This *can't* set the fact in the hostname fake_host just fine if the host
in not valid. The play

- hosts: all
tasks:
- set_fact:
dummy_fact: "Hello world"
cacheable: yes
delegate_to: fake_host
delegate_facts: true
run_once: true
- debug:
var: hostvars.fake_host.ansible_facts
run_once: true


should report

"hostvars.fake_host.ansible_facts": "VARIABLE IS NOT DEFINED!"

If the host is valid. All works as expected. For example, the playbook

- hosts: all
tasks:
- set_fact:
dummy_fact: "Hello world"
cacheable: yes
delegate_to: test_01
delegate_facts: true
run_once: true
- debug:
var: hostvars.test_01.ansible_facts
run_once: true

- hosts: test_01
tasks:
- debug:
var: hostvars.test_01.ansible_facts
- meta: clear_facts
- debug:
var: hostvars.test_01.ansible_facts

gives

PLAY [all]
ok: [test_01] => {
"hostvars.test_01.ansible_facts": {
"dummy_fact": "Hello world"
}
}

PLAY [test_01]
ok: [test_01] => {
"hostvars.test_01.ansible_facts": {
"dummy_fact": "Hello world"
}
}
ok: [test_01] => {
"hostvars.test_01.ansible_facts": {}
}

To make it reproducible test it without tower. HTH,

This list is for Ansible and not Tower, please contact RedHat for
