Overview

What does this module do?

Pre-Commit hooks

.pre-commit-config.yaml file defines certain pre-commit hooks that are relevant to terraform, golang and common linting tasks. There are no custom hooks added.

commitlint hook enforces commit message in certain format. The commit contains the following structural elements, to communicate intent to the consumers of your commit messages:

• fix: a commit of the type fix patches a bug in your codebase (this correlates with PATCH in Semantic Versioning).
• feat: a commit of the type feat introduces a new feature to the codebase (this correlates with MINOR in Semantic Versioning).
• BREAKING CHANGE: a commit that has a footer BREAKING CHANGE:, or appends a ! after the type/scope, introduces a breaking API change (correlating with MAJOR in Semantic Versioning). A BREAKING CHANGE can be part of commits of any type. footers other than BREAKING CHANGE: may be provided and follow a convention similar to git trailer format.
• build: a commit of the type build adds changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
• chore: a commit of the type chore adds changes that don't modify src or test files
• ci: a commit of the type ci adds changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
• docs: a commit of the type docs adds documentation only changes
• perf: a commit of the type perf adds code change that improves performance
• refactor: a commit of the type refactor adds code change that neither fixes a bug nor adds a feature
• revert: a commit of the type revert reverts a previous commit
• style: a commit of the type style adds code changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
• test: a commit of the type test adds missing tests or correcting existing tests

Base configuration used for this project is commitlint-config-conventional (based on the Angular convention)

If you are a developer using vscode, this plugin may be helpful.

detect-secrets-hook prevents new secrets from being introduced into the baseline. TODO: INSERT DOC LINK ABOUT HOOKS

In order for pre-commit hooks to work properly

• You need to have the pre-commit package manager installed. Here are the installation instructions.
• pre-commit would install all the hooks when commit message is added by default except for commitlint hook. commitlint hook would need to be installed manually using the command below

pre-commit install --hook-type commit-msg

To test the resource group module locally

1. For development/enhancements to this module locally, you'll need to install all of its components. This is controlled by the configure target in the project's Makefile. Before you can run configure, familiarize yourself with the variables in the Makefile and ensure they're pointing to the right places.

make configure

This adds in several files and directories that are ignored by git. They expose many new Make targets.

2. THIS STEP APPLIES ONLY TO MICROSOFT AZURE. IF YOU ARE USING A DIFFERENT PLATFORM PLEASE SKIP THIS STEP. The first target you care about is env. This is the common interface for setting up environment variables. The values of the environment variables will be used to authenticate with cloud provider from local development workstation.

make configure command will bring down azure_env.sh file on local workstation. Devloper would need to modify this file, replace the environment variable values with relevant values.

These environment variables are used by terratest integration suit.

Service principle used for authentication(value of ARM_CLIENT_ID) should have below privileges on resource group within the subscription.

"Microsoft.Resources/subscriptions/resourceGroups/write"
"Microsoft.Resources/subscriptions/resourceGroups/read"
"Microsoft.Resources/subscriptions/resourceGroups/delete"

Then run this make target to set the environment variables on developer workstation.

make env

3. The first target you care about is check.

Pre-requisites Before running this target it is important to ensure that, developer has created files mentioned below on local workstation under root directory of git repository that contains code for primitives/segments. Note that these files are azure specific. If primitive/segment under development uses any other cloud provider than azure, this section may not be relevant.

• A file named provider.tf with contents below

provider "azurerm" {
  features {}
}

• A file named terraform.tfvars which contains key value pair of variables used.

Note that since these files are added in gitignore they would not be checked in into primitive/segment's git repo.

After creating these files, for running tests associated with the primitive/segment, run

make check

If make check target is successful, developer is good to commit the code to primitive/segment's git repo.

make check target

• runs terraform commands to lint,validate and plan terraform code.
• runs conftests. conftests make sure policy checks are successful.
• runs terratest. This is integration test suit.
• runs opa tests

Resources

Name	Type
azurerm_virtual_machine_extension.virtual_machine_extension	resource

Inputs

Name	Description	Type	Default	Required
name	(Required) The name of the virtual machine extension peering. Changing this forces a new resource to be created.	string	n/a	yes
virtual_machine_id	(Required) The ID of the Virtual Machine. Changing this forces a new resource to be created	string	n/a	yes
publisher	(Required) The publisher of the extension, available publishers can be found by using the Azure CLI. Changing this forces a new resource to be created.	string	n/a	yes
type	(Required) The type of extension, available types for a publisher can be found using the Azure CLI.	string	n/a	yes
type_handler_version	(Required) Specifies the version of the extension to use, available versions can be found using the Azure CLI.	string	n/a	yes
auto_upgrade_minor_version	(Optional) Specifies if the platform deploys the latest minor version update to the type_handler_version specified.	bool	false	no
automatic_upgrade_enabled	(Optional) Should the Extension be automatically updated whenever the Publisher releases a new version of this VM Extension?	bool	false	no
settings	(Optional) The settings passed to the extension, these are specified as a JSON object in a string. Changing this forces a new resource to be created.	string	n/a	yes
failure_suppression_enabled	(Optional) Should failures from the extension be suppressed? Possible values are true or false.	bool	false	no
protected_settings	(Optional) The protected_settings passed to the extension, like settings, these are specified as a JSON object in a string.	string	null	no
protected_settings_from_key_vault	(Optional) Map of protected settings from Key Vault. Can not be used with protected_settings	object({ secret_url = string source_vault_id = string })	null	no
