How to implement shared resources in Pulumi

Question

I'm trying to understand how to implement Pulumi in our AWS environment.

I understand that a stack can be used to have the same resource structure for production and development, but that results in independant instances, which is great.

However we also have a shared management VPC where certain tools reside such as pgadmin, gitlab, monitoring tools,...

So what would be the best approach for that?

• Force a stack for that management project (if that is possible)?
• Put a constraint in code so that this management stuff is only deployed in production stack?

Or am I missing the approach of stacks here?

Answer 1

Your first thought is the right way to go. Deploy shared resources in their own stack(s) and use Stack References to share information across stacks.
