kubelet无法更新节点状态

Question

kubernetes节点状态报告如下。

root@csp-nso-server78:~# kubectl get nodes 10.213.5.78
NAME          STATUS     AGE
10.213.5.78   NotReady   1h

kubelet日志显示了下面的错误

E0812 11:00:31.626169   10488 kubelet.go:2745] Error updating node status, will retry: client: response is invalid json. The endpoint is probably not valid etcd cluster endpoint.

E0812 11:00:31.972366   10488 kubelet.go:1183] Unable to update node status: update node status exceeds retry count

这似乎与etcd有关。有人能帮上忙吗。

Answer 1

我发布的错误实际上是来自库伯-阿皮瑟弗。

显然，我机器中的kube使用了一个参数‘-etcd-server=http://x.x.x.x:14001’。在我的设置中，ha代理将在14001上侦听，然后将其转发到4001，其中etcd将侦听。

将的init文件更改为使用端口4001直接解决了我的情况下的问题。

目前还不清楚haproxy是如何阻碍沟通的，但现在一切都如期而至。
