K8s使用NFS持久卷配置
nfs服务部署
参照网上文档操作,太简单,这里不提。
创建storageclass
kind: StorageClassmetadata:
name: slow
namespace: ns1
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: Immediate
创建持久卷
apiVersion: v1kind: PersistentVolume
metadata:
name: vulfiles
namespace: ns1
labels:
name: vulfiles
spec:
capacity:
storage: 5Gi
volumeMode: Filesystem
accessModes:
- ReadOnlyMany
persistentVolumeReclaimPolicy: Recycle
storageClassName: slow
mountOptions:
- hard
- nfsvers=4.1
nfs:
path: /opt/data
server: 192.168.199.150
申请使用持久卷部分空间
apiVersion: v1kind: PersistentVolumeClaim
metadata:
name: vulpvc
namespace: ns1
spec:
accessModes:
- ReadOnlyMany
volumeMode: Filesystem
resources:
requests:
storage: 5Gi
storageClassName: slow
selector:
matchLabels:
name: vulfiles
pvc 通过 matchLabels和pv中的label匹配,来关联要使用的存储空间。
容器中配置
volumes: - name: vuldata
persistentVolumeClaim:
claimName: vulpvc
containers:
- name: container-xxx
image: xxx/kkk
imagePullPolicy: Always
volumeMounts:
- mountPath: "/opt/data"
name: vuldata
