How to use variables set in inventory file for the hostname /group

Hello

I have this inventory file:

/etc/ansible/inventory/inventory-file

`
[my-group]
myhost.com project=my group=group

[my-group:vars]
project=my
group=my-group

`

and this is my playbook

`

  • hosts: ‘{{ host }}’
    gather_facts: yes

roles:

  • role: collectd
    vars:
    group: {{ project }}
    project: {{ group }}

`

But for some reason ansible cant read those variables, can i know how i can access this variables ?

`

{% if project == “my” %}
<Node “my_graphite”>
Host “my_host”
{% elif project == “11” or project == “22” %}
<Node “11”>
Host “22”

`

I will be using this variables to create a flexible tempalte file
