如果项目需要使用文件系统，需要宿主主机的一个目录映射到容器，可以考虑使用PVC。
-
PV（PersistentVolume）
- 创建PV的定义文件
apiVersion: v1 kind: PersistentVolume metadata:name: pvc-b5f39ddf-b86a-4a65-9fc3-b9f59d65920eannotations:pv.kubernetes.io/provisioned-by: nfs.csi.k8s.iovolume.kubernetes.io/provisioner-deletion-secret-name: ''volume.kubernetes.io/provisioner-deletion-secret-namespace: ''finalizers:- external-provisioner.volume.kubernetes.io/finalizer- kubernetes.io/pv-protection spec:capacity:storage: 10Gicsi:driver: nfs.csi.k8s.iovolumeHandle: 192.168.10.100volumeAttributes:csi.storage.k8s.io/pv/name: pvc-b5f39ddf-b86a-4a65-9fc3-b9f59d65920eserver: 192.168.10.100share: /data/nfs/scstorage.kubernetes.io/csiProvisionerIdentity: 1740995712643-6298-nfs.csi.k8s.iosubdir: pvc-b5f39ddf-b86a-4a65-9fc3-b9f59d65920eaccessModes:- ReadWriteManypersistentVolumeReclaimPolicy: DeletestorageClassName: nfs-csimountOptions:- nfsvers=4.1volumeMode: Filesystem- 执行创建：kubectl apply -f pv.yaml
- 查看PV：kubectl get pv
-
PVC（PersistentVolumeClaim）
- 创建PVC的定义文件
apiVersion: v1 kind: PersistentVolumeClaim metadata:name: s1-pvcnamespace: sample1annotations:kubesphere.io/creator: adminpv.kubernetes.io/bind-completed: 'yes'pv.kubernetes.io/bound-by-controller: 'yes'volume.beta.kubernetes.io/storage-provisioner: nfs.csi.k8s.iovolume.kubernetes.io/storage-provisioner: nfs.csi.k8s.iofinalizers:- kubernetes.io/pvc-protection spec:accessModes:- ReadWriteManyresources:requests:storage: 10GivolumeName: pvc-b5f39ddf-b86a-4a65-9fc3-b9f59d65920estorageClassName: nfs-csivolumeMode: Filesystem- 执行创建：kubectl apply -f pvc.yaml
- 查看PVC：kubectl get pvc -n sample1
-
在Pod中挂载 PVC
- 修改Pod的定义文件
