How to Install Docker on Ubuntu 24.04

In this tutorial you will learn how to install Docker on Ubuntu 24.04, from system update to running your first container.

Step 1: Update the system

Before installing Docker, update the package list and upgrade existing packages.

sudo apt update
sudo apt upgrade

Step 2: Install Docker

Add Docker's repository and install required packages.

Install prerequisite packages: sudo apt install apt-transport-https ca-certificates curl software-properties-common

Import Docker’s 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 APT repository: 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

Refresh the package index: sudo apt update

Install Docker Engine: sudo apt install docker-ce container.io

Step 3: Start and enable Docker

Start the Docker service and configure it to start on boot.

sudo systemctl start docker
sudo systemctl enable docker

Step 4: Verify the installation

Check that Docker is installed correctly.

sudo docker --version

Step 5: Add your user to the Docker group

Allow running Docker commands without sudo.

sudo usermod -aG docker $USER

Apply the new group membership:

newgroup docker

Step 6: Run your first Docker container

Test the installation with a simple container.

docker run hello-world

Common Docker commands

List images: sudo docker images

List running containers: sudo docker ps

List all containers: sudo docker ps -a

Stop a container: sudo docker stop CONTAINER_ID

Remove a container: sudo docker rm CONTAINER_ID

Remove an image: sudo docker rmi IMAGE_ID

Conclusion

Congratulations! You have successfully installed Docker on Ubuntu 24.04 and run your first container. Docker simplifies application deployment and management; continue exploring its commands and ecosystem to become proficient.
