• Controlled Remote State Access feature in Terraform Cloud and Terraform Enterprise, users now have a new way to establish granular controls for state accessibility.

Example Usage (remote Backend)

data "terraform_remote_state" "vpc" {
  backend = "remote"

  config = {
    organization = "hashicorp"
    workspaces = {
      name = "vpc-prod"
    }
  }
}

# Terraform >= 0.12
resource "aws_instance" "foo" {
  # ...
  subnet_id = data.terraform_remote_state.vpc.outputs.subnet_id
} 

# Terraform <= 0.11
resource "aws_instance" "foo" {
  # ...
  subnet_id = "${data.terraform_remote_state.vpc.subnet_id}"
}

Example Usage (local Backend)

data "terraform_remote_state" "vpc" {
  backend = "local"

  config = {
    path = "..."
  }
}

# Terraform >= 0.12
resource "aws_instance" "foo" {
  # ...
  subnet_id = data.terraform_remote_state.vpc.outputs.subnet_id
}

# Terraform <= 0.11
resource "aws_instance" "foo" {
  # ...
  subnet_id = "${data.terraform_remote_state.vpc.subnet_id}"
}
