CLI Tool to configure Terraform Cloud Workspaces and Git Repos

TerraChicken (Terra🐓)

Terrachicken is a cli tool for interacting with Terraform Cloud Workspaces. Terra🐓 allows users to create, list, and delete TFC Workspaces. Terra🐓 supports configuring VCS backed workspaces for Github and Gitlab (Future Version). Terra🐓 was developed to help solve the 🐓 and 🥚 problem with Terraform Cloud automation. Allowing developers and practitioners an easy way to create and destroy workspaces from the command line. Terra🐓 even generates Terraform Backend configurations. This project was created to help solve problems but more so to learn Python and CLI development

Prerequisites

1. Python 3.6+
2. Terraform Cloud Account Here - Free Account Works
3. Github Account

Installation

To install Terra🐓 you can pull the package down for PyPi with the pip using the command below Note Terra🐓 uses libraries that have a hard dependency on Python 3.6+. You will need to have that version or newer

pip install terrachicken

Configuration

TerraChicken only supports Environment Variables currently. Future versions will have built in functionality to support initial configuration.

1. Environment Variables

Environment Variables

• TFC_TOKEN - API Token generated from Terraform Cloud Settings.
• TFC_URL - Terraform Cloud URL (app.terraform.io) unless using Terraform Enterprise
• TFC_ORG - Terraform Cloud Organiztion Name
• GIT_TOKEN - Github Developer Access Token (Repo CRUD Perms at minimum)

To set an environment token use the following export TFC_URL='app.terraform.io'

Hint: After you set your tokens. You can install the built in auto completion with the terrachicken --install-completion command.

Using Terra🐓

Creating Workspaces

Terra🐓 supports creating Local and VCS or Version Control System (Github/Gitlab) workspaces.

Local Workspaces

Example:

terrachicken create workspace local

You will be prompted to enter a name for your workspace. After a successful completion your new Workspace ID will be printed to the terminal.

VCS Workspace

terrachicken create workspace vcs

Note: The Github OAuth provider must be configured in Terraform Cloud prior to building VCS workspaces.

Creating a VCS backed workspace requires you to either create a repo or link and existing repo to the workspace. The default is to create a Github Repo along side the workspace.

Generating Terraform Block Configurations

Example:

terrachicken create workspace vcs --name TerrachickenTest1 --generate

Example rendered_main.tf:

terraform {
  cloud { 
    organization = "aBakersDozen"

    workspaces {
      name = "TerrachickenTest1"
    }
  }
}

Both create workspace local and create workspace vcs support generating a Terraform Block configuration to be implemented inside of your Terraform code. To read more about the Terraform Block Syntax click here. Using the --generate or -g option at the end of the command will output a rendered_main.tf file to your current working directory.

The Terraform Block settings will differ based on your workspace type. If you are creating a local workspace. The configuration sets backend with your workspace name. If you are creating a vcs workspace the configuration sets the cloud block. To use the VCS generated main.tf file, you will need to run the terraform login command if you want to execute cli commands for terraform. Click here to read about cloud block and terraform login.

Create Workspace VCS Options

• --name: Name of Workspace
• --generate: Generate Terraform Block Configuration
• --out: Exports TFC Configuration via payload.json
• --tfversion: Set Terraform Version in Workspace
• --create_repo: Create Repo or nah
• --private: Set Github Repo to Private
• --public: Set Github Repo to Public

TO-DO

2. terrachicken init command allows you to add your tokens. Note If you are using an Env Var labeled TFC_TOKEN , TFC_URL or GIT_TOKEN. Those ENV Vars will take priority

TO-DO: Add TC backstory TO-DO: Add init configurations to set default OAuth Client TO-DO: Add --repo flag to copy --name flag TO-DO: Add Gitlab VCS Options TO-DO: Remove the utils.bcolors class, sub for the rich library TO-DO: Add option to delete workspace and repo at same time. TO-DO: Add more options to the TF Workspace Configuration.
