Most CSI plugins will require bidirectional mount propagation, which can only be enabled for privileged pods.

#Insanelyi repo 2019 how to#

How to use a CSI volume?Īssuming a CSI storage plugin is already deployed on a Kubernetes cluster, users can use CSI volumes through the familiar Kubernetes storage API objects: PersistentVolumeClaims, PersistentVolumes, and StorageClasses.

#Insanelyi repo 2019 driver#

Kubernetes users interested in how to deploy or manage an existing CSI driver on Kubernetes should look at the documentation provided by the author of the CSI driver.

#Insanelyi repo 2019 registration#

The Kubelet device plugin registration mechanism, which is the means by which kubelet discovers new CSI drivers, has been promoted to GA in Kubernetes v1.13.

The Kubernetes CSIPersistentVolumeSource volume type has been promoted to GA.The Kubernetes VolumeAttachment object (introduced in v1.9 in the storage v1alpha1 group, and added to the v1beta1 group in v1.10) has been added to the storage v1 group in v1.13.

#Insanelyi repo 2019 drivers#

There were breaking changes between the CSI spec v0.1 and v0.2, so very old drivers implementing CSI 0.1 must be updated to be at least 0.2 compatible before use with Kubernetes v1.10.0+.

There were no breaking changes between CSI spec v0.2 and v0.3, so v0.2 drivers should also work with Kubernetes v1.10.0+.

Please note that with the release of the CSI 1.0 API, support for CSI drivers using 0.3 and older releases of the CSI API is deprecated, and is planned to be removed in Kubernetes v1.15.

There were breaking changes between CSI spec v0.3.0 and v1.0.0, but Kubernetes v1.13 supports both versions so either version will work with Kubernetes v1.13.

Kubernetes is now compatible with CSI spec v1.0 and v0.3 (instead of CSI spec v0.2).

With the promotion to GA, the Kubernetes implementation of CSI introduces the following changes: This gives Kubernetes users more options for storage and makes the system more secure and reliable. Using CSI, third-party storage providers can write and deploy plugins exposing new storage systems in Kubernetes without ever having to touch the core Kubernetes code. With the adoption of the Container Storage Interface, the Kubernetes volume layer becomes truly extensible. In addition, third-party storage code caused reliability and security issues in core Kubernetes binaries and the code was often difficult (and in some cases impossible) for Kubernetes maintainers to test and maintain.ĬSI was developed as a standard for exposing arbitrary block and file storage storage systems to containerized workloads on Container Orchestration Systems (COs) like Kubernetes. Why CSI?Īlthough prior to CSI Kubernetes provided a powerful volume plugin system, it was challenging to add support for new volume plugins to Kubernetes: volume plugins were “in-tree” meaning their code was 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) were forced to align with the Kubernetes release process. GA features are protected by the Kubernetes deprecation policy. The GA milestone indicates that Kubernetes users may depend on the feature and its API without fear of backwards incompatible changes in future causing regressions. Support for CSI was introduced as alpha in Kubernetes v1.9 release, and promoted to beta in the Kubernetes v1.10 release. The Kubernetes implementation of the Container Storage Interface (CSI) has been promoted to GA in the Kubernetes v1.13 release. Author: Saad Ali, Senior Software Engineer, Google
