Terraform Module - Output Returns Empty after Successful Run.

[Bharath Annamaneni]

Hello Ansible Users,

I am trying to run/use the Ansible's Terraform Module to provision the servers in Public Cloud. The Terraform Code works fine when run manually and through Ansible, but, the Ansible doesn't return the output of the resources being provisioned by Terraform.

Per Ansible's Terraform Module documentation it is expected to return a "output" key on success with the details of the resources being provisioned. But, in my case its empty.


play.yml

- hosts: localhost

  gather_facts: false

  become: false

  tasks:

  - name: Provision AWS

    community.general.terraform:

     project_path: "/home/terraform/aws-vm"

     state: present

     force_init: true

     variables:

      type: t2.micro

    register: terraform

  

  - debug:

      var: terraform


Output:
ok: [localhost] => {
    "terraform": {
        "changed": true,
        "command": "/usr/bin/terraform apply -no-color -input=false -auto-approve=true -lock=true /tmp/tmp5plmx0xb.tfplan",
        "failed": false,
        "outputs": {},

        "stderr": "",
        "stderr_lines": [],

            "",
            "State path: terraform.tfstate"
        ],
        "workspace": "default"
    }
}

Can anyone please help me resolving the issue.

What ansible documentation say is that the terraform ansible module ouputs Terraform outputs https://www.terraform.io/docs/configuration/outputs.html

If you don't have any Terraform output declared in your .tf files you won't see any output.
