Hello! I copied pulumi code from one directory to another, and now it doesn't seem to want to

pulumi up

$ pulumi up -d

What's going on here?

ouch! I’ve tried to hammer down the bug where it doesn’t print out a useful error message but it apparently keeps cropping up… Is the

pulumi

package available to the

python

on your

PATH

? That seems to me to be the most common cause of this issue.

New version didn't help

oh, absolutely! It’s a bug I keep trying to track down that we don’t print anything useful when

import pulumi

throws…

t3.micro

didn't work either

what’s your full code?

Let me toss it up in github

thanks!

While I have you...

So - the Pulumi engine is capable of parallelizing deletions, but it currently doesn’t for Python programs because Python previously didn’t support the machinery that the engine needed in order to safely parallelize operations. Python does support it now, so we basically can turn it on whenever we want, but we haven’t yet because it has the potential to break programs written using the “old” versions of the Python SDK. So to answer your question, 1) it’s sort of by design, for safety reasons and 2) we can trivially turn it off and parallelize deletions, once we’re sure that everyone has reasonably migrated to the new python SDK

Okay, glad it's coming!

Regarding docs - that’s a top priority for me in the current milestone ending January 20. That said, we know our docs are generally deficient and we’re going to be working hard on them in the coming months - it’s especially bad for Python, since there are basically zero useful docs on the website. Would it help if we had more Python examples in the meantime?

Yes, more examples and more docs would be great.

awesome!

I'd like some general guidance on: - go about writing your pulumi python this way - don't do these things

yeah, makes sense

Understand, I'd just rather not bring something to you guys and then you think I'm doing something totally stupid 🙂

you’re absolutely not doing anything stupid, but I get the sentiment 😄

How do the other languages pulumi supports fit into the maturity scale?

TypeScript/JavaScript is far and away the most mature, followed by Python, followed by Go.

Good to know.

okay, so I think what’s going on with your code sample is that the

get_linux_ami

function hasn’t been updated to support

t3

sizes

yeah, it came from examples. And now I feel dumb for not realizing that was coming from a dictionary/map.

no problem! i hope it goes without saying but feel free to ping me anytime if you have any problems 😄

What about my exports issue?

what sort of “not work” are you seeing? not seeing any stack exports? your program crashes?

So, I have the export in the loop

cool!

Thanks for all the help!

no problem!
