如何在宿主机上操作Rancher2部署的K8S集群

在遇到这个问题之后，我曾在微信群里面咨询过，得到了一个大致的方向，但是网上的文章都有些问题，现给出一个可行解决方案
1.首先安装kubectl，安装kubectl有多种方法，我这里给出一个我认为最简单的方法

[root@180730-wuguozhu-rancher-1 ~]# curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
[root@180730-wuguozhu-rancher-1 ~]# chmod +x ./kubectl
[root@180730-wuguozhu-rancher-1 ~]# sudo mv ./kubectl /usr/local/bin/kubectl

2.创建kube配置目录

[root@180730-wuguozhu-rancher-1 ~]# mkdir ~/.kube
[root@180730-wuguozhu-rancher-1 ~]# cd .kube/

3.获取config文件内容

4.在~/.kube下创建config文件

[root@180730-wuguozhu-rancher-1 ~]# vim .kube/config
#内容如下：
apiVersion: v1
kind: Config
clusters:
- name: "k8s1"
  cluster:
    server: "https://192.168.108.45/k8s/clusters/c-crhfd"

保存退出
5.验证

[root@180730-wuguozhu-rancher-1 .kube]# kubectl get pod
NAME                            READY     STATUS    RESTARTS   AGE

完成！
