I'm having an issue with starting up an Rstudio docklet, where my R session crashes out every time. I run the code below:

library(analogsea)

droplet_create(region="lon1", image="ubuntu-16-04-x64")

d <- droplets()[[1]]

docklet_rstudio(d, user="test", password="test123", verbose=TRUE)

Everything is fine until the last step. I have tried both with the ssh branch, as well as with the latest development branch (and I can't figure out the ssh details with the CRAN release). The last step first pulls up the password entry dialog box (I have also tried simply adding the password as an input argument and get the same error) with verbose=TRUE gives me the following output

docker pull rocker/rstudio Found known server key: 2b:82:bd: ....

But after a couple of seconds, R always crashes. I have also tried also running Rgui, and I get the same issue, so it doesn't appear to have anything to do with RStudio specifically.

I'm not quite sure how to even start to debug the issue since I can never get any traceback. Any help would be very much appreciated. Happy to run any diagnostics you might need.

thanks very much for the report @mathesong

the ssh branch is behind master now, it's stuff has been merged into master. so master is the current thing to use.

my first gut reaction is that you created a regular droplet (droplet_create) then tried to use it to do docker stuff. you should try docklet_create(), then use that to pass to docklet_rstudio. try docklet_create and the rest of the code, and report back

[mathesong]

Thanks so much for the quick response!

Re ssh branch: I encountered the same issue with both the ssh branch and the most recent master branch. But I'll stick to the latest branch for now then.

Thanks for putting me right on my using droplet_create() instead of docklet_create(). That was silly of me. I hoped that might fix it, but unfortunately the problem persists. I'm now running the following:

library(analogsea)

docklet_create(region="ams3", image="ubuntu-16-04-x64")

d <- droplets()[[1]]

docklet_rstudio(d, user="test", password="test123", verbose=TRUE)

In each case, I enter the passphrase, wait a few seconds, and then R crashes as before.

EDIT: ran again with debug. The crash occurs at docklet_pull()

[sckott]

thanks for the details @mathesong

@jeroen seems maybe askpass is involved here? anything we can do to try to debug?

[mathesong]

I realised I was being a bit daft and should really have been stepping through everything a bit more carefully using debug. I've managed to follow the trail of the error a bit further, and isolated it to an issue within ssh::ssh_connect() at the following line

    .Call(C_start_session, details$host, details$port, details$user, 
        keyfile, passwd, verbose)

This is the point at which the crash happens.

I see that this actually falls outside of analogsea. @sckott If you want I can close the issue, and move it over to the ssh repo?

[jeroen]

Yes please open an issue in the ssh repo. Is there a way I can reproduce this? Maybe you can try debug(ssh::ssh_connect) to see for which values it crashes? Also try setting verbose=5 in ssh::ssh_connect so that we get some more info about which point it crashes at.

[mathesong]

Thank you both for your time and the help. I've started a new issue in the ssh package repo.
