SCDF Stream保持“正在部署”状态

我们在Kubernetes中部署了SCDF。通过SCDF UI，我们可以使用基于Docker的Source，Processor和Sink应用程序创建流。但是，在部署流时，状态不会从“正在部署”更改，并且最终会失败。我们尝试设置“ CPU和请求”属性的限制，但这无济于事。

应用程序日志显示Tomcat尚未初始化，因为未激活“活动性和就绪性”探针的结果导致未公开哪些/ actuator端点。

对这个问题可能是什么以及如何解决这个问题有任何想法吗？

答案 0 :(得分：0)

SCDF / Skipper日志实际上并没有包含太多信息。也没有任何关于失败的报道。

这里有一些标准要检查的东西。

1）如果您在Minikube或真实的K8s集群中运行SCDF，请确保集群中有足够的可用资源容量。您可以通过描述K8s节点或使用诸如Octant之类的工具来确认是否有足够的CPU或内存可用。

2）请注意，通过SCDF部署的服务以及流/任务应用程序数量越多，您在K8s集群中所需的资源就越多。例如，如果您要配置Prometheus + Grafana来监视SCDF中的流/任务应用程序，则它们两者的组合至少需要3G内存。再次，资源限制错误将出现在群集节点中。

3）查看流/任务窗格日志。还描述K8​​中的流/任务窗格，以查看准备就绪/活动性探针为何失败-错误将在输出的最后显示。
