Migrating from Kubernetes Dashboard to Headlamp: a practical guide
A 2026 guide details how to replace Kubernetes Dashboard with Headlamp, shifting from form-based deployments to YAML-driven workflows and multi-cluster management.
Tuning Linux swap parameters for stable Kubernetes nodes
A deep dive into kernel parameters like swappiness and watermarks reveals how to safely enable swap in Kubernetes v1.34 without triggering OOM kills.
Handling GPU failures in Kubernetes for AI workloads
Kubernetes lacks native support for partial device failures, forcing engineers to build custom remediation logic for expensive AI and ML training jobs.
Kubernetes adds image compatibility metadata via Node Feature Discovery
A new specification allows container images to declare host OS and hardware requirements, enabling automated validation before scheduling in Kubernetes clusters.
Kubernetes introduces Gateway API extension for LLM inference routing
The Kubernetes project released the Gateway API Inference Extension to standardize routing for generative AI workloads, reducing latency and improving GPU utilization.
Kubernetes v1.33 fixes private image reuse across pods
Kubernetes v1.33 introduces a new verification mechanism to prevent unauthorized pods from reusing private container images already present on a node.
Kubernetes v1.33 introduces streaming list responses to cut API server memory use
Kubernetes v1.33 adds streaming encoding for List responses, reducing kube-apiserver memory usage by up to 20x during large dataset fetches and improving cluster stability.
Kubernetes v1.33 enables user namespaces by default for better isolation
Kubernetes v1.33 enables Linux user namespaces by default, allowing pods to run as root internally while remaining unprivileged on the host.
Kubernetes 1.32 introduces API streaming to fix list request memory spikes
Kubernetes 1.32 graduates watch lists to beta, allowing clients to stream large resource collections and prevent API server out-of-memory crashes.
Kubernetes v1.32 enables QueueingHint to optimize pod scheduling throughput
Kubernetes v1.32 re-enables the QueueingHint feature by default, allowing plugins to precisely determine when unschedulable pods should be retried, reducing wasted scheduler cycles.
Building dynamic Kubernetes APIs without custom controllers
Cozystack engineers explain how they used the Kubernetes API aggregation layer to create dynamic, imperative endpoints and bypass etcd storage limitations.
How Kubernetes CRI handles exec, attach, and port forwarding
A 2024 deep dive explains the unique URL-based streaming architecture behind Kubernetes Container Runtime Interface commands.
Building a private cloud on bare metal with Kubernetes and Talos Linux
A technical guide details how to construct a self-hosted cloud platform using Kubernetes, Talos Linux, and GitOps tools to manage bare metal infrastructure.
Kubernetes resource limits: balancing predictability and efficiency
A 2023 analysis argues that setting CPU and memory limits in Kubernetes improves performance predictability, even if it reduces raw cluster efficiency.
