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

问题描述

我在Ansible中注册了名为网络"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"
            }
        ]
    }
}

是否可以像这样使用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" }}

我知道语法错误，但是您明白了.

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

推荐答案

我已经提交了拉请求(在Ansible 2.2+中可用)，通过在以下位置添加 jmespath 查询支持，可以简化这种情况太好了在您的情况下，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\") }}"

将返回:

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