In this guide, we shall see How to Install Docker CE on Ubuntu 24.04. A platform called Docker was created to simplify the process of developing, deploying, and operating applications that use containers. With containers, an application developer may bundle all the required components, like libraries and other dependencies, and send them as a single package. This guarantees that the program functions dependably when it is transferred between different computer environments.
Developers can concentrate on building code rather than wondering about the environment in which it will operate because Docker offers the tools and a platform to manage these containers effectively.
How to Install Docker CE on Ubuntu 24.04
Let’s get started!
Step 1. Update the System
Run the following command to update your system packages and reboot after an update.
sudo apt update && apt upgrade -y
sudo rebootStep 2. Install Required Dependencies
To enable Ubuntu 24.04 to connect to the Docker repositories over HTTPS, install the following packages:
sudo apt install apt-transport-https ca-certificates curl software-properties-commonAdd GPG Key
Use the following command to add the GPG Key for Docker on Ubuntu 24.04.
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -Add Docker Repository
Once you add the GPG Key, you must add the Docker Repository. Execute the following command.
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"Step 3. Install Docker On Ubuntu 24.04
You are now ready to install Docker by simply running the below command.
sudo apt-get install docker-ce docker-ce-cli containerd.io -yAdd your local user to the docker group after installing docker and its dependencies so that the local user can use it without using sudo to perform the docker command.
$ sudo usermod -aG docker $USER
$ newgrep docker
$ docker --versionNow start and enable docker services.
sudo systemctl enable docker
sudo systemctl start dockerVerify the docker status.
$ sudo systemctl status docker

Test Docker
We can now run the hello-world below to test the installation of Docker if it’s working fine.
$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
c1ec31eb5944: Pull complete
Digest: sha256:266b191e926f65542fa8daaec01a192c4d292bff79426f47300a046e1bc576fd
Status: Downloaded newer image for hello-world:latest
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/
For more examples and ideas, visit:
https://docs.docker.com/get-started/The above output shows that docker is working well.
Step 4. Using the Docker Command
- If you want to check the active containers simply run;
docker ps- You can add the -a flag to list all containers, even those that are not in use:
docker start <container-ID | container-name>- To stop running the container.
docker stop <container-ID | container-name>- To remove container use:
docker rm <container-ID | container-name>For more options run the help command.
$ docker --help
