Initial structure for R&D infrastructure:
- stacks/ — 13 reusable, runnable stack stubs (kebab-case)
cloud-and-edge: node-red, influxdb, grafana, keycloak, portainer,
nginx-proxy, mqtt, postfix
cloud-only: wireguard-server, gitea, jenkins, sql (postgres stub)
edge-only: wireguard-client
- cloud/ — single central hub composition with 4 networks
(edge, app, data internal, mgmt) and include: stubs
- sites/ — per-plant edge folders (template README only for now)
- docs/architecture.md — hub-and-spoke + ingress + segmentation rationale
Network model: only nginx-proxy (80/443/8883) and wireguard-server
(51820/udp) publish ports on the cloud host. Edge nginx publishes
80/443 on plant-LAN interface only. MQTT cloud-side via nginx stream
proxy; MQTT edge-side internal-only; Postfix outbound-only.
OT layer (OPCUA, PLCs) is out of scope for this repo.

postfix
Outbound-only SMTP relay. Used by grafana alerts, node-red flows, jenkins build notifications.
- Network:
app(internal services hitsmtp://postfix:25) - Ingress: none — no port published, no listener facing internet
- Egress: TCP/25 outbound to internet MX servers (or a smart-host relay)
- TODO: SPF/DKIM/DMARC for
${POSTFIX_FROM_DOMAIN}, smart-host config if WBD provides a relay
