无法更新Kops群集-DNS查找错误 [英] Unable to update kops cluster - DNS lookup error

问题描述

在为"kubernetes.xxxx.xxx"的NS记录执行DNS查找时出错:在10.0.2.3:53上查找kubernetes.xxxxxxxx.xxx:读取udp 10.0.2.15:56154->10.0.2.3:53:I/o超时

error doing DNS lookup for NS records for "kubernetes.xxxx.xxx": lookup kubernetes.xxxxxxxx.xxx on 10.0.2.3:53: read udp 10.0.2.15:56154->10.0.2.3:53: i/o timeout

只有我的kops更新集群抛出以下所有其他命令，看起来很好

only my kops update cluster throws the following all other commands looks fine

这是我的kops验证集群

here is my kops validate cluster

使用来自kubectl上下文的集群:kubernetes.xxxx.xxx

Using cluster from kubectl context: kubernetes.xxxx.xxx

验证集群kubernetes.xxxxxx.xxxx

Validating cluster kubernetes.xxxxxx.xxxx

实例组名称角色机器类型最小最大子网 master-xxx-xxxx-1a Master t2.micro 1 1 xx-xxxxx-1a 节点节点t2.micro 2 2 xx-xxxxxx-1a

INSTANCE GROUPS NAME ROLE MACHINETYPE MIN MAX SUBNETS master-xxx-xxxx-1a Master t2.micro 1 1 xx-xxxxx-1a nodes Node t2.micro 2 2 xx-xxxxxx-1a

节点状态名称角色已准备就绪 ip-xxxx-xx-xx-xxx.xxx-xxxxx-x.compute.internal master True

NODE STATUS NAME ROLE READY ip-xxxx-xx-xx-xxx.xxx-xxxxx-x.compute.internal master True

验证失败的就绪主节点1个，共1个.就绪节点0个，共1个 2.

Validation Failed Ready Master(s) 1 out of 1. Ready Node(s) 0 out of 2.

您的节点尚未就绪kubernetes.xxxxxx.xxx

your nodes are NOT ready kubernetes.xxxxxx.xxx

推荐答案

这是DNS问题.我对名称服务器进行了nslookup并将IP添加到/etc/resolv.conf文件

It's a dns issue. I did a nslookup to my name servers and added the IP's to /etc/resolv.conf file

nameserver 10.0.2.3
nameserver xxx.xxx.xxx.xxx
nameserver xxx.xxx.xxx.xxx
nameserver xxx.xxx.xxx.xxx
nameserver xxx.xxx.xxx.xxx
search xxxxxx
search kubernetes.xxxxxx.xxx

，当我运行kops时，现在更新群集.它解决了这个问题.

and when i ran kops update cluster now. It fixed the issue.
