Feature | Add a Tag to Resources Indicating the Layer

[exequielrafaela]

Describe the Feature

• The feature request is to add a tag to the resources that indicates the layer for example here https://github.com/binbashar/le-tf-infra-aws/blob/d12db58487f578b88c0aa0197289c6b1a19acbc6/network/us-east-1/base-network/locals.tf#LL2C4-L2C4. Consider this must be a project wide implementation covering, ideally, all the layers of the Ref Arch.
• This could help track the code that created the implementation. If the layer has well-documented code (self-documented, a readme, or a link to Confluence), it would eliminate the need to rely on someone remembering it.

Expected Behavior

Once implemented, each resource should have a tag indicating the layer. This should aid in tracking the code that created the implementation.

Use Case

This feature is valuable for improving code traceability and documentation. It will provide a direct link between resources and the layer that created them, making it easier to understand and manage the codebase.

Describe Ideal Solution

The ideal solution would involve adding a tag to each resource during its creation, indicating the layer. The tag should be easily visible and accessible for reference. Consideration should be given to whether the tag can be obtained through a function or similar method to avoid the hardcoded example below.

locals {
  tags = {
    Terraform   = "true"
    Environment = var.environment
    Layer = "base-dns/binbash.co"
  }
}

Alternatives Considered

An alternative could be to continue without these tags, relying on developers to remember or find the relevant layer for each resource. However, this could lead to inefficiencies and potential errors.

Additional Context

This feature request arose from a discussion about improving code traceability and documentation. The addition of a layer tag to each resource was suggested as a potential solution.
