Ray Dashboard .yaml is not working

I modified the example-full.yaml file to add the following information:

  • Head IP Address
  • Worker IP Addresses
  • ssh_user

I used the same file to deploy a Ray cluster, which works fine.

If I use that same file on a different machine to start a dashboard so I can submit a job, it fails:

ray dashboard example-full.yaml

Actually, it fails for all ray commands (e.g., exec), but I can connect using python - ray.init(address=head_node_ip_address) from a different machine. What am I doing wrong here?
