如何解决使用kubespray安装kubernetes总是会失败，这似乎是一个错误
我使用kubespray（v2.11.0）安装kubernetes（1.14.0）。我有三个虚拟机（计划两个主节点，一个节点）。由于网络原因，我使用了内部映像存储库和存储服务器。然后我执行“ ansible-playbook -i库存/mycluster/hosts.yaml --become --become-user = root cluster.yml”命令。第一次，它在节点2上失败。由于任务原因：[kubernetes-apps / network_plugin / flannel：Flannel |等待法兰绒subnet.env文件存在]。错误是等待超时。但我执行“ kubectl获取节点”，我得到了：
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
所以我想可能是我应该将第一个master的文件复制到第二个master节点。
scp node1:/run/flannel/subnet.env node2:/run/flannel
然后我再次执行命令“ ansible-playbook -i库存/mycluster/hosts.yaml --become --become-user = root cluster.yml”。这次所有的任务都还可以。没有失败。但是我仍然无法在kubernetes中获得node2。您可以在下面看到它。

root@node1:~/kubespray# kc get nodes
The program 'kc' is currently not installed. You can install it by typing:
apt install kimwitu
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
root@node1:~/kubespray#
有人告诉我如何解决和调试此问题。
