使用rancher自带的kubeconfig的方法如 [https://blog.csdn.net/vah101/article/details/90789540][https_blog.csdn.net_vah101_article_details_90789540] 所示

本文讨论在不经过rancher UI手动生成kube config的方法：

首先，下载kubectl文件，执行如下命令，其中local为之前创建集群是采用的名称：

cd /etc/kubernetes/ssl/
    kubectl config set-cluster local --certificate-authority=kube-ca.pem --server=https://192.168.10.100:6443
    kubectl config set-credentials local --client-certificate=kube-scheduler.pem --client-key=kube-scheduler-key.pem
    kubectl config set-context local --cluster=local --user=local
    kubectl config use-context local

之后执行cat /root/.kube/config，可以看到：

apiVersion: v1
    clusters:
    - cluster:
        certificate-authority: /etc/kubernetes/ssl/kube-ca.pem
        server: https://192.168.10.100:6443
      name: local
    contexts:
    - context:
        cluster: local
        user: local
      name: local
    current-context: local
    kind: Config
    preferences: {}
    users:
    - name: local
      user:
        client-certificate: /etc/kubernetes/ssl/kube-scheduler.pem
        client-key: /etc/kubernetes/ssl/kube-scheduler-key.pem

最后执行kubectl get node看到输出结果，说明成功：

NAME             STATUS   ROLES                      AGE    VERSION
    192.168.10.100   Ready    controlplane,etcd,worker   112d   v1.14.8
    192.168.10.101   Ready    controlplane,etcd,worker   112d   v1.14.8
    192.168.10.102   Ready    controlplane,etcd,worker   112d   v1.14.8
