Hi, I’m having some issues with the

StackReference

(trying to understand it). I’m using S3 as backend (everything in one bucket), ideally a folder for each project (micro services setup: infra, app, services, etc). With this I saw two options: 1. Every pulumi project in same folder -> each stack needs to have project name in it (eg,

infra.dev

), or they will collide (dev, in two different projects, in same folder in S3). 2. Every project in different folders -> stack can be named with just the environment (

dev

,

stg

,

prod

) In case 1, I did

new StackReference('infra.dev')

, and it ends with error:

aws:lambda:Function (lambda_name):
    error: 1 error occurred:
    	* error creating Lambda Function (1): ValidationException:
    	status code: 400, request id: 6dab7a4b-c6cc-4ebc-8a46-cb14060d50f2

Apparently it gets the stack_reference but it fails to deploy. My assumption is because it’s empty data or failing in some level with those refs. Also tried

new StackReference('project_name/infra.dev')

, but got the error:

error: Preview failed: unknown stack "project_name/infra.dev"

If I wanted to use the case 2, everything in different folders, how do you reference to the other stack? Any help is more than welcome.

each project should have its own directory then stack reference path is

org/project/stack

@great-sunset-355 thanks for the response. But, I read that with S3 as backend,

org

is not defined. Or do you know how to get it? Also, with different paths (folders within the same bucket), tried to reference as

project/stack

. But got

unknown stack

, or something of the sort.

hmm I see, check out the structure of this project, it's pretty big and complex it may give you an answer https://github.com/mitodl/ol-infrastructure/blob/f42b329df70b4ec7c59295e0e011100a61775472/src/ol_infrastructure/infrastructure/mongodb/__main__.py#L28

Thanks! I’ll check that

I thought it wasn't possible to use StackReferences to stacks in a different file? That is, if you're using an S3 backend, everything has to have the same

backend

URL?

@little-cartoon-10569 are those questions, they sound like affirmations. From my limited testing, I couldn’t find a way for a given project to get a StackReference on a stack on a different folder. The only working model I could make, was with all the stacks on the same folder.
