Production deployment now matches the host setup that already runs neuronetz.ai / neuro-landing: the gateway sits behind the jwilder nginx-proxy + acme-companion already on the host, instead of bundling its own Caddy sidecar. - docker-compose.yml: drop the Caddy service entirely. The gateway joins an external `proxy` Docker network (the same one neuronetz-web / neuronetz-www use) and advertises itself with VIRTUAL_HOST / VIRTUAL_PORT / LETSENCRYPT_HOST / LETSENCRYPT_EMAIL. nginx-proxy routes TLS-terminated traffic to it on the shared network; acme-companion handles Let's Encrypt issuance + renewal for api.neuronetz.ai automatically. NO host ports are published in this compose file anywhere — gateway, postgres, redis, ollama all stay unreachable from the host. Pinned container_names (neuronetz-gateway / -postgres / -redis / -ollama) for stable identification by nginx-proxy and ops scripts. - .env.example: add GATEWAY_VIRTUAL_HOST + LETSENCRYPT_EMAIL; flip the default GATEWAY_TRUSTED_PROXIES to `127.0.0.1,nginx-proxy`. - docs/DEPLOYMENT.md: the canonical path is now jwilder-proxy. Reorganized prerequisites + steps around it; documented adding HSTS and the other security headers via the nginx-proxy custom-config mechanism (/etc/nginx/vhost.d/<host>). The Caddy sidecar lives on as a documented alternative for hosts without jwilder-proxy (ops/caddy/Caddyfile.example is kept). The Ollama-never-exposed non-negotiable is unchanged.
neuronetz-gateway
A secure, multi-tenant API gateway in front of an Ollama instance. It is the hot path of the Neuronetz API: every request to the models flows through here, authenticated, rate-limited, budgeted, and audited.
The Ollama backend is never reachable from the public internet. It is bound to an internal Docker network with no published ports. All access is via this gateway, behind TLS terminated by Caddy.
Status: v0.1.0 — in development. See
scope-docs/SPEC.mdfor the full specification andscope-docs/AGENT_PROMPT.mdfor the phased build plan.SPEC.mdis the source of truth.
What it does
- Auth — API keys as Bearer tokens, stored as Argon2id hashes, verified in constant time.
- Multi-tenant — tenants own keys; limits and budgets inherit tenant → key.
- Rate limiting — per-key and per-tenant RPM / TPM / concurrent connections.
- Budgets — daily / monthly / total token budgets, enforced fail-closed.
- Dual API surface — native Ollama (
/api/*) and OpenAI-compatible (/v1/*), both streaming. - Hard-blocked mutations —
/api/pull,/api/push,/api/create,/api/copy,/api/delete,/api/blobs/*always return 403. Not configurable. - Audit log — always-on request metadata; opt-in, TTL'd prompt logging per key.
Administration (dashboards, tenant self-service) lives in a separate service,
neuronetz-console; it is not part of this repository.
Architecture
Internet ──TLS──> Caddy ──HTTP──> gateway ──┬──> Postgres (keys, budgets, audit)
├──> Redis (key cache, rate limits)
└──> Ollama (internal network only)
Quickstart (dev)
Requires Docker + Docker Compose. The dev stack runs Postgres, Redis, and the gateway —
no Caddy and no Ollama (so /readyz reports 503 until a real Ollama backend is wired
in; that is expected).
git clone <repo> neuronetz-gateway && cd neuronetz-gateway
cp .env.example .env # adjust if you like; defaults work for local dev
docker compose -f docker-compose.dev.yml up --build
The gateway runs alembic upgrade head on startup, then serves on http://localhost:8080.
curl -i http://localhost:8080/healthz # -> 200 {"status":"ok"}
curl -i http://localhost:8080/readyz # -> 503 (no Ollama backend in the dev stack)
Production
docker-compose.yml brings up the full stack — Caddy (TLS via Let's Encrypt for
api.neuronetz.ai), the gateway, Postgres, Redis, and Ollama. The ollama service has
no ports: mapping and is reachable only on the internal Docker network. See
docs/DEPLOYMENT.md (added in a later phase) and
ops/caddy/Caddyfile.example.
Managing tenants and keys
Use the bootstrap CLI (Typer). Keys have the form nz_<prefix><secret>; the full key is
printed exactly once at creation and only its Argon2id hash is stored.
neuronetz-gateway create-tenant --name acme
neuronetz-gateway create-key --tenant acme --name prod-server-1
neuronetz-gateway list-keys --tenant acme
neuronetz-gateway revoke-key --prefix nz_abc12345
