docker安装elasticsearch

docker-compose.yml安装:

version: "3.1"
services:
  elasticsearch:
    image: daocloud.io/library/elasticsearch:7.17.0
    restart: always
    container_name: elasticsearch
    ports:
      - 9200:9200
    environment:
      - discovery.type=single-node #发现类型设置为单节点
    volumes:
      - /opt/docker_es/plugins:/usr/share/elasticsearch/plugins
  kibana:
    image: daocloud.io/library/kibana:7.17.0 #kibana版本需与elasticsearch版本一致
    restart: always
    container_name: kibana
    ports:
      - 5601:5601
    environment:
      - elasticsearch_url=http://127.0.0.1:9200
    depends_on:
      - elasticsearch

务必将elasticsearch的环境变量"发现类型"设置为"single-node",否则运行将报如下错误:
[o.e.b.BootstrapChecks ] [SoOliDl] bound or publishing to a non-loopback address, enforcing bootstrap checks
ERROR: [1] bootstrap checks failed
