I was able to get this from the parent urn inside my provider's

construct

method, but not without being hacky and accessing a private/internal method. Still would like to figure out a better way to do this.

async construct(
    name: string,
    type: string,
    inputs: pulumi.Inputs,
    options: pulumi.ComponentResourceOptions
  ): Promise<provider.ConstructResult> {
    const [, , stack, , program] = (
      await (<any>options.parent?.urn)["promise"]()
    ).split(":");

    // more code
  }

I see the issue now - the class responsible for the auto-naming was instantiated in module scope, so the project and stack name were initialized when the framework is imported. That works fine when running in the nodejs language runtime because

runtime.settings.LocalStore

sets stack/project using env var values as I mentioned above. If not set they default to literal strings

project

and

stack

. When running in context of a provider, the `Server`'s

construct

method configures the runtime based on the values in the

ConstructRequest

. tl;dr - instead of calling

getProject()

and

getStack()

to set the

name

value in my class from its constructor, I made

name

a getter and now it works as expected
