DCO（Developer Certificate of Origin）是一种轻量级的贡献者声明机制，由 Linux 基金会制定，被 Linux 内核、Kubernetes 等大型开源项目广泛采用。
与 CLA（贡献者许可协议）相比，DCO 更加简单：
- 无需签署额外的法律文件
- 只需在 commit 时添加
-s标志即可 - 表明你有权提交该贡献，且同意以项目许可证（AGPL-3.0）发布
git commit -s -m "feat: your feature description"这会自动在 commit message 中添加：
Signed-off-by: Your Name <your.email@example.com>
确保你的 Git 配置了正确的姓名和邮箱：
git config --global user.name "Your Name"
git config --global user.email "your.email@example.com"
