'grʌntər
A worker, often in a technical, creative, or professional field, who performs the repetitive, tedious, or less glamorous tasks necessary for a project or operation. This may involve any work deemed necessary but not necessarily requiring high-level decision-making or creativity.
Grunter is a simple Terragrunt file generator. It generates a terragrunt.hcl file from your config.yaml file in the current directory.
It enables you to define your Terragrunt configuration in a simple YAML file, which is easier to read and maintain than the HCL format. It saves you from writing the boilerplate code for each module and keeps your IaaC configuration even DRYer.
It is meant to be used in conjunction with Terragrunt, a thin wrapper for Terraform that provides extra tools for keeping your configurations DRY and managing remote state.
The configuration format is defined here.
go install github.com/romainframe/grunter@latestgrunter genGiven the following config.yaml file:
template: modules/k8s/namespace/default
metadata:
cluster: main
dependencies:
- name: cluster
path: ../../../cluster
pathType: relative
withOutputs: true
- name: env
path: "${local.env}/example-${local.stack_namespace}"
pathType: root
inputs:
name: local.values.locals.name
namespace: local.values.locals.namespaceThe following terragrunt.hcl file will be generated:
# Dependencies
dependency "cluster" {
config_path = "../../../cluster"
skip_outputs = false
}
dependency "env" {
config_path = "${local.env}/example-${local.stack_namespace}"
skip_outputs = true
}
# Locals
locals {
cluster = read_terragrunt_config("../../../services/k8s/main/values.hcl")
# grunted locals = begin
email = get_env("TF_VAR_EMAIL", "")
project = read_terragrunt_config(find_in_parent_folders("project.hcl"))
template_root = get_env("TF_VAR_TEMPLATE_ROOT", "")
values = read_terragrunt_config("values.hcl")
# grunted locals = end
}
# OpenTofu Configuration
terraform {
before_hook "gke-context" {
commands = ["plan", "apply", "destroy", ]
execute = ["bash", "-c", "gcloud config set account ${local.email} && gcloud container clusters get-credentials ${local.cluster.locals.name} --region=${local.cluster.locals.region} --project=${local.project.locals.slug}", ]
}
source = "${local.template_root}//modules/k8s/namespace/default"
}
# Include all settings from the root terragrunt.hcl file
include {
path = find_in_parent_folders()
}
# Inputs to pass to the Terraform module
inputs = {
name = local.values.locals.name
namespace = local.values.locals.namespace
