Docker中运行的Elasticsearch 6.4,go无法

启动go应用，报错："no active connection found: no Elasticsearch node available"

docker-compose文件

    image: elasticsearch:6.4.2
    network_mode: "bridge"
    expose:
      - "9200"
      - "9300"
    volumes:
      - ./es-data:/usr/share/elasticsearch/data
    ports:
      - "9200:9200"
      - "9300:9300"

go代码

esClient, esClientErr :=             
elastic.NewClient(elastic.SetURL("http://127.0.0.1:9200"))
if esClientErr != nil {
    return nil, fmt.Errorf("Failed to connect to ES: %v", esClientErr)
}

异常

Failed to connect to ES: no active connection found: no Elasticsearch node available

解决方法,elasticsearch.yml增加这行，重启容器

network.publish_host: "_local_"

问题解决
