我正在使用kind
在本地 Macbook 上运行测试 kubernetes 集群。
我找到了状态为的节点之一NotReady
:
$ kind get clusters
mc
$ kubernetes get nodes
NAME STATUS ROLES AGE VERSION
mc-control-plane Ready master 4h42m v1.18.2
mc-control-plane2 Ready master 4h41m v1.18.2
mc-control-plane3 Ready master 4h40m v1.18.2
mc-worker NotReady <none> 4h40m v1.18.2
mc-worker2 Ready <none> 4h40m v1.18.2
mc-worker3 Ready <none> 4h40m v1.18.2
唯一有趣的kubectl describe node mc-worker
是 CNI 插件没有初始化:

我有 2 个类似的集群,这只发生在这个集群上。
由于kind
使用本地 Docker 守护程序将这些节点作为容器运行,因此我已经尝试重新启动容器(应该相当于重新启动节点)。
我考虑过删除并重新创建集群,但应该有一种方法可以在不重新创建集群的情况下解决这个问题。
以下是我正在运行的版本:
$ kind version
kind v0.8.1 go1.14.4 darwin/amd64
$ kubectl version
Client Version: version.Info{Major:"1", Minor:"16+", GitVersion:"v1.16.6-beta.0", GitCommit:"e7f962ba86f4ce7033828210ca3556393c377bcc", GitTreeState:"clean", BuildDate:"2020-01-15T08:26:26Z", GoVersion:"go1.13.5", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"18", GitVersion:"v1.18.2", GitCommit:"52c56ce7a8272c798dbc29846288d7cd9fbae032", GitTreeState:"clean", BuildDate:"2020-04-30T20:19:45Z", GoVersion:"go1.13.9", Compiler:"gc", Platform:"linux/amd64"}
你如何解决这个问题?
