tools: Add a CSI Driver for SPDK Direct Volume

[Apokleos]

This is opened for GLCC.

Introduction

This project aims to develop a CSI (Container Storage Interface) Driver for Kata based on Direct Volume SPDK Volume, to enable users to use SPDK Volume in a Kubernetes environment just like any other storage volume. Kata container virtualization technology provides a lightweight container runtime environment for cloud-native applications, while the SPDK storage acceleration suite offers efficient I/O performance. By combining these two technologies, a more efficient storage solution can be provided for cloud-native applications. The project will implement a CSI-compliant driver, allowing users to interact with SPDK Volume through the CSI interface in Kubernetes, enabling dynamic management and usage of storage resources.

Target

We hope to achieve the following goals:

• Develop a CSI Driver: Implement a CSI-compliant driver that supports the CSI interface of Kubernetes and can interact with SPDK Volume.
• Enhance functionality: Support basic operations such as creation, deletion, mounting, and unmounting, as well as advanced features like snapshots and cloning.
• Perform integration testing: Ensure that the CSI Driver and the SPDK Volume based on Direct Volume in Kata can work properly in a Kubernetes environment, and verify their stability and reliability through test cases.
• Provide documentation and examples: Write clear documentation and example code to introduce users to how to configure and use the CSI Driver, as well as how to interact with SPDK Volume.
