Stop Hunting Logs, 7000 Deployments with GitOps, Replacing the Default Scheduler, Micro Frontends, Vulnerabilities in Helm Charts
This issue is brought to you by vCluster and LearnKube — join "Multi-Tenancy March" starting Feb 24: a free 3-part hands-on series on namespace isolation, virtual clusters, GPU sharing, and AI agent sandboxing on Kubernetes.
Hi, Dan here!
This Thursday we’re running The YAML Games (Feb 19, 5pm CET / 8am PT) — a live cloud native quiz show, now online for the first time.
Quickfire rounds, team trivia, prizes, and at least one question that makes everyone groan. 30 minutes, zero config required.

Stop Hunting Logs: How OpenTelemetry Brings Metrics, Logs, and Traces Together
hackernoon.com
This article explains how OpenTelemetry unifies observability by correlating metrics, logs, and traces through standardized telemetry data collection in Kubernetes environments.
Continuous Frontend Deployments at Scale: 7000 Deployments/Month with GitOps
people.wayground.com
This case study shows how Wayground handles 7,000 frontend deployments per month across 50 engineers using GitOps and ArgoCD with zero deployment queues or approval processes.
How we replaced the default Kubernetes scheduler to optimize our continuous integration builds
codefresh.io
This case study shows how Codefresh optimized Kubernetes for CI workloads by creating a custom scheduler that packs pods tightly and uses ballast pods to eliminate build start delays.
Building Production-Ready Micro Frontends in Kubernetes: A Pragmatic Approach
medium.com
This tutorial teaches how to build and deploy production-ready micro frontends in Kubernetes.
It also covers configuring ingress routing for module federation, and implementing CI/CD pipelines for isolated micro frontend teams.
Detecting vulnerabilities in public Helm charts

This article shows how to scan Helm charts for insecure RBAC, secret leaks, and malicious templates using tools like Trivy, GitHub Search, and OPA.
Kubernetes Multitenancy March: A Free 3-Part Series
Not all multitenancy is created equal — a namespace won’t cut it when you need CRD isolation, and a dedicated cluster is overkill when you just need a sandbox.
This series walks through the actual trade-offs: what breaks, what scales, and what to pick for your specific setup.

GPU-accelerated headless Chromium on Kubernetes: a practical guide
medium.com
This guide explains how to configure GPU-accelerated headless Chromium on EKS, enabling hardware acceleration by mounting host GPU drivers, and resolving AWS EC2's virtual GPU conflicts, achieving a 2x speedup in video rendering tasks like Remotion.
Kubernetes nodes on EKS can take over a minute to become ready, and pods often wait even longer — but most teams never look into why.
Jan Ludvik, Senior Staff Reliability Engineer at Outreach, shares how he cut node startup from 65 to 45 seconds and reduced P90 pod startup by 30 seconds across ~1,000 nodes — by tackling overlooked defaults and EBS bottlenecks.
In this episode:
- Why Kubelet's serial image pull default quietly blocks pod startup, and how parallel pulls fix it
- How EBS lazy loading can silently negate image caching in AMIs — and the critical path workaround
- A Lambda-based automation that temporarily boosts EBS throughput during startup, then reverts to save cost
- The kubelet metrics and logs that expose pod and node startup latenc,y most teams never monitor
Every second saved translates to faster scaling, lower AWS bills, and better end-user experience.
