DCO Sign Off

All contributors to the project retain copyright to their work, but must only submit work which they have the rights to submit.

We require all contributors to acknowledge that they have the rights to the code they're contributing by signing their commits in git using a "DCO Sign Off". Note that this is different to "commit signing" using something like PGP or gitsign!

Any copyright notices in a cert-manager repo should specify the authors as "The cert-manager Authors".

To sign your work, pass the --signoff option to git commit or git rebase:

# Sign off a commit as you're making it
git commit --signoff -m"my commit"

# Add a signoff to the last commit you made
git commit --amend --signoff

# Rebase your branch against master and sign off every commit in your branch
git rebase --signoff master

This will add a line similar to the following at the end of your commit:

Signed-off-by: Joe Bloggs <joe@example.com>

By signing off a commit you're stating that you certify the following:
