regional/locals.tf (2)
4-12: Add documentation for local variablesWhile the code is relatively self-explanatory, adding inline documentation for the
envandenv_mapvariables would improve maintainability and help other developers understand their purpose and usage.Consider adding comments like this:
locals { # Maps the full environment name to its shorthand version # Falls back to the Terraform workspace name if the environment is not defined env = can(local.env_map[var.environment]) ? local.env_map[var.environment] : terraform.workspace # Mapping of full environment names to their shorthand versions env_map = { "non-production" = "nonprod" "production" = "prod" "sandbox" = "sb" } }
7-11: Review naming convention for environment shorthandsThe current naming convention for environment shorthands is not entirely consistent. While "nonprod" and "prod" follow a similar pattern, "sb" for sandbox breaks this pattern.
Consider standardizing the naming convention. For example:
env_map = { "non-production" = "np" "production" = "pd" "sandbox" = "sb" }This makes the shorthand names more consistent in length and style. Alternatively, if "nonprod" and "prod" are preferred, consider using "sand" for sandbox to maintain consistency:
env_map = { "non-production" = "nonprod" "production" = "prod" "sandbox" = "sand" }Choose the convention that best fits your team's preferences and existing naming standards.
.github/workflows/test.yml (2)
15-18: LGTM: Well-structured job definition using external workflow.Using an external workflow from
osinfra-io/github-terraform-gcp-called-workflowshelps maintain consistency across projects. Pinning the version tov0.2.5is a good practice for stability.Consider making the job name more specific, e.g., "Terraform-Tests" or "GCP-Terraform-Tests", to better reflect its purpose.
19-23: Review job conditions and inputs for security and maintainability.Good:
- Excluding Dependabot from running tests is appropriate.
- Using a GitHub variable for the Terraform version enhances maintainability.
Suggestions for improvement:
Consider using GitHub secrets or variables for sensitive information:
- The service account email
- The workload identity provider
The workload identity provider string is quite long. Consider breaking it into smaller parts or storing it as a secret/variable for better readability and maintainability.
Here's a suggested refactor:
with: service_account: ${{ secrets.GCP_SERVICE_ACCOUNT }} terraform_version: ${{ vars.TERRAFORM_VERSION }} workload_identity_provider: ${{ secrets.GCP_WORKLOAD_IDENTITY_PROVIDER }}This change would require setting up the corresponding secrets and variables in your GitHub repository settings.
tests/default.tftest.hcl (4)
1-10: LGTM! Consider adding a brief description of the test file's purpose.The comments and mock provider definitions look good. The inclusion of documentation links is helpful. As a minor enhancement, consider adding a brief description of this test file's specific purpose at the beginning.
12-22: LGTM! Consider adding assertions and more variables for comprehensive testing.The "default_regional" test run is well-structured. To enhance its effectiveness:
- Consider adding assertions to validate the expected outcomes of the apply command.
- You might want to include more variables to test different scenarios or configurations.
Example of adding an assertion:
assert { condition = output.some_output == expected_value error_message = "The output does not match the expected value" }
32-34: LGTM! Consider expanding global variables and clarifying their usage.The global
environmentvariable is a good start. To enhance this:
- Consider adding more global variables that might be relevant across multiple test runs.
- It would be helpful to add a comment explaining how these global variables are used in the test runs.
- Ensure that the
environmentvariable is actually used in the test runs. If not, consider adding it to the test runs or remove it if unnecessary.Example of expanded global variables:
variables { environment = "mock-environment" project_id = "mock-project-id" # Add more relevant global variables }
1-34: Overall, good foundation for Terraform testing. Consider these enhancements for robustness.This Terraform test configuration file provides a solid starting point for testing your Terraform modules. To further improve its effectiveness and maintainability:
- Add more comprehensive assertions in both test runs to validate expected outcomes.
- Ensure consistent use of variables across test runs, or document why they differ.
- Expand the use of global variables and clarify their purpose in the tests.
- Add comments to explain the specific purpose of each test run and how they differ.
- Consider adding more test runs to cover additional scenarios or edge cases.
These enhancements will make your tests more robust, easier to understand, and maintain in the long run.
.pre-commit-config.yaml (2)
13-15: Consider updating pre-commit-terraform to the latest version.The current version (v1.96.1) is relatively recent, but not the latest available. Consider updating to the most recent version to ensure you have the latest features and bug fixes.
31-33: Consider updating checkov to the latest version.The current version (3.2.257) is relatively recent, but not the latest available. Consider updating to the most recent version to ensure you have the latest security checks and features.
tests/fixtures/default/regional/manifests/main.tf (1)
36-43: Kubernetes provider configuration looks goodThe Kubernetes provider is correctly configured and consistent with the Helm provider setup. The use of "https://" prefix for the host is appropriate.
For consistency with the Helm provider and to reduce duplication, consider using the same local value approach suggested earlier:
locals { kubernetes_config = { cluster_ca_certificate = base64decode(local.regional.cluster_ca_certificate) host = "https://${local.regional.cluster_endpoint}" token = data.google_client_config.current.access_token } } provider "kubernetes" { cluster_ca_certificate = local.kubernetes_config.cluster_ca_certificate host = local.kubernetes_config.host token = local.kubernetes_config.token }This approach will make the configuration more maintainable and easier to update in the future.
tests/fixtures/default/regional/main.tf (4)
1-16: Consider adding version constraints for providersWhile the provider declarations are correct, it's a best practice to specify version constraints for each provider. This ensures reproducibility and prevents unexpected behavior due to provider updates.
Consider adding version constraints like this:
terraform { required_providers { google = { source = "hashicorp/google" version = "~> 4.0" # Replace with the desired version } helm = { source = "hashicorp/helm" version = "~> 2.0" # Replace with the desired version } kubernetes = { source = "hashicorp/kubernetes" version = "~> 2.0" # Replace with the desired version } } }
18-31: Helm provider configuration looks goodThe Helm provider configuration is correct and follows best practices. It properly uses the Kubernetes authentication mechanism and Google client config for access.
Consider adding a comment explaining the source of
local.regionalfor better code readability, like this:# local.regional is defined in a locals block, likely in another file provider "helm" { # ... rest of the configuration }
51-61: Remote state configuration looks good, consider adding error handlingThe remote state data source is correctly configured to use a GCS backend, which is a best practice for managing Terraform state in a team environment.
Consider adding error handling for cases where the remote state might not exist:
data "terraform_remote_state" "regional" { backend = "gcs" workspace = "mock-workspace" config = { bucket = "mock-bucket" } lifecycle { postcondition { condition = self.workspace == "mock-workspace" error_message = "Failed to load remote state. Ensure the workspace exists and you have the necessary permissions." } } }This will provide a more informative error if the remote state cannot be loaded.
63-69: Module declaration is correct, consider adding documentationThe module declaration is properly structured and uses variables for flexibility, which is a good practice.
Consider adding a comment block above the module declaration to explain its purpose and the significance of the "test" module. This will improve code readability and maintainability. For example:
# This module sets up the test environment for the regional configuration. # It uses mock values for artifact registry and pulls in environment and region variables. module "test" { # ... rest of the module configuration }regional/variables.tf (2)
64-73: Update environment variable description to include all allowed values.The
environmentvariable has a validation block that includes "mock-environment" as an allowed value, but this is not mentioned in the variable description.Consider updating the description to include all allowed values:
variable "environment" { description = "The environment must be one of `mock-environment`, `sandbox`, `non-production`, `production`" type = string default = "sandbox" validation { condition = contains(["mock-environment", "sandbox", "non-production", "production"], var.environment) error_message = "The environment must be one of `mock-environment` for tests or `sandbox`, `non-production`, or `production`." } }This ensures that the description accurately reflects all allowed values.
1-96: Overall, the variables.tf file is well-structured but could benefit from some enhancements.The file provides a comprehensive set of variables for configuring a Gatekeeper deployment. Here are some overarching suggestions for improvement:
- Input Validation: Add validation blocks to all variables where possible to ensure valid input and prevent configuration errors.
- Environment-Specific Defaults: Consider using locals to define environment-specific default values for variables like
replicasandartifact_registry.- Version Management: Implement a strategy for keeping the
gatekeeper_versionup-to-date, possibly using external data sources.- Documentation: Ensure all variable descriptions accurately reflect their purpose and constraints, including all allowed values for enumerated types.
These enhancements will improve the robustness and maintainability of your Terraform configuration.
regional/README.md (2)
1-8: Consider clarifying the requirements sectionThe "No requirements" statement in the Requirements section might be misleading. Although the module inherits provider configurations from its parent, it still relies on specific provider versions (Helm 2.16.0 and Kubernetes 2.33.0) as mentioned in the Providers section. Consider adding these version requirements to the Requirements section for clarity.
31-49: Inputs section is comprehensive, with minor suggestions for improvementThe Inputs section is well-documented, providing clear descriptions, types, and default values for each variable. This is excellent for module usability. A few suggestions for improvement:
Consider adding a brief explanation or comment for the specific default value of
artifact_registry. This might be environment-specific and could benefit from additional context.For the
environmentinput, consider using a validation block in the Terraform code to ensure only allowed values (sandbox,non-production,production) are used.For CPU and memory related inputs, consider adding a comment about how these values were determined and when they might need adjustment.
These minor enhancements could further improve the module's documentation and usability.

tests/fixtures/default/regional/variables.tf (1)
1-10: LGTM! The variable definitions align with your preferred style.The minimal variable definitions for
environmentandregionare consistent with your preference for concise Terraform configurations. This approach maintains simplicity while still providing the necessary flexibility for different deployment scenarios.While the current implementation is acceptable, consider the following optional suggestions that maintain minimalism:
You might want to add a brief comment above each variable to indicate its purpose, which can be helpful for other team members without adding verbosity to the variable blocks themselves.
If there are specific valid values for these variables, you could add a
validationblock to ensure correct input without adding unnecessary complexity.Let me know if you'd like me to provide examples of these optional improvements.
.github/workflows/dependabot.yml (4)
5-6: Verify if the current permissions are sufficient.The
contents: readpermission follows the principle of least privilege, which is good. However, for approving and merging pull requests, additional permissions might be needed.Please check if the following permissions are required for this workflow:
pull-requests: write(for approving pull requests)contents: write(for merging pull requests)You can add these permissions if needed:
permissions: contents: write pull-requests: writeAlternatively, if these permissions are granted through the
PR_APPROVE_AND_MERGE_PAT, ensure that the token has the minimum required permissions.
1-3: Workflow name and trigger look good, but be cautious withpull_request_target.The workflow name accurately describes its purpose, and using
pull_request_targetis appropriate for Dependabot workflows. However, be aware thatpull_request_targetcan be a security risk if not used carefully, as it runs with the permissions of the base repository.To ensure the workflow is secure, please verify that:
- The external workflow being used (
osinfra-io/github-misc-called-workflows/.github/workflows/[email protected]) is from a trusted source and doesn't execute arbitrary code from the pull request.- The
PR_APPROVE_AND_MERGE_PATsecret has the minimum required permissions.You can use the following command to check the permissions of the PAT:
gh auth statusEnsure that the token only has the necessary permissions for approving and merging pull requests.
8-11: Job definition looks good, but review the external workflow.Using an external workflow can help maintain consistency across repositories, and pinning the version (
@v0.1.6) is a good practice for stability.Please ensure that:
- The external workflow (
osinfra-io/github-misc-called-workflows/.github/workflows/[email protected]) is from a trusted source.- The contents of the external workflow have been reviewed and are appropriate for your use case.
You can use the following command to view the contents of the external workflow:
gh workflow view https://github.com/osinfra-io/github-misc-called-workflows/blob/v0.1.6/.github/workflows/dependabot.ymlReview the output to ensure it aligns with your expectations and security requirements.
12-13: Good use of secrets, but verify PAT permissions.Using a secret for the Personal Access Token (PAT) is a good security practice.
Please ensure that the
PR_APPROVE_AND_MERGE_PAThas the minimum required permissions. You can check the permissions of the PAT using the GitHub CLI:Verify that the token only has the necessary permissions for approving and merging pull requests, typically:
reposcope for private repositoriespublic_reposcope for public repositoriesworkflowscope if the token needs to trigger other workflowsIf you find that the token has more permissions than necessary, consider creating a new token with only the required permissions.
.github/workflows/add-to-projects.yml (3)
1-9: LGTM: Workflow name and triggers are well-defined.The workflow name is clear and descriptive. The triggers are appropriately set to run only when issues or pull requests are opened, which aligns with the workflow's purpose of adding new items to a GitHub project.
11-12: LGTM: Permissions are correctly scoped.The workflow requests write permissions for issues, which is appropriate and necessary for modifying project boards. The permission is correctly scoped to only what's needed for this workflow's functionality.
14-21: Consider enhancing job configuration for flexibility and clarity.The job configuration looks good overall, but there are a few points to consider:
The job name "Open Source Infrastructure (as Code)" might not accurately reflect its specific function of adding items to a project. Consider a more specific name like "Add Issue/PR to OSInfra Project".
Using a reusable workflow is great for maintainability. However, the version is pinned to v0.1.6. While this ensures stability, it might miss out on future updates. Consider implementing a process to regularly check for and test new versions of the reusable workflow.
The project ID is hardcoded to 1. This might be inflexible if you need to support multiple projects in the future. Consider making this a configurable input if there's a possibility of expanding to multiple projects.
To ensure the workflow is correctly configured, please run the following verification script:

regional/helm/gatekeeper.yml (5)
1-3: LGTM: Datadog service tagging added.The addition of the Datadog service tag is a good practice for enhancing observability. This will help in identifying and monitoring the Gatekeeper service in Datadog.
4-8: Verify intention: Certificate rotation disabled for controller manager.The Datadog tagging for the controller manager is good for granular monitoring. However, disabling certificate rotation (
disableCertRotation: true) could have security implications.Please confirm:
- Is disabling certificate rotation intentional?
- What's the rationale behind this decision?
- Are there alternative measures in place to ensure certificate security?
To help understand the context, let's check for any related configurations or documentation:
#!/bin/bash # Search for related cert rotation configurations or comments rg --type yaml 'disableCertRotation|certificate rotation' -g '!regional/helm/gatekeeper.yml'
9-13: Verify intention: Certificate rotation disabled for audit component.The Datadog tagging for the audit component is consistent and good for monitoring. However, similar to the controller manager, certificate rotation is disabled here (
disableCertRotation: true).Please confirm:
- Is disabling certificate rotation for the audit component intentional?
- Are the reasons the same as for the controller manager?
- How will certificate management be handled for this component?
Let's check for any documentation or comments about this configuration:
#!/bin/bash # Search for documentation or comments about cert rotation in audit rg --type yaml 'audit.*disableCertRotation|certificate rotation.*audit' -g '!regional/helm/gatekeeper.yml'
19-20: LGTM: External certificate injection enabled.Enabling external certificate injection is consistent with the webhook annotations and provides flexibility in certificate management.
To ensure a secure setup, please verify:
- The external certificate injection process is properly configured and secured.
- There are no conflicts with the cert-manager configurations.
- The team is aware of how to manage and troubleshoot external cert injection.
You might want to check for any related configurations or documentation:
#!/bin/bash # Search for related external cert injection configurations or documentation rg --type yaml 'externalCertInjection|external certificate' -g '!regional/helm/gatekeeper.yml'
14-18: LGTM: Webhook annotations for cert-manager CA injection.The addition of validating and mutating webhook annotations for cert-manager CA injection is a good practice. This configuration will help in automating certificate management for the webhooks.
To ensure everything is set up correctly, please verify:
- The existence and proper configuration of the
gatekeeper-webhook-server-certin thegatekeeper-systemnamespace.- The cert-manager is installed and configured in the cluster.
You can use the following command to check the certificate:
.github/workflows/test.yml (2)
1-10: LGTM: Well-defined workflow name and triggers.The workflow name is clear, and the triggers are appropriately set for both manual runs and pull requests. Ignoring Markdown files is a good practice to avoid unnecessary test runs.
12-13: LGTM: Correct permissions for GCP workload identity federation.The
id-token: writepermission is correctly set, which is necessary for workload identity federation with GCP.tests/default.tftest.hcl (1)
24-30: LGTM! Clarify the purpose of this test run and consider adding variables and assertions.The "default_regional_manifests" test run is correctly structured. However:
- It doesn't set any variables, unlike the previous test run. Is this intentional?
- Consider adding assertions to validate the expected outcomes of the apply command.
- It might be helpful to add a comment explaining the specific purpose of this test run and how it differs from "default_regional".
Example of adding variables and an assertion:
run "default_regional_manifests" { command = apply module { source = "./tests/fixtures/default/regional/manifests" } variables { some_variable = "some_value" } assert { condition = output.some_output == expected_value error_message = "The output does not match the expected value" } }Could you clarify the intention behind not including variables in this test run?

5-11: LGTM: pre-commit-hooks configuration is well-structured and up-to-date.The pre-commit-hooks repository is configured with the latest stable version (v5.0.0) and includes essential hooks for maintaining code quality. The selected hooks (check-yaml, end-of-file-fixer, trailing-whitespace, and check-symlinks) are appropriate for general code maintenance.
16-30: LGTM: Well-configured pre-commit-terraform hooks with helpful optimization tip.The pre-commit-terraform configuration is well-structured with appropriate hooks for Terraform code management. The additional arguments for terraform_validate and the exclusion pattern are good practices. The comment about setting TF_PLUGIN_CACHE_DIR is a helpful tip for improving local validation speed.
1-37: Overall, excellent pre-commit configuration for infrastructure-as-code projects.This pre-commit configuration is well-structured and includes a comprehensive set of hooks that will significantly improve code quality, consistency, and security in your project. The inclusion of Terraform-specific hooks and security scanning with checkov is particularly valuable for infrastructure-as-code development.
Consider the suggested version updates and configuration clarifications to further enhance this setup.
34-37:⚠️ Potential issueClarify the use of both verbose and quiet arguments for checkov.
The checkov hook is configured with both
verbose: trueand--quietarguments. These settings seem contradictory as verbose mode typically provides more output, while quiet mode reduces it. Please clarify the intended behavior and consider removing one of these conflicting options.⛔ Skipped due to learnings

48-49: Google client config data source is correctly implementedThe
google_client_configdata source is properly declared and will provide the necessary information, including the access token used in the Kubernetes and Helm provider configurations.This minimal configuration is sufficient for the current use case.
54-61: Clarify the purpose and configuration of the remote stateThe remote state data source is configured to use Google Cloud Storage (GCS) with mock values for the workspace and bucket.
Could you please clarify:
- Is this intentionally using mock values, or should it be updated with real GCS bucket information?
- What is the purpose of this remote state in the context of this configuration?
- Are there any sensitive values that should be handled more securely?
If this is not a test/example configuration, consider updating it with the actual GCS bucket details and using Terraform variables for any sensitive information.
data "terraform_remote_state" "regional" { backend = "gcs" workspace = var.terraform_workspace config = { bucket = var.state_bucket } }Then define these variables in a separate
variables.tffile or pass them securely during Terraform execution.
63-65: Clarify the purpose of the "test" moduleA module named "test" is declared, sourcing its configuration from a relative path. However, the purpose and functionality of this module are not clear from the current context.
Could you please provide more information about:
- The purpose of this "test" module in the overall architecture?
- Whether any input variables should be passed to this module?
Depending on the module's purpose, consider the following improvements:
- Add a comment explaining the module's functionality.
- If applicable, pass relevant input variables to the module.
- Consider using a more descriptive name than "test" if this is not actually a test module.
Example with improvements:
# This module deploys the regional manifests for our application module "regional_manifests" { source = "../../../../../regional/manifests" # Pass relevant variables if needed # variable1 = local.some_value # variable2 = var.some_other_value }
21-31: 🛠️ Refactor suggestionVerify
local.regionalvalues and consider improving readabilityThe Helm provider configuration looks correct, but it relies on
local.regionalvalues which are not defined in this file. Ensure that these values are properly defined, likely in the remote state or another local file.To verify the existence and correct usage of
local.regionalvalues, you can run the following command:For improved readability and maintainability, consider extracting the Kubernetes configuration into a local value. This can help centralize the configuration and make it easier to update:
locals { kubernetes_config = { cluster_ca_certificate = base64decode(local.regional.cluster_ca_certificate) host = local.regional.cluster_endpoint token = data.google_client_config.current.access_token } } provider "helm" { kubernetes { cluster_ca_certificate = local.kubernetes_config.cluster_ca_certificate host = local.kubernetes_config.host token = local.kubernetes_config.token } }This approach can be reused for the Kubernetes provider as well, reducing duplication.

33-43: Kubernetes provider configuration is correctThe Kubernetes provider configuration is well-structured and consistent with the Helm provider. It correctly uses HTTPS for the host URL and properly authenticates with the GKE cluster.
45-49: Google Client Config data source is correctly implementedThe
google_client_configdata source is properly declared and will provide the necessary access token for authenticating with GKE. This is a best practice for working with Google Cloud resources.regional/variables.tf (2)
34-38: LGTM: Chart repository variable is well-defined.The
chart_repositoryvariable is correctly defined with a clear description and an appropriate default value pointing to the official Gatekeeper Helm chart repository.
81-85: LGTM: Node location variable is well-defined.The
node_locationvariable is correctly defined with a clear description and an appropriate default value of null, allowing for flexible node placement across zones when not specified.regional/README.md (3)
10-15: Providers section looks goodThe Providers section clearly lists the required providers (Helm and Kubernetes) along with their versions. This information is valuable for users of the module.
17-29: Modules and Resources sections are well-documentedThe Modules and Resources sections provide a clear overview of the module's composition:
- No submodules are used, which is clearly stated.
- The Resources section lists all managed resources with links to their Terraform registry documentation.
- The resource naming convention is consistent and descriptive.
This information is valuable for understanding the module's structure and functionality.
1-54: Overall, excellent module documentationThis README provides comprehensive and well-structured documentation for the Terraform module. It clearly outlines the module's requirements, providers, resources, and inputs. The use of auto-generated documentation ensures consistency and reduces the likelihood of documentation drift.
While a few minor improvements have been suggested in previous comments, the overall quality of this documentation is high. It follows best practices for Terraform modules and will greatly aid users in understanding and using this module effectively.
Great job on prioritizing clear and thorough documentation!

13-31:helm_valuesblock looks good, verify variable definitionsThe
helm_valuesblock is well-structured and appropriately uses input variables for configuration. This approach allows for flexible customization of the Helm chart deployment.To ensure all variables are properly defined, run the following script:
#!/bin/bash # List all variables used in helm_values variables=$(sed -n 's/.*var\.\([a-zA-Z_]*\).*/\1/p' regional/locals.tf | sort | uniq) # Check if these variables are defined in variables.tf echo "Checking variable definitions..." for var in $variables do if grep -q "variable \"$var\"" variables.tf; then echo "✅ $var is defined" else echo "❌ $var is not defined in variables.tf" fi doneThis script will help you identify any variables that might be missing from your
variables.tffile.
7-11: Reconsider the necessity ofenv_mapIf you implement the regex approach for extracting the environment from
terraform.workspace, theenv_mapmight become unnecessary. However, if you need to translate between full and shortened environment names elsewhere in your code, you may want to keep it.Consider if
env_mapis used elsewhere in your codebase. If not, you might be able to remove it. Here's a script to check for its usage:If the script returns no results (other than this file), you can safely remove the
env_mapblock.✅ Verification successful
env_map is only defined in regional/locals.tf and not used elsewhere
The
env_mapblock is not utilized in any other part of the codebase and can be safely removed if it's no longer needed.🏁 Scripts executed
The following scripts were executed for the analysis:
