I have a multiple region project in AWS - but Pulumi seems to only take one region via config. Does this mean I need a different stack for each region? So dev.us-east-1, dev.us-west-1, prod.us-east-1, etc etc ?

you can either set it on the stack:

pulumi config set aws:region us-west-2

or you can create providers which you pass to resources: https://www.pulumi.com/docs/reference/pkg/aws/provider/#region_python

OK, thanks! i couldn’t find any examples that dealt with this so I didn’t know

@happy-window-22449 example here: https://github.com/pulumi/pulumi-aws/blob/master/examples/multiple-regions/index.ts

ah perfect, i’m using Python but I should be able to do the same there

Here's a very basic python example.

import pulumi
import pulumi_aws as aws

regs = aws.get_regions()

for i in regs.names:
    new_provider = aws.Provider(f'provider-{i}',
        region=i
    )

    vpc = aws.ec2.DefaultVpc(f'default-vpc-{i}',
        opts=pulumi.ResourceOptions(provider=new_provider)
    )
