Baidu Cloud CSI Plugin

English | 简体中文

Introduction

Baidu Cloud CSI plugins implement an interface between CSI enabled Container Orchestrator and Baidu Cloud Storage.

Features

CDS Driver

The following CSI gRPC calls are implemented:

• Controller Service: CreateVolume, DeleteVolume, ControllerPublishVolume, ControllerUnpublishVolume, ControllerGetCapabilities, ValidateVolumeCapabilities
• Node Service: NodeStageVolume, NodeUnstageVolume, NodePublishVolume, NodeUnpublishVolume, NodeGetCapabilities, NodeGetInfo
• Identity Service: GetPluginInfo, GetPluginCapabilities, Probe

Features:

• Static Provisioning - create persistence volume (PV) from the existing CDS volume and consume the PV from container using persistence volume claim (PVC).
• Dynamic Provisioning - uses persistence volume claim (PVC) to request the Kuberenetes to create the CDS volume on behalf of user and consumes the volume from inside container.
• Mount Option - mount options could be specified in persistence volume (PV) to define how the volume should be mounted.
• Block Volume - consumes the CDS volume as a raw block device for latency sensitive application. The corresponding CSI feature (CSIBlockVolume) is GA since Kubernetes 1.18.

BOS Driver

The following CSI gRPC calls are implemented:

• Node Service: NodePublishVolume, NodeUnpublishVolume, NodeGetCapabilities, NodeGetInfo
• Identity Service: GetPluginInfo, GetPluginCapabilities, Probe

Features:

• Static Provisioning - create persistence volume (PV) from the existing BOS bucket and consume the PV from container using persistence volume claim (PVC).
• Mount Option - mount options could be specified in persistence volume (PV) to define how the bosfs should be run.

Getting Started

These instructions will get you a copy of the project up and running on your environment for development and testing purposes. See installing for notes on how to deploy the project on a Baidu Cloud CCE cluster.

Prerequisites

A health CCE kubernetes cluster. See documents for creating a CCE cluster.

Installing

Prerequisite: Helm

Please read the values.yaml before installation and modify it when needed.
