Hetzner Placement Groups and Cluster API: What Guarantees Your Control-Plane Anti-Affinity, and Why Autoscaled Workers Still Don't Get It
Hetzner's Placement Groups guarantee up to 10 VMs land on 10 different physical hosts — a free API primitive live since 2021. CAPH already wires it into control-plane provisioning. The Kubernetes cluster-autoscaler's Hetzner provider still can't, three years into an open feature request.
Highlight.io's Shutdown Is a Governance Checklist Your Observability Stack Needs
Highlight.io shut down as a standalone open-source tool on February 28, 2026 after LaunchDarkly acquired it. A five-question governance checklist backtested against Highlight itself, then scored against GlitchTip and SigNoz.
IPVS Is Deprecated in Kubernetes 1.35: What Actually Changes When kube-proxy Moves to nftables
Kubernetes 1.35 deprecates IPVS proxy mode in favor of nftables. Here's the concrete before/after — the load-balancing algorithm you lose, the conntrack behavior shift, and a node-by-node rollout sequence — for migrating a self-hosted fleet's kube-proxy before the next cluster upgrade.
Dynamic Resource Allocation Comes of Age in Kubernetes 1.36: Scheduling GPUs Declaratively Instead of Renting a Managed Tier
Kubernetes 1.36 matures Dynamic Resource Allocation's GPU-scheduling features right as Fly.io kills its GPU line — here's what DeviceClass and ResourceClaim actually replace, and the real cost math between owning a Hetzner GPU and renting one by the second.
Kubernetes Just Deprecated externalIPs. Here's the Exact Migration Path for Bare Metal
Kubernetes 1.36 deprecated Service externalIPs over a security hole the project never patched. Here's the exact four-stage removal timeline and the commands to migrate a bare-metal fleet to MetalLB before the default flips in 1.40.
Kubernetes 1.36 Ships Gang Scheduling In-Tree: What It Actually Buys an AI-Agent Batch Fan-Out
Kubernetes 1.36 ships PodGroup and Workload APIs in-tree, letting the scheduler gang-schedule a multi-pod fan-out atomically. Here's exactly what the five alpha feature gates do, what they replace Volcano/Kueue for, and how far alpha still is from safe for tenant workloads.
Your Kubernetes Install Doesn't Have a Finish Line — And More Docs Won't Give It One
Why self-hosted Kubernetes installs for AI platforms stall for weeks, and why owning the node fleet with Cluster API fixes what better documentation can't.
Kubernetes 1.35 Killed the CPU Restart Tax. Memory Still Pays It.
Kubernetes 1.35 made CPU resizes truly restart-free, but memory resizes still restart the container by default. Here's the resizePolicy mechanics, the real constraints, and how a self-hosted PaaS should wire this into its tenant plan-upgrade flow.
Lagoon Outlived Its Mirantis Acquisition: What a Drupal-Born Kubernetes PaaS Still Gets Right
Lagoon, the Drupal-born Kubernetes PaaS Mirantis acquired in 2022, still automates per-branch config-imports and database provisioning that Coolify, Dokploy, Kubero, and Canine haven't fully matched — a concrete look at the mechanism and what a general-purpose platform has to build to catch up.
