In the world of self-hosting, having an efficient setup is crucial for managing multiple applications, especially if you are working within the confines of a single Virtual Private Server (VPS). Coolify is an excellent choice for developers and homelab enthusiasts looking to simplify the deployment of their open-source applications while optimizing resource usage. This guide will show you exactly how to get started self-hosting everything with Coolify on a single VPS.

What is Coolify?

Coolify is an open-source self-hosting platform that streamlines the deployment of applications using Docker. It has an intuitive web interface that allows users to deploy, manage, and monitor applications with ease. By leveraging Docker, Coolify ensures that your applications run in isolated containers, providing a clean and manageable environment.

VPS Requirements

To successfully self-host with Coolify, you need a VPS that meets the minimum system requirements. Here’s a brief overview of the types of VPS offerings available, along with their prices:

For good performance while hosting multiple applications, it is advisable to choose at least 2 GB of RAM and sufficient disk space. The Hetzner Cloud VPS at 4.15 EUR/month and Contabo VPS at 5.99 EUR/month provide an excellent balance of cost and resources for Coolify.

Step 2: Connect to Your VPS

Once you’ve set up your VPS, connect to it using SSH. Replace your_user and your_ip with your actual username and server IP address:

ssh your_user@your_ip

Step 3: Install Docker

Coolify utilizes Docker containers, so the first step is to install Docker. Run the following commands:

sudo apt update
sudo apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt update
sudo apt install docker-ce

You can verify if Docker is correctly installed by checking the version:

docker --version

Step 4: Install Coolify

Now, we will install Coolify using Docker Compose. First, you need to install Docker Compose:

sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Next, create a directory for Coolify and navigate into it:

mkdir -p ~/coolify && cd ~/coolify

Create a docker-compose.yml file with the following contents:

version: '3.3'
services:
  app:
    image: coollabsio/coolify:latest
    container_name: coolify
    restart: unless-stopped
    ports:
      - "3000:3000"
    volumes:
      - coolify_data:/data
volumes:
  coolify_data:

Then, start the service:

docker-compose up -d
