使用jq解析AWS CLI工具的json輸出

我想使用jq（http://stedolan.github.io/jq/）解析aws ec2 describe-instances的json輸出，並僅在標籤包含Name的情況下返回實例ID和標籤。所有者，成本中心。使用jq解析AWS CLI工具的json輸出

這裏是代表源輸出部分節錄JSON：

我使用這個命令：

aws ec2 describe-instances | jq '.Instances[] | select(.Tags==["Name","Owner","cost.centre") | .InstanceId, .Tags'

但它給我的錯誤：

              ^
    error: Invalid character 
.Reservations[].Instances | map(select(has("Tags"))) |.Tags[].Key=="cost.centre")) | map(select(has("InstanceId"))) | .[].InstanceId,.[].Tags 
                       ^
error: Invalid character 
.Reservations[].Instances | map(select(has("Tags"))) |.Tags[].Key=="cost.centre")) | map(select(has("InstanceId"))) | .[].InstanceId,.[].Tags 
                       ^
2 compile errors 

[Errno 32] Broken pipe

請幫我解決這個錯誤

主要問題是您的查詢缺少關閉']'，但是我認爲對具有這些標記的EC2實例進行過濾有點麻煩。

這可能是有點令人費解，但這樣的事情對我的作品：

aws ec2 describe-instances | jq '.Instances | map(select(has("Tags"))) | map(select(.Tags[].Key=="Name" and .Tags[].Key=="Owner" and .Tags[].Key=="Cost.centre")) | map(select(has("InstanceId"))) | .[].InstanceId,.[].Tags'

此命令正在返回沒有輸出 –

對不起，我的aws命令有一個「預訂」頂級元素，而「cost.centre」應該是en Cost.centre「。我更新了命令以匹配您提供的JSON。 – sorohan

你能否爲大小寫敏感嗎？ – user3086014

試試這個：

$ aws ec2 describe-instances --output json | jq '.Reservations[].Instances[] | (.Tags | from_entries) as $tags | select($tags.Owner != null) | {InstanceID: .InstanceId, Name: $tags.Name, Owner: $tags.Owner, CostCenter: $tags."cost.center"}'

...返回：

{ 
    "InstanceID": "i-734cbc51", 
    "Name": "someserver001", 
    "Owner": "[email protected]", 
    "CostCenter": "ABC001" 
}

這對當前aws ec2 describe-instances的輸出有效，但我只注意到它需要調整您的示例輸入;這適用於你的示例：cat sample | jq'.Instances [] | （.Tags | from_entries）作爲$ tags |選擇（$ tags.Owner！= null）| {InstanceID：.InstanceId，名稱：$ tags.Name，所有者：$ tags.Owner，CostCenter：$ tags。「Cost.centre」}' – phatypus
