The swarm node disappeared after node successfully has joined a few minutes #2824

The node disappeared after node successfully has joined a few minutes.

$ sudo docker --version Docker version 17.09.0-ce, build afdb6d4

At the worker node , sudo docker swarm join . I could see the node ready at the manager node with the command "sudo docker node ls ". But after one minute, the node disappeared. BTW, The manager and the worker node are not in the same Ethernet Subnet, They could be connected with each other.

Steps: master: sudo docker swarm init (172.16.2.x) slave: sudo docker swarm join ... (10.10.x.x)

master and slave are not in same subnet , but could ping each other. Both node have no iptables rules.

The error logs on slave node.

@lh83mail Refered to your logs , this may be a permission problems. However I don't know why docker engine told me "already joined" when I try to re-join swarm node. That means the node was not removed actually ?
