6 Pillars of a ProductionDocker Setup

Deploy on Push

Connect your GitHub, GitLab, or Bitbucket repositories and get automatic deployments on every `git push`. Coolify handles the webhooks, builds the images, and updates the containers with zero downtime.

ssh root@198.51.100.42Ubuntu

Welcome to Ubuntu.

Nixpacks Under the Hood

Say goodbye to writing Dockerfiles. Coolify uses Nixpacks to auto-detect your stack (Node, Python, Go, Rust, PHP) and build optimized, secure OCI images automatically.

Built-in Traefik Proxy

Coolify automatically configures Traefik to route traffic to your applications and provisions free SSL/TLS certificates via Let's Encrypt. No more messing with nginx config files.

One-Click Databases

Spin up PostgreSQL, MySQL, Redis, MongoDB, and more with a single click. Coolify handles the persistence, environment variables, and internal networking out of the box.

Resource Monitoring

Keep an eye on your CPU, memory, and disk usage directly from the Coolify dashboard. Identify bottlenecks and scale your applications before they go down.

Bring Your Own Server (BYOS)

Coolify doesn't lock you in. If you outgrow a server, simply attach a new VPS to your Coolify instance via SSH and seamlessly distribute your workloads across multiple nodes.

TL;DR (Quick Answer)

What is an Ubuntu VPS for Coolify?

It's a dedicated KVM-virtualized Linux server perfectly suited for running Coolify—an open-source, self-hosted Heroku and Netlify alternative. You bring the raw compute, and Coolify transforms it into an intelligent PaaS that handles git deployments, SSL certificates, and database management automatically.

Who should use it?

Developers, agencies, and homelabbers who are tired of paying exorbitant per-seat or resource-based pricing on platforms like Heroku, Vercel, or Render.

Ubuntu

Why Ubuntu?

Coolify officially targets Ubuntu 22.04 and 24.04 as its primary installation environment. Running on the recommended OS guarantees zero friction during install and updates.

When to choose it?

When you want the developer experience of "git push to deploy" but you want to own your infrastructure, data, and retain the freedom to scale out to multiple servers.

Traefik Proxy
Auto-routes traffic & terminates SSL via Let's Encrypt.
Next.js App (Nixpacks)
Built automatically on git push without a Dockerfile.
Managed PostgreSQL
Persistent storage, isolated network, automated backups.
Coolify Control Plane
Manages Docker daemon, networks, webhooks, and the dashboard.
System Architecture

The Anatomy of a Coolify Host

Coolify isn't just a dashboard—it orchestrates an entire platform-as-a-service architecture on top of a raw Ubuntu VPS.

  • Traefik Reverse ProxyAutomatically spins up and routes incoming traffic to your containers. Let's Encrypt certificates are negotiated and renewed automatically without manual intervention.
  • Nixpacks Build EngineWhen you push to GitHub, Coolify receives the webhook, spins up a Nixpacks build container, analyzes your code, and creates an optimized Docker image. No Dockerfiles needed.
  • Docker BackendUnderneath the PaaS magic, everything is just standard Docker containers. If Coolify ever goes down, your applications continue running independently.
Developer Experience

Git Push to Deploy

Connect your repository, push to the main branch, and watch Coolify automatically pull, build, and deploy your application with zero downtime.

Platform Comparison

Why Not Use Managed PaaS?

You love the "git push to deploy" experience of Vercel and Heroku, but the database pricing and bandwidth limitations eventually catch up to you. Coolify offers a way out.

Managed PaaS (Heroku/Render)

  • Zero server maintenance
  • Push to deploy workflows
  • Exorbitant database pricing
  • Per-developer seat costs
  • Background job time limits
THE SWEET SPOT

Coolify on VPS

  • Push to deploy workflows
  • Unlimited apps & databases
  • Fixed, flat monthly hosting cost
  • Bring your own hardware
  • Open-source & self-hosted

Raw Docker VPS

  • Total control over daemon
  • Minimal resource overhead
  • Manual Traefik/Nginx setup
  • Must write own Dockerfiles
  • No built-in webhook deployments

Unrestricted Performance

When you use a managed PaaS, your background jobs and build times are strictly limited (often to 15 or 30 minutes). If your Next.js application has thousands of static pages, building it can easily hit these timeouts.

With Coolify on a dedicated KVM VPS, your build processes have full, unrestricted access to the underlying CPU cores and NVMe storage. Build times are limited only by the hardware you rent.

Internal Networks & Security

In a typical VPS setup, exposing your database to the internet is a massive security risk. Coolify automatically creates private, internal Docker networks.

Your Postgres or Redis databases are accessible only to your applications via internal hostnames. By default, Coolify does not publish database ports to the host machine, ensuring your data remains completely shielded from port scanners.

Zero Friction Setup

Installed in 60 Seconds

Coolify completely abstracts away the complexity of setting up Docker, internal networks, and reverse proxies.

As long as you are running a clean Ubuntu 22.04 or 24.04 instance, you simply SSH in as root and run the official convenience script.

Note: Do not run this script on a server that already has a web server (like Apache or Nginx) running, as Traefik needs to bind to port 80 and 443.

1. SSH as Root

Log into your new FlashRDP VPS.

Terminal
ssh root@your_server_ip

2. Execute the Script

Run the automated installer which installs Docker and pulls the Coolify images.

Root Shell
curl -fsSL https://cdn.coollabs.io/coolify/install.sh | bash

Technical FAQ

Coolify provides the same developer experience—git push to deploy, automatic PR previews, and managed databases—without the exorbitant per-seat or resource pricing.

Instead of paying $25/month for a 1GB database on a managed PaaS, you can rent an 8GB VPS for a fraction of the cost, install Coolify, and run dozens of databases and applications on it. You bring the hardware, and Coolify provides the PaaS abstraction layer.
