Dokku Is Still Here After a Decade of Panel Waves: What the Original Single-Box PaaS Says About Coolify's 58K Stars and the Second-Machine Moment
Dokku has shipped since 2013 while Coolify passed 58,000 stars and Dokploy hit 35K — all solving the same first machine. Where single-box tools plateau, and how to graduate to a declarative fleet without a replatform.
DOKS Turned Every Node Into a Registry Mirror: What P2P Image Pulls Actually Save a Self-Hosted Fleet
DigitalOcean's Spegel-based P2P registry plugin hit GA in September 2026. Measured benchmarks, fleet-size math, and a self-host runbook show what peer-to-peer image pulls save in latency, egress, and rate-limit exposure.
E2B Runs 88% of the Fortune 100's Agent Workloads: What 150ms Firecracker Sandboxes Set as the Bar
E2B's Firecracker microVM sandboxes — 150ms boot, per-second billing, 88% Fortune 100 adoption — define what agent code execution must look like. A concrete five-component spec plus the self-hosted control-plane checklist.
Equinix Metal Is Dead: Where API-Driven Bare Metal Goes Next, and What the Shutdown Teaches About Provisioning Lock-In
Equinix Metal shut down June 30, 2026, ending the $335M Packet bet. A shutdown-timeline table, a five-door migration map with per-destination network and Cluster API stories, and why a provider API belongs behind an abstraction.
FerretDB v2 Speaks Mongo on Top of Your Existing CloudNativePG — If Postgres Carries the DocumentDB Extension
FerretDB v2 turns your existing CloudNativePG fleet into a MongoDB-compatible endpoint — but only if Postgres carries Microsoft's DocumentDB extension. The concrete CNPG recipe, what consolidation buys ops, and the verify-before-you-promise checklist.
Hetzner Pulled openSUSE 15 and Deprecated Debian 11: Rebuild Your CAPH Node Images Before November 30
Hetzner removed openSUSE 15 for new servers on July 30 and will do the same to Debian 11 after November 30. This runbook shows Cluster API (CAPH) operators how to audit pinned images, pick a replacement base, and roll the fleet before scale-up starts failing.
Hetzner's Post-July API Churn: The Primary IP Flip and Prometheus 3.14 Label Drop Your CAPH Fleet Still Hasn't Pinned
Hetzner's July datacenter removal was only the headline: unassigned Primary IPs flipped to assignee_type unassigned on August 1, Prometheus 3.14 dropped the Hetzner datacenter label, and the datacenters API goes 410 on October 1. A per-break fix table plus a six-grep audit runbook for CAPH fleets.
Hetzner After the June 2026 Price Hikes: Auction Metal vs Cloud VMs as Kubernetes Fleet Nodes
Hetzner's June 2026 hikes tripled dedicated cloud prices while auction boxes held at €37–€46 — a euro-level comparison of auction metal versus cloud VMs as Kubernetes fleet nodes, the operational tradeoffs, and which roles fit each.
Kubernetes 1.36 Locks On Fine-Grained Kubelet Authorization: The nodes/proxy Migration Your Multi-Tenant Fleet Owes Itself
Kubernetes 1.36 graduates fine-grained kubelet authorization to GA, replacing the over-broad nodes/proxy grant that lets read-only agents execute code in any pod. This playbook maps every kubelet endpoint to its least-privilege subresource and walks through the five-step migration for fleets running untrusted tenant workloads.
