Install n8n: your own automation server (Docker + automatic SSL)

Steps

1. 1Add the DNS record

   Point the subdomain to the server IP. Caddy can't get a certificate before the record propagates.

   Copy

   # DNS: n8n.example.com  A  SUNUCU_IP
   dig +short n8n.example.com

2. 2Compose file

   Define the n8n and Caddy services. Replace example.com with your domain.

   Copy

   mkdir -p ~/n8n && cd ~/n8n
   cat > compose.yaml <<'EOF'
   services:
     n8n:
       image: docker.n8n.io/n8nio/n8n
       restart: unless-stopped
       environment:
         - N8N_HOST=n8n.example.com
         - N8N_PROTOCOL=https
         - WEBHOOK_URL=https://n8n.example.com/
         - GENERIC_TIMEZONE=Europe/Istanbul
         - TZ=Europe/Istanbul
       volumes:
         - n8n_data:/home/node/.n8n
     caddy:
       image: caddy:2
       restart: unless-stopped
       ports:
         - "80:80"
         - "443:443"
       volumes:
         - ./Caddyfile:/etc/caddy/Caddyfile
         - caddy_data:/data
   volumes:
     n8n_data:
     caddy_data:
   EOF

3. 3Caddy configuration

   Caddy forwards HTTPS requests to the n8n container.

   Copy

   cat > Caddyfile <<'EOF'
   n8n.example.com {
       reverse_proxy n8n:5678
   }
   EOF

4. 4Start and create the owner account

   When the services are up, open https://n8n.example.com and create the owner account right away.

   Copy

   docker compose up -d
   docker compose logs -f caddy
