方案1: docker-compose 双容器(原有,不变) 方案2: 二进制部署(go:embed 前端嵌入) - 修复 SPA fallback(c.FileFromFS 301 → c.Data 直接返回) - 二进制 22MB,内存 21.5MB - 支持全部 CLI 参数(--db-host --redis-host --port 等) 方案3: K8s 部署(hostNetwork + 外部 MySQL/Redis) - devops 声明空间 - embed 单容器 Deployment + NodePort Service - 健康检查改为 /version(/health 尚未实现) - hostNetwork 解决 K8s pod 网络到外部 MySQL 的连通性 新增: Dockerfile.embed, docker-compose.embed.yml, deploy/binary/
