Security Embargo Policy
Some information about releases is subject to embargo and we have defined policy about how those embargoes are set. Please refer to the Security Embargo Policy for more information.
NOTE: The Patch Release Team and Branch Manager handbooks will be de-duplicated at a later date.
Note: The documentation might refer to the Patch Release Team and the Branch Management role. Those two roles were consolidated into the Release Managers role.
Minimum requirements for Release Managers and Release Manager Associates are:
- Familiarity with basic Unix commands and able to debug shell scripts.
- Familiarity with branched source code workflows via
gitcommand line invocations.
- General knowledge of Google Cloud (Cloud Build and Cloud Storage).
- Open to seeking help and communicating clearly.
- Kubernetes Community membership
Release Managers are responsible for:
- Coordinating and cutting Kubernetes releases:
- Maintaining the release branches:
- Reviewing cherry picks
- Ensuring the release branch stays healthy and that no unintended patch gets merged
- Mentoring the Release Manager Associates group
- Actively developing features and maintaining the code in k/release
- Supporting Release Manager Associates and contributors through actively
participating in the Buddy program
- Check in monthly with Associates and delegate tasks, empower them to cut releases, and mentor
- Being available to support Associates in onboarding new contributors e.g., answering questions and suggesting appropriate work for them to do

Becoming a Release Manager
To become a Release Manager, one must first serve as a Release Manager Associate. Associates graduate to Release Manager by actively working on releases over several cycles and:
- demonstrating the willingness to lead
- tag-teaming with Release Managers on patches, to eventually cut a release
- because releases have a limiting function, we also consider substantial contributions to image promotion and other core Release Engineering tasks
- questioning how Associates work, suggesting improvements, gathering feedback, and driving change
- being reliable and responsive
- leaning into advanced work that requires Release Manager-level access and privileges to complete
Release Manager Associates
Release Manager Associates are apprentices to the Release Managers, formerly referred to as Release Manager shadows. They are responsible for:
- Patch release work, cherry pick review
- Contributing to k/release: updating dependencies and getting used to the source codebase
- Contributing to the documentation: maintaining the handbooks, ensuring that release processes are documented
- With help from a release manager: working with the Release Team during the release cycle and cutting Kubernetes releases
- Seeking opportunities to help with prioritization and communication
- Sending out pre-announcements and updates about patch releases
- Updating the calendar, helping with the release dates and milestones from the release cycle timeline
- Through the Buddy program, onboarding new contributors and pairing up with them on tasks

Becoming a Release Manager Associate
Contributors can become Associates by demonstrating the following:
- consistent participation, including 6-12 months of active release engineering-related work
- experience fulfilling a technical lead role on the Release Team during a
- this experience provides a solid baseline for understanding how SIG Release works overall—including our expectations regarding technical skills, communications/responsiveness, and reliability
- working on k/release items that improve our interactions with Testgrid,
cleaning up libraries, etc.
- these efforts require interacting and pairing with Release Managers and Associates
Build Admins are (currently) Google employees with the requisite access to Google build systems/tooling to publish deb/rpm packages on behalf of the Kubernetes project. They are responsible for:
- Building, signing, and publishing the deb/rpm packages
- Being the interlock with Release Managers (and Associates) on the final steps of each minor (1.Y) and patch (1.Y.Z) release

SIG Release Leads
SIG Release Chairs and Technical Leads are responsible for:
- The governance of SIG Release
- Leading knowledge exchange sessions for Release Managers and Associates
- Coaching on leadership and prioritization
They are mentioned explicitly here as they are owners of the various communications channels and permissions groups (GitHub teams, GCP access) for each role. As such, they are highly privileged community members and privy to some private communications, which can at times relate to Kubernetes security disclosures.
