如何从 Ansible 中设置模块的输出中获取列表的第一个元素? [英] How to get the first element of a list from the output of setup module in Ansible?

问题描述

我从设置模块收到以下数据:

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,

我想检索 ansible_processor 的第一个值并在 Jinja2 模板中使用它.

I want to retrieve the 1st value of ansible_processor and use it in a Jinja2 template.

如果我使用 {{ ansible_processor }}，它会给我两个值:

If I use {{ ansible_processor }}, it's giving me both values:

"AuthenticAMD",
"AMD PRO A10-8700B R6, 10 Compute Cores 4C+6G"

但我只想要第一个.

推荐答案

获取列表的第一项:

- debug:
    msg: "First item: {{ ansible_processor[0] }}"

或者:

- debug:
    msg: "First item: {{ ansible_processor | first }}"
