所以 Vespa 非常酷和有用，但它真的很难掌握：/ 例如，我现在已经在 k8 上将它容器化并部署了我的应用程序。（在一个 pod/节点中配置和搜索/存储节点，节点发行版是谷歌自己的容器优化操作系统）。我可以在几分钟内通过 REST/document API 放置文档和查询文档……太棒了！但是几分钟后它只是进入了一些错误状态。
我必须重新部署应用程序并再次激活它才能开始工作。
执行到 pod/container 和 vespa-logfmt -l all -s fmttime,service,message
说（我不知道这里发生了什么，但有些东西进入了失败状态）。为什么要更新配置服务器并重新部署所有应用程序等？我可以协助调试正在发生的事情的任何其他日志？
