Referência

https://docs.n8n.io/hosting/installation/server-setups/docker-compose/#5-create-docker-compose-file

Passo 1

cd /root
mkdir n8n
vim docker-compose.yml

Passo 2 – Configuração docker-compose.yml

version: "3.7"
services:
  n8n:
    image: docker.n8n.io/n8nio/n8n
    restart: always
    ports:
      - "127.0.0.1:5678:5678"
    environment:
      - N8N_HOST=${SUBDOMAIN}.${DOMAIN_NAME}
      - N8N_PORT=5678
      - N8N_PROTOCOL=https
      - NODE_ENV=production
      - WEBHOOK_URL=https://${SUBDOMAIN}.${DOMAIN_NAME}/
      - GENERIC_TIMEZONE=${GENERIC_TIMEZONE}
    volumes:
      - ./n8n_data:/home/node/.n8n
volumes:
  n8n_data:
    external: true

Passo 3 – Configuração .env

# DOMAIN_NAME and SUBDOMAIN combined decide where n8n will be reachable from
# above example would result in: https://n8n.example.com

# The top level domain to serve from
DOMAIN_NAME=cuidadodigital.com.br

# The subdomain to serve from
SUBDOMAIN=n8n

# Optional timezone to set which gets used by Cron-Node by default
# If not set New York time will be used
GENERIC_TIMEZONE=America/Sao_Paulo

# The email address to use for the SSL certificate creation
#SSL_EMAIL=user@example.com

Passo 4 – Finalizando n8n

docker-compose up -d
docker-compose stop
chmod -R 777 n8n_data

CONFIGURAÇÃO NGNIX

cd /etc/nginx/sites-enabled
vim n8n.conf

Passo 5 – Configurando  Virtual Host / Proxy Reverso

server {
  server_name n8n.minhaempresa.com.br;
  set $upstream 127.0.0.1:5678;
  underscores_in_headers on;
  location /.well-known {
    alias /var/www/ssl-proof/minhaempresa/.well-known;
  }

  location / {
    proxy_pass_header Authorization;
    proxy_pass http://$upstream;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Forwarded-Ssl on; # Optional

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    proxy_http_version 1.1;
    proxy_set_header Connection “”;
    proxy_buffering off;

    client_max_body_size 0;
    proxy_read_timeout 36000s;
    proxy_redirect off;
  }
}

Passo 6 – Testar Conf – Reiniciar serviço

nginx -t
systemctl reload nginx

Passo 7 – Gerar Certificado via Certbot

mkdir -p /var/www/ssl-proof/minhaempresa.com.br/.well-known
certbot --webroot -w /var/www/ssl-proof/minhaempresa/ -d n8n.minhaempresa.com.br -i nginx
