Neuron K8 Release Notes#

Introduction#

This document lists the current release notes for AWS Neuron Kubernetes (k8) components. Neuron K8 components include a device plugin and a scheduler extension to assist with deployment and management of inf/trn nodes within Kubernetes clusters. Both components are offered as pre-built containers in Public ECR and ready for deployment.

  • Device Plugin: public.ecr.aws/neuron/neuron-device-plugin:2.x.y.z

  • Neuron Scheduler: public.ecr.aws/neuron/neuron-scheduler:2.x.y.z

It’s recommended to pin the version of the components used and to never use the “latest” tag. To get the list of image tags (2.x.y.z), please refer to these notes or check the image tags on the repo directly.

To Pull the Images from ECR:

docker pull  public.ecr.aws/neuron/neuron-device-plugin:2.x.y.z
docker pull  public.ecr.aws/neuron/neuron-scheduler:2.x.y.z

Neuron K8 release [2.19.16.0]#

Date: 01/18/2024

Critical Security Patch#

We updated the dependencies used by the Neuron Device Plugin and the Neuron Kubernetes Scheduler to fix several important security vulnerabilities. This update fixes all security vulnerabilities reported in https://github.com/aws-neuron/aws-neuron-sdk/issues/817. Please see the ticket for all impacted dependencies and their associated vulnerabilities.

Neuron K8 release [2.16.18.0]#

Date: 09/01/2023

Major New Features#

  • Previously, the Neuron Device indexing was assigned randomly, which made programming difficult. Changed to using 0-based indexing for Neuron Devices and NeuronCores in EKS container environments; requires Neuron Driver version 2.12.14 or newer.

  • Improved logging when Neuron Driver not installed/present.

Bug Fixes#

  • Fixed Neuron Device Plugin crash when Neuron Driver is not installed/present on the host.

  • Fixed issue where pods fail to deploy when multiple containers are requesting Neuron resources.

  • Fixed issue where launching many pods each requesting Neuron cores fails to deploy.

Major New Features#

  • New scheduler extension is provided to ensure that kubelet is scheduling pods on inf1 with contiguous device ids. Additional details about the new scheduler are provided neuron-k8-scheduler-ext. including instructions on how to apply it.

    • NOTE: The scheduler is only required when using inf1.6xlarge and/or inf1.24xlarge

  • With this release the device plugin now requires RBAC permission changes to get/patch NODE/POD objects. Please apply the k8s-neuron-device-plugin-rbac.yml before using the new device plugin.
