elasticsearch - elasticsearch.yml的Ansible幂等

Question

新的ansible用户(v2.3)并为github拉取了剧本，但不了解幂等性。一旦安装了Elasticsearch并从Playbook开始，我现在希望能够修改或添加es_config参数，然后重新运行Playbook，期待已更新的elasticsearch.yml配置文件并重新启动elasticsearch。但是，该include_roles elasticsearch在重新运行时会被跳过，不确定是否要进行更改以进行更改。

include_role的格式问题。每个角色包含一个角色的已解决问题如下:

- include_role:
      name: java
- include_role:
      name: elasticsearch

等等。
