我没有找到一种正确有效的方法来通过 docker 环境中的 Fluentd 从 Spring Boot docker 收集日志到 Elasticsearch。我的配置如下

spring-boot jar 的 Dockerfile：

FROM openjdk:8-jdk-alpine

ARG JAR_FILE=target/user-management.jar

EXPOSE 10010

COPY ${JAR_FILE} user-management.jar

ENTRYPOINT ["java", "-jar", "user-management.jar"]

Logback 配置- logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="net.logstash.logback.encoder.LogstashEncoder"/>
    </appender>

    <appender name="FILE" class="ch.qos.logback.core.FileAppender">
        <file>/var/log/tests.log</file>
        <encoder class="net.logstash.logback.encoder.LogstashEncoder"/>
    </appender>

    <logger name="jsonLogger" level="DEBUG">
        <appender-ref ref="CONSOLE"/>
    </logger>

    <logger name="com.xyz.usermanagement" level="DEBUG">
        <appender-ref ref="FILE" />
    </logger>

    <root level="INFO">
        <appender-ref ref="CONSOLE"/>
    </root>

</configuration>

Fluentd 配置- fluent.conf

<source>
  @type forward
  port 24224
  bind 0.0.0.0
</source>

<label @FLUENT_LOG>
  <match *.**>
    @type copy
    <store>
      @type elasticsearch
      host elasticsearch
      port 9200
      logstash_format true
      logstash_prefix fluentd
      logstash_dateformat %Y%m%d
      include_tag_key true
      type_name access_log
      tag_key @log_name
      flush_interval 5s
    </store>
    <store>
      @type stdout
    </store>
  </match>
</label>

下面是我用来构建服务的 docker-compose

version: '3.8'

services:

  elasticsearch:
    container_name: elasticsearchsrvc
    image: elasticsearch:7.10.1
    environment:
      - "discovery.type=single-node"
      - xpack.security.enabled=false
    volumes:
      - elasticsearchdata:/usr/share/elasticsearch/data
    networks:
      - microservicesntwrk
    ports:
      - 9200:9200

  fluentd:
    container_name: fluentdsrvc
    image: fluentdimg:0.0.1
    build:
      context: ../fluentd/
    volumes:
      - ./fluentd/conf:/fluentd/etc
    networks:
      - microservicesntwrk
    ports:
      - 24224:24224

  kibana:
    container_name: kibanasrvc
    image: kibana:7.10.1
    environment:
      - ELASTICSEARCH_HOSTS=http://elasticsearchsrvc:9200
    networks:
      - microservicesntwrk
    depends_on:
      - elasticsearch
    ports:
      - 5601:5601

  usermanagement:
    container_name: usermanagementsrvc
    image: usermanagementimg:0.0.1
    build:
      context: ../business/user-management
    depends_on:
      - fluentd
    ports:
      - 10010:10010
    networks:
      - microservicesntwrk

volumes:
  elasticsearchdata:
    driver: local


networks:
  microservicesntwrk:
    driver: bridge
    name: microservicesntwrk

我能够在弹性搜索中看到 Fluentd 服务生成的日志，但看不到用户管理（Spring-Boot）docker 容器生成的日志。

对此的任何方向表示赞赏，谢谢。
