Ansible:按属性过滤列表 [英] Ansible: filter a list by its attributes

问题描述

我在 Ansible 中注册了名为network"的变量:

I have variable named "network" registered in Ansible:

{
    "addresses": {
        "private_ext": [
            {
                "type": "fixed",
                "addr": "172.16.2.100"
            }
        ],
        "private_man": [
            {
                "type": "fixed",
                "addr": "172.16.1.100"
            },
            {
                "type": "floating",
                "addr": "10.90.80.10"
            }
        ]
    }
}

是否可以通过 type="floating" 来获取 IP 地址(addr")?

Is it possible to get the IP address ("addr") with type="floating" doing something like this?

- debug: var={{ network.addresses.private_man | filter type="fixed" | get "addr" }}

我知道语法有误，但你懂的.

I know the syntax is wrong but you get the idea.

推荐答案

我已经提交了一个pull请求(在 Ansible 2.2+ 中可用)通过在能干.在您的情况下，它的工作方式如下:

I've submitted a pull request (available in Ansible 2.2+) that will make this kinds of situations easier by adding jmespath query support on Ansible. In your case it would work like:

- debug: msg="{{ addresses | json_query(\"private_man[?type=='fixed'].addr\") }}"

会回来:

ok: [localhost] => {
    "msg": [
        "172.16.1.100"
    ]
}
