terramer's Introduction

Terramer: Terraform + Mermaid markup

Extend the terraform graph command to generate mermaid diagrams.

State

Very early code. A lot more ideas than code really.

Excuse golang noob-ness: this is my excuse to re-learn golang inspired by the masters: https://github.com/hashicorp/terraform/.

Currently using terraform as a library following this code: https://github.com/johandry/platformer/blob/master/platformer.go As we get to learn the terraform code better, we may end-up with a different mechanism to get into the customize the graph output command.
