Terraform Scaffold (terraform-scaffold)

Simple Terraform scaffold repo for the base of your projects.

Overview

Un-opinionated lightweight scaffolding of a basic terraform repo. Deliberately lightweight (& for the time being un-finished).

Yes there is a considerable amount more I could be doing with tf.sh & I may well add to that over the coming months. Most projects will not require additional complexity.

Usage

Bootstrap

You can get setup using an s3 bucket as backend for terraform simply with the following. Be sure to check the variables.tf defaults and override them if you like.

cd terraform/bootstrap
terraform init
terraform plan -out tfplan.out
terraform apply "tfplan.out"

Plan

dev plan >

cd bin/
./tf.sh plan dev eu-west-1

cd bin/
./tf.sh plan prod eu-west-1

To do

  • Add better examples in environments
  • Show how components can be shared to the environment workspaces
  • Allow for variables to be passed to the final terraform cmd from the bin/tf.sh wrapper
  • Improve the bin/tf.sh wrapper
    • nice args
    • var passing to underlying cmd
    • pre-flight checks
    • input validation
