In this tutorial, we are going to learn how to install Docker on Ubuntu 24.04. Docker is a platform that enables developers and system administrators to build, run, and share applications in containers.

Installing Docker on Ubuntu 24.04
There exits two editions of docker available. Docker CE and Docker EE.
- Docker (Community Edition) is the open-source, community supported version of Docker and is available for free.
- Docker EE (Enterprise Edition) is a commercial/premium version of Docker and is support by Docker Inc.
There are different methods in which you can install Docker;
- Installing Docker from Docker Repositories
- Installing Docker manually using the DEB binary package
- Installing Docker using Docker Installation Script (Beyond the scope of this tutorial).
Installing Docker on Ubuntu 24.04 from Docker Repositories
Install Docker repository GPG signing key.
To install Docker from Docker, you first need to install some required packages by executing the command below. Some of the package may already be installed though;
sudo apt updatesudo apt install apt-transport-https \
ca-certificates \
curl \
gnupg-agent \
software-properties-common
Next, install Docker repository GPG signing key.
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | \ sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/docker.gpg
Install Docker Repository on Ubuntu 24.04
Run the command below to install Docker repository on Ubuntu 24.04.
echo "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -sc) stable" > /etc/apt/sources.list.d/docker-ce.list
Update System Package Cache
After that, update package cache.
sudo apt update
Install Docker from Docker Repository
Install Docker and other tools including containerd.io, An open and reliable container runtime.
sudo apt install docker-ce docker-ce-cli containerd.io
Note that, even if you install just docker-ce package, other tools like docker-ce-cli and containerd.io will be installed along with it.
sudo apt install docker-ce

Installing Docker using DEB Binary Package
If you want to go the manual way, you can simply download Docker DEB binary package for your specific system version from https://download.docker.com/linux/ubuntu/dists/.
For example, in this case to download the DEB binary packages for Ubuntu 24.04 Noble Numbat, navigate to https://download.docker.com/linux/ubuntu/dists/noble/pool/stable/amd64/ and grab the .deb files.
To download docker-ce, docker-ce-cli and containerd.io, you would simply pull them as follows;
wget https://download.docker.com/linux/ubuntu/dists/noble/pool/stable/amd64/docker-ce_26.1.1-1~ubuntu.24.04~noble_amd64.deb
wget https://download.docker.com/linux/ubuntu/dists/noble/pool/stable/amd64/docker-ce-cli_26.1.1-1~ubuntu.24.04~noble_amd64.deb
wget https://download.docker.com/linux/ubuntu/dists/noble/pool/stable/amd64/containerd.io_1.6.31-1_amd64.deb
You can then install them using the apt or dpkg package manager. Be sure to install docker-ce-cli and containerd.io before docker-ce.
sudo apt install ./docker-ce-cli_26.1.1-1~ubuntu.24.04~noble_amd64.deb
sudo apt install ./containerd.io_1.6.31-1_amd64.deb
sudo apt install ./docker-ce_26.1.1-1~ubuntu.24.04~noble_amd64.deb
Checking Installed Docker Version
To check the version of installed Docker, simply run the command;
docker --version
Docker version 25.0.3, build 4debf41
Starting Docker Service
To start and enable Docker and Containerd service to run on system boot;
sudo systemctl enable --now docker containerd
Running Docker as a non-root user
If you run Docker as standard system user, you may get such an error;
docker run hello-world
docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: ... /var/run/docker.sock: connect: permission denied. See 'docker run --help'.
Therefore, if you need to run docker as non-root user, simply add the user you want to run docker as to docker group or simply, grant the user sudo rights. For example to add current user to docker group;
sudo usermod -aG docker $USER
Once you have added the user to the Docker group, log out and login again to have the user group membership re-evaluated.
You can then run docker as the standard user.
Verifying Docker installation
To verify that Docker is running well, you can try running the hello-world container image.
docker run hello-world
NOTE: If you still get the same permission denied error after adding user to docker group, logout and login again and you should be able to run docker as a standard user.
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
c1ec31eb5944: Pull complete
Digest: sha256:4bd78111b6914a99dbc560e6a20eab57ff6655aea4a80c50b0c5491968cbc2e6
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://docs.docker.com/get-started/
To list running containers;
docker ps -a
