Round-2 changes locking in scaffold-phase decisions and adding ML/notebook stacks.
Locked decisions
- sql: postgres 16-alpine (was TBD); init.d/ mount for per-app DB provisioning
- nginx-proxy: stock nginx + certbot sidecar (was nginx:alpine TODO).
Chose stock over nginxproxy/nginx-proxy because stream{} is required for
MQTT-TLS reverse-proxy on tcp/8883 to rabbitmq:1883.
- gitea: HTTPS-only (DISABLE_SSH=true). No SSH port published.
MQTT split
- Remove stacks/mqtt placeholder.
- Add stacks/rabbitmq — general-purpose broker (AMQP + MQTT plugin),
used at both cloud and edge. External MQTT clients reach cloud broker
via nginx stream-proxy on 8883.
- Add stacks/mosquitto — reserved for the FROST (SensorThings) stack
only. Cloud-only. Internal to its own stack; no external ingress.
ML / notebooks (cloud-only)
- stacks/mlflow — experiment tracking + model registry. Postgres backend
on sql stack; local volume for artifacts (S3/MinIO is a TODO).
- stacks/jupyterhub — multi-user notebook server. DockerSpawner via
mounted docker.sock; users spawn into cloud-app network so they can
reach mlflow, influxdb (via grafana), rabbitmq.
Sites
- sites/gemaal1 — first edge deployment scaffold. Site-local override
template for binding nginx to PLANT_LAN_IP.
Docs
- README + docs/architecture.md updated: stacks table now lists 15 stacks,
ingress + attachment tables reflect mlflow/jupyterhub, TLS strategy
section locked, MQTT-split section added, Gitea HTTPS-only noted.

R&D infrastructure stacks for Waterschap Brabantse Delta. Hub-and-spoke deployment: one **cloud** central hub + per-plant **edge** sites.
|
|
|
|
## Layout
|
|
|
|
```
|
|
infra/
|
|
├── stacks/ # reusable, runnable stack defs (kebab-case)
|
|
├── cloud/ # the single central hub
|
|
├── sites/ # per-plant edge deployments
|
|
└── docs/ # architecture + conventions
|
|
```
|
|
|
|
Stacks are pulled into the cloud and site composes via the Compose Spec `include:` directive. Each stack is also runnable standalone for testing.
|
|
|
|
## Quick start
|
|
|
|
```bash
|
|
# Cloud hub (run on the central server)
|
|
cd cloud
|
|
cp .env.example .env # fill in real secrets
|
|
docker compose up -d
|
|
|
|
# A plant edge (run on the edge gateway at the plant)
|
|
cd sites/<plant>
|
|
cp .env.example .env
|
|
docker compose up -d
|
|
```
|
|
|
|

## Design
|
|
|
|
See [`docs/architecture.md`](docs/architecture.md) for the hub-and-spoke topology, 4-network model, ingress table, and the reasoning behind each choice.
|
|
|
|
## Conventions
|
|
|
|
- kebab-case folder names
|
|
- `compose.yml` (Compose Spec), not `docker-compose.yml`
|
|
- Stack composes pulled into cloud/site via `include:`
|
|
- Secrets in `.env` files (gitignored); `.env.example` committed with placeholders
|
|
- OT layer (OPCUA, PLCs) is **out of scope** for this repo
