Repository for out-of-tree scheduler plugins based on the scheduler framework.
This repo provides scheduler plugins that are exercised in large companies. These plugins can be vendored as Golang SDK libraries or used out-of-box via the pre-built images or Helm charts. Additionally, this repo incorporates best practices and utilities to compose a high-quality scheduler plugin.
Container images are available in the official scheduler-plugins k8s container registry. There are two images one for the kube-scheduler and one for the controller. See the Compatibility Matrix section for the complete list of images.
docker pull k8s.gcr.io/scheduler-plugins/kube-scheduler:$TAG
docker pull k8s.gcr.io/scheduler-plugins/controller:$TAGYou can find how to install release image here.
The kube-scheduler binary includes the below list of plugins. They can be configured by creating one or more scheduler profiles.
- Capacity Scheduling
- Coscheduling
- Node Resources
- Node Resource Topology
- Preemption Toleration
- Trimaran
Additionally the kube-scheduler binary includes the below list of sample plugins. These plugins are not intended for use in production environments.
The below compatibility matrix shows the k8s client package (client-go, apimachinery, etc) versions that the scheduler-plugins are compiled with.
The minor version of the scheduler-plugins matches the minor version of the k8s client packages that
it is compiled with. For example scheduler-plugins v0.18.x releases are built with k8s v1.18.x
dependencies.
The scheduler-plugins patch versions come in two different varieties (single digit or three digits).
The single digit patch versions (e.g., v0.18.9) exactly align with the the k8s client package
versions that the scheduler plugins are built with. The three digit patch versions, which are built
on demand, (e.g., v0.18.800) are used to indicated that the k8s client package versions have not
changed since the previous release, and that only scheduler plugins code (features or bug fixes) was
changed.
