Docker is a platform for building, running, debugging, and testing container applications. Nowadays, Docker has become a standard tool for software developers and system administrators. Docker is an innovative approach to running applications quickly without affecting the rest of the system. In this article, we are going to teach you How to Install and Access Docker Desktop on Ubuntu 22.04. You can check out the packages offered on the Eldernode website if you would like to purchase an Ubuntu VPS server.

Tutorial Install and Access Docker Desktop on Ubuntu 22.04
What is Docker Desktop?
Docker Desktop is a native open-source desktop application based on the Linux and Windows operating systems that creates a virtual environment. In this virtual environment, you can implement and run various applications. The first version of Docker was released in 2013. Docker is a tool that allows developers to easily develop applications in a sandbox called a container and run them on the host operating system that plays a key role in Docker. With the help of Docker, users can package an application with all its dependencies in a standardized software development unit.
Docker Desktop Features
1- Easy installation of a complete Docker development environment
2- Automatic Updates
3- Fast and reliable performance with native Windows Hyper-V virtualization
4- In-container development and debugging with supported IDEs
5- Ability to switch between Linux and Windows Server environments in Windows to build applications
6- Ability to work natively on Linux via WSL 2 on Windows machines
7- Ability to containerize and share any application on any cloud platform, in multiple languages and frameworks
8- Volume mounting for code and data
Prerequisites to Install Docker Desktop on Ubuntu 22.04
– Support for 64-bit kernel and CPU for virtualization
– KVM virtualization support
– systemd init system
– At least 4 GB of RAM
– Gnome or KDE desktop environment
– New version of QEMU
In the next section, we are going to teach you step by step how to Install Docker Engine on Ubuntu 22.04.
Installing Docker Engine on Ubuntu 22.04
First, you should remove the existing Docker repository using the following command:
sudo apt remove docker docker-engine docker.io 2>/dev/null
And update your system:
sudo apt update
sudo apt upgrade
Now you need to install the required packages by running the following command:
sudo apt -y install apt-transport-https ca-certificates curl software-properties-common
In this step, run the following command to add the Docker repository:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/docker-archive-keyring.gpg
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
Now you can install Docker on Ubuntu by entering the following command:
sudo apt install docker-ce docker-ce-cli containerd.io uidmap
Then add your user account to the docker group using the following command:
sudo usermod -aG docker $USER
How to Install Docker Desktop on Ubuntu 22.04
First, you should remove the existing Docker Desktop:
sudo apt remove docker-desktop
And clean up the system with the following commands:
rm -r $HOME/.docker/desktop
sudo rm /usr/local/bin/com.docker.cli
To remove the data files, run the following command:
sudo apt purge docker-desktop
You can download the latest Docker Desktop package with the following command:
If you using non-Gnome Desktop environments, install the Gnome-terminal package using the following command:
sudo apt install gnome-terminal
Now it’s time to install Docker Desktop:
sudo apt install ./docker-desktop-*-amd64.deb
Then accept the required dependencies installation to add a new entry in the /etc/hosts for Kubernetes:
.... 0 upgraded, 44 newly installed, 0 to remove and 0 not upgraded. Need to get 35.5 MB/439 MB of archives. After this operation, 129 MB of additional disk space will be used. Do you want to continue? [Y/n] y
A new entry will be added in the /etc/hosts as below:
cat /etc/hosts 127.0.0.1 localhost 127.0.1.1 ubuntu # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters # Added by Docker Desktop # To allow the same kube context to work on the host and the container: 127.0.0.1 kubernetes.docker.internal # End of section
How to Access Docker Desktop on Ubuntu 22.04
You can launch Docker Desktop from the application menu or through the terminal. Enter the following command to launch it through the terminal:
systemctl --user start docker-desktop
Now you should see the following page. Check the “I accept the terms” box and click Accept:
After the Docker Desktop starts, you will see the following home page:
Now you should check the versions using the following executables:
docker compose version
Images and containers of the Docker Desktop are stored in an isolated storage location in the VM. If running Docker Desktop and Docker Engine at the same time results in an error, you can stop the Docker Engine service using the following command:
sudo systemctl stop docker docker.socket containerd
And disable it with the following command:
sudo systemctl disable docker docker.socket containerd
If you want to see the available contexts:
docker context ls
You can use a preferred context by running the following command:
docker context use default
Enter the following command to use the docker-desktop context:
docker context use desktop-linux
How to Configure Docker Desktop on Ubuntu 22.04
Go to the Settings tab and choose the General option:
If you check the “Start Docker Desktop when you log in” box, you can enable Docker Desktop automatically start when you open your session. Also, you can do this using the following command:
systemctl --user enable docker-desktop
If you check the “Send usage statistics” box, reports will be sent to Docker Desktop.
You can see advice messages about the tool by checking the “Show weekly tips” box.
Check the “Open Docker Dashboard at startup” box to display the dashboard on startup.
If you want to enable docker-compose to use Docker Compose V2, check the “Enable Docker Compose V1/V2 compatibility mode” box.
Now choose the Resources option in the Settings tab:
In this section, you can limit the resources used by Docker. If you configure File Sharing in Advanced settings, you can share local directories with Linux containers. Click (+) to add a directory and (-) to remove it. Remember to click Apply & Restart after making any changes:
The Network section in the Resources tab is useful for network configurations. If the default choice of subnet interferes with something in your system, you can specify custom subnets here:
That’s it! Docker Desktop was successfully installed on Ubuntu 22.04.
Docker is a software platform that builds and develops Container-based applications. It shares the operating system kernel in isolation.
