Kubernetes集群中NFS类型的存储没有内置 Provisioner。但是您可以在集群中为NFS配置外部Provisioner。 Nfs-client-provisioner是一个开源的NFS 外部Provisioner,利用NFS Server为Kubernetes集群提供持久化存储,并且支持动态创建PV。 There are also cases when 3rd party storage vendors … In this post, I will guide you to setup storage class based on NFS using a program named "nfs-client-provisioner". We can now view the PVC and PV that was allocated. They’re similar to a voucher that your deployment can redeem for storage access. Let’s create a pod to use our PVC. The following documentation is intended to explain the procedure for deploying Dynamic NFS Provisioning in Kubernetes. provisioner: example.com/nfs To delete the PV and PVC use “kubectl delete”. (class.yaml default-sc.yaml deployment.yaml rbac.yaml) We will use the rbac.yaml file to create the service account for nfs and cluster role and bindings. NetApp Trident is a storage provisioner for Kubernetes that allows users to take advantage of NetApp storage services, both on-premises and in the cloud. Note that the volume must have a supported file system on it: any local filesystem on Linux is supported & NFS is not supported. The PV was created automatically by the nfs-provisoner. ²ç»å®‰è£…好的NFS服务器,并且NFS服务器与Kubernetes的Slave节点都能网络连通。 Dynamic volume provisioning allows storage volumes to be created on-demand. The goal of this post is to understand how NFS provisioning work in Kubernetes. be a PVC. The dynamic nfs provisioning feature eliminates the need for cluster administrators to pre-provision storage. But first we’ll need to edit the deployment.yaml file. You also have the provision to combine it with Cloud Volumes ONTAP which … nfs-client from kubernetes-incubator project is an automatic provisioner that use your existing and already configured NFS server to support dynamic provisioning of Kubernetes… All Rights Reserved. However, one of the simplest and easiest ways is to set up the NFS server in a Linux machine and provide the back-end storage to the NFS client provisioner within the Kubernetes cluster.

Kubernetes : Dynamic Volume Provisioning (NFS) 2020/08/24 : To use Dynamic Volume Provisioning feature when using Persistent Storage, it's possible to create PV (Persistent Volume) dynamically without creating PV manually by Cluster Administrator when created PVC (Persistent Volume Claim) by users. For information on running multiple instances of nfs-provisioner see Running Multiple Provisioners. This exanple is for centos 7. Edward Cooke. Dynamic NFS Provisioning:  is allows storage volumes to be created on-demand. The incubator team for the project is: Participation in the Kubernetes community is governed by the Kubernetes Code of Conduct. ; 启动nfs-provisioner $ kubectl create -f deploy.yml -f rbac.yml -f class.yml Go here for a demo of how to run nfs-provisioner. The version you are currently viewing is a static snapshot. Deleting the pod will delete the pod but not the PV and PVC. Next let’s run the “class.yaml” to set up the storageclass. nfs-provisioner is an out-of-tree dynamic provisioner for Kubernetes 1.4. be a PVC. 下面是example-nfs的StorageClass配置文件,此配置文件定义了一个名称为nfs-storageclass的存储类,此存储类的提供者为nfs-provisioner。 apiVersion: storage.k8s.io/v1 kind: StorageClass metadata: name: nfs-storageclass provisioner: nfs-provisioner. Work fast with our official CLI. role.rbac.authorization.k8s.io/leader-locking-nfs-client-provisioner 20m 通过kubectl create -f命令使用上面的配置文件创建: Log onto one of the worker nodes and mount the nfs filesystem and. Choose some volume for your nfs-provisioner instance to store its state & data in and mount the volume at /export in deploy/kube-config/deployment.yaml. We’ll first create “/srv/nfs/kubedata“. One of the ways Kubernetes allows applications to access storage is the standard Network File Service (NFS) protocol. A PersistentVolume is provisioned for the PersistentVolumeClaim. For more information on how dynamic provisioning works, see the docs or this blog post. I starting writing software in 1989 on a TI-99/4a. The NFS-client provisioner. Step 2. Learn more.
