Facing an error response from daemon

Question

1. I created a docker swarm in the leader machine. So, I got a command in logs that I need to run in the worker machine.so, it will be clustered with leader machine.

2. So, I copied the command and try to execute it in the worker machine. That time I am getting below error and the worker machine is not adding to swarm node.

Command: 

sudo docker swarm join --token SWMTKN-119fpgqx3efsilgcjay4ftx9tgs6f369sitpwmymfk4bdd8k973-82gtevzlcr53ddd5l4vsjr25s 172.31.35.188:2377

Error: Error response from daemon: Timeout was reached before the node joined. The attempt to join the swarm will continue in the background. Use the "docker info" command to see the current swarm status of your node.

Could you please help in resolving this issue?

Answer 1

This error occurs when you try to initiate the swarm using public IP try with the private IP and run that command inside node machine and make sure docker in node machine is in running state that will help you to resolve the issue.

Instead, you can directly use it without any advertising address. That will help you to connect the nodes in the cluster.
