创建一个动态列表，其中多个文件的内容都是元素

Question

我遇到一个问题，我需要读取目录的内容并创建一个列表，其中每个项目都是该目录中 yaml 文件的内容。

目录结构是这样的

/vars/
      abc.yml
      def.yml
      ...
      xyz.yml

各文件内容与此类似

---
manufacturer: F5
model: BIG-IP 3900
slug: big-ip-3900
part_number: '3900'
u_height: 1
is_full_depth: true

我的任务是这样的

---
- name: Include device types of .yaml files in directory into the 'device_types' variable
  include_vars:
    dir: vars/
    ignore_unknown_extensions: True
    extensions:
      - "yaml"
      - "yml"
    name: device_types

- name: Create NetBox Device Types
  netbox.netbox.netbox_device_type:
    netbox_token: "{{ netbox_token }}"
    netbox_url: "{{ netbox_url }}"
    validate_certs: False
    data:
      model: "{{ item.model }}"
      slug: "{{ item.slug }}"
      part_number: "{{ item.part_number }}"
      manufacturer: "{{ item.manufacturer | default(omit) }}"
      u_height: "{{ item.u_height | default(omit) }}"
      is_full_depth: "{{ item.is_full_depth | default(False)}}"
      subdevice_role: "{{ item.subdevice_role | default(omit) }}"
      comments: "{{ item.comments  | default(omit) }}"
    state: present
  loop: "{{ device_types }}"
  when: device_types is defined
  run_once: yes
  tags: netbox_device_types

但是，当我随后尝试遍历 device_types 变量时，它只是遍历每个文件内容的元素。我无法更改文件格式，因此我必须更改导入以使数据适合。

`fatal: [localhost]: FAILED! => {"msg": "Invalid data passed to 'loop', it requires a list, got this instead: {'manufacturer': 'Palo Alto', 'model': 'PA-850', 'slug': 'pa-850', 'part_number': 'PA-850', 'ight': 1, 'is_full_depth': False, 'interfaces': [{'name': 'management', 'type': '1000base-t', 'mgmt_only': True}, {'name': 'dedicated-ha1', 'type': '1000base-t'}, {'name': 'dedicated-ha2', 'type': '1000-t'}, {'name': 'loopback', 'type': 'virtual'}, {'name': 'ethernet1/1', 'type': '1000base-t'}, {'name': 'ethernet1/2', 'type': '1000base-t'}, {'name': 'ethernet1/3', 'type': '1000base-t'},..

给定最小化内容的文件进行测试

shell> tree test_vars
test_vars/
├── abc.yml
├── def.yml
└── xyz.yml

shell> cat test_vars/abc.yml 
---
manufacturer: F5
model: BIG-IP 3900

shell> cat test_vars/def.yml
---
manufacturer: F5
model: BIG-IP 3901

shell> cat test_vars/xyz.yml
---
manufacturer: F5
model: BIG-IP 3902

查找文件

    - find:
        paths: test_vars
        patterns: '*.yml,*.yaml'
      register: result

给予

  result.files|map(attribute='path')|list:
  - test_vars/xyz.yml
  - test_vars/abc.yml
  - test_vars/def.yml

然后创建包含一个文件并将项目添加到列表的任务的文件，例如

shell> cat include_device_type.yml
- include_vars:
    file: "{{ item }}"
    name: device_type
- set_fact:
    device_types: "{{ device_types|d([]) + [device_type] }}"

迭代文件并将数据包含在列表中

    - include_tasks: include_device_type.yml
      loop: "{{ result.files|map(attribute='path')|list }}"

给出设备类型列表

  device_types:
  - manufacturer: F5
    model: BIG-IP 3902
  - manufacturer: F5
    model: BIG-IP 3900
  - manufacturer: F5
    model: BIG-IP 3901

创建一个动态列表，其中多个文件的内容都是元素
