08/06/2021, 1:04 PMThe advise I tend to give is: logically divide up your resources (networking, databases, application etc) into projects. Stacks should be equivalent to environments, so dev/staging/prod. When it comes to regions, You can use a provider for each region and and then set the provider for the resource

08/06/2021, 1:08 PMSo you'd just have a folder per project and then in each have multiple stack config files where you can specify the differences between each stack. You could also include the regions you want to deploy to in the stack config and have the code build providers based on that

08/06/2021, 1:18 PMThanks @brave-planet-10645 is there any good example showing that setup?

08/06/2021, 1:19 PMWe have this one: https://github.com/pulumi/examples/tree/master/aws-stackreference-architecture
It doesn't have multi-region, and it doesn't have multi stack, but the multi projects is what you're looking for really

08/06/2021, 1:23 PMThanks that looks good.
Are stacks conceptually just an overlay config to apply onto a project?

08/06/2021, 1:27 PMWithout trying to hijack this conversation, I have a related question also... 🙂 How do workspaces fit into this idea? I have a stack that is going to be deployed per feature development for a repo, and I'm trying to figure out how to organize that. So I have two projects (one with shared resources and one with resources that will be deployed every time the request is made), then my stacks will determine environment. How would I organize the project that gets deployed per request? Just with naming conventions? Or should I use workspaces somehow?

08/06/2021, 2:08 PMYou mean TF workspaces?
brave-planet-10645
08/06/2021, 2:08 PMPulumi doesn't have a concept of workspaces

08/06/2021, 2:09 PM@fast-florist-41572 correct
brave-planet-10645
08/06/2021, 2:10 PMOfficially (from the docs):
A stack is an isolated, independently configurable instance of a Pulumi program.f

08/06/2021, 2:11 PMOk thanks, so conceptually I could just use lots of projects to achieve what I want and have a default stack in most cases

08/06/2021, 2:11 PMAwesome, thanks.

08/06/2021, 2:13 PMAlso is there a way to trigger a project that would initiate two other projects/stacks?
fast-florist-41572
08/06/2021, 2:13 PMie, if I had networking and db and then I wanted to have a project that was a region. I call that which would initiate the networking first and then the database

08/06/2021, 2:20 PMNot by default. You should look at our automation api, which allows you to integrate your pulumi programs in an application. In this case you could have an application that would orchestrate your deployments like you've said.
