集群升级kubelet版本高于kube-apiserver版本
Xiaolei1091058519 opened this issue · comments
What happened?
集群版本是1.22.5-00版本，我这边将节点kubelet版本升级到1.23.17-00版本，按照官方文档中的说明，kubelet版本不能高与kube-apiserver版本（1.22.5-00），可是我的节点还是正常可以创建pod资源。节点kubelet日志无异常。目前不确定这样问题出在哪儿，哪位大神可以帮我解答一下。

What did you expect to happen?
kubelet版本高于kube-apiserver版本，会出现节点notready或者是创建pod资源失败的情况。
How can we reproduce it (as minimally and precisely as possible)?
集群是1.22.5-00版本，其中一个node节点kubelet升级到1.23.17-00版本。
Anything else we need to know?

@Xiaolei1091058519
Can you please describe the issue in primary language(English)?
@T-Lakshmi The cluster version is version 1.22.5-00. Upgrade the kubelet version of one of the nodes to version 1.23.17-00. According to the instructions in the official documentation, the kubelet version（1.23.17-00） cannot be higher than the kube-apiserver version (1.22.5-00). But currently my node can create pod resources normally. There are no exceptions in the node kubelet logs.
