novalon-website/infra/cicd/docker-compose.gitea.yml

# ============================================================
# Gitea 生产环境编排（加固版）
# 部署位置: 139.155.109.62:/home/novalon/docker-app/novalon-cicd/
# 访问地址: https://git.f.novalon.cn
#
# 相对现状（2026-09-14 实测）的修复点：
#   1. 凭据外置到 .env，不再内联在 compose 里
#   2. SSH_PORT 22 -> 2222，修正"克隆地址指向宿主 sshd"的错配
#   3. 资源限制改用 compose 原生 cpus/mem_limit（deploy: 段在非 swarm 下被忽略，等于没限制）
#   4. 补 read_only / cap_drop / tmpfs 最小权限
#   5. 补 PostgreSQL 日志轮转与备份卷
#
# 用法:
#   cp .env.example .env && vim .env      # 填入真实凭据，.env 绝不入库
#   docker compose -f docker-compose.gitea.yml up -d
