Hello! Is there a way to use multiple config files per stack?

Depends on what you're really asking. Stack configuration files are tightly coupled with a stack. However, if you're asking for "global" configuration, then yes, you can share common configuration across stacks using

Pulumi.yaml

. Otherwise, you'll likely have to use your general purpose language's patterns for configuration.

thanks for the response @millions-furniture-75402 Let’s for example, assume I have

staging

stack with the corresponding

Pulumi.staging.yaml

file. is there a way to have several files for the same stack?

Are we clear on terminology? A Pulumi project is the resource graph "plan" A stack is an instance of that project, which should have its own configuration and outputs. You can make 100 stacks for 1 Project if you want, and the only thing different is the

Pulumi.<stackname>.yaml

.

Thanks, I’m familiar with the terminology, I just have a stack with a lot of resources and I just want to split the configuration yaml of these resources into several files ( all related to the same stack )

Is any of these shared configuration?

what do you mean?

Can you tell me more about your use case?

@witty-belgium-75866 as @millions-furniture-75402 points out ESC allows you to compose multiple config files, override and inherit values, etc: https://www.pulumi.com/docs/esc/get-started/import-environments/
