Also, CSI enables the use of modern\nstorage features, such as and resizing and snapshots.\nBy default, GKE on Azure provisions [Azure Disk](https://docs.microsoft.com/en-us/azure/virtual-machines/managed-disks-overview) volumes with the [`azuredisk-csi-driver`](https://github.com/kubernetes-sigs/azuredisk-csi-driver). You can also provision [Azure File](/kubernetes-engine/multi-cloud/docs/azure/how-to/use-azure-file) shares with the [`azurefile-csi-driver`](https://github.com/kubernetes-sigs/azurefile-csi-driver). If you want to use another type of storage volume, you can install a CSI driver.\n\n\u003cbr /\u003e\n\nAfter installing a CSI driver, you need to create a Kubernetes\n[StorageClass](https://kubernetes.io/docs/concepts/storage/storage-classes/).\nYou set the CSI driver as the provisioner for the StorageClass. Then, you can\n[set the StorageClass as default](/kubernetes-engine/multi-cloud/docs/azure/how-to/storage-class#set_default),\nor configure your workloads to use the StorageClass.\n\nBefore you begin\n----------------\n\n[Connect to your cluster](/kubernetes-engine/multi-cloud/docs/azure/how-to/connect-and-authenticate-to-your-cluster)\n\nInstall a vendor's CSI driver\n-----------------------------\n\nStorage vendors are responsible for providing installation instructions for\ntheir CSI drivers. See the list of\n[CSI drivers](https://kubernetes-csi.github.io/docs/drivers.html)\nin the CSI documentation.\n\nFollow the installation instructions for your CSI driver, and then continue with\nthe next steps on this page.\n\nGoogle does not provide support or instructions for third-party drivers.\nContact your storage vendor for support.\n\nVerify your driver installation\n-------------------------------\n\nAfter you install a CSI driver, you can verify the installation by running\nthe following commands. \n\n kubectl get csinodes \\\n -o jsonpath='{range .items[*]} {.metadata.name}{\": \"} {range .spec.drivers[*]} {.name}{\"\\n\"} {end}{end}'\n\nUse a CSI driver\n----------------\n\nTo use a CSI driver, do the following:\n\n1. Create a custom [StorageClass](/kubernetes-engine/multi-cloud/docs/azure/how-to/storage-class#custom)\n which references the driver in its `provisioner` field.\n\n2. To provision storage, you can either:\n\n - Reference the StorageClass in a [StatefulSet](https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/)'s `volumeClaimTemplates` specification.\n - [Set it as the cluster's default StorageClass](/kubernetes-engine/multi-cloud/docs/azure/how-to/storage-class#set_default).\n\nConsiderations for StorageClass backed by a CSI driver\n------------------------------------------------------\n\nWhen you create a StorageClass, consider the following:\n\n- Check your CSI driver documentation for\n [driver-specific parameters](https://kubernetes.io/docs/concepts/storage/storage-classes/#the-storageclass-resource)\n that you provide to your StorageClass, including the provisioner name.\n\n- You should name the StorageClass after its properties (such as `fast` or\n `highly-replicated`), rather than after the name of the specific driver or\n appliance behind it. When you name a StorageClass after its properties, you can\n create StorageClasses with the same name in different clusters and\n environments. Then, configure your workloads to use the same StorageClass.\n\nWhat's next?\n------------\n\n- Create a [StorageClass](/kubernetes-engine/multi-cloud/docs/azure/how-to/storage-class#custom) which references the CSI driver."]]
