- db2/Dockerfile: 多阶段构建(libmsg+db2)，含 schema 初始化 entrypoint - dnfs2/Dockerfile: 多阶段构建(libhttp+libmsg+dnfs2)，curl 健康检查 - .dockerignore: 豁免 libhttp/libmsg 供 C++ 服务构建 两者均基于 ubuntu:24.04(boost 1.83 含 json.hpp)，可平替 Python 版

# dnfs2 Dockerfile — C++20 树状网络文件系统
|
||
# 多阶段构建：第一阶段编译 libhttp + libmsg + dnfs2，第二阶段精简运行时
|
||
#
|
||
# 注：Debian bookworm 的 boost 版本为 1.74，不含 boost/json.hpp（需 1.75+），
|
||
# 因此选用 Ubuntu 24.04（boost 1.83）作为基础镜像。
