Dokploy Killed Its Global Build Queue After Two Years: What Per-Server Build Slots Reveal About Scheduling Outgrowing One Box
Dokploy ran every build on every server through one global queue for two years — then v0.29.11 gave each server its own. The wait-time math behind the fix, where per-box caps still strand capacity, and what a fleet build pool owes default-1.
E2B Is Now Native in OpenAI's Agents SDK: The Bar a Self-Hosted Agent Sandbox Has to Clear
OpenAI's Agents SDK declares E2B sandboxes natively since April 2026. This post turns that integration into a six-part checklist — cold start, isolation, templates, lifecycle, MCP sandboxing, egress policy — and scores four self-hosted paths against it.
From Metered API to RuntimeClass: Building E2B-Style Sandboxes on Your Own K8s Fleet
The sandbox cost math already settled: past ~400 sandbox-hours a month, owned hardware wins. This is the build guide for what comes next — three paths to E2B-style sandboxes on your own fleet, with Kata Containers on Cluster API as the one that skips the second orchestrator.
Gateway API v1.5 Moves Six Features to Stable: Which Ones Your Git-Push PaaS Should Adopt First
Gateway API v1.5 graduates ListenerSet, TLSRoute, and four more features to the stable channel. A verdict table and migration checklist for platforms weighing the typed routing API against Ingress annotations.
kops Is Tracking Kubernetes 1.37 in 2026 — and Still Proves Why Cluster API Won the Heterogeneous Fleet
kops shipped 1.36 and already tracks Kubernetes 1.37 — yet its own release notes show why declarative Cluster API won fleets spanning clouds and bare metal, and which upgrade disciplines a self-hosted platform should steal from it.
KubeCon Japan 2026 Sold Out Again: What It Signals for a Hetzner-Only Fleet's APAC Roadmap
KubeCon Japan 2026 sold out for the second straight year. What the six-track lineup and Japan's enterprise demand data say about APAC appetite for Kubernetes — and the latency math a Hetzner-only fleet must face before expanding east of Singapore.
Deploy Agents That Wait: Building a Stateless Rollout-and-Approval Agent on MCP Tasks and Multi Round-Trip Requests
MCP's July 2026 release made the protocol stateless and gave agent builders Tasks and Multi Round-Trip Requests. Here is the concrete design for a deploy agent that returns a task handle, polls rollout status against Kubernetes Deployment conditions, and stops for an expiring human approval before promoting to production.
Preview Environments Are a Cost Problem Before They're a Feature: The 50-PR Math on Auto-Sleep and Auto-Destroy
At 50 concurrent PRs, always-on preview environments burn about $2,850 a month. Auto-sleep cuts the compute line, scale-to-zero database branches cut the data tier, and auto-destroy kills the 30% orphan drag — taking the bill to roughly $650. The line-by-line math, plus the three defaults a self-hosted platform should enforce.
Whole GPU or Nothing Is Over: Wiring DRA GPU Scheduling on a Bare-Metal Cluster API Fleet
Kubernetes' device-plugin era of whole-GPU-or-nothing scheduling is ending. What WG Device Management standardized with DRA, what coarse allocation costs a small bare-metal fleet, and the exact checklist a Cluster API fleet needs before tenants can deploy with a GPU.
