      Feature Overview
      Provide CSI drivers to replace all the intree cloud provider drivers we currently have. These drivers will probably be released as tech preview versions first before being promoted to GA.

      Goals

      • Framework for rapid creation of CSI drivers for our cloud providers
      • CSI driver for AWS EBS
      • CSI driver for AWS EFS
      • CSI driver for GCP
      • CSI driver for Azure
      • CSI driver for VMware vSphere
      • CSI Driver for Azure Stack
      • CSI Driver for Alicloud
      • CSI Driver for IBM Cloud

      Requirements

      Requirement Notes isMvp?
      Framework for CSI driver  TBD Yes
      Drivers should be available to install both in disconnected and connected mode   Yes
      Drivers should upgrade from release to release without any impact   Yes
      Drivers should be installable via CVO (when in-tree plugin exists)    

      Out of Scope

      This work will only cover the drivers themselves, it will not include

      • enhancements to the CSI API framework
      • the migration to said drivers from the the intree drivers
      • work for non-cloud provider storage drivers (FC-SAN, iSCSI) being converted to CSI drivers

      Background, and strategic fit
      In a future Kubernetes release (currently 1.21) intree cloud provider drivers will be deprecated and replaced with CSI equivalents, we need the drivers created so that we continue to support the ecosystems in an appropriate way.

      Assumptions

      • Storage SIG won't move out the changeover to a later Kubernetes release

      Customer Considerations
      Customers will need to be able to use the storage they want.

      Documentation Considerations

      • Target audience: cluster admins
      • Updated content: update storage docs to show how to use these drivers (also better expose the capabilities)
