Coolify is a powerful tool for managing applications using Docker containers. Here’s how to install Coolify and resolve Docker daemon connectivity issues on Ubuntu 24.04.

Prerequisites

• Ubuntu 24.04 LTS installed with root access or sudo privileges.
• Internet connectivity to download packages.

Step 1: Install Coolify

1. Download and Run Installer Script: Open a terminal and execute the following command to download and run the Coolify installer script:

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

This script will handle the installation of Coolify and its dependencies.

Step 2: Fix Docker Connectivity Issue

If you encounter the error "Cannot connect to the Docker daemon at unix:///var/run/docker.sock", follow these steps to resolve it:

1. Check Docker Daemon Status: Verify if Docker is running by executing:

   sudo systemctl status docker

If Docker is not active, start it with:

   sudo systemctl start docker

1. Enable Docker Service: Ensure Docker starts automatically on boot:

   sudo systemctl enable docker

1. Verify Docker Installation: Confirm Docker is installed and accessible:

   docker --version

1. Add User to Docker Group (Optional): If needed, add your user to the docker group to run Docker commands without sudo:

   sudo usermod -aG docker $USER

Log out and log back in for group changes to take effect.

1. Restart Docker Service: Restart Docker to apply any changes made:

   sudo systemctl restart docker

Step 3: Verify Coolify Installation

Once Docker connectivity is fixed, verify Coolify installation by accessing its command-line interface or web interface as per the installation instructions.

Conclusion
