FlexVolume (Discarded)

Introduction

CCE Container Storage (FlexVolume), also called storage-driver, functions as a standard Kubernetes FlexVolume plugin to allow containers to use EVS, SFS, OBS, and SFS Turbo storage resources. By installing and upgrading storage-driver, you can quickly install and update cloud storage capabilities.

FlexVolume is a system resource add-on. It is installed by default when a cluster of Kubernetes v1.13 or earlier is created.

Notes and Constraints

  • For clusters created in CCE, Kubernetes v1.15.11 is a transitional version in which the FlexVolume add-on is compatible with the CSI add-on (Everest). Clusters of v1.17 and later versions do not support FlexVolume anymore. Use the Everest add-on.
  • The FlexVolume add-on will be maintained by Kubernetes developers, but new functionality will only be added to Everest. Do not create CCE storage that uses the FlexVolume add-on (storage-driver) anymore. Otherwise, storage may malfunction.
  • This add-on can be installed only in clusters of v1.13 or earlier. By default, the Everest add-on is installed when clusters of v1.15 or later are created.

    In a cluster of v1.13 or earlier, when an upgrade or bug fix is available for storage functionalities, you only need to install or upgrade the storage-driver add-on. Upgrading the cluster or creating a cluster is not required.

Installing the Add-on

This add-on has been installed by default. If it is uninstalled due to some reasons, you can reinstall it by performing the following steps:

If storage-driver is not installed in a cluster, perform the following steps to install it:

  1. Log in to the CCE console and click the cluster name to access the cluster console. Choose Add-ons in the navigation pane, locate CCE Container Storage (FlexVolume) on the right, and click Install.
  2. Click Install to install the add-on. Note that the storage-driver has no configurable parameters and can be directly installed.
