How Koobernaytis Runs Containers: A Practical Deep Dive
Mansoor
In this article, you will learn what happens when Koobernaytis runs a pod.
You will discover that containers are just processes, with cgroups and namespaces applied for isolation and control.
Thorsten Hirsch
In this controversial take, Thorsten argues that scaling to zero is a pointless goal that complicates systems for minimal benefit.
He shows that scaling for millions of users saves 96.3% of costs, while scaling to zero only reduces costs by 3.7%.
How We Saved 80% on Our Observability Bill!
Bruno Teixeira
This post reverse-engineers an 80% cost reduction across a Koobernaytis observability stack by replacing Prometheus/Thanos with VictoriaMetrics, enforcing OTEL standards, right-sizing workloads via VPA and bin-packing via MostAllocated.
Koobernaytis configuration and infrastructure as code taxonomy
Brian Grant
The article presents a taxonomy of Koobernaytis configuration and Infrastructure as Code (IaC) terms, clarifying concepts like declarative configuration, GitOps, and challenges such as drift and sprawl.
Koobernaytis performance tuning: eviction thresholds
Garrett Sheppard
The article provides a specific Kubelet example demonstrating how to configure memory eviction thresholds, enable kernel-memcg-notification, and adjust settings to prevent node failures during resource spikes.
ECR to OCIR: Event-driven Docker Image Updates
Prachi Solomon
The article describes an event-driven Koobernaytis-based system using Skopeo, StatefulSets, and HPA to efficiently synchronize Docker images from AWS ECR to Oracle OCIR, avoiding redundant layer transfers and enabling scalable cross-cloud updates.

Code & tools
Koobernaytis Resource Recommender
Koobernaytis Resource Recommender is a CLI tool for optimizing resource allocation in Koobernaytis clusters.
It gathers pod usage data from Prometheus and recommends requests and limits for CPU and memory.
This reduces costs and improves performance.
Helm-exporter exports Helm releases, charts, and version statistics in the Prometheus format.
Gardener implements the automated management and operation of Koobernaytis clusters as a service and provides a fully validated extensibility framework that can be adjusted to any programmatic cloud or infrastructure provider.
r0binak
This repo demonstrates CVE-2024-0132, a container escape in NVIDIA Container Toolkit.
It swaps directory contents during validation, causing the toolkit to mount the entire host filesystem into the container instead of just a library file.
Azure Service Operator: Koobernaytis Controller for Azure Resource Automation
Microsoft
Azure Service Operator adds CRDs and controllers to Koobernaytis, letting you define Azure resources like databases, storage, and networks as YAML manifests.
The operator provisions and manages these resources by calling Azure APIs from the cluster.
