# MeBox 第三档完整 Docker Compose 部署文件
#
# 组件：
#   MeBox + PostgreSQL + Redis + OpenSearch
#
# 使用方式二选一：
#   1. 保存为 docker-compose.yml 后执行：
#        docker compose up -d
#   2. 保留本文件名时执行：
#        docker compose -f docker-compose.search.yml up -d
#
# 适合：
#   超大媒体库、复杂全文搜索、后续需要独立搜索索引的部署。
#
# 注意：
#   OpenSearch 常驻内存明显高于 Redis/PostgreSQL。低配 NAS 不建议开启。
#
# 默认账号：
#   admin / admin123
