Kubernetes - Community Proposals

Introduction

Kubernetes is a community-driven project, and many of its enhancements and new features are proposed and developed by the community. This guide provides an intermediate-level overview of community proposals for Kubernetes enhancements, including how proposals are made, reviewed, and implemented.

Kubernetes Enhancement Proposals (KEPs)

Kubernetes Enhancement Proposals (KEPs) are the primary mechanism for proposing significant changes or new features to Kubernetes. Here’s an overview of the KEP process:

• Proposal Creation: A community member drafts a KEP document outlining the proposed change, its rationale, design details, and potential impact.
• Initial Review: The draft KEP is submitted for initial review by the relevant Special Interest Group (SIG). Feedback is provided, and the proposal is refined accordingly.
• Community Feedback: The refined KEP is shared with the broader community for feedback and discussion.
• Approval: Once the proposal has been reviewed and revised, it is formally approved by the SIG and added to the list of accepted KEPs.
• Implementation: The approved KEP is implemented, tested, and integrated into a future Kubernetes release.

Key Community Proposals

Several key proposals have significantly impacted Kubernetes development. Here are a few notable KEPs:

• KEP-900: Server-Side Apply: Enhances the Kubernetes API to support server-side apply, enabling more efficient and reliable resource management. Learn more.
• KEP-152: Topology Manager: Introduces the Topology Manager to improve CPU and device affinity for pods, enhancing performance for high-demand workloads. Learn more.
• KEP-688: Windows Container Support: Expands Kubernetes support for Windows containers, enabling a broader range of applications to run on Kubernetes. Learn more.
• KEP-277: Ephemeral Containers: Adds support for ephemeral containers, allowing temporary containers to be attached to running pods for debugging and troubleshooting. Learn more.
• KEP-1855: Immutable Secrets and ConfigMaps: Introduces immutable Secrets and ConfigMaps to enhance security and stability by preventing changes to these resources. Learn more.

Getting Involved

Community involvement is crucial to the success of Kubernetes. Here are some ways you can get involved in the proposal process:

• Join a SIG: Special Interest Groups (SIGs) focus on specific areas of the project. Join a SIG that aligns with your interests to participate in discussions and contribute to proposals.
• Review KEPs: Review and provide feedback on existing KEPs. Your insights and suggestions can help refine proposals and ensure they meet community needs.
• Submit a KEP: If you have an idea for an enhancement or new feature, draft and submit a KEP. Follow the KEP process and collaborate with the community to bring your proposal to fruition.
• Participate in Discussions: Engage in community discussions on forums, mailing lists, and SIG meetings to stay informed and contribute to the evolution of Kubernetes.
