Enforce DCO per repo or org

[caniszczyk]

it would be great to have DCO enforced on a repo

An external tool like PullApprove handles this already:

Here's a work in progress GitHub Integration that adds DCO checks on commits and pull requests: dcoapp/app#2

It's only a few hours old, so it's not ready for production use yet, but feel free to follow along for updates there. Feature requests welcome.

FYI @mkdolan

I think the integration linked to above solves this and will likely be the preferred way to enforce the DCO going forward.
