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 […]

Kubernetes as a platform vs. Kubernetes as an API

Introduction What is Kubernetes? I have been working on this technology since the beginning and after 8 years, I’m still having a problem defining what it is. Some people define Kubernetes as a container orchestrator but does that definition capture the essence of Kubernetes? I don’t think so. In this post, I’d like to explore […]

Optimizing your Kubernetes compute costs with Karpenter consolidation

Introduction Karpenter was built to solve issues pertaining to optimal node selection in Kubernetes. Karpenter’s what-you-need-when-you-need-it model simplifies the process of managing compute resources in Kubernetes by adding compute capacity to your cluster based on a pod’s requirements. With the recent release of workload consolidation, Karpenter can now be enabled to continuously monitor and optimize […]

EKS Persistent Volumes for Instance Store

The Kubernetes project is made up of a number of special interest groups (SIGs) that focus on a particular part of the Kubernetes ecosystem. The Storage SIG is focused on different types of storage (block and file) and ensuring that storage is available to containers when they are scheduled. One of the subprojects of the Storage […]

Transparent encryption of node to node traffic on Amazon EKS using WireGuard and Cilium

Introduction As the move to cloud native architectures continues to accelerate, one of the common challenges we hear from our customers is that adopting security best practices in Kubernetes clusters can be challenging. One area in particular that has come up in conversations often is how best to encrypt data in transit. This data encryption […]

Microservices development using AWS controllers for Kubernetes (ACK) and Amazon EKS blueprints

Introduction Microservices architectures make applications easier to scale and faster to develop, which enables innovation and accelerating time-to-market for new features. For business applications with multiple clients (web, mobile, desktop, and smart devices), the application programming interface (API) Gateway microservices design pattern is helpful for adding centralized control and security. Containers and serverless are two […]

Exposing Kubernetes Applications, Part 3: Ingress-Nginx Controller

Introduction The Exposing Kubernetes Applications series focuses on ways to expose applications running in a Kubernetes cluster for external access. In Part 1, we explored Service and Ingress resource types that define two ways to control the inbound traffic in a Kubernetes cluster. We discussed handling of these resource types via Service and Ingress controllers, […]

Exposing Kubernetes Applications, Part 2: AWS Load Balancer Controller

Introduction The Exposing Kubernetes Applications series focuses on ways to expose applications running in a Kubernetes cluster for external access. In Part 1 of the series, we explored Service and Ingress resource types that define two ways to control the inbound traffic in a Kubernetes cluster. We discussed the handling of these resource types via […]
