K8s-kubectl远程管理集群

在实际工作中，我们有一个需求，需要远程登陆管理集群。其实不用非要登录k8s-master去敲命令，可以使用任意一台内网互通的机器安装kubectl命令，去远程管理集群，非常方便

### 1.安装kubectl ###

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=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
    
    #重建yum缓存，输入y添加证书认证
    yum makecache fast

yum install -y  kubectl-1.18.4 
    #安装集群管理命令

### 2.查看master节点的集群配置文件 ###

cat .kube/config

### 3.在远程管理机器上创建配置文件 ###

mkdir -p $HOME/.kube
    vim .kube/config

拷贝master节点的配置文件或者scp过去都行

**注意一点 我这里是内网互通环境，用域名的记得配置hosts主机解析，没有尝试过外网ip效果，小伙子们可以试试！**
