如何修复“错误：“kubectl”的未知命令“join””

我尝试使用 kubectl join 命令将工作节点加入 Kubernetes 集群。尝试通过运行以下命令来解决该问题。

要解决此问题，您需要更新 kubectl 命令行工具以匹配 Kubernetes 集群的版本。

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/arm64/kubectl"

下载最新版本的 kubectl 后，您需要使其可执行并将其移动到 PATH 中的某个位置：

chmod +x kubectl
sudo mv kubectl /usr/local/bin/kubectl

命令下面的新建议方法也不起作用。

sudo snap install kubectl --classic

要查看系统上安装的当前 Kubernetes 版本，可以使用 kubectl version 命令。

ubuntu@master:~$ sudo kubectl version

您运行了错误的命令；要将节点加入集群，您需要使用kubeadm join。注意，不是。kubeadmkubectl
