Welcome! We are very happy to accept community contributions to the project, whether through filing issues or code in the form of Pull Requests. Please note that by participating in this project, you agree to abide by the Code of Conduct, as well as the terms of the Developer Certificate of Origin.
Before opening any new issues, please search our existing GitHub issues to check if your bug or suggestion has already been filed. If such an issue already exists, we recommend adding your comments and perspective to that existing issue instead.
When opening an issue, please select the most appropriate template for what you're contributing:
- Bug Report: If you would like to report the project or tool behaving in unexpected ways.
- Documentation Improvement: If you have corrections or improvements to the project's documents, be they typos, factual errors, or missing content.
- Request: If you have a feature request, suggestion, or a even a design proposal to review.
- Question: If you would like to ask the maintainers a question about the project.
If you would like to report a security vulnerability, please follow the instructions for reporting security issues instead.
Follow the instructions to set up your dev environment to build Copacetic.
For an overview of the project components, refer to the Copa design document.
Copacetic is written in Go, so any IDE that supports Go may be used. If you have an IDE you prefer, simply search for a guide to set it up with Go. If you don't have a preferred IDE or if you're a new developer, some popular options are listed below:
After choosing your IDE, we should install gofumpt. It's a stricter formatter than gofmt which Copacetic requires to pass all tests. Once installed, you may optionally set it up to run in your IDE of choice by following the instructions about halfway down the page.
Copacetic requires Docker for patching images. To install Docker, follow the Docker installation guide.
Once you can successfully make the project, any code contributions should also successfully:
- Pass unit tests via
make test. - Lint cleanly via
make lint. - Be formatted with
gofumpt.
Pull requests will also be expected to pass the PR functional tests specified by .github/workflows/build.yml.
If you'd like to start contributing code to the project, you can search for issues with the good first issue label. Other kinds of PR contributions we would look for include:
- Fixes for bugs and other correctness issues.
- Docs and other content improvements (e.g. samples).
- Extensions to support parsing new scanning report formats.
- Extensions to support patching images based on new distros or using new package managers.
For any changes that may involve significant refactoring or development effort, we suggest that you file an issue to discuss the proposal with the maintainers first as it is unlikely that we will accept large PRs without prior discussion that have:
- Architectural changes (e.g. breaking interfaces or violations of this project's design tenets).
- Unsolicited features that significantly expand the functional scope of the tool.
Pull requests should be submitted from your fork of the project with the PR template filled out. This project uses the Angular commit message format for automated changelog generation, so it's helpful to be familiar with it as the maintainers will need to ensure adherence to it on accepting PRs.
We suggest:
- Use the standard header format of
"<type>: <short summary>"where the<type>is one of the following:- build: Changes that affect the build system or external dependencies
- ci: Changes to the GitHub workflows and configurations
- docs: Documentation only changes
- feat: A new feature
- fix: A bug fix
- perf: A code change that improves performance
- refactor: A code change that neither fixes a bug nor adds a feature
- test: Adding missing tests or correcting existing tests
- Use a concise, imperative description of the changes included in the
<short summary>of the header, the body of the PR, and generally in your commit messages. - Use GitHub keywords in the footer of your PR description, such as
closesto automatically close issues the PR intends to address.
The Developer Certificate of Origin (DCO) is a lightweight way for contributors to certify that they wrote or otherwise have the right to submit the code they are contributing to the project. Here is the full text of the DCO, reformatted for readability:
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.
Contributors sign-off that they adhere to these requirements by adding a Signed-off-by line to commit messages.
This is my commit message
Signed-off-by: Random J Developer <random@developer.example.org>
Git even has a -s command line option to append this automatically to your commit message:
git commit -s -m 'This is my commit message'Pull requests that do not contain a valid Signed-off-by line cannot be merged.
No worries - You can easily amend your commit with a sign-off and force push the change to your submitting branch:
git switch <branch-name>
git commit --amend --no-edit --signoff
git push --force-with-lease <remote-name> <branch-name>This project has adopted the CNCF Code of Conduct
