Is it possible to let the user solve a Captcha as part of a 'pulumi up` ? (for example using Python's

raw_input

function to read from CLI)

I'm not sure you can/should rely on stdin - as you know - the I/O context of your program is pretty tightly controlled by the

pulumi up

UX already. You might be able to - but I suspect the user experience won't be great. That said - you can do any work you want during a

pulumi up

- so you can log a URL and then wait for the user to perform an action at that URL (polling a backend service) if you want.

I think the polling idea is the right way to go, thanks @white-balloon-205 I'm thinking maybe AWS SSM Parameter Store is the right hosting service for that kind of stuff 🧐
