How do I self-host this Vercel domain management template using Coolify or another self-hosting platform?

[fiqryq]

I am using default script for domain management with Vercel, including adding, removing, and verifying domains. I would like to self-host the same functionality using Coolify or another self-hosting provider. Could you guide me on the following?

• Self-hosting with Coolify: What are the steps to deploy this template in Coolify (or other self-hosting platforms)?
• Custom Domain Configuration: How can I modify the configuration in this template to use a custom domain instead of a Vercel-provided domain?
• Environment Variables: How should I handle environment variables like PROJECT_ID_VERCEL, TEAM_ID_VERCEL, and AUTH_BEARER_TOKEN when migrating this template to a self-hosted environment?
