Terraform: output

• https://www.terraform.io/docs/language/values/outputs.html

• A child module can use outputs to expose a subset of its resource attributes to a parent module.
• A root module can use outputs to print certain values in the CLI output after running terraform apply.
• When using remote state, root module outputs can be accessed by other configurations via a terraform_remote_state data source.

Examples

Official example

output "instance_ip_addr" {
  value = aws_instance.server.private_ip
}

Additional examples

output "your_output_value" {
   value = XXXX
}

Using sensitive value will not be printed on screen but will still be recorded in the state files.

sensitive   = true
