1.概念
2. helm安装storageclass
2.1 环境准备
NFS服务器已搭建
ip：10.252.97.213
使用存储目录：/data/nfs/storagehelm已安装
2.2 安装storageclass
[root@DoM01 ~]# git clone https://github.com/helm/charts.git
[root@DoM01 ~]# cd charts/
[root@DoM01 ~]# helm install stable/nfs-client-provisioner --set nfs.server=10.252.97.213 --set nfs.path=/data/nfs/storage
[root@DoM01 ~]# git clone https://github.com/helm/charts.git
[root@DoM01 ~]# cd charts/stable/nfs-client-provisioner
[root@DoM01 ~]# helm install storageclass --set nfs.server=10.252.97.213 --set nfs.path=/data/nfs/storage -n storageclass ./
- 查看结果
[root@DoM01 ~]# kubectl get storageclasses.storage.k8s.io
NAME PROVISIONER AGE
nfs-client cluster.local/storageclass-nfs-client-provisioner 1d
2.3 测试
- 创建
test_pvc.yaml文件
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: test-claim1
spec:
accessModes:
- ReadWriteMany
resources:
requests:
storage: 1Mi
storageClassName: nfs-client
- 创建测试pvc
# kubectl create -f test_pvc.yaml
- 查看结果
[root@DoM01 storageclass]# kubectl get pvc
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
test-claim1 Bound pvc-0d1ee112-bf86-45cc-afe0-c03c014edb43 1Mi RWX nfs-client 1d
2.4 设置默认storageclass
- 设置默认值
# kubectl patch storageclass nfs-client -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
- 查看
[root@DoM01 ~]# kubectl get storageclasses.storage.k8s.io
NAME PROVISIONER AGE
nfs-client (default) cluster.local/storageclass-nfs-client-provisioner 1d
- 删除默认值
# kubectl patch storageclass nfs-client -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}'
3. 手动安装storageclass
说明：nfs服务器准备同上
3.1 Provisioner（供应者）
创建
nfs-client.yaml文件如下：
kind: Deployment
apiVersion: extensions/v1beta1
metadata:
name: nfs-client-provisioner
spec:
replicas: 1
strategy:
type: Recreate
template:
metadata:
labels:
app: nfs-client-provisioner
spec:
serviceAccountName: nfs-client-provisioner
containers:
- name: nfs-client-provisioner
image: quay.io/external_storage/nfs-client-provisioner:latest
volumeMounts:
- name: nfs-client-root
mountPath: /persistentvolumes
env:
- name: PROVISIONER_NAME
value: fuseim.pri/ifs
- name: NFS_SERVER
value: 10.252.97.208
- name: NFS_PATH
value: /data/nfs/storage
volumes:
- name: nfs-client-root
nfs:
server: 10.252.97.208
path: /data/nfs/storage
- 权限
创建
nfs-client-sa.yaml文件：
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: test-claim1
spec:
accessModes:
- ReadWriteMany
resources:
requests:
storagapiVersion: v1
kind: ServiceAccount
metadata:
name: nfs-client-provisioner
---
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: ["create", "delete", "get", "list", "watch", "patch", "update"]
---
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
3.3 创建storageclass
创建
storageclass.yaml文件:
# cat storageclass.yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: df-storage
provisioner: fuseim.pri/ifs #对应供应者中变量 PROVISIONER_NAME 的值
3.4 测试和设置默认值
同 "2. helm安装storageclass"
4. 创建多个storageclass
如果供应者不变，直接创建storageclass即可
- 创建
storageclass02.yaml文件：
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: hello-world
provisioner: fuseim.pri/ifs
- 启动
# kubectl create -f storageclass02.yaml
5. 更改nfs存储
- 方法一
更改storageclass.yaml文件后，用 apply命令修改即可 - 方法二
edit直接修改供应者的deployment
