我正在尝试在 CentOS 7.3 服务器上安装 Kubernetes 集群。在取得一些进展后，我被困在安装 CNI 插件上。要安装插件，我需要传递一个从“kubectl version”命令输出中提取的参数。但是命令在获取所需信息时出错，服务器版本:
[root@bigdev1 ~]# kubectl version
Client Version: version.Info{Major:"1", Minor:"6", GitVersion:"v1.6.0", GitCommit:"fff5156092b56e6bd60fff75aad4dc9de6b6ef37", GitTreeState:"clean", BuildDate:"2017-03-28T16:36:33Z", GoVersion:"go1.7.5", Compiler:"gc", Platform:"linux/amd64"}
Error from server (NotFound): the server could not find the requested resource
实际上，我开始使用 kubeadm 1.7.3(和 Docker 17)版本的默认文档(https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/)，但在检查时卡住了:
[root@bigdev1 ~]# kubeadm init --pod-network-cidr=10.244.0.0/16

(永远等在这里)
然后我将 Docker 版本降低到 1.12.6，将 kubernetes 版本降低到 1.6.0 修改 kubeadm 配置后。也停止将 cidr 参数传递给 kubeadm init。
如果您能提出任何解决此问题的建议或给出以下命令的结果，我将很高兴:
kubectl 版本 | base64 | tr -d '\n'
提前致谢。
最佳答案
不确定您关注的是哪个文档。我建议使用 kubeadm 来配置集群。

关于linux - kubectl 版本返回错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45860343/
