「Kubernetes」- failed to get azure cloud in GetVolumeLimits

  CREATED BY JENKINSBOT

问题概述

启动systemctl start kubelet.service服务后,在日志中出现如下错误消息:

Aug 27 11:09:20 node1 kubelet[1188]: E0827 11:09:20.083185    1188 azure_dd.go:147] failed to get azure cloud in GetVolumeLimits, plugin.host: node1
Aug 27 11:09:30 node1 kubelet[1188]: E0827 11:09:30.108157    1188 azure_dd.go:147] failed to get azure cloud in GetVolumeLimits, plugin.host: node1
Aug 27 11:09:40 node1 kubelet[1188]: E0827 11:09:40.122239    1188 azure_dd.go:147] failed to get azure cloud in GetVolumeLimits, plugin.host: node1

大概五秒钟一次,本文将介绍如何处理该错误。

系统环境

操作系统: CentOS Linux release 7.4.1708 (Core)
Kubernetes: v1.12.1

问题原因

报错的是AttachVolumeLimit插件,这个插件用于报告可以附加到节点的卷数限制,因为Google,Amazon,Microsoft等云商通常对可以连接到节点的卷数量进行限制。 对于Kubernetes来说,反映这些限制很重要。否则,调度到节点上的Pod可能会因为等待卷挂载而卡住。

但是,我们是自己部署的集群,没有云商的限制,所有可以禁用它。

解决办法

修改/etc/sysconfig/kubelet配置文件,添加--feature-gates=AttachVolumeLimit=false选项。
