Problem adding a worker to the swarm

Posted June 5, 2020 4.4k views

I have 2 nodes, node1 and node2. No firewall.

CMD0 - docker swarm init –advertise–addr ip_node1

CMD1 - docker swarm join–token SWMTKN… ip_node1:2377
“Error response from daemon: Timeout was reached before 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.“

CMD2 - docker info
"Swarm: error
Error: rpc error: code = DeadlineExceeded desc = context deadline exceeded
Is Manager: false
Node Address:”“

In /var/log/syslog
msg="failed to retrieve remote root CA certificate”

I made
CMD3 - systemctl show –property=Environment docker

I tryed CMD1 and it gave me the same error,could someone please tell me what I am doing wrong?

I’ve had a similar issue in the past, what I did wrong back then was that I used an incorrect IP address when running the docker swarm init --advertise-addr your_dorplet_ip_here command.

I would recommend running the command again and see how it goes.

Another thing that I could suggest is again making sure that you don’t have a firewall like ufw enabled which could be causing that problem for you.
