如何运行需要 Elasticsearch 认证的 beat 容器

Question

主要目的：我想使用Logstash收集依赖远程服务器的日志文件。

我的 ELK 堆栈是使用 docker-compose.yml

创建的

version: '3.3'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.5.1
    ports:
      - "9200:9200"
      - "9300:9300"
    volumes:
      - '/share/elk/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml:ro'
    environment:
      ES_JAVA_OPTS: "-Xmx512m -Xms256m"
      ELASTIC_PASSWORD: changeme
      discovery.type: single-node
    networks:
      - elk
    deploy:
      mode: replicated
      replicas: 1
  logstash:
    image: docker.elastic.co/logstash/logstash:7.5.1
    ports:
      - "5000:5000"
      - "9600:9600"
    volumes:
      - '/share/elk/logstash/config/logstash.yml:/usr/share/logstash/config/logstash.yml:ro'
      - '/share/elk/logstash/pipeline/logstash.conf:/usr/share/logstash/pipeline/logstash.conf:ro'
    environment:
      LS_JAVA_OPTS: "-Xmx512m -Xms256m"
    networks:
      - elk
    deploy:
      mode: replicated
      replicas: 1
      
  kibana:
    image: docker.elastic.co/kibana/kibana:7.5.1
    ports:
      - "5601:5601"
    volumes:
      - '/share/elk/kibana/config/kibana.yml:/usr/share/kibana/config/kibana.yml:ro'
    networks:
      - elk
    deploy:
      mode: replicated
      replicas: 1

networks:
  elk:
    driver: overlay

然后我想在目标主机上安装一个filebeat，以便将日志发送到ELK主机。

docker run docker.elastic.co/beats/filebeat-oss:7.5.1 setup \
-E setup.kibana.host=x.x.x.x:5601  \
-E ELASTIC_PASSWORD="changeme" \
-E output.elasticsearch.hosts=["x.x.x.x:9200"]

但是一按回车就出现错误

Exiting: Couldn't connect to any of the configured Elasticsearch hosts. Errors: [Error connection to Elasticsearch http://x.x.x.x:9200: 401 Unauthorized: {"error":{"root_cause":[{"type":"security_exception","reason":"missing authentication credentials for REST request [/]","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}}],"type":"security_exception","reason":"missing authentication credentials for REST request [/]","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}},"status":401}]

也试过 -E ELASTICS_USERNAME="elastic" 错误仍然存在

您应该禁用 Elasticsearch 7.X 版本中默认启用的基本 x-pack 安全性，在 ES docker 映像的环境变量下，如下所述并启动 ES docker容器。

xpack.security.enabled : false

在此之后，无需传递 ES 凭据，您也可以从您的 ES 环境中删除以下内容。变量：

ELASTIC_PASSWORD: changeme
