Changes to the Kubernetes Container Image Registry

Introduction The release of Kubernetes 1.25 was when it was first announced that the Kubernetes project would be updating its official container image registry endpoint from k8s.gcr.io to the community owned registry, registry.k8s.io. The goal was to eventually sunset the old registry over time. However, as highlighted on the official Kubernetes website, this changeover has […]

Deploying Amazon EKS Windows managed node groups

Introduction To help customers run their Windows applications in a more streamlined manner, we launched the support for Amazon EKS Managed Node Group (MNG) support for Windows containers on December 15, 2022. Amazon Elastic Kubernetes Service (Amazon EKS) MNGs automate the provisioning and lifecycle management of nodes (Amazon Elastic Compute Cloud [Amazon EC2] instances) for […]

Amazon EKS now supports Kubernetes version 1.25

Introduction The Amazon Elastic Kubernetes Service (Amazon EKS) team is pleased to announce support for Kubernetes version 1.25 for Amazon EKS and Amazon EKS Distro. Amazon EKS Anywhere (release 0.14.2) also supports Kubernetes 1.25. The theme for this version was chosen to recognize both the diverse components that the project comprises and the individuals who […]

How to rapidly scale your application with ALB on EKS (without losing traffic)

To meet user demand, dynamic HTTP-based applications require constant scaling of Kubernetes pods. For applications exposed through Kubernetes ingress objects, the AWS Application Load Balancer (ALB) distributes incoming traffic automatically across the newly scaled replicas. When Kubernetes applications scale down due to a decline in demand, certain situations will result in brief interruptions for end […]

Eliminate Kubernetes node scaling lag with pod priority and over-provisioning

Introduction In Kubernetes, the Data Plane consists of two layers of scaling: a pod layer and a worker node layer. The pods can be autoscaled using Horizontal Pod Autoscaler (HPA) or Vertical Pod Autoscaler. Nodes can be autoscaled using Cluster Autoscaler (CA) or Karpenter. If worker nodes are running at full capacity and new pods […]

Multi-cluster management for Kubernetes with Cluster API and Argo CD

Multi-cluster management for Kubernetes with Cluster API and Argo CD

Introduction Customers are moving to cloud thanks to its scalability and cost-effectiveness. Some are adopting Kubernetes to modernize their workloads for a more agile way to iterate and deliver time-to-market services or product features to their customers. As the number of clusters to be managed increases, customers struggle with different deployment mechanisms and application programming […]

Implementing Pod Security Standards in Amazon EKS

Implementing Pod Security Standards in Amazon EKS

Introduction Securely adopting Kubernetes includes preventing unwanted changes to clusters. Unwanted changes can disrupt cluster operations and even compromise cluster integrity. Introducing pods that lack correct security configurations is an example of an unwanted cluster change. To control pod security, Kubernetes provided Pod Security Policy (PSP) resources. PSPs specify a set of security settings that […]

Secure AWS Bottlerocket deployments on Amazon EKS with KubeArmor

Secure Bottlerocket deployments on Amazon EKS with KubeArmor

Introduction Bottlerocket is a security focused operating system (OS) image that provides out-of-the-box security options to protect host or worker nodes. While Bottlerocket is useful, the security of the pods and the containers is still the responsibility of the application developer or provider. KubeArmor, a CNCF (Cloud Native Computing Foundation) sandbox project, is a runtime […]
