Setting up VPS with Docker, N8N, Postgres, and Nextcloud for workflow and CorelDRAW

VPS server (Contabo) with already installed infrastructure.

Tasks:

1. Update Node.js to version 20.x–24.x

2. Rebuild the N8N container to work with HTTPS

3. Configure and check all Docker containers (N8N, Postgres, Qdrant, Proxy Manager, Portainer)

4. Set up Nextcloud for CorelDRAW files from two workstations, with synchronization and backups

5. Check access, ports, Docker networks, Proxy, and Cloudflare

6. Ensure full functionality of all services and backup

Permissions:

• The freelancer is granted full sudo / root access to perform all tasks.

• After the work is completed, access can be changed or removed.

• 🛠 What is already installed on the server

  🌍 DNS / Cloudflare

  • All A records, MX, NS, and TXT are configured

  • HTTPS for N8N is currently not working (container needs to be rebuilt)

• ---

  💾 Nextcloud — CorelDRAW files

  Goal: centralized storage from two workstations

  • Install Nextcloud on VPS (Docker)

  • Create a folder: /Corel_Projects/

  • Desktop Client on PC: C:\LaserPatch\Corel\

  • Set up automatic synchronization and backups

  • File version control

  • In the future — link files to orders in the Postgres database (N8N workflow)
