Easy Docker-Compose Installation On Ubuntu

This guide walks you through installing Docker on Ubuntu 24.04 (Noble Cloud) using a simple script. Docker is a powerful tool for containerizing applications, and this script automates the setup process for you.

---

What Does the Script Do?

The script:

• Updates your system’s package list.
• Installs prerequisites like curl and gnupg.
• Downloads Docker’s GPG key and sets up a secure keyring.
• Adds Docker’s official repository to your system.
• Installs Docker and its related tools.
• Verifies the installation by checking Docker and Docker Compose versions.

Prerequisites

Before you start, ensure:

• You have an Ubuntu 24.04 machine.
• You have sudo privileges.

Step-by-Step Guide

Step 1: Create the Script File

1. Open a terminal.
2. Create a new file named install_docker.sh:

   nano install_docker.sh
   

3. Paste the following script into the file: Github

    #!/bin/bash
    # Make the script executable: chmod +x install_docker.sh
    # Run the script: ./install_docker.sh
    # Update package lists and install prerequisites
    sudo apt-get update
    sudo apt-get install -y ca-certificates curl gnupg
   
    # Create the keyring directory
    sudo install -m 0755 -d /etc/apt/keyrings
   
    # Download and add Docker's GPG key
    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
    sudo chmod a+r /etc/apt/keyrings/docker.gpg
   
    # Add the Docker repository to apt sources
    echo \
    "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
    $(. /etc/os-release && echo $VERSION_CODENAME) stable" | \
    sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
   
    # Update package lists again
    sudo apt-get update
   
    # Install Docker and related components
    sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
   
    # Check Docker version
    docker -v
   
    # Check Docker Compose version
    docker compose version
   

4. Save the file (Ctrl + O, then Enter) and exit (Ctrl + X).

5. Start the script

    ./install_docker.sh
   

Congratulations!
