Ansible 使用kubespray安装kubernetes总是失败，这看起来像一个bug

我使用kubespray（v2.11.0）安装kubernetes（1.14.0）。我有三个vm。（计划两个主节点，一个节点）。由于网络原因，我使用了内部映像repo和存储服务器。然后我执行“ansible playbook-i inventory/mycluster/hosts.yaml--been--been-been user=root cluster.yml”命令。第一次，它在node2上失败。因为任务：[kubernetes apps/network_plugin/flannel:flannel |等待flannel subnet.env文件存在]。错误是等待超时。但我执行“kubectl获取节点”我得到：

root@node1:~/kubespray# kubectl get nodes
NAME    STATUS   ROLES    AGE   VERSION
node1   Ready    master   22h   v1.14.0
node3   Ready    <none>   69m   v1.14.0

然后我再次执行命令“ansible playbook-i inventory/mycluster/hosts.yaml--been--been user=root cluster.yml”。这一次所有的任务都很好。没有错。但我还是没能在库伯内特斯拿到2号。你可以在下面看到
