虽然有一些像我一样的问题，但修复对我不起作用。我正在使用 kubernetes v1.9.3 二进制文件并使用 flannel 和 calico 来设置 kubernetes 集群。应用 calico yaml 文件后，它会卡在创建第二个 pod 上。我究竟做错了什么？日志并不清楚说明出了什么问题
kubectl get pods --all-namespaces
root@kube-master01:/home/john/cookem/kubeadm-ha# kubectl logs calico-node-
n87l7 --namespace=kube-system
Error from server (BadRequest): a container name must be specified for pod
