Error adding a node to Docker UCP

Question

I'm trying to add a node to a fresh UCP install using the copy-paste from the web UI and getting this error on the node:

FATA[0000] The join command is no longer used. To join a node to the swarm, go to the UCP web UI,
      or run the 'docker swarm join' command in the node you want to join.

I'm unable to find any reference to this error or any documentation about 'join' being deprecated.

Answer 1

The join command has been deprecated.

After you have installed UCP, go to Resources -> Nodes -> Create a Node

There you will get a docker swarm join with a Swarm token and manager url. Paste this in the worker/manager node you want to join to the main UCP master.

Otherwise, using the CLI type docker swarm init --advertise-addr <HostName of the manager> command. It will generate a swarm token. Use that in the worker/manager node you want to join to the main UCP master
