You can do something like the following:
Copy code
"""An AWS Python Pulumi program"""
import pulumi
import pulumi_aws as aws
# Create an AWS resource (S3 Bucket)
awsConfig = pulumi.Config("aws")
awsRegion = awsConfig.get("region")
if awsRegion != "us-east-2":
raise ValueError("provider has bad region")
pulumi.export("aws_region_selected", awsRegion)pulumi config set aws:region us-east-1pulumi config set aws:region us-east-2g

08/03/2021, 3:20 PMOh wait… the default provider. I’m not sure you can get the default provider (but it uses the default region declared in your config so what @cool-fireman-90027 wrote will get you the same information). If you need to do something with the provider you should explicitly declare a provider resource in your code.
But as far as your question about how to validate outputs, the code I wrote should be applicable for all outputs.

08/03/2021, 5:02 PMokay thank you, it seems it's also limited to apply scope again 😞
about default provider - since the best practice is to declare your provider directly, would be better to disable default providers entirely? I noticed in some threads here people having problems when migrating away from default provider to declared one
