Question

我正在尝试使用ansible hcloud模块。我需要使用创建的服务器的IP设置事实列表。

第一个服务器很容易，因为它总是一个：

创建空列表：

    - set_fact:
        ips: []

然后创建服务器，并将服务器IP添加到列表中：

    - set_fact:
        ips:
          - "{{ ips + [ a3srv_fact.hcloud_server.ipv4_address ] }}"

下一个块带有循环，因此寄存器给了我这个

"hc_fact": {
    "changed": false,
    "msg": "All items completed",
    "results": [
        {
            "ansible_loop_var": "item",
            "changed": false,
            "failed": false,
            "hcloud_server": {
                "backup_window": "None",

            },
            "item": "hc1"
        },
        {
            "ansible_loop_var": "item",
            "changed": false,
            "failed": false,

                    "volumes": null
                }
            },
            "item": "hc2"
        }
    ]
}

结果块可以包含1个或多个部分，有2个部分。

我需要将每个ipv4_address添加到现有的事实列表中。

我很确定yml语法有一种直接的方法，但是我无法理解。

Answer 1

使用json_query。下面的任务

- set_fact:
    ips: "{{ ips|default([]) +
             hc_fact.results|
             json_query('[*].hcloud_server.ipv4_address')
             }}"

给予

"ips": [
    "116.203.204.49", 
    "116.203.204.136"
]

ansible hcloud set_fact从字典列表中添加项目
