将新项目添加到 Ansible 中的列表

Question

我有一个数组

  a1:
    - channelId: test1
    - channelId: test2

我正在尝试向数组添加新的密钥对值

  a2:
    - channelId: test1
    - channelId: test2
    - channelId: test3

Ansible Playbook：我尝试将新键值对添加到现有 JSON 数组的部分代码

- name: Setting Channel id
  set_fact:
    channelarray: "{{ newrelic_alertpolicyresult | json_query('json.data.actor.account.aiWorkflows.workflows.entities[*].destinationConfigurations[*]')}}"
    workflowid: "{{ newrelic_alertpolicyresult | json_query('json.data.actor.account.aiWorkflows.workflows.entities[*].id') }}"
    
- name: PrintChannel ID
  debug:
    msg: "Channel ID - {{ channelarray }}  &  Workflow ID - {{ workflowid }}"
    
- name: PrintChannel ID in loop
  debug:
    msg: "{{ item }}"
  loop: "{{ channelarray }}"

- name: Convert JSON to dictionary
  set_fact: 
    updated_channel_array: "{{ channelarray + [{ 'channelId': 'test3' }] | json_query('[*]')  }}"

  
- name: Print updated channel array
  debug:
     msg: "{{ updated_channel_array }}"

输出：

TASK [Setting Channel id] 
ok: [localhost]

TASK [PrintChannel ID] 
ok: [localhost] => {
    "msg": "Channel ID - [[{'channelId': 'f35ead0f-8252-4975-9055-5d050161da01'}, {'channelId': 'be33c326-08d4-494c-b544-6c86beb0dd5e'}]]  &  Workflow ID - ['d7d1db30-918e-4202-a7ba-1613cf9600a1']"
}

        }
    ]
}

            {
                "channelId": "be33c326-08d4-494c-b544-6c86beb0dd5e"

        ],
        {
            "channelId": "test3"
        }
    ]
}

最后一个密钥对值应添加到destinationConfigurations数组中

Answer 1

下面的表情

  a2: "{{ a1 + [{ 'channelId': 'test3' }] }}"

给你想要的

  a2:
  - channelId: test1
  - channelId: test2
  - channelId: test3

如果您出于某种原因必须使用set_fact，下面的任务会给出相同的结果

    - set_fact:
        a2: "{{ a1 + [{ 'channelId': 'test3' }] }}"

用于测试的完整剧本示例

- hosts: localhost

  vars:

    a1:
      - channelId: test1
      - channelId: test2

    a2: "{{ a1 + [{ 'channelId': 'test3' }] }}"

  tasks:

    - debug:
        var: a2

    - set_fact:
        a3: "{{ a1 + [{ 'channelId': 'test3' }] }}"
    - debug:
        var: a3
