To pass the output of a get_x pulumi call to another pulumi resource needs the following: async def get_my_info(params): result = pulumi_aws.ec2.get_something() return result.id # in your user code a_thing = pulumi_aws.ec2.SomeResource(params, input_id = get_my_info()) The get_my_info function will get called as part of the setup for the SomeResource invocation by the provider at run time.
