ARC zonal shift support for EKS Auto Mode and Karpenter
In this post, we walk through how zonal shift integrates with Amazon Elastic Kubernetes Service (Amazon EKS) and what happens when a shift is triggered. We also show how to enable it on both self-managed Karpenter and EKS Auto Mode (EKS Auto) clusters.
Running containerized hybrid nodes with Amazon Elastic Kubernetes Service
EKS hybrid nodes is a feature of Amazon Elastic Kubernetes Service (EKS) that allows you to use an EKS managed control plane with worker nodes that reside outside of the AWS cloud. In this blog post, we’ll explore how to run a Docker container that connects to an EKS cluster as a hybrid node.
Enhance Kubernetes high availability with Amazon Application Recovery Controller and Karpenter integration
In this post, we explain the benefits of using Amazon Application Recovery Controller (ARC) for improving application resiliency and why we built a built a Kubernetes controller to integrate Karpenter with ARC’s zonal shift.
Accelerate the testing and verification of Amazon EKS upgrades with upgrade insights
Introduction Amazon’s Elastic Kubernetes Service (Amazon EKS) removes a lot of the heavy lifting that goes into managing Kubernetes. For example, AWS manages the Kubernetes control plane on your behalf, including patching, tuning, and updating it as necessary. Then there are features such as managed node groups that give you a mechanism for managing the […]
Enhanced VPC flexibility: modify subnets and security groups in Amazon EKS
Introduction With Amazon Elastic Kubernetes Service (Amazon EKS) users can modify the configuration of the cluster before and after cluster creation without having to create a new cluster. Before provisioning the cluster, users can define specific parameters like the Kubernetes version, VPC and subnets, and logging preferences. Post-creation, they can dynamically adjust various settings, such […]
AWS Fargate adds support for larger ephemeral volumes
Introduction AWS Fargate is a serverless, pay-as-you-go compute engine that allows you focus on building applications without having to manage servers. Starting today, the amount of ephemeral storage you can allocate to the containers in a EKS Fargate pod is configurable up to a maximum of 175 GiB per pod. Prior to this launch, all […]
Scaling Kubernetes with Karpenter: Advanced Scheduling with Pod Affinity and Volume Topology Awareness
This post was co-written by Lukonde Mwila, Principal Technical Evangelist at SUSE, an AWS Container Hero, and a HashiCorp Ambassador. Introduction Cloud-native technologies are becoming increasingly ubiquitous, and Kubernetes is at the forefront of this movement. Today, Kubernetes is seeing widespread adoption across organizations in a variety of different industries. When implemented properly, Kubernetes can […]
Amazon EKS improves control plane scaling and update speed by up to 4x
Years before Amazon Elastic Kubernetes Service (EKS) was released, our customers told us they wanted a service that would simplify Kubernetes management. Many of them were running self-managed clusters on Amazon Elastic Computer Cloud (EC2) and were having challenges upgrading, scaling, and maintaining the Kubernetes control plane. When EKS launched in 2018, it aimed to […]
Using Dex & dex-k8s-authenticator to authenticate to Amazon EKS
This post was contributed by Márk Sági-Kazár, Jeremy Cowan, and Jimmy Ray. Introduction In an earlier post, Paavan Mistry introduced us to the OIDC identity provider (IdP) authentication for Amazon Elastic Kubernetes Service (Amazon EKS), a feature that allows you to use an OIDC identity provider with new or existing clusters. Before launching this feature, […]
Graceful shutdowns with ECS
February 2023: Parts of this blog are no longer accurate. Following enhancements to the ELB integration for ECS services, tasks running on Fargate Spot will be deregistered from a target group if it receives a spot termination notice before a SIGTERM is issued to the Task. Introduction Amazon Elastic Container Service (Amazon ECS) gives customers […]
