        source: ./data
        target: /usr/share/elasticsearch/data
    ports:
      - "9200:9200"
      - "9300:9300"
    healthcheck:
      test: ["CMD-SHELL", "curl --silent --fail localhost:9200/_cluster/health || exit 1"]

这个Docker Compose文件定义了一个单节点Elasticsearch集群。它将Elasticsearch配置文件挂载到服务的elasticsearch.yml，同时将数据卷挂载到容器的data目录。它还暴露了Elasticsearch的默认端口9200和9300，这是Elasticsearch节点之间通信所使用的端口。最后，它配置了一个健康检查，以确保Elasticsearch服务在启动之前就绪。
