SnowOps Labs is a Kubernetes practice lab that builds a local cluster, injects realistic failures, and grades your fixes through guided scenarios and incidents.

| 2 |  Ben Poland, Senior Staff Platform Engineer @ Faire, discusses the unexpected Kubernetes scaling challenges his team encountered when migrating their CI system from Jenkins to Buildkite.
He explains how their new architecture created thousands of smaller pods instead of fewer large ones, which exposed internal Kubernetes throttling mechanisms they hadn't anticipated.
The team also hit etcd space limitations due to the sheer number of concurrent pods running in their managed Kubernetes clusters.

| 3 | This article explains three things that make DNS feel strange inside Kubernetes on AWS: the ndots setting, NodeLocal DNS caching, and a hidden per-ENI packet limit.

| 4 | EKS Hybrid Nodes addresses almost every on-prem Kubernetes pain point — without requiring a full cloud migration.
Raglin Anthony explains how: AWS manages the control plane (patching, scaling, hardening), while your worker nodes stay on-premises. EKS Pod Identity and IAM roles for service accounts handle identity natively. Networking reuses your existing VPN or Direct Connect setup. And nodeadm handles node upgrades.
You keep control of your infrastructure. AWS takes the control plane burden.

| 10 |  What does the next decade of Kubernetes look like?
Alex Kestner predicts the infrastructure powering Kubernetes clusters will become more and more invisible. Customers will focus on the applications that delight their users — not on managing the platform underneath.

| 11 | This case study shows why a Kubernetes liveness probe must not depend on downstream services after one caused payment pods to restart repeatedly, and how separate readiness and liveness checks avoid the same failure.

| 12 |  LearnKube Day includes ten five-minute lightning talks from Kubernetes practitioners sharing practical lessons with the community.
Brandt Keller, Staff Software Engineer at Defense Unicorns, is one of the featured lightning-talk speakers at LearnKube Day Salt Lake City 2026.
The event brings together a hands-on Kubernetes workshop, technical sessions, open Q&A, lightning talks, YAML Games, and a community reception.

| 13 | AI review works best when the context is simple. It falls apart when the system is not.
Artem Lajko draws a line between low-context tasks, like generating a small policy, and rich-context systems with cascading Helm charts and domain-specific assumptions. In those cases, the model may produce output that looks plausible but does not fit the real platform. | 305 |
| 14 |  KubeIntellect lets you troubleshoot Kubernetes in plain English by checking kubectl, Prometheus, and Loki, while requiring human approval before it changes the cluster.

| 15 | Dave Masselink, Software Engineer and Founder at Compute Gardener, breaks down how their scheduler achieved 50% carbon emission reductions for deferrable workloads.
He explains a crucial distinction: these savings come from temporal shifting rather than energy efficiency - the same jobs run using the same energy, but at times when the power grid has lower carbon intensity.
Dave describes how California's grid experiences 5-7x swings in carbon intensity throughout the day, creating opportunities for "carbon emission arbitrage."

| 19 |  Why can a Go service be OOM-killed while its heap looks healthy?
The heap is only part of the container's memory usage. Goroutine stacks, native allocations, and runtime overhead also count toward the container limit.
In this new article from Gulcan, you will learn:
- How CPU quotas affect Go's parallelism and why extra threads can increase throttling.
- How to measure total container memory, including goroutine stacks and native allocations.
- Why a tighter memory budget can increase garbage collection work and reduce throughput.
