Terraform Modules

This repository is a collection of Terraform modules which you can use in your own Terraform code. This makes it easy to follow the principles of infrastructure as code.

Usage

Usage is as follows:

Provider Config (Kowl + Kowl Business)

Put the provider configuration into the root module and pass the providers to your Kowl modules.

provider "google" {
  version = "~> 3.36.0"
}

provider "random" {
  version = "~> 2.3.0"
}

data "google_client_config" "provider" {}

  name     = "dev"
  location = "europe-west1-c"
  project  = "cloudhut-dev"
}

provider "kubernetes" {
  version = "~> 1.12"
  alias   = "cloudhut_dev"

}
