference: selfLink was empty, can't make reference

相关讨论资料如下：

指令如下：

# 添加存储库
helm repo add azure http://mirror.azure.cn/kubernetes/charts/

# 搜索nfs-client-provisioner
helm search repo nfs-client-provisioner

# 拿到其values.yaml文件
helm inspect values azure/nfs-client-provisioner > values.yaml

修改vaues.yaml文件，暂时只修改如下内容：

nfs:
  server: 192.168.23.60
  path: /root/NFSDirectory

安装nfs-client

helm install nfs-client azure/nfs-client-provisioner \
    --values values.yaml \
    --namespace nfs-client \
    --create-namespace

我目前使用的是别人的Chart，未来我可能会开发自己的Chart。
