Ansible tower behind nginx

On the official page, it is said that to host ansible tower behind nginx, you need to provide headers in the /etc/tower/conf.d/remote_host_headers.py file.

But, in my /etc/tower/ folder, there is no conf.d/remote_host_headers.py file.

awx@server:/etc/tower$ tree
.
├── conf.d
│ ├── caching.py
│ ├── celeryd.py
│ ├── ha.py
│ ├── postgres.py
│ └── rabbitmq.py
├── SECRET_KEY
├── settings.py
├── settings.py.20170629122404
├── tower.cert
└── tower.key

How can I host ansible tower via nginx ?

An uneducated guess: did you try to create the missing file?

Okay, and can you help me with that what to do in nginx file ?
