AWS Builder Center turned one year old last week. Launched on July 9, 2025, the platform has grown from a community hub with Wishlist voting, community profiles, and a toolbox into a full ecosystem with sandbox environments, workshops, Spaces, and a Builders’ Library. To mark the anniversary, Rick Suttles published a full feature timeline covering […]

The Kubernetes project relies on transparency to empower cluster administrators and security researchers. One important way we do that is by publishing CVE records into the Common Vulnerabilities and Exposures database. As part of our ongoing effort to mature the official Kubernetes CVE Feed, we have identified some discrepancies. CVE records for a few older, unfixed issues incorrectly include a fixed version field. The Kubernetes Security Response Committee (SRC) will correct the affected CVE records on June 1, 2026. This may result in vulnerability scanners identifying these vulnerabilities in places where they were previously not detected…

SIG-Etcd announces the availability of the first beta release of etcd v3.7.0. This new version of the popular distributed database and key Kubernetes component includes the long-requested RangeStream feature, as well as a refactoring and cleanup of multiple legacy components and interfaces. v3.7 will deliver improved security, better operational reliability, and an improved experience for working with large resultsets. First, however, the project needs users to test the beta. You can find v3.7.0-beta.0 here: Source code Binaries Official container images Please try it out and report issues in the etcd repo. This beta also determines the EOL …

Back in Kubernetes 1.28, we introduced the Mixed Version Proxy (MVP) as an Alpha feature (under the feature gate UnknownVersionInteroperabilityProxy) in a previous blog post. The goal was simple but critical: make cluster upgrades safer by ensuring that requests for resources not yet known to an older API server are correctly routed to a newer peer API server, instead of returning an incorrect 404 Not Found. We are excited to announce that the Mixed Version Proxy is moving to Beta in Kubernetes 1.36 and will be enabled by default! The feature has evolved significantly since its initial release, addressing key gaps and modernizing its archite…

The .spec.externalIPs field for Service was an early attempt to provide cloud-load-balancer-like functionality for non-cloud clusters. Unfortunately, the API assumes that every user in the cluster is fully trusted, and in any situation where that is not the case, it enables various security exploits, as described in CVE-2020-8554. Since Kubernetes 1.21, the Kubernetes project has recommended that all users disable .spec.externalIPs. To make that easier, Kubernetes also added an admission controller (DenyServiceExternalIPs) that can be enabled to do this. At the time, SIG Network felt that blocking the functionality by default was too large a…

Dynamic Resource Allocation (DRA) has fundamentally changed how platform administrators handle hardware accelerators and specialized resources in Kubernetes. In the v1.36 release, DRA continues to mature, bringing a wave of feature graduations, critical usability improvements, and new capabilities that extend the flexibility of DRA to native resources like memory and CPU, and support for ResourceClaims in PodGroups. Driver availability continues to expand. Beyond specialized compute accelerators, the ecosystem includes support for networking and other hardware types, reflecting a move toward a more robust, hardware-agnostic infrastructure. W…

If you've ever tried to enforce a security policy across a fleet of Kubernetes clusters, you've probably run into a frustrating chicken-and-egg problem. Your admission policies are API objects, which means they don't exist until someone creates them, and they can be deleted by anyone with the right permissions. There's always a window during cluster bootstrap where your policies aren't active yet, and there's no way to prevent a privileged user from removing them. Kubernetes v1.36 introduces an alpha feature that addresses this: manifest-based admission control. It lets you define admission webhooks and CEL-based policies as files on disk, l…

Kubernetes v1.36 introduces Pod-Level Resource Managers as an alpha feature, bringing a more flexible and powerful resource management model to performance-sensitive workloads. This enhancement extends the kubelet's Topology, CPU, and Memory Managers to support pod-level resource specifications (.spec.resources), evolving them from a strictly per-container allocation model to a pod-centric one. Why do we need pod-level resource managers?When running performance-critical workloads such as machine learning (ML) training, high-frequency trading applications, or low-latency databases, you often need exclusive, NUMA-aligned resources for your pri…

After several years of development, User Namespaces support in Kubernetes reached General Availability (GA) with the v1.36 release. This is a Linux-only feature. For those of us working on low level container runtimes and rootless technologies, this has been a long awaited milestone. We finally reached the point where "rootless" security isolation can be used for Kubernetes workloads. This feature also enables a critical pattern: running workloads with privileges and still being confined in the user namespace. When hostUsers: false is set, capabilities like CAP_NET_ADMIN become namespaced, meaning they grant administrative power over contain…

Amazon Elastic Container Service (Amazon ECS) now supports built-in blue/green, linear, and canary deployment strategies for ECS services using Amazon VPC Lattice. Applications that use VPC Lattice for service-to-service communication across VPCs and AWS accounts can now take advantage of managed traffic shifting natively from Amazon ECS when rolling out updates. With this launch, ECS customers using VPC Lattice can shift traffic in a controlled manner during deployments, choosing how quickly traffic moves based on their confidence in each release: all at once with blue/green, in equal increments with linear, or starting with a small percent…

Kubernetes version 1.37 introduced several new features and bug fixes, and AWS is excited to announce that you can now use Amazon Elastic Kubernetes Service (EKS) and Amazon EKS Distro to run Kubernetes version 1.37. Starting today, you can create new EKS clusters using version 1.37 and upgrade existing clusters to version 1.37 using the EKS console, the eksctl command line interface, or through an infrastructure-as-code tool. Kubernetes version 1.37 introduces several key improvements, promoting the Metrics API to general availability as metrics.k8s.io/v1. This API provides Pod and node CPU and memory usage for the Horizontal Pod Autoscaler…

Amazon Bedrock AgentCore Gateway now supports TLS certificates signed by private certificate authorities (CAs) on MCP, OpenAPI, and HTTP proxy targets. This feature enables you to connect securely to gateway targets that use TLS certificates issued by your own private certificate authority. With this feature, you can establish native connections to private endpoints in your VPC without requiring an intermediate Application Load Balancer. You can register a private CA certificate with gateway targets that use private endpoints powered by Amazon VPC Lattice. The gateway fetches your PEM-encoded CA certificate from Amazon S3 or AWS Secrets Mana…
