// KEP-4671 landed gang scheduling in Kubernetes 1.37 beta, behind a feature gate that is off by default. A four-node Kind cluster with six fake DRA GPUs shows the partial-placement deadlock, the single field that fixes it, and the two limits nobody documents: the Job field is pruned silently without a second alpha gate, and workload-aware preemption cannot reclaim DRA devices.

// Part two of the Modelplane fleet inference series, covering the layer above the scheduler. ModelService is a routing policy rather than a load balancer, spec.stack Dynamo swaps the whole gang-scheduling machinery, and four documented gotchas will cost you an afternoon each.
// A hands-on tour of Modelplane, the Crossplane-based control plane for AI inference across a fleet of GPU clusters. Two regions on Kind with fake DRA GPUs, the platform/developer contract written in DRA's own vocabulary, fleet-level drain, and the release trap that costs you two APIs.
// Choragos runs a team of AI coding agents with a real division of labour: an orchestrator that plans and delegates, workers with their own context, model and credentials, and a delegate/work-done protocol carrying work between them. A walkthrough of v0.11.2 with config recipes for real teams.
// How I built and shipped Pinax, an LLM-buildable dashboard framework for Obsidian, using Claude Code: the guardrails that made agentic development work, the automated review battles, and why machine-checkable success criteria beat vibe coding.
// Sphragis is a self-hosted Go gateway that strips PII out of every LLM request and response before it leaves your network and writes a tamper-evident, hash-chained audit log. A walkthrough of the v0.3.0 release: local redaction, reversible tokenization, multi-provider routing, and OpenTimestamps anchoring.
// How to use Dapr, Flux, Harbor, and a shared Helm chart to safely host apps built by non-technical citizen developers using LLMs on Kubernetes.
// MCP servers like DBHub expose databases, filesystems, and code execution over HTTP with zero authentication. Learn how to deploy OAuth2-Proxy on Kubernetes to add SSO, group-based access control, and session management to any MCP server without changing a single line of code.
// A guide to Knative for SREs and Platform Engineers. Learn how Knative Serving, Eventing, and Functions bring serverless capabilities to any Kubernetes cluster with autoscaling, scale-to-zero, and event-driven architectures.
// Learn how to automate Pod Disruption Budget management in Kubernetes using the PDB Management Operator. This guide explores the operator's architecture, dual configuration model, enforcement modes, and demonstrates how to use it for enterprise-grade availability management in ODA Canvas environments.
