Question

我通过kubeadm设置kubernetes集群，pod网络是法兰绒，我可以获取在主服务器上运行的pod的日志。

$ kubectl get pod -o wide
NAME                     READY     STATUS    RESTARTS   AGE       IP            NODE
httpd-7448fc6b46-fgkp2   1/1       Running   0          1d        10.244.2.39   k8s-node2
httpd-7448fc6b46-njbh8   1/1       Running   0          1d        10.244.0.10   k8smaster
httpd-7448fc6b46-wq4zs   1/1       Running   0          1d        10.244.1.75   k8s-node1

$ kubectl logs httpd-7448fc6b46-njbh8

10.244.0.1 - - [21/Mar/2018:10:22:53 +0000] "GET / HTTP/1.1" 200 45

但我无法获取在从属节点上运行的pod的日志，结果如下：

"Error from server: Get https://192.168.18.111:10250/containerLogs/default/httpd-7448fc6b46-6pf7w/httpd?follow=true: cannotconnect"

如何调试问题？任何想法？

问题已经解决，我的群集在防火墙后面，需要设置代理才能下载映像，所以我设置了docker的代理，但是当我设置时我没有绕过从节点代理，因此日志请求被docker中的代理设置误导。

无法获取kubernetes＆＃39;从节点
