可通過命令快速添加 #相關(guān)文件參數(shù)從/root/.kube/config獲取

# 創(chuàng)建文件夾
mkdir -p /root/.cluster1/
## 添加cluster
kubectl config set-cluster cluster1 --server=https://ip:6443 --certificate-authority=/root/.cluster1/ca.crt
## 添加user
kubectl config set-credentials cluster1 --client-certificate=/root/.cluster1/client.crt --client-key=/root/.cluster1/client.key
## 添加context
kubectl config set-context cluster1 --cluster cluster1 --user=cluster1

加入集群

kubefedctl join <集群名稱> --cluster-context <要接入集群的 context 名稱> --host-cluster-context <HOST 集群的 context> kubefedctl join cluster1 --cluster-context cluster1 \--host-cluster-context cluster1 --v=2 #這里把一個主集群加入到自身

如果命令添加context join失敗，執(zhí)行

kubectl config delete-context cluster1

然后手動修改/etc/kubernetes/admin.conf相關(guān)參數(shù)

獲取集群的連接信息

kubectl config get-contexts

?查看加入集群信息

[root@ai-k8s-master kubernetes]# kubectl -n kube-federation-system get kubefedclusters
NAME ? ? ? AGE ? READY
cluster1 ? 39m ? True
