無法訪問Pod日志

Question

我正在嘗試訪問kubernetes集群中pod的日志，但是在發送以下休息請求時得到404消息：

GET api /命名空間/ myNamespace / pods / myPod / log

當我嘗試查看廣告連播的狀態時，我得到以下信息：

          }
        ]
      }
    },

為什么我無法查看日志？

Answer 1

這對我有效/ api / v1 / namespaces / myNamespace / pods / myPod / log

您的沒有api版本。

Answer 2

嘗試GET api / v1 / namespaces /“ podtest01734160-58f9-4042-8f38-3e55d7d5beb3” / pods / myPod / log

有兩點需要注意：1.在元數據中顯示“命名空間”：“ podtest01734160-58f9-4042-8f38-3e55d7d5beb3”，但不是myNamespace； 2。作為iocanel的答案，api版本是必需的，更多信息可以在這里查看： kubernetes.io/v1.1/docs/api-reference/v1/operations.html

Answer 3

我找到了這些； 當pod狀態更改為Running時，可以使用kubectl logs命令查看輸出。

kubectl logs podname
