Using IP address instead of hostname in Ansible AWX/Tower #question

[silverbullet0201]

Current situation:
I use ansible tower (a.k.a. AWX) to manage our infrastructure
Names of our hosts are human-readable names like pg-node-01, pg-node-02, ...

When I run deploy_pgcluster.yaml playbook it fails in Enable and start etcd service task because in the etcd settings like ETCD_LISTEN_CLIENT_URLS and ETCD_ADVERTISE_CLIENT_URLS hostname (value from inventory_hostname) is used instead of host's IP address

---

My question is next:
Can we make playbook roles to use IP-address of the hostname (from ansible_host variable from inventory for example) instead of inventory hostname (inventory_hostname variable is in use currently)

Maybe there's option like adding variable ansible_host to inventory and replacing {{ inventory_hostname }} to {{ ansible_host | default(inventory_hostname) }} in ./roles/etcd/templates/etcd.conf.j2 (or in any other place that required)

---

There's some example:
IP-address is used instead of hostname (etcd service is running and working)

ETCD_LISTEN_CLIENT_URLS="http://1.2.3.4:2379,http://127.0.0.1:2379"
ETCD_ADVERTISE_CLIENT_URLS="http://1.2.3.4:2379"
# ...

hostname is used instead of IP-address (etcd service is stopping just after start)

ETCD_LISTEN_CLIENT_URLS="http://pg-node-01:2379,http://127.0.0.1:2379"
ETCD_ADVERTISE_CLIENT_URLS="http://pg-node-01:2379"
# ...

Yes, it must be done. It is not the first request on the topic inventory_hostname.

Currently, it is required to specify IP addresses.
