Fire up Pluto.jl notebook via ssh tunnel

[navidcy]

I'm wondering whether anybody has experience setting up a Pluto.jl notebook via an ssh tunnel. I'd like to open a Pluto.jl notebook on the HPC (which has GPU capabilities) but run the notebook on my local browser. Any help is welcome.

Hi, I've done this, and it works like any normal tunnel.
In the Julia REPL on the server, launch Pluto as

using Pluto
Pluto.run(launch_browser=false)

Then from the client side terminal, you could do
ssh -NfL 1234:127.0.0.1:1234 <username>@hostname
Then open localhost:1234 on your browser

Is there an option to select a different port when launching Pluto.run? (instead of 1234)

[gianmariomanca]

OK, I guessed it and it worked: Pluto.run(port=31808)

Is there a programmatic way to get the secret (example: http://localhost:1234/?secret=R8sEmFW8) of the pluto session running on the remote machine (to avoid having to copy-paste it manually from the remote shell to the local browser) ?

[fonsp]

No, but you can set the secret manually (and use another mechanism to generate and get the secret)

[gianmariomanca]

Great, how do I set the secret manually? I didn't notice any special keyword to manage the secret in Pluto.run(), can you attach an example with the secret set to the string "abcd". (No worries I'll pick something better for the real case :) )

[fonsp]

julia> s = Pluto.ServerSession(; options=Pluto.Configuration.from_flat_kwargs(;port=4567), secret="asdf");

julia> Pluto.run(s)

Opening http://localhost:4567/?secret=asdf in your default browser... ~ have fun!

Press Ctrl+C in this terminal to stop Pluto

Thank you! I'll try it out.

For me, Ctrl + click on the link opened it in my local browser, without needing to copy-paste the link
