老师您好,通过kubespray部署成功,虚拟机重新启动后,在master节点执行“kubectl get nodes”命令报错,返回“The connection to the server 192.168.66.11:6443 was refused - did you specify the right host or port?”,截图如下。我尝试执行“ctr -n k8s.io run -d -t k8s.gcr.io/kube-apiserver:v1.19.7 api-server”命令创建api-server,但通过“crictl logs api-server”查看日志,还是显示“an error occurred when try to find container “api-server”: does not exist”,这种情况该怎么处理?
