docker-compose部署elasticsearch集群

　　一、准备基础镜像

docker pull elasticsearch:7.3.2

　　二、dockerfile(Dockerfile-elasticsearch)，为了保护原生的镜像

FROM elasticsearch:7.3.2
MAINTAINER lilin
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

　　三、集群配置

version: '2'
services:

  es-1:
    build:
      context: ./
      dockerfile: ./Dockerfile/Dockerfile-elasticsearch
    image: es-1
    restart: always
    container_name: es-1
    environment:
      - ES_JAVA_OPTS=-Xms1g -Xmx1g -XX:+HeapDumpOnOutOfMemoryError
      - cluster.name=cluster
      - node.name=es-1
      - node.master=true
      - network.host=0.0.0.0
      - http.port=9200
      - transport.tcp.port=9300
      - discovery.seed_hosts=es-1:9300
      - cluster.initial_master_nodes=es-1
      - xpack.sql.enabled=false　　
    volumes:
      - /usr/share/elasticsearch/data-1:/usr/share/elasticsearch/data
      - /usr/share/elasticsearch/plugins-1:/usr/share/elasticsearch/plugins
    ports:
      - 9200:9200

  es-2:
    build:
      context: ./
      dockerfile: ./Dockerfile/Dockerfile-elasticsearch
    image: es-2
    restart: always
    container_name: es-2
    environment:
      - ES_JAVA_OPTS=-Xms1g -Xmx1g -XX:+HeapDumpOnOutOfMemoryError
      - cluster.name=cluster
      - node.name=es-2
      - node.master=true
      - network.host=0.0.0.0
      - http.port=9201
      - transport.tcp.port=9301
      - discovery.seed_hosts=es-1:9300,es-2:9301
      - cluster.initial_master_nodes=es-1,es-2
      - xpack.sql.enabled=false
    volumes:
      - /usr/share/elasticsearch/data-2:/usr/share/elasticsearch/data
      - /usr/share/elasticsearch/plugins-2:/usr/share/elasticsearch/plugins
    ports:
      - 9201:9201

　　四、启动测试
