Scheduler Framework demo

This repo is a demo for the feature scheduler framework based on kubernetes 1.16.

Note that the feature scheduler framework in kubernetes 1.15 is in alpha, and this feature will not graduate to Beta in 1.17/1.18.

For the progress of the scheduler framework, please refer to the enhancements.

Get Started

• Deploy

kubectl apply -f ./deploy/

• Build local

make local

• Build image

make image

How the dependencies inited for kubernetes 1.16.

pin all the dependencies to a matching level of k8s.io/kubernetes. You can use v0.x.y for the published components that correspond to Kubernetes v1.x.y without needing to figure out the timestamps/hashes. This is available in 1.15.10+, 1.16.4+, and 1.17.0+. For Kubernetes 1.16, all the dependencies lists as below.
