如何追加特定数据到JSON数组

3

我正在尝试运行：

- name: Describe config aggregator
  shell: >
    aws configservice describe-configuration-aggregators --configuration-aggregator-name test-config
  register: config_ouput

以下是生成的数据。

    {
        "ConfigurationAggregators": [
            {
                "ConfigurationAggregatorName": "test-config",
                "ConfigurationAggregatorArn": "arn:aws:config:us-east-1:4567:config-aggregator/config-aggregator-uw2o9pzf",
                "AccountAggregationSources": [
                    {
                        "AccountIds": [
                            "895677"
                        ],
                        "AllAwsRegions": true
                    }
                ],
                "CreationTime": 1624454176.124,
                "LastUpdatedTime": 1626426755.504
            }
        ]
    }

现在我想要将上面的账户ID与任何新的账户（例如1234567）连接起来，得到以下结果：

{
    "ConfigurationAggregators": [
        {
            "ConfigurationAggregatorName": "test-config",
            "ConfigurationAggregatorArn": "arn:aws:config:us-east-1:8778:config-aggregator/test-config-pzf",
            "AccountAggregationSources": [
                {
                    "AccountIds": [
                        "895677,1234567"
                    ],
                    "AllAwsRegions": true
                }
            ],
            "CreationTime": 1624454176.124,
            "LastUpdatedTime": 1626426755.504
        }
    ]
}

我想要做的是：

- name: Export results to JSON
  set_fact:
    config_ouput_json: "{{ config_ouput + [{"AccountIds": "1234567","AllAwsRegions": true}]}}"

但这个不起作用，请告诉我正确的语法。

基本上，您需要进行一些JSON操作来完成您的任务。

步骤：

1. 将第一个命令的输出存储在某个json文件中。在您的情况下，您可以将其保留为ansible的注册变量。 2. 获取现有的account_ids并存储在某个变量中。 3. 在ansible中创建一个新帐户的列表作为变量。 4. 遍历新的account_ids并添加到现有的account_ids中。 5. 更新aws config命令。

示例代码：

- name: initial validation
  hosts: localhost
  connection: local
  vars:
    newAccountIds:
      - "123456"
      - "566544"
      - "555445"

  tasks:
  - name: register json file
    include_vars:
      file: 'abc.json'
      name: bundle

  - name: set value
    set_fact:
      values: "{{ bundle['ConfigurationAggregators'][0]['AccountAggregationSources'][0]['AccountIds'] }}"

  - set_fact:
      values: "{{ (values | default([])) + [item] }}"
    with_items: "{{ newAccountIds }}"

  - debug:
      msg: "{{ values }}"

  - debug:
      msg: '"aws configservice put-configuration-aggregator --configuration-aggregator-name test-config --account-aggregation-sources "[{"AccountIds": {{ values | to_json }},"AwsRegions": ["us-east-1"]}]\""'

示例输出：
