来自服务器的错误：获取 pod 日志时拨打 tcp i/o 超时错误

Question

我正在开发 OpenShift Origin 1.1（它使用 kubernetes 作为 docker 容器的编排工具）。我正在创建 pod，但我看不到构建日志。

[user@ip master]# oc get pods
NAME           READY     STATUS      RESTARTS   AGE
test-1-build   0/1       Completed   0          14m
test-1-iok8n   1/1       Running     0          12m
[user@ip master]# oc logs test-1-iok8n
Error from server: Get https://ip-10-0-x-x.compute.internal:10250/containerLogs/test/test-1-iok8n/test: dial tcp 10.0.x.x:10250: i/o timeout

我的/var/logs/messages 显示：

Dec  4 13:28:24 ip-10-0-x-x origin-master: E1204 13:28:24.579794   32518 apiserver.go:440] apiserver was unable to write a JSON response: Get https://ip-10-0-x-x.compute.internal:10250/containerLogs/test/test-1-iok8n/test: dial tcp 10.0.x.x:10250: i/o timeout

我的版本是：

origin v1.1.0.1-1-g2c6ff4b
kubernetes v1.1.0-origin-1107-g4c8e6f4
etcd 2.1.2

Answer 1

我忘记打开端口 10250 (tcp)（在我的 aws 安全组中）。 这是我唯一的问题。
