How to reference host variable in Ansible template?

I have the following Ansible project structure:

├── demo.yml
├── hosts
├── group_vars
│   └── all
└── roles
    ├── common
    │   ├── tasks
    │   │   └── main.yml
    │   └── templates
    │       └── init.j2

Inside 'hosts', I have:

[primary]
server1
[secondary]
server2

In roles/common/templates/init.j2, I want to be able to refer to the [primary] group variable. Since Ansible uses Jinja2 for its template module. I was directed to this Jinja2 doc.

I tried:

print("{{ group['primary'] }}")

But it will return:

['server1']

Right now I can only get it within a loop:

{% for host in groups['primary'] %}
    print("{{ host }}")
{% endfor %}

It will return what I want:

server1

But how do I get this result without using a loop?

Try this...

groups['primary'][0]

or just print group and you should be able to see how the data is store.

Hope this helps!
