大量证书已过期

Question

我从docker开始，当我尝试此命令时：

$ docker service list

在我的服务器上，我收到此错误消息

*Error: Swarm certificates have expired. To replace them, leave the swarm and join again*.  

正如错误所言，我必须离开大群并再次加入。但是问题是我没有蜂群的令牌，地址和端口。我也不知道哪个节点是群管理器。命令

$ docker info
 gives me the following output :

有人可以告诉我如何解决大量证书过期的问题，或者如何从工作节点中获取群集令牌，Ip地址和端口？注意：几乎所有docker swarm swarm命令都给我相同的错误：

Error: Swarm certificates have expired. To replace them, leave the swarm and join again.

Answer 1

离开群后使用

$ docker swarm leave

总是可以从集群管理器节点获取join命令，而无需重新创建整个集群。命令docker swarm join-token将为您提供所需的命令：

$ docker swarm join-token worker
To add a worker to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-0g9sxv0seaovqakgmyobizjhqgazmhra4gn5lnjpczzscfmxpv-ct131a54ghh2igx6v1st0txw4 192.168.65.3:2377

$ docker swarm join-token manager
To add a manager to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-0g9sxv0seaovqakgmyobizjhqgazmhra4gn5lnjpczzscfmxpv-65otgvl9wm9w3h5agq3wvei4u 192.168.65.3:2377
