Coolify (your own PaaS)

​

Requirements

• OS – Ubuntu 22.04.
• RAM – 2 GB for Coolify itself plus room for apps, 4 GB and up is comfortable: VPS-2 or higher. On 1 GB Coolify is unstable and crashes during builds.
• Docker – no need to install it beforehand, the installer sets up its own. Docker from snap is not supported: remove it before installing.
• Ports 80, 443, 8000 – must be free. If nginx, Apache, or another panel holds them, the Coolify proxy will not start: stop them, remove them, or move them to another port.

​

Installation

1. SSH – connect to the server (Connection):
   ssh root@YOUR_SERVER_IP
   
2. Installer – installs Docker Engine, the dependencies, and Coolify into /data/coolify:
   curl -fsSL https://cdn.coollabs.io/coolify/install.sh | sudo bash
   
   It takes a few minutes, at the end the script prints the dashboard address.
3. Admin – open http://SERVER_IP:8000 and create the first account: it becomes the owner.

​

Ports

• 8000 – the Coolify dashboard.
• 80, 443 – HTTP and HTTPS for apps, SSL issuance.
• 6001, 6002 – realtime updates and the web terminal.

ufw allow 8000/tcp
ufw allow 80/tcp
ufw allow 443/tcp
ufw allow 6001/tcp
ufw allow 6002/tcp

​

Domain and SSL

1. A record – point a domain at the server IP, for example coolify.yourdomain.ru: DNS records.
2. Domain in Coolify – Settings → Configuration → the Instance’s Domain (FQDN) field → https://coolify.yourdomain.ru → Save. Write the address with https://.
3. SSL – Coolify sets up the reverse proxy (Traefik), gets a Let’s Encrypt certificate, and renews it.

​

First deploy

1. Project – + New → Project, with an environment inside, Production by default.
2. Resource – + New Resource → a source: a Git repository (public or private), a Docker image, or Docker Compose. Coolify builds and runs it.
3. Deploy – the app domain with https:// → Deploy. After that every push deploys with a button or automatically via webhook.
