Contributing

This guide will help you get started contributing to this repo, with instructions to setup your development environment and tips when developing.

Setup

There are some dependencies that are required to be able to run the linters, checks and formatting. The following tools are required to be installed on your local development machine to run the validation. A tip is to use your favorite flavor of package manager like brew or pacman to make the process simpler.

If you are using macOS you will need to install a newer version of make, as the one included by default is soon legally allowed to drink in Germany. The new make version will not remove the existing one but instead install it as the command gmake.

brew install make

Development

Eeach PR has a set of checks that are required to pass before it can be merged. This is to ensure consitency and stability in each of the modules. You should run through all the make recipes before creating a PR to make sure that all of your HCL is formatted correctly.

make
# or on macOS
gmake

Creating a Module

Creating a new module is simple but has some non-obvious requirements for all of the checks to pass. First create a new module directory in the 'modules' directory and in a fitting category directory. After the module is created a validation configuration needs to be created for the module. In the 'validation' directory create a new directory with the same name and path as the module. Inside there you should create a main.tf file which imports the module with a local path and passes dummy values for all of the required variables, so that it is possible to run terraform validate.

Your First Pull Request

These are the steps someone without contributor access needs to take to create a pull request:

  1. Fork the repository using the GitHub
  2. If you already have a fork, make sure it is up-to-date by pressing "Sync fork" in GitHub
  3. Clone your fork to your local computer git clone <github repo>
  4. Start a terminal inside the local repository and create a branch git checkout -b <branch-name>
  5. Make all the neccesary changes
  6. Make sure you have the neccesary tools installed locally to run the make commands. See LOCAL_DEVELOPMENT for more details.
  7. Run make all and make sure nothing fails
  8. Stage the changes using git add <file> (use git status to see all changed files)
  9. Commit the changes using git commit and write a respectable commit message
  10. Push the changes using git push --set-upstream origin <branch-name>
  11. Go to your GitHub repository and pres "Compare & pull request"
  12. Choose the correct base repository (should be XenitAB/terraform-modules main branch)
  13. Make sure your commits and PR title conforms to conventional commits, where type should be one of feat,fix,docs,test,ci,refactor,perf,chore, or revert. Using a scope is optional. If used, it can be the module, using the following format: module group/module. Example: fix(azure/core): <subject>
  14. Make sure you allow edits by maintainers
  15. Then press Create pull request
  16. INFO: A maintainer will be required to approve the checks to run before you will receive feedback from them
  17. When all checks are passing and you have received an approval and a maintainer have merged the changes, press "Delete branch" in the PR
  18. Locally, in the terminal, check out main using git checkout main
  19. Remove the local branch using git branch -D <branch-name>
  20. In your GitHub fork, press "Sync fork"
  21. Locally, run git pull
