docker-compose配置elasticsearch启动

version: '3'
services:
  elasticsearch:
    container_name: elasticsearch
    image: elasticsearch:7.7.0
    network_mode: "host"
    restart: always
    ports:
      - "9200:9200"
      - "9300:9300"
    environment:
      - TZ=Asia/Shanghai
      - discovery.type=single-node
      - ES_JAVA_OPTS="-Xms32768m -Xmx32768m"
    restart: always
    volumes:
      - /home/data/pubserver/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
      - /home/data/pubserver/elasticsearch/data:/usr/share/elasticsearch/data
      - /home/data/pubserver/elasticsearch/plugins:/usr/share/elasticsearch/plugins

这里在启动之前也需要在config目录下放置elasticsearch.yml文件，不然启动不起来。可以直接创建一个elasticsearch.yml文件，复制下列内容

cluster.name: "docker-cluster"
network.host: 0.0.0.0

然后启动即可，这里只保证elasticsearch启动起来能正常运行，具体的配置根据实际情况配置操作即可。
