@here can anyone tell me if there is a supported way to do a stack reference across different pulumi projects? Specifically we are using the AWS S3 backend and each project is in a new directory. Pulumi login though only logs into the active project, I would need to get shared resources from a different one.

When you create a stack reference, you're calling it as

<org>/<project>/<stack>

. So if you're in an org called "abc" and the projects are "123" and "456" with stacks called "dev", you can call the stack details from "123" in "456" like this (this is in Python):

from pulumi import StackReference

ref123 = StackReference(f'abc/123/dev')
ref123_output = ref123.get_output("ref")

how do I find out our org?

Not sure if stack references work on S3 backend.

You're using the s3 backend so you actually don't have

org

...

thats the concern so say I have s3://bucket/project1

yah if you're logging into them separately with

pulumi login

I don't think

StackReference

will work. There are more details around this issue here: https://github.com/pulumi/pulumi/issues/2814

no im not

(IE: cant have two stacks named dev)

For S3 backend it is recommended to include the project name in the stack name to avoid this issue and to keep all stacks in the same bucket (this will allow StackReference) i.e.

myproject-dev

and

other-project-dev

in one s3 bucket will allow StackReference

ok I was afraid of that...it would be nice if you could specify for the s3 provider like a relative path

../

or similar so you could get at other projects. Of course this isn't a problem with the pulumi console solution.

Let's say we have s3://bucket/.pulumi/stacks/Pulumi.Project1-dev.yaml and s3://bucket/.pulumi/stacks/Pulumi.Project2-dev.yaml . How could Project2 stackreference Project1 and what would its syntax be? cause the <org>/<project>/<stack> hierarchy does not exist here
