Terraform Provider

The terraform provider exposes resources to access state meta data for Terraform outputs from shared infrastructure.

The terraform provider is what we call a logical provider. This has no impact on how it behaves, but conceptually it is important to understand. The terraform provider doesn't manage any physical resources; it isn't creating servers, writing files, etc. It is used to access the outputs of other Terraform states to be used as inputs for resources. Examples will explain this best.

Use the navigation to the left to read about the available resources.

Example Usage

# Shared infrastructure state stored in Atlas
resource "terraform_remote_state" "vpc" {
    backend = "atlas"
    config {
        path = "hashicorp/vpc-prod"
    }
}

resource "aws_instance" "foo" {
    # ...
    subnet_id = "${terraform_remote_state.vpc.output.subnet_id}"
}
