## Overview

This module provides ability to create multiple lambda functions.

## Pre-Commit hooks

[.pre-commit-config.yaml](.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)](https://github.com/conventional-changelog/commitlint/tree/master/@commitlint/config-conventional#type-enum)

If you are a developer using vscode, [this](https://marketplace.visualstudio.com/items?itemName=joshbolduc.commitlint) 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](https://pre-commit.com/#install) 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`](./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
