Deploy Production

Deploy Production Skill

Quando usare questa skill

• Deploy di qualsiasi progetto su VPS Linux con Docker Compose
• Troubleshooting container Docker in produzione
• Setup nuovo progetto su VPS esistente
• Migrazione tra VPS

Infrastruttura VPS (esempio di organizzazione multi-VPS)

Adatta la tabella al tuo setup. La logica della skill è agnostica rispetto al provider.

REGOLA FONDAMENTALE

deploy.sh è LOCALE (sul PC Windows), NON sul VPS!

Workflow Deploy Standard

1. Pre-deploy: Commit e Push

# SEMPRE: modifiche devono essere su Git PRIMA del deploy
cd D:/progetti/PROGETTO
git add -A && git commit -m "fix: descrizione" && git push origin main

2. Scelta Flag Deploy

# Solo backend (PHP/Node.js) — 15 secondi
./deploy.sh --backend-only

# Solo frontend (Vue/React rebuild) — 30-60 secondi
./deploy.sh --frontend-only

# Full deploy (entrambi) — 1-2 minuti
./deploy.sh

# Nuove dipendenze (composer/npm install) — 3-5 minuti
./deploy.sh --no-cache

# REGOLA: NON usare --no-cache per semplici modifiche codice!

3. Post-deploy: Verifica

# VPS_PORT="<porta-ssh>" (es. 22 o porta custom del VPS)

# Provider A (fish shell — SEMPRE bash -c)
ssh -p "$VPS_PORT" root@<VPS_A_IP> "bash -c 'cd /root/PROGETTO && docker compose ps'"

# Provider B (bash diretto)
ssh -p "$VPS_PORT" root@<VPS_B_IP> "cd /opt/PROGETTO && docker compose ps"

# Verifica logs
ssh -p "$VPS_PORT" root@VPS_IP "bash -c 'docker logs CONTAINER --tail 50'"

# Test endpoint
curl -s https://api.DOMINIO.com/api/health

Troubleshooting

Container non parte

# Controlla logs
docker logs CONTAINER --tail 100

# Controlla risorse
docker stats --no-stream

# Ricostruisci da zero
docker compose down && docker compose up -d --build

Errore 502 Bad Gateway

# Backend non raggiungibile da Traefik
# 1. Verifica che il container backend sia running
docker ps | grep backend

# 2. Verifica network Docker
docker network inspect PROGETTO_default

# 3. Verifica labels Traefik
docker inspect CONTAINER | grep traefik

SSL non funziona

# Verifica acme.json
ls -la /letsencrypt/acme.json

# Se corrotto, rigenerare
rm /letsencrypt/acme.json
docker compose restart traefik
# Aspettare 1-2 minuti per nuovo certificato

Frontend non aggiornato

Le variabili VITE_* sono BAKED nel bundle durante build.
Modifiche .env frontend richiedono: ./deploy.sh --frontend-only
Solo git pull NON basta per il frontend!
