EKS News 009

This week we’ll talk about Bottlerocket NVIDIA GPU support, the Spinnaker Operator on Amazon EKS, Amazon EKS Anywhere and EKS on AWS Outposts, and some of the latest morsels of news from the greater cloud native ecosystem.

Bottlerocket adds support for GPU based EC2 instance types powered by NVIDIA

  • Bottlerocket, a Linux based container operating system, now supports NVIDIA GPU based EC2 instance types
  • Customers can reduce operational and cognitive overhead in managing container hosts with different operating systems bringing consistency of operating system experience
  • Customers can choose the new Bottlerocket AMI using EKS self-managed nodes and Karpenter on EC2 instances powered by NVIDIA.

Bottlerocket support for NVIDIA GPUs

  • Make an Amazon EKS cluster with NVIDIA GPU instances using Bottlerocket
  • The NVIDIA Bottlerocket variant supports both x86_64 and arm64 instance types
  • Integrated drivers provide seamless operating system updates and improves provisioning time

Managing Spinnaker using Spinnaker Operator in Amazon EKS

  • You can integrate Spinnaker for configuring Artifacts from Git, Amazon Simple Storage Service (Amazon S3), Amazon Elasti c Container Registry (Amazon ECR), and more
  • Spinnaker Operator lets you treat Spinnaker as just another Kubernetes deployment, which makes installing and managing Spinnaker easy and reliable
  • Build a Helm-based Spinnaker CD pipeline initiated by new Amazon ECR images deployed on Amazon EKS

Using Amazon EC2 Spot Instances with Karpenter

  • Karpenter is a dynamic, high performance cluster auto scaling solution for the Kubernetes platform
  • How to use Karpenter with EC2 Spot Instances and handle Spot Instance interruptions
  • Use EC2 Spot Instances with Karpenter to scale the compute needs in an Amazon EKS cluster

Building a multi-tenant Kubeflow environment on Amazon EKS using Amazon Cognito and ADFS

  • Kubeflow supports multi-tenancy, but only with local users and no namespace segregation
  • The blog describes how to integrate Kubeflow with Cognito and Microsoft ADFS as an identity provider and create the necessary preconditions for multi-tenancy and user/group segmentation
  • The code for this solution can be found in GitHub

Kubernetes at Scale without GitOps Is a Bad Idea

  • Kubernetes is well known for its declarative API
  • Templatizing defaults for Kubernetes objects and implementing them via GitOps allows for not only wider adoption but greater consistency
  • GitOps serves as the framework to take advantage of what Kubernetes was originally created to do

Flux for Helm Users

  • If you’re used to Helm, Scott Rigby, OpenGitOps co-chair, shows you how to make the leap to Flux
  • Easy path for bootstrapping Kubernetes nodes
  • Runs through rollbacks, which is one of those features you should appreciate and test
