# Configure Storage Class Provider with NFS
|
||
|
|
|
||
|
|
1. Create storage class
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
apiVersion: storage.k8s.io/v1
|
||
|
|
kind: StorageClass
|
||
|
|
metadata:
|
||
|
|
name: nfs-k8s-data
|
||
|
|
annotations:
|
||
|
|
storageclass.kubernetes.io/is-default-class: "true"
|
||
|
|
provisioner: k8s/nfs
|
||
|
|
allowVolumeExpansion: true
|
||
|
|
```
|
||
|
|
|
||
|
|
2. Create service account and permission
|
||
|
|
|
||
|
|
- Create service account
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
apiVersion: v1
|
||
|
|
kind: ServiceAccount
|
||
|
|
metadata:
|
||
|
|
name: nfs-client-provisioner
|
||
|
|
```
|
||
|
|
|
||
|
|
- Define cluster role
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
kind: ClusterRole
|
||
|
|
apiVersion: rbac.authorization.k8s.io/v1
|
||
|
|
metadata:
|
||
|
|
name: nfs-client-provisioner-runner
|
||
|
|
rules:
|
||
|
|
- apiGroups: [""]
|
||
|
|
resources: ["persistentvolumes"]
|
||
|
|
verbs: ["get", "list", "watch", "create", "delete"]
|
||
|
|
- apiGroups: [""]
|
||
|
|
resources: ["persistentvolumeclaims"]
|
||
|
|
verbs: ["get", "list", "watch", "update"]
|
||
|
|
- apiGroups: ["storage.k8s.io"]
|
||
|
|
resources: ["storageclasses"]
|
||
|
|
verbs: ["get", "list", "watch"]
|
||
|
|
- apiGroups: [""]
|
||
|
|
resources: ["events"]
|
||
|
|
verbs: ["list", "watch", "create", "update", "patch"]
|
||
|
|
- apiGroups: [""]
|
||
|
|
resources: ["endpoints"]
|
||
|
|
verbs: ["get", "list", "watch", "create", "update", "patch"]
|
||
|
|
```
|
||
|
|
|
||
|
|
- Bind cluster to service account
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
kind: ClusterRoleBinding
|
||
|
|
apiVersion: rbac.authorization.k8s.io/v1
|
||
|
|
metadata:
|
||
|
|
name: run-nfs-client-provisioner
|
||
|
|
subjects:
|
||
|
|
- kind: ServiceAccount
|
||
|
|
name: nfs-client-provisioner
|
||
|
|
namespace: default
|
||
|
|
roleRef:
|
||
|
|
kind: ClusterRole
|
||
|
|
name: nfs-client-provisioner-runner
|
||
|
|
apiGroup: rbac.authorization.k8s.io
|
||
|
|
```
|
||
|
|
|
||
|
|
3. Deploy provisioner as pod
|
||
|
|
|
||

|
||
|
|
apiVersion: extensions/v1beta1

|
|
- name: nfs-client-root
|
||
|
|
mountPath: /persistentvolumes
|
||
|
|
env:

|
||
|
|
volumes:
