Docker中运行的Elasticsearch 6.4,go无法

作者: gurlan | 来源:发表于2020-03-01 12:19 被阅读0次

    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

    访问:http://127.0.0.1:9200/_nodes/http?pretty

    
    {
      "_nodes" : {
        "total" : 1,
