要使用 Docker Compose 搭建一个 Elasticsearch 集群，并配置为不使用验证，同时使用 HTTP 访问，你可以遵循以下步骤：

步骤 1: 安装 Docker 和 Docker Compose

确保你的系统上已安装 Docker 和 Docker Compose。如果尚未安装，请访问 Docker 的官方网站进行安装。

步骤 2: 创建 Docker Compose 配置文件

创建一个名为 docker-compose.yml 的文件，其中包含 Elasticsearch 集群的配置。以下是一个示例配置：

version: '3'
services:
  es01:
    image: docker.elastic.co/elasticsearch/elasticsearch:8.11.3
    container_name: es01
    environment:
      - node.name=es01
      - cluster.name=es-docker-cluster
      - discovery.seed_hosts=es02,es03
      - cluster.initial_master_nodes=es01,es02,es03
      - bootstrap.memory_lock=true
      - xpack.security.enabled=false
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    volumes:
      - /home/sunyuhua/dockercom/es/es01/data:/usr/share/elasticsearch/data
      - /home/sunyuhua/dockercom/es/es01/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
    ulimits:
      memlock:
        soft: -1
        hard: -1
    ports:
      - 9200:9200
    networks:
      - esnet

  es02:
    image: docker.elastic.co/elasticsearch/elasticsearch:8.11.3
    container_name: es02
    environment:
      - node.name=es02
      - cluster.name=es-docker-cluster
      - discovery.seed_hosts=es01,es03
      - cluster.initial_master_nodes=es01,es02,es03
      - bootstrap.memory_lock=true
      - xpack.security.enabled=false
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    volumes:
      - /home/sunyuhua/dockercom/es/es02/data:/usr/share/elasticsearch/data
      - /home/sunyuhua/dockercom/es/es02/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml    
    ulimits:
      memlock:
        soft: -1
        hard: -1
    networks:
      - esnet

  es03:
    image: docker.elastic.co/elasticsearch/elasticsearch:8.11.3
    container_name: es03
    environment:
      - node.name=es03
      - cluster.name=es-docker-cluster
      - discovery.seed_hosts=es01,es02
      - cluster.initial_master_nodes=es01,es02,es03
      - bootstrap.memory_lock=true
      - xpack.security.enabled=false
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    volumes:
      - /home/sunyuhua/dockercom/es/es03/data:/usr/share/elasticsearch/data
      - /home/sunyuhua/dockercom/es/es03/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
    ulimits:
      memlock:
        soft: -1
        hard: -1
    networks:
      - esnet

networks:
  esnet:
    driver: bridge

在这个配置中：

使用了 Elasticsearch 7.10.0 版本。
配置了三个节点的 Elasticsearch 集群。
xpack.security.enabled=false 禁用了 X-Pack 安全性（去除验证）。
暴露了第一个节点的 9200 端口用于 HTTP 访问。

并编辑elasticsearch.yml 将https验证去掉

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