Learn how to install Docker on Ubuntu 24.04 with this step-by-step guide. Follow the instructions to set up Docker quickly and efficiently, ensuring your applications run consistently across different environments. Perfect for developers, system administrators, and DevOps engineers.
If you’re looking to install Docker on Ubuntu 24.04, you’ve come to the right place. Docker is an essential tool for developers, system administrators, and DevOps engineers. It simplifies the process of managing application containers, enabling you to develop, ship, and run applications consistently across different environments. This guide will walk you through the steps to install Docker on Ubuntu 24.04.
Before diving into the installation process, let’s briefly explore why Docker is so popular:
Consistency: Docker ensures that your application runs the same way, regardless of where it is deployed. Isolation: Each Docker container runs in its isolated environment, which helps prevent conflicts between different applications. Portability: Containers can be easily moved from one server to another. Efficiency: Docker uses fewer resources than traditional virtual machines. |
With these benefits in mind, let’s get started with the installation process.
Before you install Docker, ensure your system meets the following prerequisites:
sudo privilegesInstall Docker on Ubuntu 24.04: Step-by-Step Instructions |
First, update your system’s package index to ensure you have access to the latest updates and security patches.
sudo apt update -y && sudo apt upgrade -y
Next, install the necessary packages to allow apt to use repositories over HTTPS.
sudo apt install apt-transport-https ca-certificates curl software-properties-common -y
To ensure the authenticity of the Docker packages, add Docker’s official GPG key:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
Add the Docker repository to apt sources:
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
Now, update the package database with the Docker packages from the newly added repository:
sudo apt update
Then, install Docker:
sudo apt install docker-ce docker-ce-cli containerd.io -y

After the installation is complete, verify that Docker is installed and running:
sudo systemctl status docker

You should see output indicating that Docker is active and running. Additionally, you can check the Docker version:
docker --version
Docker version 26.1.4, build 5650f9b
By default, Docker commands must be run as the root user or with sudo. To avoid typing sudo before every Docker command, add your user to the docker group:
sudo usermod -aG docker $USER
After running this command, log out and log back in to apply the changes. NOTE: When Docker is installed on Ubuntu 24.04, it is set to start automatically upon reboot. However, it is advisable to verify this configuration and restart your machine to ensure everything is working correctly.
sudo systemctl reboot
When your machine is back online, repeat Step #6 to verify docker is operational.
To confirm that Docker is installed correctly, run the hello-world image:
docker run hello-world
...omitted for brevity...
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:
https://hub.docker.com/

https://docs.docker.com/get-started/
If everything is set up correctly, you should see a message indicating that Docker is working.
If you encounter any issues during the installation, consider the following troubleshooting tips:
1. Check Service Status: Ensure the Docker service is active using sudo systemctl status docker. |
sudo systemctl status docker
| 2. Reinstall Docker: If problems persist, you can remove Docker: |
sudo apt remove docker-ce docker-ce-cli containerd.io
| Along with any associated docker directories: |
sudo rm -rvf /var/lib/docker && sudo rm -rvf /var/lib/containerd
| Then, reinstall docker: |
sudo apt install docker-ce docker-ce-cli containerd.io
3. Review Logs: Check Docker logs for any errors using sudo journalctl -u docker. |
sudo journalctl -u docker
