Output variables not showing

[Franck Ratier]

Hello!

I wrote a module to setup static websites on AWS and I'd expect it to spit out the name servers from the aws_route53_delegation_set resource.

Everything is applied correctly except that no output is printed. It's no big deal and I can just grep the values in the state file but I don't understand why this doesn't work :/

The module is here.

Cheers,

Franck

Hey Franck –

I took a look at the module you linked too and I didn't see any outputs declared, am I missing something?

Output docs are here:

- https://www.terraform.io/docs/configuration/outputs.html

You can checkout our Best Practices repo to see an example of what I mean here, at the bottom of this file for example:

- https://github.com/hashicorp/best-practices/blob/master/terraform/modules/aws/network/network.tf

Clint

Hi Clint,

Thanks for your reply.

I do have outputs (they were in variables.tf, I moved them to outputs.tf):

output "NS0" {
  value = "${aws_route53_delegation_set.main.name_servers.0}"
}
output "NS1" {
  value = "${aws_route53_delegation_set.main.name_servers.1}"
}
output "NS2" {
  value = "${aws_route53_delegation_set.main.name_servers.2}"
}
output "NS3" {
  value = "${aws_route53_delegation_set.main.name_servers.3}"
}

If I apply again I still get no outputs, and explicitly asking for them returns:

The state file has no outputs defined. Define an output
in your configuration with the `output` directive and re-run
`terraform apply` for it to become available.

But in terraform.state I can see:

                "aws_route53_delegation_set.main": {
                    "type": "aws_route53_delegation_set",
                    "primary": {
                        "id": "N8BY9TYOV8VZT",
                        "attributes": {
                            "id": "N8BY9TYOV8VZT",
                            "name_servers.#": "4",
                            "name_servers.0": "ns-1494.awsdns-58.org",
                            "name_servers.1": "ns-1548.awsdns-01.co.uk",
                            "name_servers.2": "ns-433.awsdns-54.com",
                            "name_servers.3": "ns-716.awsdns-25.net",
                            "reference_name": "Static Websites"
                        }
                    }
                },

Maybe I'm just missing something obvious or maybe it's related to the fact that the config didn't apply properly the first time I ran it: I applied it and it complained about a bug. I didn't fill in a bug report because it finished apply the second time I ran it... My bad, but I saved the debug output so I'll fill in a bug report later on.

Ah, so, the Module has outputs that are defined and those can be consumed by the configs that are using that module, but I don't believe it's expected that they are literally output on the command line. They are "output" to whatever is consuming the module. 

If you wanted to show them on the terminal, you'd need an additional output in whatever config is using the module. To use your example from https://github.com/KifBV/aws-terraform-static-website, in a file that uses that module:

```

output "mod_ns0" {

value = "${module.aws-terraform-static-website.NS0}"

}

```

Does that work?
