aws-cli - AWS CLI 查询 IF 条件

问题描述

我可以获得有关在 cli 表输出中获取别名记录的值的帮助吗？

test.emea.example.com。是别名。

顺便说一句，如果 DNS 记录是多值的，如何扁平化和连接值

下面是示例：

 $ aws route53 list-resource-record-sets --hosted-zone-id Z34XXXXXXXX4EF --query "ResourceRecordSets[?Type=='A']"
[
    {
        "ResourceRecords": [
            {
                "Value": "10.189.134.12"
            }
        ], 
        "Type": "A", 
        "Name": "dnsforwarder0.emea.example.com.", 
        "TTL": 300
    }, 
    {
        "ResourceRecords": [
            {
                "Value": "10.189.134.47"
            }
        ], 
        "Type": "A", 
        "Name": "dnsforwarder1.emea.example.com.", 
        "TTL": 300
    }, 
    {
        "ResourceRecords": [
            {
                "Value": "10.189.134.78"
            }
        ], 
        "Type": "A", 
        "Name": "dnsforwarder2.emea.example.com.", 
        "TTL": 300
    }, 
    {
        "AliasTarget": {
            "HostedZoneId": "Z32O12XQLNTSW2", 
            "EvaluateTargetHealth": false, 
            "DNSName": "dualstack.kubernetes-elb-k8fca-prod-emea-1745420721.eu-west-1.elb.amazonaws.com."
        }, 
        "Type": "A", 
        "Name": "test.emea.example.com."
    }
]

解决方案

基于 John 和 Alex 的想法，我使用 union 以及 join 函数来获得我想要的东西。但是，它太冗长了。

$ aws route53 list-resource-record-sets --hosted-zone-id Z34XXXXXXXX4EF --query "[ResourceRecordSets[?Type=='A' && contains(keys(@), 'AliasTarget')].[Name,Type,AliasTarget.DNSName],ResourceRecordSets[?Type=='A' && contains(keys(@), 'ResourceRecords')].[Name,Type,join(', ', ResourceRecords[].Value)]]" --output table
