Question

我正在尝试访问kubernetes群集中的pod的日志，但在发送以下休息请求时获得404：

获取api / namespaces / myNamespace / pods / myPod / log

当我尝试查看pod的状态时，我得到以下信息：

          }
        ]
      }
    },

为什么我无法登录日志？

Answer 1

这适用于我/ api / v1 / namespaces / myNamespace / pods / myPod / log

你的没有api版本。

Answer 2

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

有两点需要注意： 1.在元数据中它显示“命名空间”：“podtest01734160-58f9-4042-8f38-3e55d7d5beb3”，但它不是myNamespace， 2.作为iocanel的答案，api版本是必要的，更多信息可以在这里查看： kubernetes.io/v1.1/docs/api-reference/v1/operations.html

Answer 3

我发现了这些; 当pod状态更改为Running时，您可以使用kubectl logs命令查看输出。

kubectl logs podname

https://github.com/kubernetes/kubernetes/blob/master/docs/getting-started-guides/logging.md

kubectl cluster-info

http://kubernetes.io/v1.0/docs/user-guide/accessing-the-cluster.html#accessing-the-api-from-a-pod How do I access the Kubernetes api from within a pod container?

无法访问pod日志
