}

Expected Behavior

I expect to the the ID for the subnet in the VPC I am currently working with.

Actual Behavior

I get back the ID for the subnet that is in a DIFFERENT VPC. That is because the data resource does not allow me to specify which VPC I want this data from. It seems to pick a VPC at random or the last one created.

Steps to Reproduce

1. This assume that you are attempting to use the provider against an existing VPC. But to get started. Create two different VPCs in the same region using the Console UI. Use the default provided by the console to generate the subnet names.
2. Configure your Terraform template for your region and provider
3. Insert the code snippet above
4. Run terraform apply
5. You should get the subnet id back, but that subnet id is for which one of the two VPCs? 50/50 it is the one you expected or needed.
