Migration to v1.0.0

New Features

With v1.0.0 we have tried to follow a more consistent pattern in module design.

  • Use of the context provided by the terraform-null-label module.
  • Ability to process hosted zones from other modules easier.

Breaking changes in v1.0.0

Releases prior to v1.0.0 of this module attempted to maintain compatibility, so required no code changes were needed. With v1.0.0 in order to address reported issues changes to the code were necessary that did not allow for upgrade without code changes. If you are unable to afford a break in functionality during upgrade lock version to an earlier compatible version.

Behavior changes

  • Previously, the aws_route53_key_signing_key and random_string resources used an index based on the hosted zone ID as passed in by the zone_ids variable. This caused an issue where the values were not known until apply affecting plan execution.

  • Previously, the aws_kms_key and ams_key_alias resources were handled internally. These are now handled with an external module which will destroy the old resources upon apply.

  • Previously, prior to Terraform 1.0 provider blocks were necessary inside external modules when requiring change from root module values. This causes issues when executing with newer versions.

Input Variable Changes

  • zone_ids removed. Use zones instead.

  • zones added. Internal changes required a new format for input of zones to assign the KSK to.

  • deletion_window_in_days added. To change the deletion window on key from the previous hard-coded default of 7 days.

Output Variable Changes

  • this_key_arn deprecated. Use key_arn instead.

  • key_arm added. Supplies the KMS key ARN setup for Route53 hosted zone KSK.
