How to Install Coolify on Ubuntu 26.04

---

Coolify is an open-source, self-hosted Heroku/Netlify alternative that helps you deploy and manage applications, databases, and services with ease. It comes with a simple web dashboard and supports multiple app stacks.

NOTE: Ubuntu 26.04 LTS (Resolute Raccoon) was released in April 2026 and is supported until April 2031. Coolify's current documentation recommends LTS releases for automated installation.

Prerequisites Checklist 📝

---

• Server: A clean instance of Ubuntu 26.04 LTS
• Resources: Minimum 2 CPU cores, 2GB RAM, and 10GB free disk space. Additional resources are recommended for running multiple applications.
• Architecture: amd64 or arm64
• Access: Logged in as the root user or a user with sudo privileges
• Ports: Ensure 22, 80, 443, and 8000 are open in your firewall

Prepare the Server & Firewall 🛡️

---

Update your system and install curl:

sudo apt update && sudo apt upgrade -y
sudo apt install curl -y

Configure the firewall (UFW) to allow the necessary ports:

# Allow SSH, HTTP, HTTPS, and Coolify Dashboard
sudo ufw allow 22/tcp
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw allow 8000/tcp

# Enable the firewall
sudo ufw enable

Check the firewall status:

sudo ufw status

Run the Quick Installation Script

---

Coolify provides an automated installation script that installs and configures the required components:

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

The installation may take several minutes. Wait for the installer to complete and display the Coolify dashboard URL.

IMPORTANT: Use a fresh Ubuntu server whenever possible. Existing Docker installations, applications, or services can cause conflicts during installation.

Verify the Installation

---

After the installation finishes, check that the Coolify container is running:

docker ps --filter name=coolify

You can also check the Coolify logs:

docker logs coolify --tail 50

If the installation was successful, the Coolify dashboard should be available on port 8000.

Access the Coolify Dashboard 🌐

---

Open your browser and go to:

http://Your_IP_Address:8000

Replace Your_IP_Address with your server's public IP address.

Initial Setup (Admin Account) 👤

---

On your first visit, you will be asked to create your administrator account:

• Set a username
• Provide your email address
• Choose a strong password

Then log in to your Coolify dashboard.

Set Up a Custom Domain (Recommended for HTTPS) 🔒

---

Accessing Coolify through an IP address and port is suitable for initial setup. For regular use, configure a custom domain with HTTPS.

1. DNS Configuration: Add the following A records pointing to Your_IP_Address:

   • @ → Your_IP_Address
   • * → Your_IP_Address (optional, for deployed applications)

2. Coolify Configuration: In the Coolify dashboard, go to Settings and configure the Instance Domain, for example:

   coolify.yourdomain.com

Coolify can then configure the reverse proxy and SSL certificate for the instance.

After DNS propagation and SSL configuration are complete, access the dashboard using:

https://coolify.yourdomain.com

Back Up Coolify Installation Secrets 🔐

---

After installation, back up the Coolify environment file:

/data/coolify/source/.env

This file contains important installation secrets, including the APP_KEY, which is required when restoring a Coolify installation from backup.

WARNING: Keep the .env file secure and do not expose or share its contents.
