With ansible I am using j2 templates to replace files, and pass through environment vars unique to each environment and some shared. Neither the variables for global or local work. I have the following set-up and structure.

The directory structure

/project
/project/playbooks
/project/playbooks/do-something.yaml
/project/playbooks/templates
/project/playbooks/templates/myfile.json.j2
/project/vars
/project/vars/config_vars.yaml
/project/inventory.ini

Inventory file

inventory.ini

[myhosts]
host1 ansible_host=192.168.1.10

Config Vars file

vars/config_vars.yaml

all:
  vars:
    my_value_one: "value1"
  children:
    myhosts:
      hosts:
        host1:
          my_value_two: "value2"

Playbook file

playbooks/do-something.yaml

---
- name: Configure Nodes
  hosts: myhosts
  become: yes
  vars_files:
    - ../vars/config_vars.yml
 tasks:
    - name: Replace file with j2 template
      template:
        src: templates/myfile.json.j2
        dest: /home/{{ ansible_user }}/my-folder/myfile.json

j2 template file

templates/myfile.json.j2

{
  "value_one": "{{ my_value_one }}",
  "value_two": "{{ my_value_two }}",
}

Ansible Version: 2.16.7
Jinja: 3.1.4

I have tried the following:-

• Changing directory structure
• Playing with inventory, changes structure, using yaml file
• Using include vars task
