Terraform modules: source

• https://www.terraform.io/docs/language/modules/sources.html

The source argument in a module block tells Terraform where to find the source code for the desired child module.

• source = "terraform-aws-modules/ec2-instance/aws"

Terraform uses this during the module installation step of terraform init to download the source code to a directory on local disk so that it can be used by other Terraform commands.

Examples in main.tf

module "consul" {
  source = "./path/to/you/module"
}

module "yourmodule" {
  source = "github.com/your-project/terraform-your-templates/modules/yourmodule"
}

module "vpc" {
  source = "git::https://example.com/vpc.git?ref=v1.2.0"
}

module "db" {
 source  = "terraform-aws-modules/rds/aws"
}
