一、背景

基于K8s集群的私有化交付方案中，日志收集采用了ilogtail+logstash+kafka+es方案，其中ilogtail負責日志收集，logstash負責對數據轉換，kafka負責對日志傳遞中的消峰進而減少es的寫入壓力，es用來保存日志數據。在私有化交付中本方案中涉及的中間件一般需要單獨部署，但是在京東內網環境的部署考慮到kafka和es的高可用，則不推薦采用單獨部署的方案。

二、新方案實踐

1.新方案簡介

在京東內網環境部署K8S并收集日志， kafka+es的替代方案考慮使用JMQ+JES，由于JMQ的底層是基于kafaka、JES的底層基于ES，所以該替換方案理論上是可行的

2.主要架構

數據流向大致如下
應用日志 -> ilogtail -> JMQ -> logstash -> JES

3.如何使用

核心改造點匯總

ilogtail nameservers配置
增加解析JMQ域名的nameserver（京東云主機上無法直接解析.local域名）

spec:
    spec:
      dnsPolicy: "None"
      dnsConfig:
        nameservers:
          - x.x.x.x # 可以解析jmq域名的nameserver

ilogtail flushers配置
調整發送到JMQ到配置

apiVersion: v1
kind: ConfigMap
metadata:
  name: ilogtail-user-cm
  namespace: elastic-system
data:
  app_stdout.yaml: |
    flushers:
      - Type: flusher_stdout
        OnlyStdout: true
      - Type: flusher_kafka_v2
        Brokers:
          - nameserver.jmq.jd.local:80 # jmq元數據地址
        Topic: ai-middle-k8s-log-prod # jmq topic 
        ClientID: ai4middle4log # Kafka的用戶ID（識別客戶端并設置其唯一性），對應jmq的Group名稱，重要?? （https://ilogtail.gitbook.io/ilogtail-docs/plugins/input/service-kafka#cai-ji-pei-zhi-v2）

logstash kafka&es配置

apiVersion: v1
kind: ConfigMap
metadata:
  name: logstash-config
  namespace: elastic-system
  labels:
    elastic-app: logstash
data:
  logstash.conf: |-
    input {
        kafka {
                bootstrap_servers => ["nameserver.jmq.jd.local:80"] #jmq的元數據地址
                group_id => "ai4middle4log" # jmq的Group的名稱
                client_id => "ai4middle4log" # jmq的Group的名稱，即jmq的省略了kafka中的client_id概念，用Group名稱代替
                consumer_threads => 2
                decorate_events => true
                topics => ["ai-middle-k8s-log-prod"] # jmp的topic
                auto_offset_reset => "latest"
                codec => json { charset => "UTF-8" }
        }
    }
    output {
        elasticsearch {
                hosts => ["http://x.x.x.x:40000","http://x.x.x.x:40000","http://x.x.x.x:40000"] # es地址
                index =>  "%{[@metadata][kafka][topic]}-%{+YYYY-MM-dd}" # 索引規則
                user => "XXXXXX" #jes的用戶名
                password => "xxxxx" #jes的密碼
                ssl => "false"
                ssl_certificate_verification => "false"
        }
    }

ilogtail 的配置如下

4.核心價值

在私有化部署的基礎上通過簡單改造實現了與京東內部中間件的完美融合，使得系統在高可用性上適應性更強、可用范圍更廣。
