Question

我正在尝试使用Openshift在线发布我的仓库中的一些代码。我的构建编译良好，但部署失败：

error: update acceptor rejected nodejs-mongo-persistent-7: pods for rc "nodejs-mongo-persistent-7" took longer than 600 seconds to become ready

查看事件监视器，我看到了这些错误：

Liveness probe failed: Get http://10.129.127.123:8080/pagecount: dial tcp 10.129.127.123:8080: getsockopt: connection refused
Readiness probe failed: Get http://10.129.127.123:8080/pagecount: dial tcp 10.129.127.123:8080: getsockopt: connection refused

此错误大约发生50次，直到所有内容超时并且我的吊舱被杀死。

我不是一个真正的服务器人，之前从未使用过环境，所以大多数帮助资源我都不明白。

以下是事件日志的屏幕截图： http://imgur.com/a/yv3fA

Answer 1

首先，你的Pod暴露了Liveness和Readiness探针需要的端口，这在Pod配置中完成。

活动探测由kubelet执行，因此所有请求都在kubelet网络命名空间中进行。

请确保不要在服务端口上运行探测，而是运行本地端口。

准备/活动探测失败。杀荚
