The Kubernetes implementation of the Container Storage Interface (CSI) is now beta in Kubernetes v1.10. CSI was introduced as alpha in Kubernetes v1.9.
Kubernetes features are generally introduced as alpha and moved to beta (and eventually to stable/GA) over subsequent Kubernetes releases. This process allows Kubernetes developers to get feedback, discover and fix issues, iterate on the designs, and deliver high quality, production grade features.
Why introduce Container Storage Interface in Kubernetes?
Although Kubernetes already provides a powerful volume plugin system that makes it easy to consume different types of block and file storage, adding support for new volume plugins has been challenging. Because volume plugins are currently “in-tree”—volume plugins are part of the core Kubernetes code and shipped with the core Kubernetes binaries—vendors wanting to add support for their storage system to Kubernetes (or even fix a bug in an existing volume plugin) must align themselves with the Kubernetes release process.
With the adoption of the Container Storage Interface, the Kubernetes volume layer becomes truly extensible. Third party storage developers can now write and deploy volume plugins exposing new storage systems in Kubernetes without ever having to touch the core Kubernetes code. This will result in even more options for the storage that backs Kubernetes users’ stateful containerized workloads.
What’s new in Beta?
With the promotion to beta CSI is now enabled by default on standard Kubernetes deployments instead of being opt-in.
The move of the Kubernetes implementation of CSI to beta also means:
* Kubernetes is compatible with v0.2 of the CSI spec (instead of v0.1)
* There were breaking changes between the CSI spec v0.1 and v0.2, so existing CSI drivers must be updated to be 0.2 compatible before use with Kubernetes 1.10.0+.
* Mount propagation, a feature that allows bidirectional mounts between containers and host (a requirement for containerized CSI drivers), has also moved to beta.
* The Kubernetes
VolumeAttachment object, introduced in v1.9 in the storage v1alpha1 group, has been added to the storage v1beta1 group.
* The Kubernetes
CSIPersistentVolumeSource object has been promoted to beta.
VolumeAttributes field was added to Kubernetes
CSIPersistentVolumeSource object (in alpha this was passed around via annotations).
* Node authorizer has been updated to limit access to
VolumeAttachment objects from kubelet.
* The Kubernetes
CSIPersistentVolumeSource object and the CSI external-provisioner have been modified to allow passing of secrets to the CSI volume plugin.
* The Kubernetes
CSIPersistentVolumeSource has been modified to allow passing in filesystem type (previously always assumed to be
* A new optional call,
NodeStageVolume, has been added to the CSI spec, and the Kubernetes CSI volume plugin has been modified to call
MountDevice (in alpha this step was a no-op).
How do I deploy a CSI driver on a Kubernetes Cluster?
CSI plugin authors must provide their own instructions for deploying their plugin on Kubernetes.
The Kubernetes-CSI implementation team created a sample hostpath CSI driver. The sample provides a rough idea of what the deployment process for a CSI driver looks like. Production drivers, however, would deploy node components via a DaemonSet and controller components via a StatefulSet rather than a single pod (for example, see the deployment files for the GCE PD driver).
How do I use a CSI Volume in my Kubernetes pod?
Assuming a CSI storage plugin is already deployed on your cluster, you can use it through the familiar Kubernetes storage primitives:
CSI is a beta feature in Kubernetes v1.10. Although it is enabled by default, it may require the following flag:
* API server binary and kubelet binaries:
* Most CSI plugins will require bidirectional mount propagation, which can only be enabled for privileged pods. Privileged pods are only permitted on clusters where this flag has been set to true (this is the default in some environments like GCE, GKE, and kubeadm).
You can enable automatic creation/deletion of volumes for CSI Storage plugins that support dynamic provisioning by creating a
StorageClass pointing to the CSI plugin.
StorageClass, for example, enables dynamic creation of “
fast-storage” volumes by a CSI volume plugin called “
kind: StorageClass apiVersion: storage.k8s.io/v1 metadata: name: fast-storage provisioner: com.example.csi-driver parameters: type: pd-ssd csiProvisionerSecretName: mysecret csiProvisionerSecretNamespace: mynamespace
New for beta, the default CSI external-provisioner reserves the parameter keys
csiProvisionerSecretNamespace. If specified, it fetches the secret and passes it to the CSI driver during provisioning.
Dynamic provisioning is triggered by the creation of a
PersistentVolumeClaim object. The following
PersistentVolumeClaim, for example, triggers dynamic provisioning using the
apiVersion: v1 kind: PersistentVolumeClaim metadata: name: my-request-for-storage spec: accessModes: - ReadWriteOnce resources: requests: storage: 5Gi storageClassName: fast-storage
When volume provisioning is invoked, the parameter type:
pd-ssd and the secret any referenced secret(s) are passed to the CSI plugin
com.example.csi-driver via a
CreateVolume call. In response, the external volume plugin provisions a new volume and then automatically create a
PersistentVolume object to represent the new volume. Kubernetes then binds the new
PersistentVolume object to the
PersistentVolumeClaim, making it ready to use.
If the fast-storage StorageClass is marked as “default”, there is no need to include the storageClassName in the PersistentVolumeClaim, it will be used by default.
You can always expose a pre-existing volume in Kubernetes by manually creating a
PersistentVolume object to represent the existing volume. The following
PersistentVolume, for example, exposes a volume with the name “
existingVolumeName” belonging to a CSI storage plugin called “
apiVersion: v1 kind: PersistentVolume metadata: name: my-manually-created-pv spec: capacity: storage: 5Gi accessModes: - ReadWriteOnce persistentVolumeReclaimPolicy: Retain csi: driver: com.example.csi-driver volumeHandle: existingVolumeName readOnly: false fsType: ext4 volumeAttributes: foo: bar controllerPublishSecretRef: name: mysecret1 namespace: mynamespace nodeStageSecretRef: name: mysecret2 namespace: mynamespace nodePublishSecretRef name: mysecret3 namespace: mynamespace
Attaching and Mounting
You can reference a
PersistentVolumeClaim that is bound to a CSI volume in any pod or pod template.
kind: Pod apiVersion: v1 metadata: name: my-pod spec: containers: - name: my-frontend image: nginx volumeMounts: - mountPath: "/var/www/html" name: my-csi-volume volumes: - name: my-csi-volume persistentVolumeClaim: claimName: my-request-for-storage
When the pod referencing a CSI volume is scheduled, Kubernetes will trigger the appropriate operations against the external CSI plugin (
NodePublishVolume, etc.) to ensure the specified volume is attached, mounted, and ready to use by the containers in the pod.
How do I write a CSI driver?
CSI Volume Driver deployments on Kubernetes must meet some minimum requirements.
The minimum requirements document also outlines the suggested mechanism for deploying an arbitrary containerized CSI driver on Kubernetes. This mechanism can be used by a Storage Provider to simplify deployment of containerized CSI compatible volume drivers on Kubernetes.
As part of the suggested deployment process, the Kubernetes team provides the following sidecar (helper) containers:
* watches Kubernetes
VolumeAttachment objects and triggers
ControllerUnpublish operations against a CSI endpoint
* watches Kubernetes
PersistentVolumeClaim objects and triggers
DeleteVolume operations against a CSI endpoint
* registers the CSI driver with kubelet (in the future) and adds the drivers custom
NodeId (retrieved via
GetNodeID call against the CSI endpoint) to an annotation on the Kubernetes Node API Object
* can be included in a CSI plugin pod to enable the Kubernetes Liveness Probe mechanism
Storage vendors can build Kubernetes deployments for their plugins using these components, while leaving their CSI driver completely unaware of Kubernetes.
Where can I find CSI drivers?
CSI drivers are developed and maintained by third parties. You can find a non-definitive list of some sample and production CSI drivers.
What about FlexVolumes?
As mentioned in the alpha release blog post, FlexVolume plugin was an earlier attempt to make the Kubernetes volume plugin system extensible. Although it enables third party storage vendors to write drivers “out-of-tree”, because it is an exec based API, FlexVolumes requires files for third party driver binaries (or scripts) to be copied to a special plugin directory on the root filesystem of every node (and, in some cases, master) machine. This requires a cluster admin to have write access to the host filesystem for each node and some external mechanism to ensure that the driver file is recreated if deleted, just to deploy a volume plugin.
In addition to being difficult to deploy, Flex did not address the pain of plugin dependencies: Volume plugins tend to have many external requirements (on mount and filesystem tools, for example). These dependencies are assumed to be available on the underlying host OS, which is often not the case.
CSI addresses these issues by not only enabling storage plugins to be developed out-of-tree, but also containerized and deployed via standard Kubernetes primitives.
If you still have questions about in-tree volumes vs CSI vs Flex, please see the Volume Plugin FAQ.
What will happen to the in-tree volume plugins?
Once CSI reaches stability, we plan to migrate most of the in-tree volume plugins to CSI. Stay tuned for more details as the Kubernetes CSI implementation approaches stable.
What are the limitations of beta?
The beta implementation of CSI has the following limitations:
* Block volumes are not supported; only file.
* CSI drivers must be deployed with the provided external-attacher sidecar plugin, even if they don’t implement
* Topology awareness is not supported for CSI volumes, including the ability to share information about where a volume is provisioned (zone, regions, etc.) with the Kubernetes scheduler to allow it to make smarter scheduling decisions, and the ability for the Kubernetes scheduler or a cluster administrator or an application developer to specify where a volume should be provisioned.
driver-registrar requires permissions to modify all Kubernetes node API objects which could result in a compromised node gaining the ability to do the same.
Depending on feedback and adoption, the Kubernetes team plans to push the CSI implementation to GA in 1.12.
The team would like to encourage storage vendors to start developing CSI drivers, deploying them on Kubernetes, and sharing feedback with the team via the Kubernetes Slack channel wg-csi, the Google group kubernetes-sig-storage-wg-csi, or any of the standard SIG storage communication channels.
