我用的是kubespray（v2.11.0） install kubernetes（1.14.0）。我有3个vm。（计划2个master，1个节点）由于网络原因，我使用了内部的image repo和storage server。然后我执行“ansible-playbook -i inventory/mycluster/hosts.yaml --become --become-user=root cluster.yml”命令。第一次，它在node2上失败了。因为任务：[kubernetes-apps/network_plugin/flannel : Flannel | 等待 flannel subnet.env 文件存在]。错误是超时等待。但我执行“kubectl get nodes”我得到了这个：
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
所以我认为可能我应该将第一个 master 的文件复制到第二个主节点。
scp node1:/run/flannel/subnet.env node2:/run/flannel
然后我再次执行命令“ansible-playbook -i inventory/mycluster/hosts.yaml --become --become-user=root cluster.yml”。这次所有的任务都ok了。没有失败。但我仍然无法在 kubernetes 中获取 node2。您可以在下面看到。

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

有人告诉我如何解决和调试这个问题。
