Ray: How can I connect to the dashboard of a cluster on AWS from my pc?

[aefn]

Dear Experts,
I didn't know how to run the auto scaler on AWS. For this reason I asked one of my colleagues to deploy the cluster for me on AWS. He gave me the ip address of the head node and the key for ssh. I don't have access to him until Tuesday and I need your help.
Now I can ssh to the head server but I don't know how can I see the dashboard remotely.
I have seen the command ray dashboard but I couldn't figure out how to use it.
let say that I have the public ip of the head node and also I can ssh to it.
How should I use this cluster now?
I appreciate your help in advance.

I should mention that I used this: <public ip of head node>:8265 but nothing comes up

@aefn you can run 'ray dashboard' to forward the port to your local machine. While it's running, open localhost:8265 in your browser to view the dashboard.

@edoakes could you please give me an example?
the signature of ray dashboard is like this ray dashboard [OPTIONS] CLUSTER_CONFIG_FILE

as I said I don't have that CLUSTER_CONFIG_FILE, I just have the ip of head node and I can ssh to it.
now I would appreciate if you could guide me what can I do with these to open the dashboard in my pc locally.

CLUSTER_CONFIG_FILE is needed to deploy Ray using an autoscaler. Can you ask your colleague to provide a cluster config file and try using ray dashboard?

I can but I need to wait until Tuesday. There is not any other way to doing that. For example with doing some trick with ssh?

We implemented this through port forwarding. You can probably take a look at this code. https://github.com/ray-project/ray/blob/d8a081a185271cf9fa352f7ae2c93abdbef6858a/python/ray/autoscaler/updater.py#L244

It seems like it just runs a ssh command.
Can you try ssh -L "[remote_port]:localhost:[local_port]"?

Sorry. It has several more options. Let me figure out the command and get back to you.

I think it must be this => ssh -L "[remote_port]:localhost:[local_port]" -i [private key] [user]@[ip].

@aefn Did it work? Let me know how it works!

I think it will work, but another big problem is raised for me. The node is unreachable, I don't know what happened but I think now I have to wait until Tuesday :((
I will give you the feedback when I can test it.
Btw, thank you again for your help.
