镜像生成器线程失败_大数据知识库

我配置了swarm网络，在docker堆栈中尝试从服务运行kafka mirrormake时，从服务日志中得到一个错误：

mirroring_mirror_maker | [2019-01-10 12:08:49,322] ERROR [mirrormaker-thread-1] Mirror maker thread failure due to  (kafka.tools.MirrorMaker$MirrorMakerThread)
mirroring_mirror_maker | java.lang.IllegalStateException: No entry found for connection 2147482646

我的 consumer.properties 代码：

bootstrap.servers=kafka:9094
group.id=mm-consumer-group
partition.assignment.strategy=org.apache.kafka.clients.consumer.RoundRobinAssignor

看一下密码 producer.properties 吼叫：

bootstrap.servers=10.1.1.10:9094
compression.type=none

从docker堆栈运行命令：

kafka-mirror-maker.sh --consumer.config /opt/kafka/config/consumer.properties --num.streams 2 --producer.config /opt/kafka/config/producer.properties --whitelist=".*"

如果我从我的主机运行相同的命令，它就会工作。
更多日志输出：

经过研究，解决方案很快很简单，我不得不添加一个主机Map extra_hosts 在我的 docker-compose.yml 文件。

version: '3.6'

x-proxy: &proxy
  http_proxy: ${http_proxy}
  https_proxy: ${https_proxy}
  no_proxy: ${no_proxy}

services:
  mirror_maker:
    image: wurstmeister/kafka:2.12-2.1.0
    configs:
      - source: mm-consumer-config
        target: /opt/kafka/config/consumer.properties
      - source: mm-producer-config
        target: /opt/kafka/config/producer.properties
    environment:
      <<: *proxy
    command: kafka-mirror-maker.sh --consumer.config /opt/kafka/config/consumer.properties --num.streams 2 --producer.config /opt/kafka/config/producer.properties --whitelist=.*
    networks:
      - workshop
    extra_hosts:
      - outside:10.1.1.10
      - manager:10.1.1.11
    restart: always
    depends_on:
      - zookeeper
      - kafka
    deploy:
      # replicas: 2
      placement:
        constraints:
          - node.role == manager

configs:
  mm-consumer-config:
    file: ./services/mirror_maker/config/consumer.properties
  mm-producer-config:
    file: ./services/mirror_maker/config/producer.properties

networks:
  workshop:
    name: workshop
    external: true
