# Patbond MVP 编排（ADR-007）：应用容器无状态，PostgreSQL 数据落 volume。
# 使用步骤见 Readme.md「Docker Compose」一节：
#   1) ./deploy/init-secrets.sh        生成 RS256 密钥对与 .env（均不入库）
#   2) JAVA_HOME=... ./mvnw -DskipTests package
#   3) docker compose up -d --build
#
# 配置来源：容器内挂载各服务的 application.yml.sample 作为配置文件，
# 其中的 ${PATBOND_*} 占位由下方 environment 注入 —— 与本机运行同一套约定。
