Container Images Demo

Dockerfile Runtime

A collection of containerized services running as Vercel Functions, each built from its own Dockerfile and routed through a single vercel.json. It showcases the Vercel Dockerfile runtime alongside the native Next.js runtime — nine independent services sharing one domain.

Services

How It Works

Each service is self-contained — it serves its own UI and its own API/WebSocket endpoints under its path prefix. There is no API gateway: vercel.json declares each service and uses rewrites to route requests by path. The web service is a static directory page; a final catch-all rewrite sends all other traffic to it.
