k8s集群搭建报错：error：kubectl get csr No resources found.

问题

kubectl get csr
No resources found.

原因

因为原来的ssl证书在重启后失效了，不删除的话，即重启kubelet也无法与master通讯

解决方法

node节点

cd /opt/kubernetes/ssl
ls
kubelet-client-2021-04-14-08-41-36.pem  kubelet-client-current.pem  kubelet.crt  kubelet.key
# 删除所有的证书
rm -rf *
# 关闭开启的kubelet
systemctl stop kubelet

master01

kubectl delete clusterrolebinding kubelet-bootstrap
clusterrolebinding.rbac.authorization.k8s.io "kubelet-bootstrap" deleted

kubectl create clusterrolebinding kubelet-bootstrap --clusterrole=system:node-bootstrapper --user=kubelet-bootstrap
clusterrolebinding.rbac.authorization.k8s.io/kubelet-bootstrap created

node节点

#开启kubelet
#node01
bash kubelet.sh 192.168.238.82
#node02
bash kubelet.sh 192.168.238.83

测试成功

master01

kubectl get csr
NAME                                                   AGE   REQUESTOR           CONDITION
node-csr-mJwuqA7DAf4UmB1InN_WEYhFWbQKOqUVXg9Bvc7Intk   4s    kubelet-bootstrap   Pending
node-csr-ydhzi9EG9M_Ozmbvep0ledwhTCanppStZoq7vuooTq8   11s   kubelet-bootstrap   Pending

成功！！！
