# Contributing to the reference library
## Community help
If you need help, please ask in the [#distribution](https://cloud-native.slack.com/archives/C01GVR8SY4R) channel on CNCF community slack.
[Click here for an invite to the CNCF community slack](https://slack.cncf.io/)
## Reporting security issues
The maintainers take security seriously. If you discover a security
issue, please bring it to their attention right away!
Please **DO NOT** file a public issue, instead send your report privately to
[cncf-distribution-security@lists.cncf.io](mailto:cncf-distribution-security@lists.cncf.io).
## Reporting an issue properly
By following these simple rules you will get better and faster feedback on your issue.
- search the bugtracker for an already reported issue
### If you found an issue that describes your problem:
- please read other user comments first, and confirm this is the same issue: a given error condition might be indicative of different problems - you may also find a workaround in the comments
- please refrain from adding "same thing here" or "+1" comments
- you don't need to comment on an issue to get notified of updates: just hit the "subscribe" button
- comment if you have some new, technical and relevant information to add to the case
- __DO NOT__ comment on closed issues or merged PRs. If you think you have a related problem, open up a new issue and reference the PR or issue.
### If you have not found an existing issue that describes your problem:
1. create a new issue, with a succinct title that describes your issue:
- bad title: "It doesn't work with my docker"
- good title: "Private registry push fail: 400 error with E_INVALID_DIGEST"
2. copy the output of (or similar for other container tools):
- `docker version`
- `docker info`
- `docker exec <registry-container> registry --version`
3. copy the command line you used to launch your Registry
4. restart your docker daemon in debug mode (add `-D` to the daemon launch arguments)
5. reproduce your problem and get your docker daemon logs showing the error
6. if relevant, copy your registry logs that show the error
7. provide any relevant detail about your specific Registry configuration (e.g., storage backend used)
8. indicate if you are using an enterprise proxy, Nginx, or anything else between you and your Registry
## Contributing Code
Contributions should be made via pull requests. Pull requests will be reviewed
by one or more maintainers or reviewers and merged when acceptable.
You should follow the basic GitHub workflow:
1. Use your own [fork](https://help.github.com/en/articles/about-forks)
2. Create your [change](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#successful-changes)
3. Test your code
4. [Commit](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#commit-messages) your work, always [sign your commits](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#commit-messages)
5. Push your change to your fork and create a [Pull Request](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request-from-a-fork)
Refer to [containerd's contribution guide](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#successful-changes)
for tips on creating a successful contribution.
## Sign your work
The sign-off is a simple line at the end of the explanation for the patch. Your
signature certifies that you wrote the patch 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](http://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
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
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.smith@email.com>
Use your real name (sorry, no pseudonyms or anonymous contributions.)
If you set your `user.name` and `user.email` git configs, you can sign your
commit automatically with `git commit -s`.

# distribution/reference Project Governance
Distribution [Code of Conduct](./CODE-OF-CONDUCT.md) can be found here.
For specific guidance on practical contribution steps please
see our [CONTRIBUTING.md](./CONTRIBUTING.md) guide.
## Maintainership
There are different types of maintainers, with different responsibilities, but
all maintainers have 3 things in common:
1) They share responsibility in the project's success.
2) They have made a long-term, recurring time investment to improve the project.
3) They spend that time doing whatever needs to be done, not necessarily what
is the most interesting or fun.
Maintainers are often under-appreciated, because their work is harder to appreciate.
It's easy to appreciate a really cool and technically advanced feature. It's harder
to appreciate the absence of bugs, the slow but steady improvement in stability,
or the reliability of a release process. But those things distinguish a good
project from a great one.
## Reviewers
A reviewer is a core role within the project.
They share in reviewing issues and pull requests and their LGTM counts towards the
required LGTM count to merge a code change into the project.
Reviewers are part of the organization but do not have write access.
Becoming a reviewer is a core aspect in the journey to becoming a maintainer.
## Adding maintainers
Maintainers are first and foremost contributors that have shown they are
committed to the long term success of a project. Contributors wanting to become
maintainers are expected to be deeply involved in contributing code, pull
request review, and triage of issues in the project for more than three months.
Just contributing does not make you a maintainer, it is about building trust
with the current maintainers of the project and being a person that they can
depend on and trust to make decisions in the best interest of the project.
Periodically, the existing maintainers curate a list of contributors that have
shown regular activity on the project over the prior months. From this list,
maintainer candidates are selected and proposed in a pull request or a
maintainers communication channel.
After a candidate has been announced to the maintainers, the existing
maintainers are given five business days to discuss the candidate, raise
objections and cast their vote. Votes may take place on the communication
channel or via pull request comment. Candidates must be approved by at least 66%
of the current maintainers by adding their vote on the mailing list. The
reviewer role has the same process but only requires 33% of current maintainers.
Only maintainers of the repository that the candidate is proposed for are
allowed to vote.
If a candidate is approved, a maintainer will contact the candidate to invite
the candidate to open a pull request that adds the contributor to the
MAINTAINERS file. The voting process may take place inside a pull request if a
maintainer has already discussed the candidacy with the candidate and a
maintainer is willing to be a sponsor by opening the pull request. The candidate
becomes a maintainer once the pull request is merged.
## Stepping down policy
Life priorities, interests, and passions can change. If you're a maintainer but
feel you must remove yourself from the list, inform other maintainers that you
intend to step down, and if possible, help find someone to pick up your work.
At the very least, ensure your work can be continued where you left off.
After you've informed other maintainers, create a pull request to remove
yourself from the MAINTAINERS file.
## Removal of inactive maintainers
Similar to the procedure for adding new maintainers, existing maintainers can
be removed from the list if they do not show significant activity on the
project. Periodically, the maintainers review the list of maintainers and their
activity over the last three months.
If a maintainer has shown insufficient activity over this period, a neutral
person will contact the maintainer to ask if they want to continue being
a maintainer. If the maintainer decides to step down as a maintainer, they
open a pull request to be removed from the MAINTAINERS file.
If the maintainer wants to remain a maintainer, but is unable to perform the
required duties they can be removed with a vote of at least 66% of the current
maintainers. In this case, maintainers should first propose the change to
maintainers via the maintainers communication channel, then open a pull request
for voting. The voting period is five business days. The voting pull request
should not come as a surpise to any maintainer and any discussion related to
performance must not be discussed on the pull request.
## How are decisions made?
Docker distribution is an open-source project with an open design philosophy.
This means that the repository is the source of truth for EVERY aspect of the
project, including its philosophy, design, road map, and APIs. *If it's part of
the project, it's in the repo. If it's in the repo, it's part of the project.*
As a result, all decisions can be expressed as changes to the repository. An
implementation change is a change to the source code. An API change is a change
to the API specification. A philosophy change is a change to the philosophy
manifesto, and so on.
All decisions affecting distribution, big and small, follow the same 3 steps:
* Step 1: Open a pull request. Anyone can do this.
* Step 2: Discuss the pull request. Anyone can do this.
* Step 3: Merge or refuse the pull request. Who does this depends on the nature
of the pull request and which areas of the project it affects.
## Helping contributors with the DCO
The [DCO or `Sign your work`](./CONTRIBUTING.md#sign-your-work)
requirement is not intended as a roadblock or speed bump.
Some contributors are not as familiar with `git`, or have used a web
based editor, and thus asking them to `git commit --amend -s` is not the best
way forward.
In this case, maintainers can update the commits based on clause (c) of the DCO.
The most trivial way for a contributor to allow the maintainer to do this, is to
add a DCO signature in a pull requests's comment, or a maintainer can simply
note that the change is sufficiently trivial that it does not substantially
change the existing contribution - i.e., a spelling change.
When you add someone's DCO, please also add your own to keep a log.
## I'm a maintainer. Should I make pull requests too?
Yes. Nobody should ever push to master directly. All changes should be
made through a pull request.
## Conflict Resolution
If you have a technical dispute that you feel has reached an impasse with a
subset of the community, any contributor may open an issue, specifically
calling for a resolution vote of the current core maintainers to resolve the
dispute. The same voting quorums required (2/3) for adding and removing
maintainers will apply to conflict resolution.
