      } 
     ] 
     } 
    } 
    ] 
} 

的事情，我知道：

"secretName": "klucze"  

的事情，我想提取

"name": "provisioner-secrets-1750468340-ei8sl"  

我試過

.items[] | .spec | .volumes[] | .secret | select(.secretName=="klucze")  

，但我不知道如何從

.items[] | .metadata | .name  

得到相關值請建議我怎麼能解決這個問題

Answer 1

你知道如何讓你正在尋找相應的名稱，只是在那裏添加一個select您需要的條件。幸運的是，您的狀況涉及您正在搜索的項目，而不是另一個不相關的對象。

$ jq --arg secret 'klucze' \ 
'.items[] | select(.spec.volumes[].secret.secretName == $secret).metadata.name' input.json
