terraform-init-booster

A Pre-terraform routine that speedups terraform modules download for bulky blueprints.

Problem statement

• Terraform v0.12.x and older downloads module from git source for every usage (https://github.com/hashicorp/terraform/issues/11435). For bulky blueprints with hundreds of similar modules that make the process of terraform init slow.

Installation

pip install tf-init-booster

Quickstart

(blueprint folder)>tf-init-booster
(blueprint folder)>terraform init

Settings with environment variables

• LOGLEVEL=INFO
• GIT_PATH=/usr/bin/git

Indications for use

• Git as module source
• Many modules with the same source

Performance

Based on a blueprint with 580 modules, 10 of them unique.

• Pure terraform init - 3m08s
• Boosted + terraform init - 39s (2.7s + 36.5s)

Compatibility

Designed for terraform v0.12 and v0.11

Requrements

• Python 3.6+
• (optional) gitpython * module

* otherwise, system git will be used
