Terraform modules: source
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"
}
