 ## 4) Subir a stack com Docker Compose
 
+### Alternativa principal (com domínio + HTTPS automático via Caddy)
+
+Agora que o domínio está apontando para o servidor, use `docker-compose.domain.yml` para publicar em **HTTPS** com certificado automático (Let's Encrypt).
+
+1. Ajuste o `.env` na pasta da API:
+
+```env
+DOMAIN=linegestao.inglinesystems.com.br
+ACME_EMAIL=seu-email@dominio.com
+FRONTEND_PUBLIC_URL=https://linegestao.inglinesystems.com.br
+APP_USE_HTTPS_REDIRECTION=false
+```
+
+2. Libere portas públicas no firewall (uma vez):
+
+```bash
+sudo ufw allow 80/tcp
+sudo ufw allow 443/tcp
+```
+
+3. Suba stack com Caddy:
+
+```bash
+cd ~/apps/line-gestao-api
+docker compose -f docker-compose.domain.yml up -d --build
+```
+
+4. Valide certificado e API em HTTPS:
+
+```bash
+curl -Iv https://linegestao.inglinesystems.com.br/health
+```
+
+Resultado esperado:
+- status `HTTP/2 200`
+- certificado emitido para `linegestao.inglinesystems.com.br`
+
+> Importante: no primeiro boot o Caddy pode levar alguns segundos para obter o certificado. Se falhar, confira se DNS já propagou e se as portas 80/443 estão acessíveis.
+
+Comandos úteis de diagnóstico:
+
+```bash
+docker compose -f docker-compose.domain.yml logs -f caddy
+docker compose -f docker-compose.domain.yml logs -f api
+```
+
 ### Alternativa A (provisória e mais rápida): sem Caddy, expondo API direto
 
 Se você ainda não tem acesso ao DNS/domínio no Wix, use o arquivo `docker-compose.prod.yml` deste repositório para publicar só a API (porta `8080`) e o banco.
