# 阿里云容器服务 K8S Flexvolume 插件

[![Build Status](https://travis-ci.org/AliyunContainerService/flexvolume.svg?branch=master)](https://travis-ci.org/AliyunContainerService/flexvolume) [![CircleCI](https://circleci.com/gh/AliyunContainerService/flexvolume.svg?style=svg)](https://circleci.com/gh/AliyunContainerService/flexvolume) [![Go Report Card](https://goreportcard.com/badge/github.com/AliyunContainerService/flexvolume)](https://goreportcard.com/report/github.com/AliyunContainerService/flexvolume)

针对阿里云云盘、NAS、OSS存储开发的flexvolume 插件，可以支持kubernetes pod 自动绑定阿里云存储服务。

此版本支持Flexvolume, 静态pv. 对于动态pv尚不支持.

## 部署框架
  ![系统框架图](docs/flexvolume.png)

## 安装使用该插件：


通过下面yaml配置进行部署阿里云K8S存储插件，目前支持CentOS 7 操作系统；

**注意：**
> 1. 使用oss数据卷服务时必须配置Secret，如果只使用nas、云盘，则可以不配置Secret；
> 2. 使用flexvolume需要kubelet关闭`--enable-controller-attach-detach`选项。默认阿里云K8S集群已经关闭此选项；
> 3. 在kube-system用户空间部署flexvolume；
