ECR : Add support for archive storage class

[lbertorello]

Description

Hi,
Amazon ECR now offers a new archive storage class to reduce storage costs for large volumes of rarely accessed container images. The new archive storage class helps you meet your compliance and retention requirements while optimizing storage cost. As part of this launch, ECR lifecycle policies now support archiving images based on last pull time, allowing you to use lifecycle rules to automatically archive images based on usage patterns.

Affected Resource(s) or Data Source(s)

• data : aws_ecr_lifecycle_policy

Potential Terraform Configuration

data "aws_ecr_lifecycle_policy_document" "ecr_lifecycle_policy" {
  rule {
    priority    = 1
    description = "Archive unused images after 90 days"

    selection {
      tag_status   = "any"
      count_type   = "sinceImagePulled"
      count_unit   = "days"
      count_number = 90
    }

    action {
      type                 = "transition"
      target_storage_class = "archive"
    }
  }

  rule {
    priority    = 2
    description = "Delete archive images after 90 days"

    selection {
      tag_status    = "any"
      count_type    = "sinceImageTransitioned"
      count_unit    = "days"
      storage_class = "archive"
      count_number  = 90
    }

    action {
      type = "expire"
    }
  }
}
