Ansible AnsibleUndefinedVariable: 'XX is undefined

Can anyone please help me here, I have a playbook which has the following vars:

  vars_files:
    - "../vars/location.yml"

The location.yml has the following declared:

  loc: "{{ inventory_hostname[0:3] }}"
  location_file: "/root/ansible/vars/{{ loc }}.yml"

So from hostname location_file: is then prd.yml, this file contains the line:

txm_QA_access: false

Now if I run the playbook which copies a sudoers template with the following conditional specified in it:

{% if txm_QA_access %}
%Sudo-admin ALL= /bin/su - admin
%Team-QA ALL= /bin/su - admin
%Team-QA\ OffShore\ \(UK\) ALL= /bin/su - admin
{% endif %}  `

When I run the playbook I get an error:

"msg": "AnsibleUndefinedVariable: `txm_QA_access` is undefined"

Where am I going wrong? Isn't it defined as a Boolean which is false so in theory it should skip adding those lines in the sudoers template?

Any help appreciated spent hours on this now.

I guess this is because the vars file prd.yml (most likely) is not getting loaded. And as @dechandler10 mentioned, you can use include_vars:, instead of vars_files:.

In your playbook you have already included location.yml, next you should include vars from prd.yml before the template task.

  vars_files:
    - '../vars/location.yml'

  tasks:
    # Your 'location_file' variable set to: /root/ansible/vars/prd.yml
    - name: include variables
      include_vars:
        file: '{{ location_file }}'

Now that your prd.yml has been included, the variable txm_QA_access will be available for template.

However, Ansible already has built-in mechanism called group_vars and host_vars.

Instead of having to define variable paths with inventory_hostname[0:3], Ansible can directly load variables for hosts or groups with this method. See organizing host and group variables.

You didn't mention doing anything to include the variables in prd.yml, so I'm going to assume you haven't. You'll need to use include_vars to load the variables from that file.

If you are doing that, I recommend adding debug tasks immediately before your template task to sort out exactly which variable is causing the problem.
