Terraform outputs

First, let's determine what to show. Let's take an example - public IP of the new provisioned instance:

$ terraform console
> aws_instance.dev_node.public_ip
"54.159.150.15"

Or to view more details:

$ terraform state show aws_instance.dev_node

To create the output use the file outputs.tf in the project folder:

output "dev_ip" {
  value = aws_instance.dev_node.public_ip
}

And to not to provision everything from the beginning and only to refresh the state - use the following command:

$ terraform apply -refresh-only

That besically will consider the output and add it to the current state. So we can view it:

$ terraform output
dev_ip = "54.159.150.15"
