05/30/2023, 3:05 PMHi, I'm interested in recent launch of Pulumi commands provider. However, I'm unable to understand few concepts on it from the Docs. Mainly on the purpose of create and delete and whether it is possible to execute custom commands like ls, cat etc. on the created resource (mostly the VM). Can someone help me out

05/30/2023, 3:49 PM@melodic-tomato-39005 Thanks for your reply. I was able to browse through the Internet and find some examples in Python (since I'm much familiar in that). However, I'm hitting with a SSH Handshake problem that I can't figure out how to solve.

05/30/2023, 3:52 PMThis is the sample remote commands setup I'm running in Python. I'm able to connect to this VM from my machine through CLI SSH, however the remote commands failing with the error: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none], no supported methods remain

05/30/2023, 3:52 PMI also copied my ssh public key inside the VM, but still no success

05/30/2023, 3:54 PMFrom whatever, I researched the remote commands should attempt to connect through publickey setup. But why does my attempted methods list only 'none' ?

05/30/2023, 4:02 PMI'm sorry, I should have informed this. I'm trying to connect to a local Ubuntu VM created through pulumi libvirt in Python. The connection arguments are created with the
command.remote.ConnectionArgsbroad-lifeguard-10744
05/30/2023, 4:04 PMAs I told, I have no problem SSH into that VM from my server CLI, and since I've moved by public key also to the authorized list in the VM, it's not asking for password when I SSH through CLI. However,

05/30/2023, 4:12 PMPulumi won’t attempt to use the key because the connection is only configured to use a password (the one you pasted above).
I’m not sure why the password wouldn’t work, though.

05/30/2023, 4:55 PMSo, the attempted methods has only none because I haven't supplied the private key of my server in my connection.
broad-lifeguard-10744
05/30/2023, 4:57 PMYes, that's even I thought when supplying the password. Is there any way to debug the Pulumi remote APIs to see what's happening

05/30/2023, 4:58 PMYou could enable verbose logging as described here.

05/30/2023, 5:12 PMThanks for troubleshooting guide @melodic-tomato-39005. PFA the pulumi up for the above remote command in -v=9 verbose.

05/30/2023, 9:57 PMThese logs confirm that SSH auth is not even attempted but don’t say why. Would you mind opening an issue at https://github.com/pulumi/pulumi-command/issues?

06/03/2023, 2:54 PM@melodic-tomato-39005 Sorry for the delay in response. I've fixed the issue. The problem was with the default SSH configuration that comes with Ubuntu cloud image.
