When specifying a general region by country and area the blueprint may not map to a specific datacenter resulting in a failure to preview or apply the Environment.

Overview

The specified blueprint properties for region do not map to an underlying datacenter resulting in failure details for either AWS or Azure:

Apply region in aws :: end :: failure
  error in location.folder.example
  No aws region found matching the specified criteria: {'area': 'northeast', 'city': 'Virginia', 'country': 'USA', 'name': 'my-region'}
  Remove conflicting criteria.

Apply region azure in azure :: end :: failure
  error in location.folder.example
  No azure region found matching the specified criteria: {'area': 'northeast', 'city': 'Virginia', 'country': 'USA', 'name': 'my-region', 'created': '2020-09-04T17:33:55.509370Z'}
  Remove conflicting criteria.

Resolution

The current recommended method for region selection is using region specific definitions for AWS and Azure outlined in each cloud providers regions specifications.

location:
  region:
    portable-specific-region:
      aws: us-west-2
      azure: westus2
