Installing Docker Desktop on KDE Neon

Welcome to Waggos, the idea behind this little blog is to keep a list of handy tutorials and in the process to improve my technical writing skills; I hope this blog can help someone out there in a rush because I know it will help me shortly.

Let’s begin with the first tutorial.

The recipe

Prerequisites:

Libvirt/KVM Virtualization
Docker’s GPG key
Docker deb repository

Enable Libvirt/KVM

Install libvirt and KVM packages

sudo apt install -y qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virt-manager

Add current user to libvirt and KVM groups

sudo usermod -aG libvirt $USER
sudo usermod -aG kvm $USER

For other users replace $USER in the commands above with the actual usernames

Docker’s GPG key

Create the directory keyrings inside /etc/apt

sudo mkdir -p /etc/apt/keyrings

Download the actual key:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

Docker DEB Repository

Create docker.list file using

sudo touch /etc/apt/sources.list.d/docker.list

Paste the following content inside the docker.list

deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu focal stable

Note.- focal is the code name of the distro I am using.

Refresh the packet list

sudo apt update

Optional: Install docker-ce and its dependencies

sudo apt install -y docker-ce-cli docker-scan-plugin pass qrencode tree uidmap xclip

Download and install docker-desktop

wget https://desktop.docker.com/linux/main/amd64/docker-desktop-4.13.0-amd64.deb

Note.- At the time of writing the current version of docker-desktop is 4.13-0

Install the downloaded deb file

sudo dpkg -i docker-desktop-4.13.0-amd64.deb

If you didn’t install docker-ce and company, install the missing dependencies using:

sudo apt -f install

If everything turns out right, when you open Docker Desktop, you will see the following window:

Deploying the very first container

Let’s run the most complex container in the world, the infamous hello-word:

docker run hello-world

And this is how I deployed my development environment using docker-desktop. See you next time.
