1、安装kubectl

本地客户端安装kubectl

添加kubernete 阿里云yum源 
# cat > /etc/yum.repos.d/kubernetes.repo << EOF
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF
# yum install -y kubectl-1.20.0

2、集群凭证管理

拷贝主节点凭证信息，路径：/etc/kubernetes/kubelet.conf 或 /etc/kubenetes/kube.conf

 

3、本地客户端配置凭证信息

# mkdir $HOME/.kube
# scp root@<master-public-ip>:/etc/kubernetes/kube.conf $HOME/.kube/config

4、本地客户端验证

[root@elastic ~]# kubectl get nodes
