无法让 FileBeat 发布到 Elastic Search答案

【问题描述】：

我有一个 kuberenetes 集群，我正在尝试从集群中的容器收集日志。我正在使用 Filebeat 收集日志并将其发送到弹性搜索，然后在 Kibana 中显示。我部署了 Kibana 和弹性搜索，它运行良好。我正在使用 DaemonSet 来部署 FileBeat。这是我用来部署 Filebeat 的 YAML 文件。我使用这里的清单文件来部署它并对其进行了一些修改。

我检查了运行 Filebeat 的 pod，它存储了日志。但不知何故，它不会将其发布到弹性搜索。我的确切配置应该是什么才能将其发布到elasticsearch。我已经坚持了几天了，我没有选择。任何帮助将不胜感激。

【解决方案1】：

您的 filebeat 配置未选择任何输入类型。

filebeat.yaml 文件输入路径必须指向您的 filebeats-inputs.yaml 而不是日志位置。这反过来又委托给 docker 输入类型。默认的 containers.path 是 /var/lib/docker/containers。
