Hotfix Release Pipeline

KEEP is the core B2B R&D efficiency and observability platform within Kuaishou. This project focuses on a critical module within the KEEP platform: the Hotfix Release (internally known as Security Cushion). It is an automated emergency hotfix and protection system targeting online application crashes and abnormal stack traces.

Secure Release Pipeline

Generation & Allowlist Validation

Human-in-the-Loop Review

Instead of full automation, this step acts as a crucial safety gate. It allows developers to quickly scan the auto-generated Hotfix Artifact JSON before granting final approval, preventing systemic errors.

Controlled Allowlist Deployment

Before a broader release, developers can paste specific target IDs to deploy the hotfix to a strictly controlled micro-segment. This ensures the fix is validated safely with minimal blast radius.

Release Approval

Mandatory Security Gate

The system enforces a hard stop before the Canary phase. Subsequent rollout pipelines remain strictly locked until manual approval is granted, effectively preventing unverified, high-risk deployments.

Canary Observation & GA Rollout

Canary Release

Unlocks incremental rollout to a subset of real users. Equipped with real-time metric tracking and a one-click "Rollback" mechanism to instantly halt anomalies and minimize the blast radius.

GA Rollout

Upon validating Canary stability, the hotfix is seamlessly pushed to 100% of users. The system archives end-to-end lifecycle logs and performance data, completing the resolution loop.
