Installing Docker on Ubuntu 24.04 is a straightforward process that allows you to use container technology to develop, ship, and run applications. Docker is a popular tool among developers because it simplifies the process of managing application dependencies and ensures consistency across different environments. Whether you are a seasoned developer or a beginner, setting up Docker on your Ubuntu system can significantly enhance your workflow.

In this guide, we will walk you through the steps needed to install Docker on Ubuntu 24.04. We will start by updating your system, then install Docker, and finally, verify that Docker is working correctly on your machine.

Step 1: Update Your System

Before you install Docker, you need to update your system. Open your terminal and type:

sudo apt update
sudo apt upgrade

This will update your package lists and install any available upgrades.

Step 2: Install Docker on Ubuntu 24.04

To install Docker, add the Docker repository to your system. Run these commands in your terminal:

  1. Install required packages: 
    sudo apt install apt-transport-https ca-certificates curl software-properties-common
  2. Configure the GPG key: 
    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
  3. Set up the Docker PPA: 
    echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
  4. Update the package cache: 
    sudo apt update
  5. Install the Docker engine: 
    sudo apt install docker-ce container.io

Step 3: Start and Enable Docker

After installing Docker, start the Docker service and enable it to start on boot. Use these commands:

sudo systemctl start docker
sudo systemctl enable docker

Step 4: Verify Docker Installation

To check if Docker is installed correctly, run:

sudo docker --version

This command will display the installed Docker version.

Step 5: Add Current User to Docker Group

To run Docker commands without using sudo, add your current user to the Docker group. Execute the following command:

sudo usermod -aG docker $USER

Now, Apply the new group membership by logging out and back in, or by running:

newgroup docker

Step 6: Run Your First Docker Container

Now that Docker is installed, run a simple Docker container. Type the following command to run a test container:

docker run hello-world

This command downloads and runs a simple Docker container that prints “Hello from Docker!”
