failed to run Kubelet: unable to load bootstrap kubeconfig: stat /etc/kubernetes/bootstrap-kubelet

解决方法

备份重新生成证书

# cd /etc/kubernetes/pki/
# mkdir backup
# mv  apiserver.crt apiserver-etcd-client.key apiserver-kubelet-client.crt front-proxy-ca.crt front-proxy-client.crt front-proxy-client.key front-proxy-ca.key apiserver-kubelet-client.key apiserver.key apiserver-etcd-client.crt backup
#重新生成证书如果没有kubeadm-config.yaml可以重新拉取kubeadm配置
#kubectl get cm  -n kube-system kubeadm-config -o yaml >kubeadm-config.yaml
# kubeadm init phase certs all --config=/etc/kubernetes/kubeadm-config.yaml

 

备份并重新生成配置文件

# cd /etc/kubernetes/
# mkdir backup
# mv admin.conf controller-manager.conf kubelet.conf scheduler.conf  backup
# kubeadm init phase kubeconfig all --config=/etc/kubernetes/kubeadm-config.yaml

　

配置config

# cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

　　

重启kubectl

# cd  /var/lib/kubelet/pki/
#删除软连接
# rm  -f kubelet-client-current.pem

# systemctl daemon-reload
# systemctl restart kubelet.service
