如何插入匹配JSON鍵的值JSON文件，我有2間2

一個模板JSON
一個JSON輸出（從awscli）

模板是下面小JSON文件：

{ 
 
    "DryRun": true, 
 
    "ImageId": "", 
 
    "KeyName": "", 
 
    "SecurityGroups": [ 
 
    "" 
 
    ], 
 
    "InstanceType": "", 
 
    "Monitoring": { 
 
    "Enabled": false 
 
    }, 
 
    "SubnetId": "", 
 
    "DisableApiTermination": true, 
 
    "PrivateIpAddress": "", 
 
    "IamInstanceProfile": { 
 
    "Arn": "", 
 
    "Name": "" 
 
    }, 
 
    "EbsOptimized": true, 
 
    "TagSpecifications": [{ 
 
    "ResourceType": "", 
 
    "Tags": [{ 
 
     "Key": "", 
 
     "Value": "" 
 
    }] 
 
    }] 
 
}

原始文件的aws ec2 describe-instances輸出：

     } 
 
     ], 
 
     "AmiLaunchIndex": 0 
 
    }] 
 
    }] 
 
}

我想鍵的值複製在原來的JSON文件的模板文件。

例如，KeyName是2個JSON文件之間的常用鍵。在模板文件中替換相應的值tempKey。

這樣做的主要用例是：我試圖將AWS上的多個服務器從一個區域遷移到另一個區域。這是遷移過程的一部分，它將刪除AWS Console上的大量手動點擊和配置。

注意：我使用BASH命令行。

有一種方法可以與jq做到這一點，但它不會將JSON模板作爲輸入。

您必須修改它才能成爲查詢。這不是你所需要的實際查詢，但一些讓你開始：

cat temp.json | jq '.Reservations[].Instances[] | { DryRun, ImageId, KeyName, SecurityGroups, InstanceType, Monitoring }'

哪裏temp.json就是上面那個我放到一個文件你的輸出。對於常規的命令，只是像做aws ec2 describe-instances | jq ...

，讓我（記住限制集合我查詢了）的輸出是：

{ 
    "DryRun": null, 
    "ImageId": "ami-1234abcd", 
    "KeyName": "tempKey", 
    "SecurityGroups": [ 
    { 
     "GroupName": "somegroup1", 
     "GroupId": "sg-ZZZZZ" 
    }, 
    { 
     "GroupName": "somegroup2", 
     "GroupId": "sg-YYYYY" 
    } 
    ], 
    "InstanceType": "t2.medium", 
    "Monitoring": { 
    "State": "disabled" 
    } 
}

希望這有助於。

此外，我發現這有更多的食譜來處理'describe-instances'輸出和'jq'：http://stackoverflow.com/questions/30601278/how-to-extract-keys-from-multiple -nested-arrays-using-jq – Mutahhir

謝謝。會做一些修補和更新你。 – kintuparantu
