Ansible Dynami c инвентарь в формате JSON не анализируется

Я попытался написать сценарий инвентаризации Dynami c в python, который выглядит следующим образом: 

[root@satellite code]# python3 dynamic_inventory.py --list > hosts
[root@satellite code]# cat hosts
{"k8s-master": ["k8s-master.example.com"], "k8s-worker": ["worker-1.example.com", "worker-2.example.com"], "satellite": ["satellite.example.com"], "all": ["satellite.example.com", "worker-2.example.com", "k8s-master.example.com", "worker-1.example.com"], "Centos7": ["k8s-master.example.com", "worker-1.example.com", "worker-2.example.com", "satellite.example.com"]}

Теперь, когда я пытаюсь использовать инвентарь, я получаю следующие ошибки: 

[root@satellite code]# ansible-playbook -i hosts sample.yaml

Тоже пробовал: 

[root@satellite code]# ansible-playbook -i dynamic_inventory.py sample.yaml
[WARNING]:  * Failed to parse /root/code/dynamic_inventory.py with ini plugin: /root/code/dynamic_inventory.py:1: Expected key=value host variable assignment, got: os

Скрипт извлекает имена хостов из MySQL DB в формат JSON. Я не нашел никаких плагинов в официальных документах ansible. Может ли кто-нибудь помочь, как go об этом? Есть ли способ отобразить вывод скрипта в формате ini.

Я попытался изменить скрипт на исполняемый и получил следующее: 

[root@satellite code]# ansible-playbook -i dynamic_inventory.py sample.yaml
[WARNING]:  * Failed to parse /root/code/dynamic_inventory.py with script plugin: problem running /root/code/dynamic_inventory.py --list ([Errno 8] Exec format error)
[WARNING]:  * Failed to parse /root/code/dynamic_inventory.py with ini plugin: /root/code/dynamic_inventory.py:1: Expected key=value host variable assignment, got: os

Обратите внимание, что на этот раз он использовал плагин скрипта, «Ошибка формата Exe c» возникла из-за того, что моя система по умолчанию установила python2. Добавил шебанг (#! / Usr / bin / python3) в файл, и он сработал: 

[root@satellite code]# ansible-playbook -i dynamic_inventory.py sample.yaml
