# Scheduler extender

可以使用scheduler extender扩展scheduler，但要注意的是，目前是以http的方式进行扩展的，这会**影响scheduler的性能**，后面使用[新的scheduler framework](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/scheduling/scheduling-framework.md)后，以plugin方式改进后可能会好点。

Scheduler extender的编写规范见: [https://github.com/kubernetes/community/blob/master/contributors/design-proposals/scheduling/scheduler\_extender.md](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/scheduling/scheduler_extender.md)

编写extender时可参考样例：[https://github.com/everpeace/k8s-scheduler-extender-example。](https://github.com/everpeace/k8s-scheduler-extender-example%E3%80%82)
