我在用kind测试k8
我创建了集群：
vagrant@vagrant:~$ sudo kind get clusters
nodes-test现在我想用sudo kind delete cluster删除这个集群，但得到：
Deleting cluster "kind" ...
failed to update kubeconfig: failed to lock config file: open /root/.kube/config.lock: read-only file system
ERROR: failed to delete cluster "kind": failed to lock config file: open /root/.kube/config.lock: read-only file system但是当我转到路径时，我看不到文件：
vagrant@vagrant:~$ sudo su
root@vagrant:/home/vagrant# cd /root
root@vagrant:~# cd .kube/
root@vagrant:~/.kube# ls -la

同样，当调用sudo kind delete cluster --name nodes-test命令时，我得到：
vagrant@vagrant:~$ sudo kind delete cluster --name nodes-test
Deleting cluster "nodes-test" ...

当您键入命令以获取群集时，它会列出群集的名称：
所以你的集群名是
nodes-test。但是输入sudo kind delete cluster只会尝试删除默认的集群名称（默认情况下命名为kind）。这也是为什么delete命令显示为Deleting cluster "kind" ...。您需要使用集群名称运行delete命令。您甚至可以在delete命令的文档中阅读这一点如果未指定标志
--name，kind将使用默认的集群上下文名称kind并删除该集群。注意：根据设计，请求删除不存在的群集不会返回错误。这是有意的，并且是具有清理资源的幂等方式的手段。
您需要指定群集名称。试试这个：
sudo kind delete cluster --name nodes-test
