Is there a way to share config between stacks? I know right now there is a per stack config but I am looking to see if there is a way to also have global config that all stacks share in a project.

You can use

StackReference

to inherit values from an upstream stack. Here's an example - https://github.com/pulumi/examples/tree/master/aws-ts-stackreference.

Thanks! I will give that a try.
