Centos 7 kubectl 客户端连接rancher里面的k8s

1 centos7 安装最新版本的kubectl

脚本如下：install_kubectl.sh

#!/bin/bash

# make sunny sunnylinux@foxmail.com

cat <<EOF > /etc/yum.repos.d/kubernetes.repo

[kubernetes]

name=Kubernetes

baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64

enabled=1

gpgcheck=1

repo_gpgcheck=1

gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg

EOF

sleep 5

yum install -y kubectl kubelet kubeadm

systemctl enable kubelet

systemctl start kubelet

2 获取rancher上面的k8s集群的config文件

进入rancher的k8s集群页面：

点击右上角的Kubeconfig文件复制保存

在客户端的主机上面新建文kube的文件夹

[root@localhost ~]# mkdir -p /root/.kube/

root@localhost ~]# cd /root/.kube/

把刚才复制保存的config文件放到下面对应的路径下

[root@localhost ~]# vi config

[root@localhost .kube]# ls

cache  config

[root@localhost .kube]#

执行kubectl get nodes

[root@localhost .kube]# kubectl get nodes
