Contributing to Epinio

Epinio welcomes your participation in the project. Epinio accepts contributions via GitHub issues and pull requests. This document outlines what you need to make a successful contribution to the project.

Start with an issue

Before creating a pull request, check the issues. Is the topic already live, are there any linked pull requests? This is especially true if the change request is something large. You can discuss the bug, feature request, or other type of issue with the team and others. Lastly, create an issue, and perhaps a pull request, if needed. This helps define common goals and reduces duplication of effort.

Sign your commits

A sign-off is a line at the end of the explanation for a commit. You must sign all your commits. Your signature certifies that you wrote the patch or otherwise have the right to contribute the material. When signing-off you agree to the following rules (from

Developer Certificate of Origin
Version 1.1

Copyright (C) 2004, 2006 The Linux Foundation and its contributors.

Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.

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

(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 add a line to every git commit message:

Signed-off-by: Joe Smith <>

You should use your real name (no pseudonyms or anonymous contributions please).

If you set your and in your local git configuration, you can sign your commit automatically with git commit -s.


If your git config information is correctly set then viewing the git log information for your commit looks something like this:

Author: John Smith <>
Date: Thu Feb 2 11:41:15 2023 -0800
Signed-off-by: John Smith <>

The Author and Signed-off-by lines match. If not, the Developer Certificate of Origin (DCO) check rejects the pull request.

Pull requests

Pull requests for a code change should reference the issue they're for. This enables issues to serve as a central point of reference for a change. For example, if a pull request fixes or completes an issue, the commit or pull request should include something like:

Closes #123

This indicates that the PR closes issue #123 when merged.

Semantic versioning

Epinio follows semantic versioning.

This doesn't cover other tools included in Epinio. Kubernetes has its own release versioning scheme that's similar to SemVer but semantically different.

Coding style

Epinio expects Go code formatted with go fmt.
