【问题描述】:
我正在尝试从我的 pod 中获取日志,但由于某种原因它不起作用,尽管 kubectl describe pod 运行良好,docker logs 运行良好。我在单个节点上手动安装了 Kubernetes 1.2.3 Debian 8 x64
$ kubectl logs -f web-backend-alzc1 --namespace=my-namespace --v=6
round_trippers.go:286] GET http://localhost:8080/api 200 OK in 0 milliseconds

round_trippers.go:286] GET http://localhost:8080/api/v1/namespaces/my-namespace/pods/web-backend-alzc1/log?follow=true 404 Not Found in 1 milliseconds
helpers.go:172] server response object: [{
"metadata": {},
"status": "Failure",
"message": "the server could not find the requested resource ( pods/log web-backend-alzc1)",
"reason": "NotFound",
"details": {
"name": "web-backend-alzc1",
"kind": "pods/log"
},
"code": 404
}]
helpers.go:107] Error from server: the server could not find the requested resource ( pods/log web-backend-alzc1)
我应该在 RC 方案中描述一些内容以启用此 pod 的日志吗?
我尝试重新创建 RC 并查看 journalctl,我看到这些消息:
hyperkube[443]: I0510 12:14:13.754922 443 hairpin.go:51] Unable to find pair interface, setting up all interfaces: exec: "ethtool": executable file not found in $PATH

【问题讨论】:
-
你是如何启动你的节点的?具体来说,您是否将
--enable-debugging-handlers标志设置为 false? -
这是一个普通的EC2节点,我下载了hyperkube和kubectl的二进制文件,通过systemd启动了kubelet、proxy、controller、scheduler和apiserver。这个解决方案已经在不同的机器上运行了几个月,只是我以前从未尝试过记录
-
对不起,我的意思是你用什么命令来启动 kubelet? (您是否禁用了
--enable-debugging-handlers标志?) -
哇!我已经在没有这个标志的情况下重新启动了 kubelet,它现在可以工作了!谢谢!
