Question

我之前已经成功使用“ kubeadm init”部署了一个k8s集群。遇到问题时，我会重新安装k8s。现在，我重新部署了k8s集群失败！

linux操作系统

uname -a
Linux kube-master 4.15.0-33-generic #36-Ubuntu SMP Wed Aug 15 16:00:05 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

k8s env

kubectl version
Client Version: version.Info{Major:"1", Minor:"11", GitVersion:"v1.11.2", GitCommit:"bb9ffb1654d4a729bb4cec18ff088eacc153c239", GitTreeState:"clean", BuildDate:"2018-08-07T23:17:28Z", GoVersion:"go1.10.3", Compiler:"gc", Platform:"linux/amd64"}
The connection to the server localhost:8080 was refused - did you specify the right host or port?

kubeadm version
kubeadm version: &version.Info{Major:"1", Minor:"11", GitVersion:"v1.11.2", GitCommit:"bb9ffb1654d4a729bb4cec18ff088eacc153c239", GitTreeState:"clean", BuildDate:"2018-08-07T23:14:39Z", GoVersion:"go1.10.3", Compiler:"gc", Platform:"linux/amd64"}

我的部署命令：

sudo kubeadm -v 10 init --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=192.168.0.100 --kubernetes-version v1.11.2

[init] this might take a minute or longer if the control plane images have to be pulled

谁可以帮助我？

在kubeadm init之后，您应该将 admin.conf 文件复制到将使用kubectl命令的用户的主目录中，并将配置路径设置为{{1 }}系统变量：

KUBECONFIG

这是一个配置文件，sudo cp /etc/kubernetes/admin.conf $HOME/ sudo chown $(id -u):$(id -g) $HOME/admin.conf export KUBECONFIG=$HOME/admin.conf从中读取与K8s群集建立连接所需的详细信息。
