From Zero To Hero with Red Hat Developer Hub

OpenShift Commons Gathering — Buenos Aires 2026

Welcome to the Workshop

In this workshop you will use Red Hat Developer Hub as a self-service development portal to build, deploy, secure, and observe applications on OpenShift — enhanced by AI assistance through Lightspeed and the MCP Gateway.

What You Will Learn

Use Software Templates to scaffold backend, frontend, and MCP services
Observe automated Tekton pipelines, ArgoCD GitOps, and Topology views
Secure APIs with Connectivity Link policies (OIDC and API Key via Kuadrant)
Interact with Developer Lightspeed for AI-assisted development
Use OpenShift Lightspeed with MCP Gateway for cluster operations
Monitor the platform with Grafana, Kiali, and distributed tracing

The Business Case: Neuralbank

Neuralbank is a financial institution modernizing its technology stack. As a developer, you will build three components through Developer Hub:

Component	Description
Customer Service MCP	MCP (Model Context Protocol) server — exposes backend operations as AI-callable tools
Neuralbank Backend	Quarkus REST API for customer management and credit scoring
Neuralbank Frontend	Web SPA connected to backend and MCP through the Kuadrant gateway
