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 NAME STATUS ROLES AGE VERSION vm-16-12-ubuntu Ready <none> 114d v1.21.14 vm-16-19-ubuntu Ready <none> 114d v1.21.14 vm-16-2-ubuntu Ready <none> 114d v1.21.14 vm-16-21-ubuntu Ready <none> 25d v1.21.14 vm-16-3-ubuntu Ready <none> 114d v1.21.14 vm-16-36-ubuntu Ready <none> 16d v1.21.14 vm-16-47-ubuntu Ready <none> 114d v1.21.14 vm-16-9-ubuntu Ready control-plane,master 114d v1.21.14
