terraform-module-tree

This cli takes a workloads.json file that contains an array with absolute paths to terraform root modules. E.g.

[
    "C:\\work\\git\\myproject\\Infrastructure\\main-infrastructure\\Workloads\\eslz\\Environments\\prd",
    "C:\\work\\git\\myproject\\Infrastructure\\main-infrastructure\\Workloads\\app\\Environments\\dev",
    "C:\\work\\git\\myproject\\Infrastructure\\main-infrastructure\\Workloads\\app\\Environments\\local"
]

Run it as follows:

terraform-module-tree workloads.json

There is an npm package published which you can run as follows with only nodejs as a prerequisite:

npx -y @cveld/terraform-module-tree@0.0.1-preview.4 -- workloads.json

It starts crawling all those root modules and spits out a json with a map of all crawled folders towards a list of all root modules that use this folder.

E.g.

{
 "C:\\work\\git\\myproject\\Infrastructure\\main-infrastructure\\Modules\\app-configuration": [
  "C:\\work\\git\\myproject\\Infrastructure\\main-infrastructure\\Workloads\\app\\Environments\\dev",
  "C:\\work\\git\\myproject\\Infrastructure\\main-infrastructure\\Workloads\\app\\Environments\\local"

}

This output can be used in combination with the output of git diff --name-status HEAD~1 HEAD to detect which root modules require a terraform plan.
