docker搭建系列

本文主要讲如何使用使用docker搭建elasticsearch。

下载镜像

这里利用hangxin1940搭好的镜像,不过是es的1.4.2版本。

docker pull hangxin1940/docker-elasticsearch-cn:v1.6.0

启动容器

docker run -d -p 9200:9200 -p 9300:9300 --name es hangxin1940/docker-elasticsearch-cn:v1.6.0

查看es(这里的ip是docker的default machine的ip)

访问http://192.168.99.100:9200/

{
status: 200,
name: "node1",
cluster_name: "cn-out-of-box",
version: {
number: "1.6.0",
build_hash: "cdd3ac4dde4f69524ec0a14de3828cb95bbb86d0",
build_timestamp: "2015-06-09T13:36:34Z",
build_snapshot: false,
lucene_version: "4.10.4"
},
tagline: "You Know, for Search"
}

查看集群状态

http://192.168.99.100:9200/_plugin/head/

也可以用命令行

curl -XGET http://192.168.99.100:9200/_cluster/health?pretty

返回

{
  "cluster_name" : "cn-out-of-box",
  "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,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0
}

这里目前只是单节点的,后续弄成集群看看。

返回

{
  "_index" : "twitter",
  "_type" : "tweet",
  "_id" : "1",
  "_version" : 1,
  "found" : true,
  "fields" : {
    "message" : [ "trying out Elastic Search" ],
    "user" : [ "kimchy" ]
  }
}

高级查询:选择格式

curl -XGET 'http://192.168.99.100:9200/twitter/tweet/1?fields=message,user&format=yaml'

{"_index":"twitter","_type":"tweet","_id":"1","_version":2,"found":true,"_source":{"message": "hello world", "user": "patterncat"}}%
