    基于 Docker 构建 ElasticSearch

    基于 Docker 构建 ElasticSearch

    ARCHIVE 这篇写于 2017 年,距今 8 年多了。里面的版本、链接和做法可能都已经过时,看的时候留个心眼。

    本文是一篇基于 Docker 构建 ElasticSearch 的入门级指南。
    

    其实用 Docker 来构建真的很简单,这里就给大家贴我的实际配置和运行命令吧。

    。。。

    检查 ElasticSearch 状态

    curl -XGET http://localhost:9200/_cluster/health?pretty

    {
      "cluster_name" : "docker-cluster",
      "status" : "yellow",
      "timed_out" : false,
      "number_of_nodes" : 1,
      "number_of_data_nodes" : 1,
      "active_primary_shards" : 1,
      "active_shards" : 1,
      "relocating_shards" : 0,
      "initializing_shards" : 0,
      "unassigned_shards" : 1,
      "delayed_unassigned_shards" : 0,
      "number_of_pending_tasks" : 0,
      "number_of_in_flight_fetch" : 0,
      "task_max_waiting_in_queue_millis" : 0,
      "active_shards_percent_as_number" : 50.0
    }
    

    增删改查

    增加

    curl -XPUT 'localhost:9200/twitter/tweet/1?pretty' -H 'Content-Type: application/json' -d'
    {
        "user" : "kimchy",
        "post_date" : "2009-11-15T14:12:12",
        "message" : "trying out Elasticsearch"
    }
    '
    

    执行结果:

    {
      "_index" : "twitter",
      "_type" : "tweet",
      "_id" : "1",
      "_version" : 1,
      "result" : "created",
      "_shards" : {
        "total" : 2,
        "successful" : 1,
        "failed" : 0
      },
      "_seq_no" : 0,
      "_primary_term" : 1
    }
    

    查询

    curl -XGET 'http://localhost:9200/twitter/tweet/1'

    执行结果:

    {"_index":"twitter","_type":"tweet","_id":"1","_version":1,"found":true,"_source":
    {
        "user" : "kimchy",
        "post_date" : "2009-11-15T14:12:12",
        "message" : "trying out Elasticsearch"
    }
    }
