docker - 在Docker堆栈上部署具有JDBC管道的Logstash反复创建新容器

Question

我一直在尝试自学如何在本地计算机上的Docker上部署ELK，以下问题已经出现了一个星期，而我却无法在线找到解决方案。

我在以下配置上运行“docker deploy -c docker-compose.yml elk_stack”。
我面临的问题是，在创建了logstash容器之后，日志显示正确选择了管道配置，并且数据流经了Elasticsearch容器。然后，一旦所有数据移动完毕，logstash容器将自行销毁，并创建一个新容器，该容器遵循与上一个相同的步骤。

为什么会这样呢？

以下是我的docker-compose.yml

Answer 1

这是一个令人讨厌的问题，但是经过反复试验，我找到了答案。

我的问题是我没有在logstash管道配置中配置日程表CRON表达式。

将以下行添加到配置中就可以了。

schedule => "*/10 * * * *"
