    feat(supervisor): project-based scheduling affinity for image cache locality (#2995)

    frostbyte_neo 发布于 2026-02-04 13:39:47 +00:00 | 1177 次提交 在此版本后已推送到 main

    Adds optional pod affinity so pods from the same project prefer
    scheduling on the same node. This can help improve image cache hit
    rates; subsequent pods benefit from already-pulled image layers,
    reducing startup time.

    Complements the built-in ImageLocality scheduler plugin by helping
    during burst scheduling scenarios. Pod affinity sees scheduled pods
    immediately, while ImageLocality only sees images after they're fully
    pulled.

    Configuration:

    • KUBERNETES_PROJECT_AFFINITY_ENABLED - Enable/disable (default:
      false)
    • KUBERNETES_PROJECT_AFFINITY_WEIGHT - Scheduler weight 1-100
      (default: 50)
    • KUBERNETES_PROJECT_AFFINITY_TOPOLOGY_KEY - Topology key (default:
      kubernetes.io/hostname)

    Uses soft (preferred) affinity so pods always schedule even if preferred
    node is full.
