Creating Terraform Output

This is a simple Bash script that reads through your Terraform DSL code and spits out syntax compliant terraform output code. Using this script eases maintaining output stanzas, ensures you don't miss a new resource and eliminates needing to remove obsolete outputs. Every resources will have a output created that returns it's ID (not ARN) for the related service.

create-terrafrom-output.sh accepts only one command, plan, and a single path passed presently; ie: create-terrafrom-output.sh plan <path_to_.tf_files>. The resulting code is printed to stdout. This is convenient as you can review the code first and then pipe it to a file to be included in the next terrafrom apply. Script errors are conveniently printed to stderr so that you can see them even when piping stdout. Running the script dry will print out it's help.

Requirements

• Terrafrom client
• Bash

Tested on Mac OS 10.11.4 and Ubuntu 14.04 LTS.
