将日志从另一个群集堆栈发送到logstash

Question

我的Docker集群中有2个堆栈。一个是麋鹿（弹性搜索，Kibbana和Logstash），另一个是我的Web应用程序。

出于某些原因，我不想为麋鹿和应用程序服务使用相同的堆栈。

我想使用syslog将我的Web应用访问日志发送到Logstash。我使用ping命令测试了麋鹿堆栈，以验证其工作正常。然后，在我的应用程序中设置日志记录驱动程序，并创建过多的网络，甚至使用外部链接。但是似乎没有任何作用，并且由于记录了驱动程序服务发现，我的应用程序服务也没有启动。

starting container failed: failed to initialize logging driver: dial tcp: lookup logstash on 10.131.57.151:53

这是我的麋鹿堆栈撰写文件：
