Is there a way of using output values of a module that is located in another folder? Imagine the following environment:
tm-project/
├── lambda
│ └── vpctm-manager.js
├── networking
│ ├── init.tf
│ ├── terraform.tfvars
│ ├── variables.tf
│ └── vpc-tst.tf
├── prd
│ ├── init.tf
│ ├── instances.tf
│ ├── terraform.tfvars
│ └── variables.tf
└── security
└── init.tf
I want to create EC2 instances and place them in a subnet that is declared in networking folder. So, I was wondering if by any chance I could access the outputs of the module I used in networking/vpc-tst.tf as the inputs of my prd/instances.tf.
Thanks in advances.
You can use a outputs.tf file to define the outputs of a terraform module. Your output will have the variables name such as the content below.
output "vpc_id" {
value = "${aws_vpc.default.id}"
}
These can then be referenced within your prd/instances.tf by referencing the resource name combined with the output name you defined in your file.
For example if you have a module named vpc which uses this module you could then use the output similar to below.
module "vpc" {
......
}
resource "aws_security_group" "my_sg" {
vpc_id = module.vpc.vpc_id
}
