# Deploy en VPS (Hetzner) — Arb Pulse
|
||||
|
||||
Despliegue con Docker Compose: el contenedor `app` (Node + tsx) detrás de
|
||||
`caddy`, que emite HTTPS automáticamente (Let's Encrypt). Pensado para correr
|
||||
24/7 desde la rama `main`.
|
||||
Despliegue con Docker Compose para correr 24/7 desde la rama `main`. El contenedor
|
||||
`app` (Node + tsx) queda en `127.0.0.1:8080` y un **reverse proxy del host** expone
|
||||
HTTPS. Dos modos:
|
||||
|
||||
- **Opción A — detrás de nginx existente (recomendado en este VPS).** El servidor ya
|
||||
corre nginx en 80/443 con certbot para otras apps (p. ej. `consumet.wayool.com`,
|
||||
`openclaw.wayool.com`). Se agrega un vhost para `arbpulse.wayool.com` y punto.
|
||||
- **Opción B — Caddy bundleado.** Solo para un server **fresco** sin nada en 80/443.
|
||||
|
||||
## Prerrequisitos
|
||||
|
||||
1. VPS Ubuntu/Debian (recomendado 2 vCPU / 2 GB RAM — p. ej. Hetzner CX22).
|
||||
2. Subdominio en Cloudflare (zona `wayool.com`): `arbpulse.wayool.com` con un
|
||||
registro **A → IP del VPS**. Ver "DNS en Cloudflare" abajo.
|
||||
3. Puertos abiertos:
|
||||
```bash
|
||||
sudo ufw allow 22 && sudo ufw allow 80 && sudo ufw allow 443 && sudo ufw --force enable
|
||||
```
|
||||
2. Subdominio `arbpulse.wayool.com` con registro **A → IP del VPS** (ya creado en
|
||||
Cloudflare, ver abajo).
|
||||
3. Docker + plugin compose (el `deploy.sh` los instala si faltan).
|
||||
|
||||
## DNS en Cloudflare (zona wayool.com)
|
||||
|
||||
El dominio `wayool.com` está gestionado por Cloudflare. La app se sirve en el
|
||||
subdominio **`arbpulse.wayool.com`**.
|
||||
- Registro **A**, nombre `arbpulse`, contenido = IP del VPS, **"DNS only" (nube gris)**.
|
||||
- Motivo: certbot/Caddy emiten el cert vía HTTP-01 (reto directo al origen) y el
|
||||
SSE de `/api/stream` fluye sin buffering del proxy de Cloudflare.
|
||||
- Verificar: `dig +short arbpulse.wayool.com` debe devolver la IP del VPS.
|
||||
|
||||
- Registro: **A**, nombre `arbpulse`, contenido = IP pública del VPS.
|
||||
- **Proxy: "DNS only" (nube gris), NO proxied (nube naranja).**
|
||||
- Motivo: Caddy emite el cert Let's Encrypt vía HTTP-01 (requiere que el reto en
|
||||
el puerto 80 llegue directo al origen), y el stream SSE de `/api/stream` fluye
|
||||
sin el buffering/timeout del proxy de Cloudflare.
|
||||
- Si más adelante querés proxear con Cloudflare (naranja) para ocultar la IP,
|
||||
hay que cambiar Caddy a challenge DNS-01 (plugin `caddy-dns/cloudflare` + token
|
||||
de API) y poner SSL/TLS en "Full (strict)". No es necesario para arrancar.
|
||||
- Verificar propagación: `dig +short arbpulse.wayool.com` debe devolver la IP del
|
||||
VPS antes de que Caddy pida el certificado.

## Deploy (para el agente del VPS)
|
||||
## Opción A — detrás del nginx existente (recomendado)
|
||||
|
||||
Todo lo hace el script idempotente `deploy.sh` (instala Docker si falta, clona o
|
||||
actualiza el repo, y levanta los contenedores). Es seguro re-ejecutarlo.
|
||||
No toca tus otras apps ni Caddy. Solo levanta el contenedor `app` en loopback y le
|
||||
pone un vhost de nginx con certbot (mismo patrón que consumet/openclaw).
|
||||
|
||||
```bash
|
||||
# 1) Traer el script y ejecutarlo (primera vez: crea .env y se detiene)
|
||||
# 1) Traer y correr el script (1ra vez: crea .env y se detiene). App-only por default.
|
||||
curl -fsSL https://raw.githubusercontent.com/mauricioabh/arbpulse/main/deploy/deploy.sh -o /tmp/arbpulse-deploy.sh
|
||||
bash /tmp/arbpulse-deploy.sh
|
||||
|
||||
# 2) Editar el .env con el dominio y secretos
|
||||
nano /opt/arbpulse/deploy/.env # DOMAIN=... ; SENTRY_DSN=... (opcional) ; UPSTASH_* (opcional)
|
||||
# 2) Editar el .env (DOMAIN + secretos opcionales)
|
||||
nano /opt/arbpulse/deploy/.env # DOMAIN=arbpulse.wayool.com ; SENTRY_TRACING=false ; ...
|
||||
|
||||
# 3) Volver a ejecutar para construir y arrancar
|
||||
# 3) Volver a correr: build + up del contenedor app (127.0.0.1:8080)
|
||||
bash /tmp/arbpulse-deploy.sh
|
||||
|
||||
# 4) Instalar el vhost de nginx y emitir el cert
|
||||
sudo cp /opt/arbpulse/deploy/nginx/arbpulse.wayool.com.conf /etc/nginx/sites-available/arbpulse.wayool.com
|
||||
sudo ln -s /etc/nginx/sites-available/arbpulse.wayool.com /etc/nginx/sites-enabled/
|
||||
sudo nginx -t && sudo systemctl reload nginx
|
||||
sudo certbot --nginx -d arbpulse.wayool.com
|
||||
```
|
||||
|
||||
Alternativa (si ya está clonado el repo en `/opt/arbpulse`):
|
||||
El vhost (`deploy/nginx/arbpulse.wayool.com.conf`) trae `proxy_buffering off` y
|
||||
timeouts largos para que el SSE funcione. certbot copia el bloque `location` al
|
||||
server TLS que genera, así que los ajustes SSE se mantienen en HTTPS.
|
||||
|
||||
## Opción B — Caddy bundleado (server fresco, sin nginx)
|
||||
|
||||
Solo si nada más usa 80/443:
|
||||
|
||||
```bash
|
||||
cd /opt/arbpulse/deploy
|
||||
cp .env.vps.example .env && nano .env # solo la primera vez
|
||||
docker compose up -d --build
|
||||
cp .env.vps.example .env && nano .env # DOMAIN=arbpulse.wayool.com ...
|
||||
WITH_CADDY=1 bash /tmp/arbpulse-deploy.sh # o: docker compose --profile caddy up -d --build
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Verificar
|
||||
|
||||
```bash
|
||||
docker compose -f /opt/arbpulse/deploy/docker-compose.yml ps
|
||||
curl -s http://127.0.0.1:8080/api/health # local
|

|
||||
curl -s https://arbpulse.wayool.com/api/health # público (HTTPS)

## Notas
|
||||
|
||||
- Caddy usa `flush_interval -1` para que el SSE (`/api/stream`) fluya en tiempo
|
||||
real; no comprimir `text/event-stream`.
|
||||
- El puerto 8080 se publica solo en `127.0.0.1` (no expuesto a Internet); el
|
||||
tráfico público entra por Caddy (80/443).
|
||||
- Región: Hetzner no tiene Asia; para menor latencia a Binance/Bybit/OKX evalúa
|
||||
un VPS en Singapur. Para Kraken (EU) Falkenstein/Helsinki va bien.
|
||||
- El puerto 8080 se publica solo en `127.0.0.1` (no expuesto a Internet); el tráfico

|

- La app ya envía `X-Accel-Buffering: no` en el SSE, que nginx respeta para no
|

bufferear ese response.
