How do you go about referencing stacks when using the s3 backend?

you’ll need to dot separate the stacks when you create them

pulumi stack init <http://vpc.dev|vpc.dev>

And then just reference it normally

stack = new pulumi.StackReference('<http://vpc.dev|vpc.dev>')

I separated my stacks into different different sub directories so i guess that approach won't work

you can’t do stack references if you’re using different directories

What benefits does dot-separating the stacks give? or can you link to documentation on it? I’ve been dash separating because i thought the s3 backend didn’t recognize any partitioning characters

just preference, dash separating is fine 🙂
