Wire up the three foundation stacks (nginx-proxy, sql, portainer) in cloud/compose.yml and add real configs for the first two. nginx-proxy - Base nginx.conf with http + stream contexts, modern TLS profile, client_max_body_size baseline for gitea LFS / mlflow artifacts. - Vhosts under conf.d/: grafana, gitea, keycloak, nodered, mlflow, jupyter, portainer (HTTPS upstream), rabbitmq, jenkins. WebSocket upgrade headers where needed (grafana live, node-red editor, jupyterhub kernels, jenkins agents). - conf.d/00-default.conf serves /.well-known/acme-challenge/ on :80 and 301-redirects everything else. - stream.d/mqtt.conf terminates MQTT-TLS at 8883, proxies to rabbitmq:1883 internally. - All vhosts reference /etc/letsencrypt/live/infra/* — a stable path via certbot --cert-name infra, so the wildcard migration changes nothing in the vhost files. - README documents: HTTP-01 SAN interim during Versio period → DNS-01 wildcard via certbot-dns-transip after migration; bootstrap procedure (self-signed fallback → real cert issuance → reload). sql - config/init.d/01-databases.sh provisions gitea/keycloak/mlflow databases + roles on first start. Idempotent only via fresh data volume — change the script after first run requires manual psql or a volume wipe. - compose env extended with GITEA_DB_PASSWORD, KEYCLOAK_DB_PASSWORD, MLFLOW_DB_PASSWORD. cloud - include: now wires nginx-proxy + sql + portainer. Other stacks stay commented for future rounds. - .env.example adds KEYCLOAK_DB_PASSWORD and sensible defaults (LETSENCRYPT_EMAIL, GRAFANA_ROOT_URL, KEYCLOAK_HOSTNAME, GITEA_ROOT_URL, POSTFIX_FROM_DOMAIN all pointing at wbd-rd.nl). - Operator note inline: bring portainer's standalone instance down before deploying via cloud compose; comment its ports: block.

# nginx-proxy
|
|
|
|
The single web ingress for cloud + edge. Reverse-proxies HTTPS UIs and stream-proxies MQTT-TLS to RabbitMQ. TLS certs managed by a certbot sidecar (Let's Encrypt).
|
|
|
|
- **Image**: stock `nginx:1.27-alpine` (we don't use `nginxproxy/nginx-proxy` because we need the `stream {}` context for MQTT-TLS)
|
|
- **Sidecar**: `certbot/certbot:latest` — renews every 12h via HTTP-01 webroot challenges
|
|
- **Networks**: `edge` (the only port-publisher) + `app` (talks to upstream services)
|
|
- **Host ports**: `tcp/80`, `tcp/443`, `tcp/8883`
|
|
|
|
## Cert strategy
|
|
|
|
**Interim (Versio DNS)**: HTTP-01 SAN cert covering all subdomains, issued via `--webroot`. Requires:
|
|
- Public DNS A records for each subdomain pointing at the cloud host
|
|
- `tcp/80` reachable from the internet
|
|
|
|
**After TransIP migration**: switch to DNS-01 wildcard (`*.wbd-rd.nl`). Swap the `certbot/certbot` image for a build that includes `certbot-dns-transip` and reissue with `--cert-name infra` so the cert path stays stable — **no vhost config changes needed**.

## Config layout
|

|
|
```
|
|

```
|
|
|
|
Volumes:
|
|
- `nginx-certs` — Let's Encrypt cert chains at `/etc/letsencrypt/`; read-only into nginx, writable from certbot
|
|
- `nginx-acme-challenge` — webroot for HTTP-01 challenges at `/var/www/certbot/`
|
|
|
|
All vhosts reference `/etc/letsencrypt/live/infra/fullchain.pem` and `privkey.pem` — a stable path independent of the issuance method.
|
|
|
|
## First-run bootstrap
|
|
|
|
The HTTPS server blocks won't load without a cert at `/etc/letsencrypt/live/infra/`. Bootstrap procedure (one-time):
|
|
|
|
```bash
|
|
cd stacks/nginx-proxy
|
|
|
|
# 1. Self-signed fallback so nginx starts and serves /.well-known/acme-challenge/
|
|
docker compose run --rm --entrypoint=/bin/sh nginx -c \
|
|
"mkdir -p /etc/letsencrypt/live/infra && \
|
|
openssl req -x509 -nodes -days 1 -newkey rsa:2048 \
|
|
-keyout /etc/letsencrypt/live/infra/privkey.pem \
|
|
-out /etc/letsencrypt/live/infra/fullchain.pem \
|
|
-subj '/CN=bootstrap-infra'"
|
|
|
|
# 2. Start nginx (HTTPS blocks load with the dummy cert)
|
|
docker compose up -d nginx
|
|
|
|
# 3. Issue the real cert via HTTP-01
|
|
docker compose run --rm certbot certonly \
|
|
--webroot -w /var/www/certbot \
|
|
--email "$LETSENCRYPT_EMAIL" --agree-tos --no-eff-email \
|
|
--cert-name infra \
|
|
-d grafana.wbd-rd.nl -d gitea.wbd-rd.nl -d keycloak.wbd-rd.nl \
|
|
-d nodered.wbd-rd.nl -d mlflow.wbd-rd.nl -d jupyter.wbd-rd.nl \
|
|
-d portainer.wbd-rd.nl -d rabbitmq.wbd-rd.nl -d jenkins.wbd-rd.nl \
|
|
-d mqtt.wbd-rd.nl
|
|
|
|
# 4. Reload nginx to pick up the real cert
|
|
docker compose exec nginx nginx -s reload
|
|
```
|
|
|
|
The certbot sidecar then renews every 12h automatically.
|
|
|
|
## DNS prereqs (HTTP-01)
|
|
|
|
Before bootstrap, ensure A records exist in Versio for:
|
|
|
|
```
|
|
grafana.wbd-rd.nl A <cloud-public-ip>
|
|
gitea.wbd-rd.nl A <cloud-public-ip>
|
|
keycloak.wbd-rd.nl A <cloud-public-ip>
|
|
nodered.wbd-rd.nl A <cloud-public-ip>
|
|
mlflow.wbd-rd.nl A <cloud-public-ip>
|
|
jupyter.wbd-rd.nl A <cloud-public-ip>
|
|
portainer.wbd-rd.nl A <cloud-public-ip>
|
|
rabbitmq.wbd-rd.nl A <cloud-public-ip>
|
|
jenkins.wbd-rd.nl A <cloud-public-ip>
|
|
mqtt.wbd-rd.nl A <cloud-public-ip>
|
|
```
|
|
|
|
## TODO
|
|
|
|
- Wildcard cert via `certbot-dns-transip` (post TransIP migration)
|
|
- OIDC `auth_request` to Keycloak in front of services without native OIDC (mlflow, portainer-CE)
|
|
- Edge-side variant: bind to plant-LAN IP, internal CA for `*.local` hostnames
|
|
- HSTS + security headers (`add_header Strict-Transport-Security ...`)
