度量-服务器:节点没有匹配类型的地址[InternalIP]
度量-服务器:节点没有匹配类型的地址[InternalIP]
提问于 2021-05-19 11:58:45
我使用Rancher 2.5.8来管理我的Kubernetes集群。今天，我创建了一个新的集群，除了度量服务器之外，一切都按预期运行。度量-服务器的状态总是"CrashLoopBackOff“，日志告诉我如下：

这是kubectl get nodes worker1 -oyaml的输出
status:
addresses:
- address: worker1
type: Hostname
- address: 65.21.<any>.<ip>
type: ExternalIP回答 1

问题在于度量服务器。
度量服务器配置为使用kubelet-preferred-address-types=InternalIP，但工作节点没有列出任何InternalIP：
$ kubectl get nodes worker1 -oyaml:
[...]
status:
addresses:
- address: worker1
type: Hostname
- address: 65.21.<any>.<ip>
type: ExternalIP解决方案是在度量服务器部署yaml中设置--kubelet-preferred-address-types=ExternalIP。
但是，更好的解决方案可能是像官方度量服务器部署yaml (来源)那样配置它：
- --kubelet-preferred-address-types=InternalIP,ExternalIP,Hostname度量-服务器配置文档中的As状态
-kubelet-首选地址-类型-在确定连接到特定节点的地址时使用的节点地址类型的优先级(默认主机名、InternalDNS、InternalIP、ExternalDNS、ExternalIP)
