Awesome! We have a contributor's guide that explains +[setting up a Docker development environment and the contribution +process](https://docs.docker.com/opensource/project/who-written-for/). + +This page contains information about reporting issues as well as some tips and +guidelines useful to experienced open source contributors. Finally, make sure +you read our [community guidelines](#docker-community-guidelines) before you +start participating. + +## Topics + +* [Reporting Security Issues](#reporting-security-issues) +* [Design and Cleanup Proposals](#design-and-cleanup-proposals) +* [Reporting Issues](#reporting-other-issues) +* [Quick Contribution Tips and Guidelines](#quick-contribution-tips-and-guidelines) +* [Community Guidelines](#docker-community-guidelines) + +## Reporting security issues + +The Docker 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 +[security@docker.com](mailto:security@docker.com). + +Security reports are greatly appreciated and we will publicly thank you for it. +We also like to send gifts—if you're into Docker schwag, make sure to let +us know. We currently do not offer a paid security bounty program, but are not +ruling it out in the future. + + +## Reporting other issues + +A great way to contribute to the project is to send a detailed report when you +encounter an issue. We always appreciate a well-written, thorough bug report, +and will thank you for it! + +Check that [our issue database](https://github.com/docker/cli/issues) +doesn't already include that problem or suggestion before submitting an issue. +If you find a match, you can use the "subscribe" button to get notified on +updates. Do *not* leave random "+1" or "I have this too" comments, as they +only clutter the discussion, and don't help resolving it. However, if you +have ways to reproduce the issue or have additional information that may help +resolving the issue, please leave a comment. + +When reporting issues, always include: + +* The output of `docker version`. +* The output of `docker info`. + +Also include the steps required to reproduce the problem if possible and +applicable. This information will help us review and fix your issue faster. +When sending lengthy log-files, consider posting them as a gist (https://gist.github.com). +Don't forget to remove sensitive data from your logfiles before posting (you can +replace those parts with "REDACTED"). + +## Quick contribution tips and guidelines + +This section gives the experienced contributor some tips and guidelines. + +### Pull requests are always welcome + +Not sure if that typo is worth a pull request? Found a bug and know how to fix +it? Do it! We will appreciate it. Any significant improvement should be +documented as [a GitHub issue](https://github.com/docker/cli/issues) before +anybody starts working on it. + +We are always thrilled to receive pull requests. We do our best to process them +quickly. If your pull request is not accepted on the first try, +don't get discouraged! Our contributor's guide explains [the review process we +use for simple changes](https://docs.docker.com/opensource/workflow/make-a-contribution/). + +### Talking to other Docker users and contributors + + + + + + + + + + + + + + + + + + + + +
Forums + A public forum for users to discuss questions and explore current design patterns and + best practices about Docker and related projects in the Docker Ecosystem. To participate, + just log in with your Docker Hub account on https://forums.docker.com. +
Community Slack + The Docker Community has a dedicated Slack chat to discuss features and issues. You can sign-up with this link. +
Twitter + You can follow Docker's Twitter feed + to get updates on our products. You can also tweet us questions or just + share blogs or stories. +
Stack Overflow + Stack Overflow has over 17000 Docker questions listed. We regularly + monitor Docker questions + and so do many other knowledgeable Docker users. +
+ + +### Conventions + +Fork the repository and make changes on your fork in a feature branch: + +- If it's a bug fix branch, name it XXXX-something where XXXX is the number of + the issue. +- If it's a feature branch, create an enhancement issue to announce + your intentions, and name it XXXX-something where XXXX is the number of the + issue. + +Submit unit tests for your changes. Go has a great test framework built in; use +it! Take a look at existing tests for inspiration. [Run the full test +suite](README.md) on your branch before +submitting a pull request. + +Update the documentation when creating or modifying features. Test your +documentation changes for clarity, concision, and correctness, as well as a +clean documentation build. See our contributors guide for [our style +guide](https://docs.docker.com/opensource/doc-style) and instructions on [building +the documentation](https://docs.docker.com/opensource/project/test-and-docs/#build-and-test-the-documentation). + +Write clean code. Universally formatted code promotes ease of writing, reading, +and maintenance. Always run `gofmt -s -w file.go` on each changed file before +committing your changes. Most editors have plug-ins that do this automatically. + +Pull request descriptions should be as clear as possible and include a reference +to all the issues that they address. + +Commit messages must start with a capitalized and short summary (max. 50 chars) +written in the imperative, followed by an optional, more detailed explanatory +text which is separated from the summary by an empty line. + +Code review comments may be added to your pull request. Discuss, then make the +suggested modifications and push additional commits to your feature branch. Post +a comment after pushing. New commits show up in the pull request automatically, +but the reviewers are notified only when you comment. + +Pull requests must be cleanly rebased on top of master without multiple branches +mixed into the PR. + +**Git tip**: If your PR no longer merges cleanly, use `rebase master` in your +feature branch to update your pull request rather than `merge master`. + +Before you make a pull request, squash your commits into logical units of work +using `git rebase -i` and `git push -f`. A logical unit of work is a consistent +set of patches that should be reviewed together: for example, upgrading the +version of a vendored dependency and taking advantage of its now available new +feature constitute two separate units of work. Implementing a new function and +calling it in another file constitute a single logical unit of work. The very +high majority of submissions should have a single commit, so if in doubt: squash +down to one. + +After every commit, make sure the test suite passes. Include documentation +changes in the same pull request so that a revert would remove all traces of +the feature or fix. + +Include an issue reference like `Closes #XXXX` or `Fixes #XXXX` in the pull request +description that close an issue. Including references automatically closes the issue +on a merge. + +Please do not add yourself to the `AUTHORS` file, as it is regenerated regularly +from the Git history. + +Please see the [Coding Style](#coding-style) for further guidelines. + +### Merge approval + +Docker maintainers use LGTM (Looks Good To Me) in comments on the code review to +indicate acceptance. + +A change requires LGTMs from an absolute majority of the maintainers of each +component affected. For example, if a change affects `docs/` and `registry/`, it +needs an absolute majority from the maintainers of `docs/` AND, separately, an +absolute majority of the maintainers of `registry/`. + +For more details, see the [MAINTAINERS](MAINTAINERS) page. + +### 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 + +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`. + +### How can I become a maintainer? + +The procedures for adding new maintainers are explained in the +global [MAINTAINERS](https://github.com/docker/opensource/blob/master/MAINTAINERS) +file in the [https://github.com/docker/opensource/](https://github.com/docker/opensource/) +repository. + +Don't forget: being a maintainer is a time investment. Make sure you +will have time to make yourself available. You don't have to be a +maintainer to make a difference on the project! + +## Docker community guidelines + +We want to keep the Docker community awesome, growing and collaborative. We need +your help to keep it that way. To help with this we've come up with some general +guidelines for the community as a whole: + +* Be nice: Be courteous, respectful and polite to fellow community members: + no regional, racial, gender, or other abuse will be tolerated. We like + nice people way better than mean ones! + +* Encourage diversity and participation: Make everyone in our community feel + welcome, regardless of their background and the extent of their + contributions, and do everything possible to encourage participation in + our community. + +* Keep it legal: Basically, don't get us in trouble. Share only content that + you own, do not share private or sensitive information, and don't break + the law. + +* Stay on topic: Make sure that you are posting to the correct channel and + avoid off-topic discussions. Remember when you update an issue or respond + to an email you are potentially sending to a large number of people. Please + consider this before you update. Also remember that nobody likes spam. + +* Don't send email to the maintainers: There's no need to send email to the + maintainers to ask them to investigate an issue or to take a look at a + pull request. Instead of sending an email, GitHub mentions should be + used to ping maintainers to review a pull request, a proposal or an + issue. + +### Guideline violations — 3 strikes method + +The point of this section is not to find opportunities to punish people, but we +do need a fair way to deal with people who are making our community suck. + +1. First occurrence: We'll give you a friendly, but public reminder that the + behavior is inappropriate according to our guidelines. + +2. Second occurrence: We will send you a private message with a warning that + any additional violations will result in removal from the community. + +3. Third occurrence: Depending on the violation, we may need to delete or ban + your account. + +**Notes:** + +* Obvious spammers are banned on first occurrence. If we don't do this, we'll + have spam all over the place. + +* Violations are forgiven after 6 months of good behavior, and we won't hold a + grudge. + +* People who commit minor infractions will get some education, rather than + hammering them in the 3 strikes process. + +* The rules apply equally to everyone in the community, no matter how much + you've contributed. + +* Extreme violations of a threatening, abusive, destructive or illegal nature + will be addressed immediately and are not subject to 3 strikes or forgiveness. + +* Contact abuse@docker.com to report abuse or appeal violations. In the case of + appeals, we know that mistakes happen, and we'll work with you to come up with a + fair solution if there has been a misunderstanding. + +## Coding Style + +Unless explicitly stated, we follow all coding guidelines from the Go +community. While some of these standards may seem arbitrary, they somehow seem +to result in a solid, consistent codebase. + +It is possible that the code base does not currently comply with these +guidelines. We are not looking for a massive PR that fixes this, since that +goes against the spirit of the guidelines. All new contributions should make a +best effort to clean up and make the code base better than they left it. +Obviously, apply your best judgement. Remember, the goal here is to make the +code base easier for humans to navigate and understand. Always keep that in +mind when nudging others to comply. + +The rules: + +1. All code should be formatted with `gofmt -s`. +2. All code should pass the default levels of + [`golint`](https://github.com/golang/lint). +3. All code should follow the guidelines covered in [Effective + Go](http://golang.org/doc/effective_go.html) and [Go Code Review + Comments](https://github.com/golang/go/wiki/CodeReviewComments). +4. Comment the code. Tell us the why, the history and the context. +5. Document _all_ declarations and methods, even private ones. Declare + expectations, caveats and anything else that may be important. If a type + gets exported, having the comments already there will ensure it's ready. +6. Variable name length should be proportional to its context and no longer. + `noCommaALongVariableNameLikeThisIsNotMoreClearWhenASimpleCommentWouldDo`. + In practice, short methods will have short variable names and globals will + have longer names. +7. No underscores in package names. If you need a compound name, step back, + and re-examine why you need a compound name. If you still think you need a + compound name, lose the underscore. +8. No utils or helpers packages. If a function is not general enough to + warrant its own package, it has not been written generally enough to be a + part of a util package. Just leave it unexported and well-documented. +9. All tests should run with `go test` and outside tooling should not be + required. No, we don't need another unit testing framework. Assertion + packages are acceptable if they provide _real_ incremental value. +10. Even though we call these "rules" above, they are actually just + guidelines. Since you've read all the rules, you now know that. + +If you are having trouble getting into the mood of idiomatic Go, we recommend +reading through [Effective Go](https://golang.org/doc/effective_go.html). The +[Go Blog](https://blog.golang.org) is also a great resource. Drinking the +kool-aid is a lot easier than going thirsty. \ No newline at end of file
