kubectl-config 命令

常用示例

说明

kubectl config manages kubeconfig files, which store the connection details, credentials, and preferences needed to interact with Kubernetes clusters. A kubeconfig defines three list-shaped sections: clusters, users, and contexts, where each context binds a cluster, a user, and an optional default namespace. By default kubectl reads `~/.kube/config`. The loading order is the explicit --kubeconfig flag, then the colon-separated paths in the KUBECONFIG environment variable, then `~/.kube/config`. When KUBECONFIG lists multiple files, they are merged in order, with earlier files winning conflicts. The subcommands let you inspect the merged view, switch between contexts to target different clusters, set per-context defaults such as the namespace, and add or remove cluster, user and context entries.
