Prerequisites
To install Docker Desktop successfully, you must:
- Meet the general system requirements.
- Have an x86-64 system with Ubuntu 22.04, 24.04, or the latest non-LTS version.
- If you’re not using GNOME, you must install
gnome-terminalto enable terminal access from Docker Desktop:$ sudo apt install gnome-terminal
Install using the apt repository
Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker apt repository. Afterward, you can install and update Docker from the repository.
- Set up Docker’s
aptrepository.# Add Docker's official GPG key:sudo apt updatesudo apt install ca-certificates curlsudo install -m 0755 -d /etc/apt/keyringssudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.ascsudo chmod a+r /etc/apt/keyrings/docker.asc# Add the repository to Apt sources:sudo tee /etc/apt/sources.list.d/docker.sources <<EOF Types: deb URIs: https://download.docker.com/linux/ubuntu Suites: $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") Components: stable Signed-By: /etc/apt/keyrings/docker.asc EOFsudo apt update - Install the Docker packages.Latest Specific versionTo install the latest version, run:
$ sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
Note: The Docker service starts automatically after installation. To verify that Docker is running, use:$ sudo systemctl status docker
Some systems may have this behavior disabled and will require a manual start:$ sudo systemctl start docker - Verify that the installation is successful by running the
hello-worldimage:$ sudo docker run hello-world
This command downloads a test image and runs it in a container. When the container runs, it prints a confirmation message and exits.
