Runtime frontend configuration (no rebuild)

This repo supports injecting frontend configuration at runtime (container start) instead of baking values into the Vite build.

Why

• You can deploy the same frontend image to different domains/environments by changing Kubernetes values/env vars.
• Domain migrations (e.g. domain1 → domain2) become much easier.

How it works

• The frontend loads /config.js before the React app starts.
• /config.js defines window.__RUNTIME_CONFIG__.
• The app reads config via getRuntimeConfig() (src/frontend/src/runtimeConfig.ts).
• In Kubernetes, the chart runs a frontend-assets initContainer that:
  • syncs built assets into a shared volume
  • writes /frontend_html/config.js from env vars

Notes

• If you use .env files in local dev, use Vite’s standard VITE_* prefixes:
