1-27: LGTM!The code changes are approved. The new
Identityclass is well-structured and correctly generates the Terraform resource block forcpln_identity.lib/patches/string.rb (1)
21-23: LGTM!The code changes are approved. The new
underscoremethod is a useful utility for string manipulation and the regular expression correctly converts the string to underscore case.spec/core/terraform_config/identity_spec.rb (1)
1-36: LGTM!The code changes are approved. The new spec for the
Identityclass is well-written and covers the important aspects of the class. The use of a heredoc makes the spec readable and easy to understand. The spec passes and ensures that theto_tfmethod generates the correct Terraform config.spec/command/terraform/generate_spec.rb (2)
12-12: LGTM!The change enhances the test setup by providing a test app for each test case.
25-32: LGTM!The changes enhance the test coverage by checking for multiple config files and improve the robustness of the test by using
:aggregate_failures.lib/command/terraform/generate.rb (3)
20-27: LGTM!The changes enhance the command's capability to generate terraform configs dynamically based on the provided templates. The conditional check adds a layer of validation to the template handling.
36-39: LGTM!The method introduces a new dependency on the
TemplateParserclass to parse YAML template files from a specified directory.

🧹 Outside diff range and nitpick comments (5)
spec/command/terraform/generate_spec.rb (3)
12-12: LGTM! Consider adding a comment for clarity.The addition of
let!(:app)is a good practice for setting up the test environment. It ensures that the dummy app is created before each test run.Consider adding a brief comment explaining what
dummy_test_apprepresents, as it's not defined in this file:# Create a dummy application instance for testing let!(:app) { dummy_test_app }
24-28: Improved test case with better assertions and error aggregation.The changes to the test case are excellent:
- Adding
:aggregate_failuresallows all expectations to be evaluated, improving test coverage.- Checking for non-existence of files before running the command ensures a clean state.
- Using
all(exist)provides a clear and concise way to check all generated files.Consider adding a descriptive comment for the test case to explain its purpose:
# Ensures that the command generates all expected Terraform config files it "generates terraform config files", :aggregate_failures do # ... (rest of the test case) end
30-33: Well-structured helper method for managing config file paths.The
config_file_pathsmethod is a great addition:
- It centralizes the logic for determining expected file paths.
- It improves maintainability and reduces duplication in the test.
- The method is flexible, allowing for easy addition of new config files in the future.
Consider adding a brief comment explaining the method's purpose and return value:
# Returns an array of Pathname objects for all expected Terraform config files def config_file_paths [TERRAFORM_CONFIG_DIR_PATH.join("providers.tf")] + %w[gvc.tf identities.tf].map do |config_file_path| TERRAFORM_CONFIG_DIR_PATH.join(app, config_file_path) end endlib/command/base.rb (1)
457-468: LGTM! Consider enhancing with path validation and a more detailed description.The
dir_optionmethod is a well-structured addition that follows the existing pattern for option methods in the class. It provides flexibility with therequiredparameter and uses appropriate types for the directory option.To further improve this method, consider the following suggestions:
- Add path validation to ensure the provided directory is valid and accessible.
- Expand the description to provide more context, e.g., "Specify the output directory for generated files".
Here's a suggested enhancement to the method:
def self.dir_option(required: false) { name: :dir, params: { banner: "DIR", desc: "Specify the output directory for generated files", type: :string, required: required, validate: ->(value) { Dir.exist?(value) || raise("Directory does not exist: #{value}") } } } endThis change adds a simple validation to check if the directory exists and provides a more informative description.
lib/command/terraform/generate.rb (1)
52-52: Review the file write mode for clarityThe
File.writemethod is usingmode: "a+", which opens the file in read-write mode and appends content to it:File.write(terraform_app_dir.join(generator.filename), generator.tf_config.to_tf, mode: "a+")Since the application directory is recreated each time with
recreate_terraform_app_dir, and files within it are removed, using append mode might not be necessary.Consider using the default write mode (
"w"), which truncates the file before writing. This can prevent potential confusion and ensures that each generation produces a fresh set of configuration files:-File.write(terraform_app_dir.join(generator.filename), generator.tf_config.to_tf, mode: "a+") +File.write(terraform_app_dir.join(generator.filename), generator.tf_config.to_tf)If there is a specific reason for using append mode (e.g., multiple writes to the same file within a single run), please ensure that this behavior is documented to avoid confusion.

spec/command/terraform/generate_spec.rb (1)
14-16: Improved file cleanup in thebeforeblock.The change from
FileUtils.rm_rtoFileUtils.rm_rfis a good improvement. It ensures a more robust cleanup process before each test by forcibly removing the directory and its contents, even if it doesn't exist.lib/command/base.rb (1)
470-472: LGTM! The newdir_optionis automatically included inall_options.The
all_optionsmethod uses metaprogramming to collect all methods ending with_option. This approach ensures that the newly addeddir_optionis automatically included without requiring any changes to theall_optionsmethod itself.This demonstrates good use of metaprogramming for extensibility, making it easy to add new options in the future without modifying existing code.
lib/command/terraform/generate.rb (2)
49-50: 🛠️ Refactor suggestionRemove hardcoding of template kinds to support extensibility
Currently, the code skips processing templates unless their
kindis either'gvc'or'identity':next unless %w[gvc identity].include?(template["kind"])Hardcoding template kinds can hinder future extensibility when new template types are added.
Consider handling all available template kinds dynamically or configuring the list of supported kinds. If certain kinds are not yet supported, you could log a warning or handle them appropriately.
Given the TODO comment indicates that this line should be deleted after all template kinds are supported, ensure that there is a plan to implement support for additional kinds. To verify if there are other template kinds present in the templates directory, you can run the following script:
#!/bin/bash # Description: Check for template kinds other than 'gvc' and 'identity' in templates/*.yml # Expected: No output if only 'gvc' and 'identity' are used. rg '^kind:' templates/*.yml | sed 's/.*kind: //' | sort | uniq | grep -v -E '^(gvc|identity)$'This script searches for all
kindentries in your template files and lists any that are not'gvc'or'identity'. If the script outputs any kinds, it means there are templates that are currently being skipped and need to be supported or handled accordingly.
71-73: Ensure the terraform directory path is correctly resolvedWhen fetching the
:diroption fromconfig.options, if the provided path is relative, it might not resolve correctly:full_path = config.options.fetch(:dir, Cpflow.root_path.join("terraform"))Verify that when a relative path is provided via the
:diroption, it is correctly expanded relative to the current working directory or the application's root path. If not, consider expanding it usingFile.expand_pathor resolving it against a known base path.To confirm this behavior, you can run the following script:
This will show how relative paths are resolved in your environment and help ensure that the terraform directory is created in the intended location.

@zzaakiirr Actually, this line is causing issues in the tests, and may be affecting other areas as well:
When doing the cleanup at the end of the tests, it tries to delete the incorrect app, because the app method has been overwritten and won't return the correct app:
This is why apps aren't being properly cleaned after running the tests.
We need to think of a better way to handle this.
@rafaelgomesxyz Thanks for finding problematic place in the code! I replaced Both specs passed and test GVCs were deleted in controlplane. Without this fix |
