terragrunt-generator 0.7.5

generate terragrunt manifest from terraform module.

terragrunt-generator

terragrunt-generator provide a way to generate a terragrunt.hcl file with documented inputs who's coming from variables exposed by terraform module.

The result is easily configurable with a yaml file.

Requirements

• python3.6+

Instalation

$ pip install terragrunt-generator

Usages

Exec

$ terragrunt-generator --help
usage: terragrunt-gernerator [-h] [-V] -u URL [-v VERSION] [-p PATH] [--include | --no-include] [-l LOOKUP]

generate terragrunt.hcl confirugation from terraform module

options:
  -h, --help            show this help message and exit
  -V                    show program's version number and exit
  -u URL, --url URL     the module repository url
  -v VERSION, --version VERSION
                        the module version to use
  -p PATH, --path PATH  define the module path if needed
  --include, --no-include
                        do no rendering the include block
  -l LOOKUP, --lookup LOOKUP
                        define the lookup path

Example

$ terragrunt-generator \
