1. VPS Purchase and Initial Configuration
Choosing a Host
There are several reputable VPS providers:
- Hetzner
- Netcup (recommended)
- OVH
- Scaleway
- Contabo
For this tutorial, we recommend Hetzner or Netcup for their excellent value for money.
Recommended Minimum Configuration
To run Coolify comfortably, choose at minimum:
- 2 CPU cores
- 4 GB RAM
- 40 GB SSD storage
First Connection
After purchasing your VPS, you'll receive by email:
- Your server's IP address
- The initial root password
Connect via SSH:
ssh root@your_ip
Initial System Update
apt update && apt upgrade -y
Installing essential packages:
apt install 2. Domain Name Configuration with Cloudflare
-
Create an account on Cloudflare.com
-
Add your domain to Cloudflare
-
In the DNS section, add two A records:
First record (main domain):
- Type: A
- Name: coolify (or your chosen subdomain, or your main domain)
- Content: Your_VPS_IP
- Proxy status: Disabled (gray icon)
Second record (wildcard for subdomains):
- Type: A
- Name: * (asterisk)
- Content: Your_VPS_IP
- Proxy status: Disabled (gray icon)
This wildcard configuration (
*.your-domain.com) will allow Coolify to automatically create subdomains for each of your deployed applications. For example:- app1.your-domain.com
- api.your-domain.com
- staging.your-domain.com
- etc.
All these subdomains will automatically point to your VPS server, and Coolify will handle routing traffic to the correct application based on the subdomain used.
3. Server Security Setup
Creating a Non-Root User
SSH Keys Configuration
