来自守护进程的错误响应：rpc错误：code = 2 desc =群中没有领导者

我已经使用docker-machine创建了3个节点swarm群Virtualbox。三个都在运行，我可以使用'docker-machine ssh'来连接每一个。有一个问题，我重新启动物理机器并且集群似乎无法工作，为什么？以下是详细信息。感谢您的指导和建议。来自守护进程的错误响应：rpc错误：code = 2 desc =群中没有领导者

[email protected]:~$ docker-machine ls
NAME  ACTIVE DRIVER  STATE  URL       
SWARM DOCKER  ERRORS 
first -  virtualbox Running tcp://192.168.99.100:2376   
v17.06.0-ce 
second -  virtualbox Running tcp://192.168.99.101:2376   
v17.06.0-ce 
third -  virtualbox Running tcp://192.168.99.102:2376   
v17.06.0-ce 
The first is a leader and the second is a manager while the third is a worker.I tried to use 'docker-machine ssh first docker node ls'.

Error response from daemon: 

`rpc error: code = 2 desc = The swarm does not have a leader`. 

It's possible that too few managers are online. Make sure more than 
half of the managers are online. 
exit status 1

我怎么能解决这个问题，并使用

docker node ls

on manage node？非常感谢您的建议。

我也想知道为什么会发生，如果你知道答案，请填写感觉给我一个评论。 –

我有同样的问题，但我不知道是什么原因造成的。我能够通过输入来修复它：

docker swarm init --force-new-cluster

一切都恢复了。我希望这也适用于你
