Я пытаюсь использовать фильтр ниже, чтобы получить значение Endpoint: stdout_lines.DBCluster.Endpoint

Answer 1

Ваш результат - объект json, который необходимо пропустить через фильтр from_ json. Простой тест:

- hosts: masters
  gather_facts: false
  tasks:
  - shell: /root/ansible/test.sh
    register: result
  - debug:
      msg: "{{ (result.stdout | from_json).DBCluster.Endpoint }}"

Тестовые данные:

#!/bin/bash
echo '{'
echo '"DBCluster": {'
echo '"Endpoint": "value1"'
echo '}, "key2": "value2"'
echo '}'
