    参考链接：Command line tool (kubectl) | KubernetesKubernetes provides a command line tool for communicating with a Kubernetes cluster's control plane, using the Kubernetes API.This tool is named kubectl.For configuration, kubectl looks for a file named config in the $HOME/.kube directory. You can specify other kubeconfig files by setting the KUBECONFIG environment variable or by setting the --kubeconfig flag.This overview covers kubectl syntax, describes the command operations, and provides common examples.
