name: Deploy

# 部署到服务器
# 触发条件：main 分支 docker.yml 完成后 自动，或手动 workflow_dispatch
# 部署方式：Runner 直接执行 docker compose（Runner 跑在服务器上）
#
# 前置条件（一次性配置）：
#   1. 服务器上已安装 Gitea Actions Runner，标签为 'ubuntu-latest'
#   2. 服务器上已存在 /opt/edu/docker-compose.deploy.yml（由 SRE AI 首次部署）
#   3. 服务器上已存在 /opt/edu/.env（含生产 JWT_SECRET 等）
#   4. 服务器 Docker 已登录 Gitea Container Registry：
#      docker login git.eazygame.cn -u <user> -p <token>
#   5. MySQL + Redis 已在服务器 Docker 中运行（3306/6379）
