  • Adds Renovate configuration (along with documentation)
  • Adds terraform-docs along with corresponding tools
  • Adds example of using TF workspaces

Also let's come up with the new name for this template repo, and I'll adjust accordingly in the other dependent repos.

23-31: Version skew with OpenTofu binary remains unresolved
[email protected] is still one minor ahead of the opentofu runtime pinned in aqua.yaml (v1.9.x). The mismatch can surface parsing errors on newer HCL constructs. Align both to the same minor stream (either bump the runtime or pin the linter down).

1-5: Consolidate to a single H1 heading

The file still has three top-level headings, which violates MD025 and makes anchor links unpredictable. Keep only the canonical repository name as # … and demote the alternates.

-# infra-monorepo-template
-
-# iac-monorepo-template

aqua.yaml (1)

13-15: Add a Renovate hint for the new terraform-docs package

Every other pinned dependency in this file carries a # renovate: comment so Renovate can bump versions automatically. Replicating that for terraform-docs keeps the file consistent and prevents manual updates.

   - name: terraform-docs/[email protected]
+    # renovate: depName=terraform-docs/terraform-docs
root-modules/template-root-module/variables.tf (1)

11-15: Add basic validation for prefix
An empty string (or all-whitespace) silently passes today and will later surface in resource names. A minimal validation guard is cheap insurance.

 variable "prefix" {
   description = "The prefix to prepend to the generated name"
   type        = string
   default     = "random"
+  validation {
+    condition     = length(trimspace(var.prefix)) > 0
+    error_message = "prefix must be a non-empty string."
+  }
 }
.github/renovate.json5 (1)

12-15: Trailing comma may confuse non-JSON5 parsers
While JSON5 tolerates trailing commas, some downstream tooling (e.g., GitHub’s code owners viewer or UI linters) still parses files with a strict JSON engine. If you hit parsing errors, just drop the comma after "components/**".

root-modules/template-root-module/README.md (1)

5-16: Clarify CLI examples & keep them tool-agnostic

The docs jump straight to tofu workspace … while many users will still invoke terraform.
To avoid copy-paste errors, consider presenting both commands or a short note such as “replace tofu with terraform if you’re not using OpenTofu”.

-# Set up a new workspace for `dev` -- only needs to be done once
-tofu workspace new dev
-# Select the workspace, this is how TF knows where the state file is stored
-tofu workspace select dev
-# Apply the configuration with the corresponding tfvars file
-tofu apply --var-file tfvars/dev.tfvars
+# Set up a new workspace for `dev` (run once)
+terraform workspace new dev   # or: tofu workspace new dev
+# Select the workspace so TF knows where the state file is stored
+terraform workspace select dev
+# Apply the configuration with the corresponding tfvars file
+terraform apply -var-file=tfvars/dev.tfvars

Minor, but improves portability and avoids support questions.

root-modules/template-root-module/tfvars/dev.tfvars (1)

1-1: Environment-specific tfvars looks fine, but consider committing only “*.tfvars.example” templates

Committing concrete values (even benign ones) makes cloning users think these are canonical. A common pattern is to version dev.tfvars.example/prod.tfvars.example with placeholder values and let pipelines or local copies provide the real files (often ignored via .gitignore). This avoids accidental drift between repo defaults and live deployments.

If you keep the concrete files under VCS, document clearly in the README how they’re used with workspaces (terraform workspace select dev && terraform apply -var-file=tfvars/dev.tfvars, etc.) so newcomers don’t mis-apply the wrong environment.

root-modules/template-root-module/tfvars/prod.tfvars (1)

1-1: Same remark as for dev.tfvars—consider shipping this as a .example or documenting its usage

Nothing technically wrong here; just repeating the suggestion to avoid committing live environment defaults unless that’s intentional.

.terraform-docs.yaml (1)

1-19: Configuration looks correct — good job integrating terraform-docs

The YAML is well-formed, options match the v0.20.x schema, and the inject template markers align with the pre-commit hook convention.
No action needed.

root-modules/template-root-module/outputs.tf (1)

1-4: Confirm that the sub-module actually exports random_pet_name

This output forwards module.random_pet.random_pet_name. Compilation will fail if the child module lacks a matching output "random_pet_name" block.

Please verify (or add) the output in modules/random_pet:

output "random_pet_name" {
  value = random_pet.this.id
}
root-modules/template-root-module/versions.tf (1)

2-8: LGTM – version bumps look sensible
No breaking-change flags detected for Terraform 1.10.x or random 3.7.x.

root-modules/template-root-module/main.tf (1)

11-13: Verify local module path correctness
The relative path ../../child-modules/random-pet assumes this root module is invoked from root-modules/template-root-module. Double-check that consumers (e.g., Terraform Cloud workspaces or CI pipelines) execute terraform from the expected directory; otherwise the path will break.

Poem

🐇
In burrows deep, configs bloom anew,
Renovate wakes before the dew.
Docs are clearer, modules grow,
Prefixes and pets in tidy rows.
Linters fresh, tfvars in tow—
This rabbit hops where changes flow!

Also let's come up with the new name for this template repo

If I'm not mistaken, we're referencing this repo in the audit docs and possibly elsewhere. @oycyc did you if we need to update the link/name?

Ah this is good point. I just checked, looks like in GDrive, the only place it's been mentioned is in a previous audit reports, but not our audit boilerplate template. Also all good on Notion as well. (redacted screenshot since this is a public repo)
