Question

我正在尝试为通过AWS Elasticsearch在Kubernetes上运行的应用程序设置监视解决方案。

要发送日志，我正在使用filebeat-> Logstash-> AWS ElasticSearch，到目前为止，它被证明是一场噩梦:(

要从logstash发送日志，我需要使用amazon_es输出插件，但会出现不同的错误

下面是我正在使用的logstash的清单文件

kind: ConfigMap

  logstash.yml: |
    http.host: "0.0.0.0"
    path.config: /usr/share/logstash/pipeline
  logstash.conf: |
    # all input will come from filebeat, no local logs
    input {
      beats {
        port => 5044
      }
    }
    filter {
      if [message] =~ /^\{.*\}$/ {
        json {
          source => "message"
        }
      }
      if [ClientHost] {
        geoip {
          source => "ClientHost"
        }
      }
    }
    output {
        amazon_es {
            hosts => [ "https://vpc-eks***********.es.amazonaws.com:443" ]
            region => "eu-west-1"
            index => "devtest-logs-%{+YYYY.MM.dd}"            
        }
    }

到目前为止，由于容器进入崩溃循环，我一直找不到任何东西。任何帮助都很好

您需要安装amazon_es插件才能解决此问题。

将此内容包含在您的dockerfile中。

RUN logstash-plugin install logstash-output-amazon_es

在Kubernetes上安装Logstash并将日志发送到AWS ElasticSearch
