elasticsearch 6.2.4和elasticsearch-head测试环境搭建 使用docker-compose方式

一 背景说明

对于新手来说搭建一个elasticsearch的测试环境稍微费力，而且没必须要去下载那么多安装包，比如java node npm等，所以我决定做成docker-compose方式的启动，并且集成ik分词器，方便快捷，一键搞定。

二 环境需求

你电脑需要安装docker和docker-compose

三 使用步骤

1 目录结构

.
├── docker-compose-elastic.yml
└── elasticsearch.yml

elasticsearch.yml

先编写elasticsearch的配置文件，后续是需要挂载到docker容器中的
elasticsearch.yml的内容如下：

network.bind_host: 0.0.0.0
cluster.name: elastic-cluster
network.host: 0.0.0.0
discovery.zen.minimum_master_nodes: 1
bootstrap.memory_lock: true
discovery.type: single-node
http.cors.enabled: true
http.cors.allow-origin: "*"

docker-compose-elastic.yml

docker-compose-elastic.yml 这里docker-compose需要的配置文件
elasticsearch.yml的内容如下：

version: '2'
services:
  elastic:
    image: bachue/elasticsearch-ik:6.2.4
    container_name: elastic
    environment:
      - TZ='Asia/Shanghai'
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    mem_limit: 1g
    volumes:
      - ./elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
      - ./data:/usr/share/elasticsearch/data
    ports:
      - 9200:9200
      - 9300:9300
  elasticsearch-head:
      image: wallbase/elasticsearch-head:6-alpine
      container_name: elasticsearch-head
      environment:
        TZ: 'Asia/Shanghai'
      ports:
        - '9100:9100'

docker-compose配置说明

bachue/elasticsearch-ik:6.2.4 表示是带有ik分词的，不需要额外自己安装，
volumes 配置项主要是把本地文件挂载到容器中，包含配置文件和数据目录，data是数据目录，如果你只是测试，也可以不需要，但是你下次启动数据就丢失了。
wallbase/elasticsearch-head:6-alpine 从5.0之后head插件可以独立启动，我重新打包一个支持6.2.x版本的docker镜像上传的hub.docker.com中的。

四 启动

启动elasticsearch和elasticsearch-head,参数-d表示后台启动，当然你需要交互式启动可以把-d去掉,elasticsearch端口是9200,head插件的访问端口是9100

如上，es报错

从上面可以看挂载的data目录没有权限
所以要给一下权限
