DRA or HAMi? What Actually Shares Your GPUs in 2026

Kubernetes DRA now handles the scheduling half of GPU sharing, but runtime enforcement still belongs to HAMi. Here is the converged architecture, the concrete migration path, and which layer each fleet shape should standardize on.

Heroku Died but Its Buildpacks Run Everywhere: heroku/builder:26 on Cloud Run and the Builder Contract a Self-Hosted PaaS Owes

Heroku Died but Its Buildpacks Run Everywhere: heroku/builder:26 on Cloud Run and the Builder Contract a Self-Hosted PaaS Owes

Heroku's platform is in sustaining mode, but heroku/builder:26 builds OCI images that run on Cloud Run and anywhere else. The four-piece builder contract behind it, and the checklist a self-hosted PaaS must honor so ex-Heroku apps build unchanged.

Heroku's Fir Can't Deploy Your Dockerfile: a Migration Playbook With Real Before-and-After Bills

Heroku's Fir Can't Deploy Your Dockerfile: a Migration Playbook With Real Before-and-After Bills

Heroku's Fir generation can't deploy Docker images and Cedar entered sustaining mode in February 2026. A migration playbook for container teams: what breaks on Fir, how Render, Railway, and Fly.io handle Dockerfiles, and one typical stack priced five ways — $87 on Heroku, ~$35–60 hosted, ~$7 self-hosted.

Heroku Is in Sustaining Mode: When to Migrate and What Render, Railway, and Fly.io Really Cost

Heroku's February 2026 sustaining-mode announcement closed the door on new Enterprise contracts and froze new features. A timing framework for when to leave, a five-way cost table for the same workload on Heroku, Render, Railway, Fly.io, and Hetzner hardware, and where each alternative actually fits.

Ingress-NGINX Is Dead: Your Per-Route Migration Playbook Before the November 2026 Cliff

Ingress-nginx was archived in March 2026 and Azure ends managed NGINX patches in November 2026. A concrete migration plan: which annotations Traefik's drop-in provider covers, what must be hand-rewritten as HTTPRoute, and how to cut over one host at a time.

Instant Kubernetes Is 5-10 Minutes, Not Sub-Second: The Real Cost Math of Cluster-per-PR Preview Environments

Instant Kubernetes Is 5-10 Minutes, Not Sub-Second: The Real Cost Math of Cluster-per-PR Preview Environments

A Show HN promised instant Kubernetes with KVM and gRPC; its own numbers say 5-10 minutes per cluster. A scored comparison of five preview strategies and the fleet-scale math — node-hours, cold caches, control-plane sprawl — that decides cluster-per-PR vs namespace-per-PR.

Karmada for Cluster API Fleets: When One Control Plane Stops Being Enough

Karmada for Cluster API Fleets: When One Control Plane Stops Being Enough

Karmada's hub-and-member model promises cross-cluster scheduling, federated quotas, and taint-driven failover for Cluster API fleets — but it doubles your control planes. A verdict-first guide to what it buys, what it costs, and the quarterly ceiling test that says when.

TCPRoute Went Stable, but Somebody Still Has to Own the IP: kube-vip vs Talos BGP vs Hetzner LBaaS

TCPRoute Went Stable, but Somebody Still Has to Own the IP: kube-vip vs Talos BGP vs Hetzner LBaaS

Gateway API 1.6 made TCPRoute portable, but something still has to announce the IP. A worked comparison: kube-vip ARP is free but LAN-bound, Talos BGP is free but needs a peer, and Hetzner LBaaS costs ~€7.49 per TCP service — €37 at five services, €150 at twenty.

One Bad GPU Shouldn't Sink the Node: Kubernetes 1.37's DeviceTaintRule Goes Stable

One Bad GPU Shouldn't Sink the Node: Kubernetes 1.37's DeviceTaintRule Goes Stable

Kubernetes 1.37 promotes DRA device taints and tolerations to stable: a DeviceTaintRule fences one bad GPU with NoSchedule or NoExecute while the rest of the node keeps serving tenants. The YAML, the dry-run workflow, and what your health-check pipeline must build.
