A bash script for executing terraform within Docker.

terraform_docker.sh

#! /bin/bash

# This script is used to execute terraform commands in the current working directory, using Docker.

# USAGE: ./terraform_docker.sh <init, plan, apply, or any other valid terraform argument>

# NOTE: You will need to ensure this file is executable. You can do this by executing `chmod +x ./terraform_docker.sh`.

#                     !!!!!!!!!!!!!!!!! TERRAFORM CLOUD !!!!!!!!!!!!!!!!!
# NOTE: As written, this script assumes you have a credentials.tfrc.json file, which is 
#       generated via `terraform login`. This may seem like a "chicken & the egg" problem, 
#       given that this script is for executing terraform within docker. However, I wrote 
#       this script to assist developers using Apple Silicon for when they run into roadblocks 
#       with their current Terraform install targeting arm64 builds of Terraform.

# Location of your Terraform Cloud token
TF_CLOUD_TOKEN_FILE=$HOME/.terraform.d/credentials.tfrc.json
PLATFORM=linux/amd64
