k8s--报错
1.
[[email protected] kubeconfig]# kubectl get csr
No resources found.
解决
查看master/var/log/messages
--------------------------------------------------------------------------------------------------------------------
2.
kubeconfig]# kubectl create clusterrolebinding kubelet-bootstrap --clusterrole=system:node-bootstrapper --user=kubelet-bootstrap
Error from server (AlreadyExists): clusterrolebindings.rbac.authorization.k8s.io "cluster-admin-binding" already exists
由于残留文件导致无法重新导入集群所以执行：
kubectl delete clusterrolebinding kubelet-bootstrap
sudo kubectl delete clusterrolebindings cluster-admin-binding
进行集群导入到rancher的时候残留配置文件导致导入失败
sudo kubectl get clusterrolebindings cluster-admin-binding -o yaml
