Docker-compose elastic stack 无容器标签

Question

我有一个带有 docker-compose 和弹性堆栈的设置。我的 'main' 容器是运行一个 Django 应用程序（还有一些用于度量、证书等的容器）。

日志记录本身适用于此设置，但我在 Kibana 中没有容器标签或标签。所以我无法区分来自不同容器的日志（除非我知道我在寻找什么）。

如何配置 logstash 或 logspout 以使用它们来自的容器来标记或标记所有日志？在最好的情况下标记容器图像和容器 ID。

我尝试给容器添加标签，但没有任何改变。我还尝试了指定的日志记录，使用驱动程序系统日志和标签，但这也没有用。

我想我必须做一个特定的 logstash 配置并在那里做一些事情？

下面是我现在的docker-compose.yml

version: '2'

services:
    # django container
    web:
        build: .
        command: gunicorn backend.wsgi:application --bind 0.0.0.0:8001 --log-level debug

        container_name: web
        depends_on:
            - logspout

            com.example.service: "web"

    logspout:

    kibana:

            - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
            - cluster.initial_master_nodes=elasticsearch

任何帮助将不胜感激，谢谢！

抱歉，我对elastic stack真的是一窍不通，不过我做对了。

确实，您必须提供带过滤器的 logstash 配置，至少我是这样让它工作的。此外，我不得不在 logspout 中从 UDP 切换到 syslog，我猜 udp 连接没有转发它得到的所有内容（例如 docker 图像）。

这是我的有效配置（肯定有一些改进要做）。

logstash.conf

input {
  syslog {
      port => 5000
      type => "docker"
  }
}

filter {
  grok {
    match => { "message" => "%{SYSLOG5424PRI}%{NONNEGINT:ver} +(?:%{TIMESTAMP_ISO8601:ts}|-) +(?:%{HOSTNAME:service}|-) +(?:%{NOTSPACE:containerName}|-) +(?:%{NOTSPACE:proc}|-) +(?:%{WORD:msgid}|-) +(?:%{SYSLOG5424SD:sd}|-|) +%{GREEDYDATA:msg}" }
  }
  syslog_pri { }
}

output {
  elasticsearch { hosts => "elasticsearch" }
  stdout {codec => rubydebug}
}

docker-compose.yml
