<h3>解释：</h3>
<ul>
<li><strong>image</strong>：指定 Elasticsearch 8.17.2 版本的 Docker 镜像。</li>
<li><strong>environment</strong>：设置环境变量：
<ul>
<li><code>discovery.type=single-node</code>：配置 Elasticsearch 以单节点模式运行。</li>
<li><code>ES_JAVA_OPTS</code>：设置 Java 堆内存选项（根据系统的可用内存进行调整）。</li>
<li><code>ELASTIC_PASSWORD</code>：设置默认 <code>elastic</code> 用户的密码（用你自己的密码替换 <code>yourpassword</code>）。</li>
</ul></li>
<li><strong>ulimits</strong>：设置内存锁定限制，防止 Elasticsearch 将内存交换到磁盘。</li>
<li><strong>ports</strong>：映射必要的端口（<code>9200</code> 用于 HTTP，<code>9300</code> 用于节点间通信）。</li>
<li><strong>volumes</strong>：挂载卷来持久化数据。</li>
<li><strong>networks</strong>：定义一个用于 Elasticsearch 服务的自定义网络。</li>
<li><strong>restart</strong>：配置服务为 "除非停止" 的自动重启策略。</li>
</ul>
<p>确保替换密码并根据你的环境需要调整配置。</p>
