Introduction In a Kubernetes cluster, the Horizontal Pod Autoscaler can automatically scale the number of Pods in a Deployment based on observed CPU utilization and memory usage. The autoscaler depends on the Kubernetes metrics server, which collects resource metrics from Kubelets and exposes them in Kubernetes API server through Metrics API. The metrics server has […]

Today, we are announcing Java support for cdk8s, the Cloud Development Kit for Kubernetes. This rounds out support for the top 3 most popular programming languages and probably the single most used here at Amazon. Now, you can leave YAML behind and define your Kubernetes applications in Typescript, Python, and Java. In this tutorial, we’ll […]

AWS Controllers for Kubernetes (ACK) is a new tool that lets you directly manage AWS services from Kubernetes. ACK makes it simple to build scalable and highly-available Kubernetes applications that utilize AWS services. Today, ACK is available as a developer preview on GitHub. In this post we will give you a brief introduction to the […]

Introduction A common approach to traffic routing in a Kubernetes cluster is to employ an Ingress Controller. The Ingress Controller is an application that runs in a cluster in conjunction with a load balancer and routes incoming HTTP/HTTPS/TCP requests to proxied servers according to routing rules specified in Ingress resources. When deploying to either a […]

Amazon Elastic Kubernetes Service (EKS) now supports EC2 Launch Templates and custom AMIs for managed node groups. When combined, these new features provide flexible configuration and customization options for Amazon EC2 instances which are managed as Kubernetes nodes by EKS. This enables you to leverage the simplicity of managed node provisioning and lifecycle management features […]

Previous AWS Container Day events have included a number of discussions and deep dives on running Kubernetes at AWS – and now we are bringing this content right to your home! Join us for the first-ever virtual Container Day on August 17th, 8:00 AM – 4:00 PM (PDT). Check out the agenda and some of […]

Many AWS customers use Amazon Elastic Kubernetes Service (Amazon EKS) to operate multi-tenant Kubernetes clusters where workloads that belong to different teams or projects run in a shared cluster. Customers like that Kubernetes offers centralized management of workloads, enabling administrators to create, update, scale, and secure workloads using a single API. In this post we […]

AWS recently launched a new service, EC2 Image Builder, which automates and simplifies the creation, maintenance, and validation of Amazon Machine Images (AMIs). Many of our customers are using this service to generate their own customized, hardened images. In this post, we will demonstrate how you can automatically test your Amazon Elastic Kubernetes Service (Amazon […]

At AWS, we’ve been exploring new approaches of making it easier to define Kubernetes applications. Last month, we announced the alpha release of cdk8s, an open-source project that enables you to use general purpose programming languages to synthesize manifests. Today, I would like to tell you about cdk8s+ (cdk8s-plus), which we believe is the natural […]

Update 12/05/20: EKS on Fargate now supports capturing applications logs natively. Please see this blog post for details. Amazon Elastic Kubernetes Service (Amazon EKS) now allows you to run your applications on AWS Fargate. You can run Kubernetes pods without having to provision and manage EC2 instances. Because Fargate runs every pod in VM-isolated environment, […]
