将ansible响应转换为yaml格式

Question

我正在尝试将设备的响应转换为 yaml 格式。我尝试使用with_together，似乎它是我能得到的最接近所需的输出。我还尝试使用 Jinja2 模板，但在将响应中的数据解析为 Jinja2 时遇到问题。似乎我缺少另一个循环来迭代前缀。

任务：

- name: Gather Junos prefix-lists
  junipernetworks.junos.junos_prefix_lists:
    state: gathered
  register: prefix_response

- name: parse info
  set_fact:
    prefix_name: "{{ prefix_response | to_json | from_json | json_query(prefix_name_query) }}"
    prefix: "{{ prefix_response | to_json | from_json | json_query(prefix_query) }}"
  vars:
    prefix_name_query: 'gathered[].name'
    prefix_query: 'gathered[]."address_prefixes"'

- name: Write to file
  ansible.builtin.lineinfile:
    path: "output.yaml"
    state: present
    line: |
      - prefix_list_name: {{ item.0 }}
        prefix:
          - {{ item.1 }}
  with_together:
    - "{{ prefix_name }}"
    - "{{ prefix }}"

前缀_响应：

[
        {
            "address_prefixes": [
                "10.0.0.0/8",
                "172.16.0.0/12",
                "192.168.0.0/16"
            ],
            "name": "test1"
        },
        {
            "address_prefixes": [
                "1.1.1.1/32",
                "2.2.2.2/32",
                "3.3.3.3/32"
            ],
            "name": "test2"
        }
]

当前回报：

- prefix_list_name: RFC_1918
  prefix:
    - 10.0.0.0/8
- prefix_list_name: test2
  prefix:
    - 1.1.1.1/32

期望回报：

- prefix_list_name: TEST1
  prefix:
    - 10.0.0.0/8
    - 172.16.0.0/12
    - 192.168.0.0/16

- prefix_list_name: TEST2
  prefix:
    - 1.1.1.1/32
    - 2.2.2.2/32
    - 3.3.3.3/32

Answer 1

创建一个字典并在下面的模板中使用它

    - template:
        src: output.yaml.j2
        dest: output.yaml
      vars:
        prefix_response_dict: "{{ prefix_response.gathered|
                                  items2dict(key_name='name',
                                             value_name='address_prefixes') }}"

shell> cat output.yaml.j2
{% for k,v in prefix_response_dict.items() %}
- prefix_list_name: {{ k|upper }}
  prefix:
    {{ v|to_nice_yaml|indent(4) }}
{%- endfor %}

给出

shell> cat output.yaml
- prefix_list_name: TEST1
  prefix:
    - 10.0.0.0/8
    - 172.16.0.0/12
    - 192.168.0.0/16
- prefix_list_name: TEST2
  prefix:
    - 1.1.1.1/32
    - 2.2.2.2/32
    - 3.3.3.3/32

如果要创建结构，请先将名称转换为大写

prefix_response_keys: "{{ prefix_response.gathered|
                          map(attribute='name')|
                          map('upper')|
                          map('community.general.dict_kv', 'name')|list }}"

给出

prefix_response_keys:
  - name: TEST1
  - name: TEST2

然后，更新列表中的属性名称

prefix_response_uppr: "{{ prefix_response.gathered|
                          zip(prefix_response_keys)|
                          map('combine')|list }}"

给出

prefix_response_uppr:
  - address_prefixes:
    - 10.0.0.0/8
    - 172.16.0.0/12
    - 192.168.0.0/16
    name: TEST1
  - address_prefixes:
    - 1.1.1.1/32
    - 2.2.2.2/32
    - 3.3.3.3/32
    name: TEST2

您想要的预期结果是上面的列表，其中属性名称已更改。只有两个属性（name和address_prefixes），因此，让我们将其转换为字典

prefix_response_dict: "{{ prefix_response_uppr|
                          items2dict(key_name='name',
                                     value_name='address_prefixes') }}"

给出

prefix_response_dict:
  TEST1:
    - 10.0.0.0/8
    - 172.16.0.0/12
    - 192.168.0.0/16
  TEST2:
    - 1.1.1.1/32
    - 2.2.2.2/32
    - 3.3.3.3/32

然后，我们将其转换回列表并更改属性的名称

prefix_response_list: "{{ prefix_response_dict|
                          dict2items(key_name='prefix_list_name',
                                     value_name='prefix') }}"

给出

prefix_response_list:
  - prefix:
    - 10.0.0.0/8
    - 172.16.0.0/12
    - 192.168.0.0/16
    prefix_list_name: TEST1
  - prefix:
    - 1.1.1.1/32
    - 2.2.2.2/32
    - 3.3.3.3/32
    prefix_list_name: TEST2

现在，将其写入文件。使用过滤器to_nice_yaml格式化 YAML 输出

shell> cat output.yaml.j2
{{ prefix_response_list|to_nice_yaml }}

适当地放置变量的声明。例如下面的任务

    - template:
        src: output.yaml.j2
        dest: output.yaml
      vars:
        prefix_response_keys: "{{ prefix_response.gathered|
                                  map(attribute='name')|
                                  map('upper')|
                                  map('community.general.dict_kv', 'name')|list }}"
        prefix_response_uppr: "{{ prefix_response.gathered|
                                  zip(prefix_response_keys)|
                                  map('combine')|list }}"
        prefix_response_dict: "{{ prefix_response_uppr|
                                  items2dict(key_name='name',
                                             value_name='address_prefixes') }}"
        prefix_response_list: "{{ prefix_response_dict|
                                  dict2items(key_name='prefix_list_name',
                                             value_name='prefix') }}"

将创建文件

shell> cat output.yaml
-   prefix:
    - 10.0.0.0/8
    - 172.16.0.0/12
    - 192.168.0.0/16
    prefix_list_name: TEST1
-   prefix:
    - 1.1.1.1/32
    - 2.2.2.2/32
    - 3.3.3.3/32
    prefix_list_name: TEST2
