Makefile for Terraform users

This repository provides a Makefile to give you a simple interface for Terraform.

Why?

• Simplify your CLI terraform runs
• Don't Repeat Yourself while typing terraform commands
• Easier adoption for people that are not used to Terraform
• Document common usage
• Unique entrypoint script for credentials management (only for AWS, Azure, DigitalOcean, Google, Hetzner and Scaleway for now)
  • either passing ENV variables. E.g. <PROVIDER>_<ENV>_SECRET will be mapped to DIGITALOCEAN_TOKEN if provider=do is provided as variable
  • either using pass as local secret manager. E.g. password terraform/<provider>/<env>/secret will be mapped to DIGITALOCEAN_TOKEN if provider=do is provided as variable
  • either using vault as distributed secret manager (Only for AWS credentials for now). E.g. by using VAULT_ADDR and either VAULT_ROLE_ID + VAULT_SECRET_ID or directly a VAULT_TOKEN your credentials will automatically be fetched into your vault.

Installation

Package install

(for now packages are only published in Github releases)

wget https://github.com/paulRbr/terraform-makefile/releases/download/<version>/tf-make_<version>_amd64.deb
dpkg -i tf-make_<version>.deb

Manual install

Simply download the Makefile and the terraform.sh files in safe place.

mkdir -p /opt/terraform
cd /opt/terraform
wget -N https://raw.githubusercontent.com/paulRbr/terraform-makefile/master/{Makefile,terraform.sh}

Then you will need to add the tf-make binary (it's a simple bash script) in your $PATH. WARNING: you'll need to change the Makefile path in the tf-make file.

Convention

This makefile assumes your terraform configuration files are stored in a specific directory structure:

I.e. providers/<provider>/<env>/*.tf

E.g. example for all supported providers:

providers/
├── aws
│   ├── prod
│   │   └── config.tf
│   └── test
│       └── config.tf
├── do
│   └── prod
│       └── config.tf
├── google
│   ├── prod
│   │   └── config.tf
│   └── test
│       └── config.tf
├── hetzner,scaleway
│   └── test
│       └── config.tf
├── hetzner
│   └── prod
│       └── config.tf
└── scaleway
    └── prod
        └── config.tf

Note: the provider name can be a combination of multiple providers when you are in a multi-cloud environment. E.g. providers/hetzner,scaleway/prod/config.tf.
