Show HN: DockerHoster – Self-hosted alternative to Vercel with auto-deployments

Description and use

DockerHoster lets you host 20+ sites on a single $12/month VPS with automated GitHub deployments, full Docker support, and no serverless limitations.

Problem

High per-project hosting fees and serverless limitations for databases, cronjobs, and long-running processes.

Outcome

DockerHoster enables cost-effective, scalable self-hosting of multiple sites with automated deployments, full Docker ecosystem access, and no serverless limitations.

Workflow

• 1. Spin up a VPS (e.g., DigitalOcean droplet).
• 2. Install Docker and Docker Compose.
• 3. Deploy DockerHoster by running the provided one-command setup.
• 4. Add nginx-proxy and configure VIRTUAL_HOST labels in docker-compose.yml for each site.
• 5. Copy the GitHub Actions workflow and docker-compose.yml into each project repository.
• 6. Push code to GitHub; GitHub Actions triggers DockerHoster to rebuild and redeploy containers automatically.
• 7. Use Cloudflare for DNS, SSL, DDoS protection, and WAF.
• 8. Manage databases, cronjobs, and long-running processes within Docker containers as needed.

Evidence

It’s a one-command setup that lets you host 20+ websites on a single $12/month VPS with automated GitHub deployments.
