Containers

Amazon EKS 1.34 makes the Kubelet Checkpoint API functional, so you can capture a running container’s full state (memory, processes, and network connections) without stopping the workload. This post shows how to deploy an unprivileged checkpoint agent that stores forensic checkpoints in Amazon ECR as OCI images for later analysis.

With Amazon EKS, you can now configure Kubernetes control plane components (the API server, scheduler, and controller manager) directly through EKS APIs. This post explains what’s configurable and includes two hands-on walkthroughs: enabling MostAllocated bin-packing to optimize pod placement, and tuning event retention duration.

Running an OpenTelemetry collector as a sidecar in every Amazon ECS task does not scale across a multi-account estate, and it cannot run at all on Windows. Learn how to replace per-task sidecars with a single centralized ADOT gateway that ingests OTLP from workloads across accounts and exports traces to AWS X-Ray and metrics and logs to Amazon CloudWatch.

On Amazon EKS Auto Mode, node failures are detected, drained, and replaced automatically before anyone reaches for a laptop. This post shows how the Node Monitoring Agent and Karpenter form a detect-and-replace cycle that runs by default, why specific faults trigger node replacement, and how to collect node diagnostics without SSH.

Amazon ECS Express Mode gives you load balancing, scaling, logging, and networking out of the box. Learn how to extend an Express Mode service beyond its defaults with three hands-on examples: turning on ECS Exec, adding a scheduled scaling policy, and adding a FireLens log router as a sidecar container.

Deploy a single CloudFormation stack that builds a GPU batch inference pipeline on Amazon ECS Managed Instances. It uses Amazon SQS for job buffering and Application Auto Scaling to scale to zero when idle, so you pay only for active inference time.

In this post, we explain how zone-aware routing works and walk you through setting up a multi-AZ ECS cluster to see it in action.

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.

In this post, we explain how the JVM interacts with the container runtime and the host kernel, and walk through configuration best practices that help you prevent these issues.

In this post, we walk you through three main steps: First, you create an AWS CodeConnections host in your VPC with connectivity to your private Git server. Second, you establish a connection that Argo CD can use. Finally, you deploy a sample application to verify the integration. By the end, you have a secure way to deploy applications from private repositories.
