问题描述
我从设置模块收到了以下数据:
ansible_nodename: 3d734bc2a391,
ansible_os_family: RedHat,
ansible_pkg_mgr: yum,
ansible_processor:[
AuthenticAMD,
AMD PRO A10-8700B R6,10计算核心4C + 6G
],
ansible_processor_cores:1,
ansible_processor_count:1,
ansible_processor_threads_per_core:1,
$ c $我想检索 ansible_processor
的第一个值,并在Jinja2模板中使用它。
如果我使用 {{ansible_processor}}
,它会给我两个值:
AuthenticAMD,
AMD PRO A10-8700B R6,10个计算内核4C + 6G
但是我只想要第一个。
解决方案要获取列表中的第一项:
-调试:
msg:第一项:{{ansible_processor [0]}}
或:
-调试:
msg:第一个项目:{{ansible_processor | first}}
I received the following data from the setup module:
"ansible_nodename": "3d734bc2a391",
"ansible_os_family": "RedHat",
"ansible_pkg_mgr": "yum",
"ansible_processor": [
"AuthenticAMD",
"AMD PRO A10-8700B R6, 10 Compute Cores 4C+6G"
],
"ansible_processor_cores": 1,
"ansible_processor_count": 1,
"ansible_processor_threads_per_core": 1,
I want to retrieve the 1st value of ansible_processor
and use it in a Jinja2 template.
If I use {{ ansible_processor }}
, it's giving me both values:
"AuthenticAMD",
"AMD PRO A10-8700B R6, 10 Compute Cores 4C+6G"
But I want only the first one.
解决方案 To get first item of the list:
- debug:
msg: "First item: {{ ansible_processor[0] }}"
Or:
- debug:
msg: "First item: {{ ansible_processor | first }}"
