This document outlines a structure for creating and associating code repositories with the Knative project. It also describes how and when repositories are removed.
Core repositories are considered core components of Knative. They are utilities, tools, applications, or libraries that form or support the foundation of the project.
Core repositories are all those located under the github.com/knative organization.
- Repository must live under github.com/knative/project-name.
- Must adopt the Knative Code of Conduct.
- All code projects must use the Apache License version 2.0.
- Documentation repositories must use Creative Commons License version 4.0.
- All OWNERS must be members of the Knative community.
- Repository creation must be approved by the Technical Oversight Committee.
The Technical Oversight Committee may allow repositories to be donated to the Knative project. In addition to meeting the core repository requirements, donated repositories must:
- Adopt the Google CLA bot.
- All contributors to the donated repository must have signed the Google CLA.
- All code must adopt the standard Knative header, attributing copyright as
follows:
"Copyright <year> The Knative Authors"
. - Additions of the standard Knative header to code created by the contributors can occur post-transfer, but should ideally occur shortly thereafter.
- An
AUTHORS
file should be created in the repo root, if one does not already exist, that includes the original authors of the code. See knative/serving AUTHORS for reference.- Note that copyright notices should only be modified or removed by the people or organizations named in the notice.
As important as it is to add new repositories, it is equally important to prune repositories when necessary. See Grounds for removal.
It is important to the success of Knative that all Knative repositories stay active, healthy, and aligned with the scope and mission of project.
Core repositories may be removed from the project if they are deemed inactive. Inactive repositories are those that meet any of the following criteria:
- There are no longer any active maintainers for the project, and no replacements can be found.
- All PRs and issues have gone un-addressed for longer than six months.
- There have been no new commits or other changes in more than a year.
- The contents have been folded into another actively maintained project.
When a repository has been deemed eligible for removal, we take the following steps:
- A proposal to remove the repository is brought to the attention of the
Technical Oversight Committee through a GitHub issue posted in the
community repo.
- Feedback is encouraged during a Steering Committee meeting before any action is taken.
- Once the Steering Committee has approved of the removal, if the repo is not moving to another
actively maintained project:
- The repo description is edited to start with the phrase "[EOL]"
- All open issues and PRs are closed
- All external collaborates are removed
- All webhooks, apps, integrations, or services are removed
- GitHub pages are disabled
- The repo is marked as archived using GitHub's archive feature
- The removal is announced on the knative-dev mailing list
- Documentation is removed / updated as appropriate from the knative/docs website
This procedure maintains the complete record of issues, PRs, and other contributions. It leaves the repository read-only and makes it clear that the repository is retired and no longer maintained.
It is beneficial for Knative working groups to be able to own code outside the
core knative
organization, which is kept intentionally small and has a high
bar for entry. The knative-extensions
GitHub organization was created for this
purpose. Repositories in knative-extensions
are intended to give working groups
more latitude to experiment with new ideas and to self-organize and manage
contributions which may be important to the project but which do not need the
level of governance of the core project.
Note that knative-extensions
is not an incubation area for projects entering
the knative
github org; in most cases, projects in the extensions will remain
there for the entire duration. knative-extensions
also provides a location for
implementations of core interfaces which do not themselves need to be part of
every knative installation, such as networking or eventing integrations. In the
event that a working group wants a project in extensions to be considered for
transfer to the knative
org, the request will be considered on a case-by-case
basis by joint decision of the Steering Committee and the Technical Oversight
Committee.
Note: prior art here from the Kubernetes community.
Working groups are allowed to request repositories that meet the following requirements. The Steering Committee will maintain the process and perform the repository creation steps to ensure that the following requirements have been met:
-
Vendor dependencies must be clearly called out, and participation must be open to the community.
-
If the repository is for integration with a specific technology vendor, affiliation with that vendor must not be required for participation.
-
Non-integration repositories should aim to avoid dependencies on vendor-specific technology by publishing abstract interfaces which can be implemented by multiple vendors. Those implementations are not required to live in separate repositories.
-
-
Must adopt the Knative CLA.
-
Must adopt the Knative code of conduct.
-
Must adopt the Apache 2.0 license.
-
Must be sponsored by a specific working group, which should be designated in the
README.md
for the repo. In addition, at least one WG lead must be in the root-level OWNERS file. -
Copyright assigned to The Knative Authors.
-
Document clear release and install processes.
-
Clearly document the stability and API guarantees (both in the top-level
README.md
and by using appropriate API versioning for Kubernetes apigroups).- The Steering Committee will maintain a template which will be used during the creation of
new repositories. Existing repositiories are encouraged to update their
README
s from time to time as the format changes.
- The Steering Committee will maintain a template which will be used during the creation of
new repositories. Existing repositiories are encouraged to update their
-
Kubernetes APIs must be homed in a valid group with a DNS prefix approved by the Steering Committee.
-
APIs under
knative.dev
should:-
Be under a subdomain managed by the owning Working Group (e.g.
sources.knative.dev
, notknative.dev
). The Steering Committee is considered the authority for assigning subdomains to working groups. -
Coordinate with the Working Group in API naming to avoid collisions or confusing naming. This also includes API review by the responsible Working Group to ensure consistency and alignment with duck-type field naming.
-
-
Working groups must designate the repositories they own (by prefix or in the README.md of the repo, at a minimum).
Repositories owned by working groups are encouraged to embrace the project value of pluggability.
The following are not required to create a working-group-owned repository:
- Steering approval (see "the fine print")
- Steering Committee approval
- Steering Committee may request certain naming patterns (e.g.
kn-plugin
for client WG)
- Steering Committee may request certain naming patterns (e.g.
- Solving an unique problem (exploring different approaches to problems outside the core is actively encouraged!)
Steering reserve the right to require that repos be removed or
transferred out of the knative-extensions
organization and API groups to be
renamed. This is intended to simplify the process in the common case, while
giving Steering the ability to step in and rectify problems that
may arise.
Working groups are responsible for the upkeep of their repositories and are
expected to keep a high quality bar. Inactive or non-conforming repositories
should be archived, deleted, or moved out of the knative-extensions
organization,
following the general Procedure for Removal for
repositories.
CLOMonitor is a CNCF tool that periodically checks open source projects repositories to verify they meet certain project health best practices.
CLOTributor is a CNCF tool that makes it easier to discover great opportunities to become a Cloud Native contributor.
When a new repository is created, consider adding it to CLOMonitor data file, similar to:
- name: eventing
url: https://github.com/knative/eventing
check_sets:
- code-lite
This will make the repository will be listed in CLOMonitor's Knative project health report. It will also make CLOTributor to list good-first-issue
s of the new repository.
If you would like to exclude the repository from the health report but have the good-first-issues
in CLOTributor, add following the field:
exclude:
- clomonitor
Based on the maturity of the repository, it is possible to use different check_sets
. See CLOMonitor's checks documentation for more information.
