AI Chat OIDC + Ollama Cloud

This repository includes:

• backend/ — FastAPI service validating OIDC JWTs and proxying chat to Ollama Cloud with SSE streaming
• frontend/ — React + Vite + TypeScript UI performing OIDC Authorization Code Flow with PKCE
• docker-compose.yml — brings up backend, frontend, and optional Keycloak (dev-only)

Prerequisites

• Docker >= 24.0
• Docker Compose >= 2.0
• An Ollama Cloud API key
• An OIDC issuer URL, client ID, and client secret

Setup

1. Copy .env.example to .env and set values.
2. In the frontend, set VITE_OIDC_REDIRECT_URI to http://localhost:5173 or your UI URL.
3. If using the local Keycloak dev service, enable the dev profile:

docker compose --profile dev up --build

4. If you only want backend/frontend with an external OIDC provider:

docker compose up --build

API

• GET /health — health check
• GET /auth/config — OIDC discovery endpoints for the frontend
• POST /auth/callback — exchanges OIDC code for tokens
• POST /chat — protected chat endpoint streaming SSE from Ollama Cloud

Notes

• The backend requires OLLAMA_API_KEY in environment.
• The frontend stores the access token in localStorage for simplicity.
• OpenAPI docs are available at http://localhost:8000/docs.
