在 Ansible 中获取输出的特定部分

Question

我只需要从 Ansible 获取输出的特定部分，但它为我提供了全部信息。我试过使用过滤失败。

这是我正在测试的剧本（它有一个循环，可能是让我失望的原因）

- name: PLAYBOOK -> Testing
  hosts: esxi
  gather_facts: no
  vars_files:
    -  vars.yml
  vars:
    vmnic:
     - vmnic0
     - vmnic1

  tasks:
    -  name: Get NIC driver/firmware details - shell
       shell: esxcli network nic get -n {{ item }} | grep -e Driver -e Firmware -e Version -e Name
       loop: "{{ vmnic }}"
       register: nic_details

    -  name: Output NIC driver/firmware details
       debug:  var=item.stdout_lines
       loop: "{{ nic_details['results'] }}"

这是我为一台主机获得的输出，我只需要最后一位，即 Driver Info、Driver、Firmware Version、Version 和“每个主机的名称” VMNIC.

Answer 1

您可以使用 map filter to extract one field of a list of dictionaries. It can also be used to map one filter to each items of the list, for example, a from_yaml 来帮助您从 stdout 中获得的字符串中提取字典。

鉴于任务：

- debug:
    var: nic_details.results | map(attribute="stdout") | map('from_yaml')

这将导致：

nic_details.results | map(attribute="stdout") | map('from_yaml'):
- Driver Info:
    Driver: igbn
    Firmware Version: 1.61.0:0x8000090e
    Version: 1.4.1
  Name: vmnic0
- Driver Info:
    Driver: igbn
    Firmware Version: 1.61.0:0x8000090e
    Version: 1.4.1
  Name: vmnic1
