We welcome contributions from the community. Here are some guidelines.
- Fork the repo.
- Before commiting any code, install the pre-commits by:
make precommit_install
# Example usage if you want to run it manually
pre-commit run # Run against staged changes
pre-commit run -a # Run against all files
- Pre-commits will automatically format your code at commit time.
- Create your PR.
- Tests will automatically run for you.
- When all of the tests are passing, tag @envoyproxy/ratelimit-maintainers and we will review it and merge.
- Party time.
The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: if you can certify the below (from developercertificate.org):
Developer Certificate of Origin
Version 1.1
Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
660 York Street, Suite 102,
San Francisco, CA 94110 USA
Everyone is permitted to copy and distribute verbatim copies of this

Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
then you just add a line to every git commit message:
Signed-off-by: Joe Smith <joe@gmail.com>
using your real name (sorry, no pseudonyms or anonymous contributions.)
You can add the sign off when creating the git commit via git commit -s
.
If you want this to be automatic you can set up some aliases:
git config --add alias.amend "commit -s --amend"
git config --add alias.c "commit -s"
If your PR fails the DCO check, it's necessary to fix the entire commit history in the PR. Best practice is to squash the commit history to a single commit, append the DCO sign-off as described above, and force push. For example, if you have 2 commits in your history:
git rebase -i HEAD^^
(interactive squash + DCO append)
git push origin -f
Note, that in general rewriting history in this way is a hindrance to the review process and this should only be done to correct a DCO mistake.
