21-26: LGTM! Helper variables are properly implemented.

The test fixture appropriately implements the new helper variables with mock values, providing good examples for module usage.


22-26: Verify consistency across test fixtures.

Let's ensure these helper variables are consistently implemented across all test fixtures.

✅ Verification successful

Helper variables are consistently implemented across test fixtures

The verification shows that both test fixtures (tests/fixtures/default/regional/main.tf and tests/fixtures/default/regional/istio-csr/main.tf) consistently implement all five helper variables:

  • helpers_cost_center
  • helpers_data_classification
  • helpers_email
  • helpers_repository
  • helpers_team

21-22: LGTM: Variable alignment improved.

The formatting changes to artifact_registry and cluster_prefix improve readability by maintaining consistent alignment.


23-27: Verify helper variables configuration.

The new helper variables appear to be part of the terraform-core-helpers module integration. These variables typically help with resource tagging and organization.

Let's verify the helper variables are properly defined:

✅ Verification successful

Based on the results and the learnings from previous interactions, I can now provide a final response:

Helper variables are properly configured and validated in child module

The helper variables are correctly defined in both the test fixture (tests/fixtures/default/regional/istio-csr/variables.tf) and the source module (regional/istio-csr/variables.tf). According to the learnings, these variables are validated in the terraform-core-helpers child module, so they don't need additional validation in the parent module.

4-22: Add descriptions and validation rules for the helper variables.

While the variable declarations are syntactically correct, they would benefit from additional documentation and validation:

  1. Add descriptions to clarify the expected values and purpose of each variable
  2. Consider adding validation rules, especially for:
    • helpers_email: Email format validation
    • helpers_data_classification: Allowed classification levels
    • helpers_repository: Repository name format

Here's an example of how to enhance these declarations:

 variable "helpers_cost_center" {
   type = string
+  description = "Cost center identifier for resource tracking"
 }

 variable "helpers_data_classification" {
   type = string
+  description = "Data classification level for the resource"
+  validation {
+    condition     = contains(["public", "internal", "confidential", "restricted"], var.helpers_data_classification)
+    error_message = "Data classification must be one of: public, internal, confidential, restricted"
+  }
 }

 variable "helpers_email" {
   type = string
+  description = "Contact email address for the resource owner"
+  validation {
+    condition     = can(regex("^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,}$", var.helpers_email))
+    error_message = "Invalid email format"
+  }
 }
tests/default.tftest.hcl (1)

28-34: LGTM! Consider adding documentation for the helper variables.

The variables block is well-structured and aligns with the integration of the terraform-core-helpers module.

Consider adding a comment block above the variables section explaining the purpose of these helper variables and their relationship to the terraform-core-helpers module:

+# Helper variables for resource tagging and metadata management
+# These mock values are used to test the terraform-core-helpers module integration
 variables {
   helpers_cost_center         = "mock-cost-center"
   helpers_data_classification = "mock-data-classification"
   helpers_email               = "mock-team@osinfra.io"
   helpers_repository          = "mock-owner/mock-repository"
   helpers_team                = "mock-team"
 }

4-5: Consider using a more reliable module source.

While GitHub sources work, they're not recommended for production use as they:

  • Depend on GitHub availability
  • May have rate limiting issues
  • Don't support checksums verification

Consider publishing this module to the Terraform Registry or using a private registry for better reliability and security.

66-67: Fix alignment inconsistency in module arguments

There's an inconsistent spacing in the alignment of the = signs:

  • artifact_registry has 11 spaces
  • cluster_prefix has 14 spaces

Apply this diff to maintain consistent alignment:

-  artifact_registry           = "mock-docker.pkg.dev/mock-project/mock-virtual"
-  cluster_prefix              = "mock-cluster"
+  artifact_registry          = "mock-docker.pkg.dev/mock-project/mock-virtual"
+  cluster_prefix            = "mock-cluster"
regional/variables.tf (1)

52-75: Enhance variable descriptions with examples.

Consider adding examples to the descriptions to make it clearer for users:

 variable "helpers_cost_center" {
-  description = "The cost center the resources will be billed to, must start with 'x' followed by three or four digits"
+  description = "The cost center the resources will be billed to, must start with 'x' followed by three or four digits (e.g., x123 or x1234)"
   type        = string
 }

 variable "helpers_data_classification" {
-  description = "The data classification of the resources can be public, internal, or confidential"
+  description = "The data classification of the resources: must be one of 'public', 'internal', or 'confidential'"
   type        = string
 }

 variable "helpers_repository" {
-  description = "The repository name (should be in the format 'owner/repo' containing only lowercase alphanumeric characters or hyphens)"
+  description = "The repository name in the format 'owner/repo' containing only lowercase alphanumeric characters or hyphens (e.g., 'osinfra-io/terraform-core-helpers')"
   type        = string
 }

 variable "helpers_team" {
-  description = "The team name (should contain only lowercase alphanumeric characters and hyphens)"
+  description = "The team name containing only lowercase alphanumeric characters and hyphens (e.g., 'platform-team')"
   type        = string
 }

4-22: Verify if these variables should be required.

All variables are currently required as they lack default values. Consider whether some variables could be optional with sensible defaults.

Let's check how these variables are used in the helper module:

✅ Verification successful

Let me gather more information about how these variables are used.


These helper variables should remain required

Based on the evidence found:

  1. These variables are used to provide essential metadata for resource management:

    • helpers_cost_center: Required for billing attribution
    • helpers_data_classification: Required for security compliance
    • helpers_email: Required for team ownership
    • helpers_repository: Required for source tracking
    • helpers_team: Required for team ownership
  2. The variables have strict format requirements (e.g., cost center must start with 'x' followed by digits, repository must follow 'owner/repo' format), making default values potentially dangerous.

  3. These variables are consistently used in both the main module and istio-csr submodule through the core-helpers module, indicating they are fundamental to the infrastructure's organization and compliance requirements.

5-5: LGTM! Verify references to cluster_id.

The migration from local variables to module.helpers for zone, region, and env looks good. The conditional logic for zone-based formatting is preserved correctly.

Let's verify that all references to local.cluster_id have been updated to handle the new structure:

✅ Verification successful

All references to cluster_id are properly aligned

The verification shows that cluster_id is only used within the same file:

  1. Line where it's defined as a local variable using module.helpers
  2. Line where it's used in helm_values map, correctly referenced as local.cluster_id
🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Search for any references to cluster_id to ensure compatibility
rg "cluster_id" --type tf

Length of output: 361


9-9: LGTM! Verify Datadog environment mapping.

The update to use module.helpers.environment for Datadog pod labels is correct and maintains the proper label format.

Let's verify the environment values align across the configuration:

✅ Verification successful

✓ Environment configuration is consistent across Datadog labels

The verification shows that module.helpers.environment is used consistently for Datadog environment labels in both the main cert-manager configuration (regional/locals.tf) and the istio-csr component (regional/istio-csr/locals.tf). The environment mapping is properly aligned across configurations.

🏁 Scripts executed

.gitignore (1)

33-35: LGTM! Verify external modules handling.

The addition of .external_modules to ignore Checkov's external module cache is appropriate and follows the file's established structure.

Let's verify how this integrates with the terraform-core-helpers module:

✅ Verification successful

.external_modules ignore entry is correctly configured

The .gitignore entry is properly set up to support Checkov's external module scanning:

  • Confirmed Checkov is configured in pre-commit with --download-external-modules=true
  • The repository contains multiple Terraform files that will be scanned
  • .external_modules directory (temporary cache) will be correctly ignored
🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify the module integration and Checkov configuration

# Test 1: Check if there are any Checkov-specific configurations in the repository

Length of output: 1532

regional/main.tf (2)

7-11: LGTM! Module configuration looks good.

The variable mapping is consistent and well-structured.


5-5: Verify the module version stability.

The module is pinned to v0.1.0 which suggests it's in early development:

  • Early versions may have breaking changes
  • The API might not be stable
  • Documentation might be incomplete

Please verify:

  1. The module's stability and production readiness
  2. Whether a more flexible version constraint (e.g., ~> 0.1.0) would be appropriate
.pre-commit-config.yaml (3)

32-32: LGTM on version update.

Good practice keeping the Checkov security scanner updated to the latest patch version.


37-37: Verify performance impact of downloading external modules.

While enabling --download-external-modules is necessary for scanning the new terraform-core-helpers module, be aware that this could:

  1. Increase the pre-commit hook execution time
  2. Require internet connectivity for all pre-commit runs
  3. Potentially introduce security risks by downloading external code during checks

Consider caching the external modules locally if the increased execution time becomes an issue.


38-39: Verify the rationale for skipping CKV_TF_1.

The CKV_TF_1 check ensures all Terraform resources have proper tags/labels. Please confirm:

  1. Is tag management being handled by the new terraform-core-helpers module?
  2. If yes, can you add a comment explaining why this check is being skipped?
  3. If no, consider keeping this check enabled to ensure proper resource tagging.

Run this script to check if the helpers module handles tagging:

tests/fixtures/default/regional/main.tf (2)

66-71: Maintain consistent alignment for module arguments.

The alignment of the new helper variables is consistent, which improves readability.


66-71: Verify helper variables are consistently implemented across all test fixtures.

The addition of helper variables aligns with the PR objective of using the terraform-core-helpers child module. However, since this is a test fixture, we should ensure consistency across all test cases.

✅ Verification successful

Helper variables are properly implemented and tested across fixtures

The verification shows:

  • All helper variables are correctly declared in variables.tf with proper string type definitions
  • The variables are consistently used in the module block in main.tf
  • Mock values are properly defined in default.tftest.hcl with appropriate test data:
    • Cost center: "mock-cost-center"
    • Data classification: "mock-data-classification"
    • Email: "mock-team@osinfra.io"
    • Repository: "mock-owner/mock-repository"

68-72: 💡 Codebase verification

Helper variables need type constraints and descriptions

While the helper variables are defined, they lack proper documentation and type constraints. Each variable should have:

  • A description explaining its purpose and expected values
  • Appropriate type constraints (e.g., validation rules, allowed patterns)

Locations needing attention:

  • tests/fixtures/default/regional/istio-csr/variables.tf:
    • helpers_cost_center: Add description and validation rules
    • helpers_data_classification: Add description and allowed values
    • helpers_email: Add description and email format validation
    • helpers_repository: Add description and URL format validation
    • helpers_team: Add description and naming convention rules

27-35: ⚠️ Potential issue

Add validation blocks to enforce variable constraints.

The descriptions specify format requirements, but there are no validation rules to enforce them.

Add validation blocks to ensure data integrity:

 variable "helpers_cost_center" {
   description = "The cost center the resources will be billed to, must start with 'x' followed by three or four digits"
   type        = string
+  validation {
+    condition     = can(regex("^x\\d{3,4}$", var.helpers_cost_center))
+    error_message = "Cost center must start with 'x' followed by exactly three or four digits."
+  }
 }

 variable "helpers_data_classification" {
   description = "The data classification of the resources can be public, internal, or confidential"
   type        = string
+  validation {
+    condition     = contains(["public", "internal", "confidential"], var.helpers_data_classification)
+    error_message = "Data classification must be one of: public, internal, confidential."

1-3: Verify integration with existing resources.

The helpers module is added but its outputs don't appear to be used in the existing resources. Please clarify:

  1. How are the helper module's outputs being utilized?
  2. Should any of the existing resources be tagged or labeled using the helper values?
#!/bin/bash
# Description: Check if helper values are used in other Terraform files
# Look for potential uses of helper module outputs
rg -l "module.helpers" --type tf

# Check for any label or tag blocks that might benefit from helper values
ast-grep --pattern 'tags = {

4-12: Consider using a more stable version of terraform-core-helpers.

The module is currently pinned to v0.1.0 which is an early version. This could be unstable or missing important features/fixes.

Let's check if there are newer versions available:

Additionally, consider:

  1. Using your organization's private module registry instead of direct GitHub URLs for better security and control
  2. Adding variable validation blocks to ensure proper input values

Line range hint 1-4: LGTM: Good cleanup of local variables

The removal of env, environment, and env_map local variables helps reduce duplication by centralizing environment-related logic in the helpers module.


12-12: Verify helpers module configuration

The change from local variable to module.helpers.environment requires proper configuration of the helpers module.

Let's verify the module configuration and usage:

✅ Verification successful

Helpers module is properly configured and used

The helpers module is correctly configured in both regional/main.tf and regional/istio-csr/main.tf using the same source version (v0.1.0). The module is properly referenced in the code changes, and the usage of module.helpers.environment is consistent across the files where it's used.

The version update from 2.16.0 to 2.16.1 is documented correctly. As noted in the header comment, this is informational only since child modules inherit provider configurations from the parent.


19-21: Verify the helpers module version.

While adding the terraform-core-helpers module aligns with the PR objectives, using v0.1.0 might expose us to breaking changes in early releases.

Let's check if there's a more recent stable version:

✅ Verification successful

Version v0.1.0 is currently the latest release

The terraform-core-helpers module is using v0.1.0, which is confirmed to be the latest release as of October 26, 2024. While early versions can be risky, using the latest available release is appropriate in this case.

🛠️ Refactor suggestion

Consider adding variable validation for helper values.

While the mock values are appropriate for testing, consider adding variable validation blocks in the actual module to ensure these helper values meet your organization's standards (e.g., specific email formats, repository naming conventions).

Example validation block to add in the main module:

variable "helpers_email" {
  description = "Contact email for the resource owner"
  type        = string
  
  validation {
    condition     = can(regex("^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,}$", var.helpers_email))
    error_message = "The helpers_email value must be a valid email address."
  }
}

⚠️ Potential issue

Add email format validation.

The email variable should validate the input format.

Add a validation block:

 variable "helpers_email" {
   description = "The email address of the team responsible for the resources"
   type        = string
+  validation {
+    condition     = can(regex("^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,}$", var.helpers_email))

💡 Codebase verification

Missing validation rules for helper variables

The variables are defined in multiple variables.tf files but none of them implement the validation rules specified in the README. The variables are declared only with type definitions, missing crucial validation blocks to enforce:

  • helpers_cost_center: pattern validation for 'x' followed by 3-4 digits
  • helpers_data_classification: allowed values validation for public/internal/confidential
  • helpers_repository: format validation for owner/repo pattern and character restrictions
  • helpers_team: character set validation for lowercase alphanumeric and hyphens
🔗 Analysis chain

Verify validation rules implementation.

The new helper variables have clear descriptions with specific validation rules. Let's verify that these rules are properly implemented in the variables.tf file.
