Terrap, by Sirrend

Simplify your Provider version upgrades with Terrap - a powerful CLI tool that scans your system and identifies any required changes.
The tool offers clear and actionable notifications, helping you streamline the upgrade process and avoid any potential errors or complications.

🔍 Terrap is an alpha version project, therefore some data might be partial.

Constraints 🧱

1. Supported Terraform Core versions: >=0.13.
2. Every provider which uses Terraform Core 0.13 or higher.

Good To Know 💡

Terrap decides which Terraform version to use in the following order:

1. The latest installed Terraform version found locally.

2. If the TERRAP_TERRAFORM_VERSION environment variable is set, Terrap will use the version specified as long as it matches the >=0.13 constraint.
   Set environment variable on mac/linux:
   

   export <var>=<value>

   Set environment variable on windows:
   

   $Env:TERRAP_TERRAFORM_VERSION = "0.13"

3. If none of the above is applicable, Terrap will download the latest available version.

How to Download ⬇️

cd terrap-cli

go build -o terrap .

chmod +x terrap

Validate terrap is working by executing terrap.

Quick Start ⏩

Initialize my First Workspace

1. CD to the local Terraform folder you want to work with.
   cd < /terraform/folder/path >
   
   

2. Initialize a new Terrap workspace where you would run terraform apply with terrap init.
   
   Important!
   As Terrap runs terraform init under the hood, it would need every configuration component you normally use when executing the command.
   It can be environment variables, the .aws/credentials file, etc.

3. Scan your workspace with: terrap scan
