Benchmarking Log Collectors, ListenerSet in Gateway API v1.5, eBPF GPU Monitoring, Modernizing Image Promoter, Zero-Downtime Disk Migration

This issue is brought to you by Dash0 — OpenTelemetry-native observability that takes minutes, not months. Full visibility into your logs, metrics, and traces with no lock-in and transparent pricing.

Articles

  1. Benchmarking Kubernetes log collectors: vlagent, Vector, Fluent Bit, OpenTelemetry collector, and more

    victoriametrics.com

    This article compares major Kubernetes log collectors with a reproducible benchmark focused on:

    • throughput,
    • CPU,
    • memory,
    • and log loss under production-like load.
  2. Understanding OpenTelemetry Support in kgateway

    www.dash0.com

    This article analyzes how kgateway handles OpenTelemetry observability across traces, logs, and metrics, covering signal quality, semantic conventions, and what works well versus where it falls short for platform teams.

  3. Exploring ListenerSet in Gateway API v1.5

    blog.howardjohn.info

    This article explains how ListenerSet in Gateway API v1.5 separates listeners from Gateways so teams can restore self-service TLS management across namespaces and scale beyond the old listener limit.

  4. X-Ray Vision for GPUs: eBPF Monitoring on Kubernetes

    mketkar.substack.com

    This article explains how to monitor GPU inference nodes on Kubernetes with eBPF and bpftrace by tracing NVIDIA driver calls, kernel behavior, and DaemonSet-based deployment patterns.

  5. The Invisible Rewrite: Modernizing the Kubernetes Image Promoter

    kubernetes.io

    This article explains how the Kubernetes Image Promoter was rewritten to improve rate limiting, observability, and resilience in the pipeline that publishes and signs images for registry·k8s·io.

  6. In-place PVC re-binding: zero-downtime disk migration on Kubernetes

    blog.cleancompute.net

    This case study explains how to migrate bound Kubernetes volumes from deprecated in-tree Azure Disk provisioning to CSI with in-place PVC re-binding, minimal restarts, and no data loss across production disks.

Articles worth checking out:

"Supports OpenTelemetry" means nothing anymore.

75% of organizations run or evaluate OTel, yet two projects can both claim support while delivering completely different results.

A proposed 7-dimension maturity model finally gives platform teams a shared language to tell them apart.

  2. From Docker Compose to Kubernetes on AWS: A Hands-On Migration Story

    medium.com

    This tutorial walks through moving a five-service Java app from Docker Compose to Kubernetes on AWS by rebuilding networking, secrets, ingress, persistence, and service discovery step by step.

  3. Connecting Multi-Cloud Applications with Cilium

    aws.plainenglish.io

    This tutorial explains how to connect applications across AWS and GCP Kubernetes clusters with Cilium Cluster Mesh, VPN networking, and VXLAN to enable east-west multi-cluster communication.

  4. Automated GitOps: from ECR push to EKS deploy

    medium.com

    This tutorial shows how to automate EKS deployments with Argo CD, Argo CD Image Updater, GitHub, and Amazon ECR so new container images flow to the cluster through GitOps without manual deployment steps.

  5. Build a Kubernetes Cluster at Home with Raspberry Pis

    dev.to

    This tutorial teaches how to build a home Kubernetes cluster with four Raspberry Pis, including network design, NAT, DHCP, Ubuntu setup, and worker node connectivity on a private subnet.

SaaS with Kubernetes Operators and Garbage Collection

A single Kubernetes CRD for every service request turns small changes into full-platform reconciliations.

Alexander Held, former platform engineer at Mercedes-Benz Tech Innovation, describes a production refactor from a 2,000-line CRD to purpose-built resources and controllers. He shows how teams can model business workflows as Kubernetes APIs and then use owner references, finalizers, and events to keep platform operations predictable.

You will learn:

  • Why monolithic CRDs create performance and troubleshooting problems
  • How controllers turn database provisioning and backups into reconciliation loops
  • How finalizers clean up external resources such as S3 backups
  • Why Kubernetes events make platform workflows easier to debug
