[英]Kubernetes readiness probe warning has no details
I've made a deployment in GKE with a readiness probe.我已经使用就绪探测在 GKE 中进行了部署。 My container is coming up but it seems the readiness probe is having some difficulty.
我的容器即将出现,但准备就绪探测似乎遇到了一些困难。 When I try to describe the pod I see that there are many probe warnings but it's not clear what the warning is.
当我尝试描述 pod 时,我看到有很多探测警告,但不清楚警告是什么。

Regarding the error in the logs “DeprecationWarning: The legacy HTTP parser is deprecated.”关于日志中的错误“DeprecationWarning:旧版 HTTP 解析器已弃用。” , it is due to the legacy HTTP parser being deprecated with the pending End-of-Life of Node.js 10.x .
,这是由于遗留的 HTTP 解析器被弃用,Node.js 10.x 的生命周期即将结束。 It will now warn on use, but otherwise continue to function and may be removed in a future Node.js 12.x release.
它现在会在使用时发出警告,但在其他方面会继续到 function,并且可能会在未来的Node.js 12.x版本中删除。 Use this URL for more reference Node v12.22.0 (LTS) .

On the other hand, about the kubelet
's “ProbeWarning” reason in the warning events on your container, Health check (liveness & readiness) probes using an HTTPGetAction will no longer follow redirects to different host-names from the original probe request.另一方面,关于容器警告事件中
kubelet
的“ProbeWarning”原因,使用HTTPGetAction的健康检查(活动性和就绪性)探测将不再遵循与原始探测请求不同的主机名的重定向。 Instead, these non-local redirects will be treated as a Success (the documented behavior).相反,这些非本地重定向将被视为成功(记录的行为)。 In this case an event with reason "ProbeWarning" will be generated, indicating that the redirect was ignored.
在这种情况下,将生成原因为“ProbeWarning”的事件,指示重定向被忽略。 If you were previously relying on the redirect to run health checks against different endpoints, you will need to perform the healthcheck logic outside the Kubelet , for instance by proxying the external endpoint rather than redirecting to it.
如果您之前依赖重定向对不同的端点运行健康检查,您将需要在Kubelet外部执行健康检查逻辑,例如通过代理外部端点而不是重定向到它。 You can verify the detailed root cause of this in the following Kube.netes 1.14 release notes .
您可以在以下Kube.netes 1.14 发行说明中验证详细的根本原因。 There is no way to see more detailed information about the “ProbeWarning” in the Events' table.
无法在事件表中查看有关“ProbeWarning”的更多详细信息。 Use the following URLs as a reference too Kube.netes emitting ProbeWarning , Confusing/incomplete readiness probe warning and Add probe warning message body .
