Terraform Output

The terraform output command is used to extract the value of an output variable from the state file.

Usage: terraform output [options] [NAME]

With no additional arguments, output will display all the outputs for the root module. If an output NAME is specified, only the value of that output is printed.

The command-line flags are all optional. The list of available flags are:

  • -json - If specified, the outputs are formatted as a JSON object, with a key per output. If NAME is specified, only the output specified will be returned. This can be piped into tools such as jq for further processing.
  • -state=path - Path to the state file. Defaults to "terraform.tfstate". Ignored when remote state is used.
  • -module=module_name - The module path which has needed output. By default this is the root path. Other modules can be specified by a period-separated list. Example: "foo" would reference the module "foo" but "foo.bar" would reference the "bar" module in the "foo" module.


let's create a file with tf extension with below content.

provider "github" {
resource "github_repository" "terraform-first-repo" {
  name        = "first-repo-from-terraform"
  description = "My First resource for my youtube viewers."
  visibility  = "public"
  auto_init   = true
output "terraform-repo-url" {
  value = github_repository.terraform-first-repo.html_url

now run terraform init, terraform apply after that let's try with terraform output.

└─$ terraform output terraform-repo-url
