Is there a way to create terraform aws_s3_bucket resources dynamically in different regions? Argument region is no longer supported, creating provider aliases in different regions dynamically is also not supported. Is there a way to do this?
Yes - you can use Provider Aliasing and regions are reported as supported per the AWS provider documentation
I suggest keeping your terraform cleanly modularized when using aliasing to keep the copy/paste code per region to a minimum
