kubernetes 集群证书过期处理

查看证书到期时间

kubeadm alpha certs check-expiration

修改时间使证书暂时有效

date -s '0000-00-00'

重新分发证书

kubeadm alpha certs renew all

重启服务，重载证书

docker ps | grep -v pause | grep -E "etcd|scheduler|controller|apiserver" | awk '{print $1}' | awk '{print "docker","restart",$1}' | bash
ntpdate pool.ntp.org

更新用户配置

cp /etc/kubernetes/admin.conf ~/.kube/config
