Kubernetes is an open-source container orchestration system for automating deployment, scaling, and management of containerized applications. Kubernetes is available for Linux, and in this tutorial, we will learn how to install Kubernetes on MXLinux Latest.
Before proceeding with the installation of Kubernetes, you will need:
Before starting the installation, make sure your system's packages are up to date. Run the following command to update your system packages:
sudo apt update && sudo apt upgrade
Kubernetes needs a container runtime to operate, and Docker is the preferred container runtime for Kubernetes. We will install the latest version of Docker Community Edition using the default Debian Buster repository.
Run the following commands to install Docker:
sudo apt install apt-transport-https curl gnupg2 software-properties-common
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io
After installing, start Docker and enable it to start automatically at boot time:
sudo systemctl start docker
sudo systemctl enable docker
To verify that Docker is installed correctly, run the following command:
sudo docker run hello-world
If successful, you should see a "Hello from Docker!" message.
In this step, we will install Kubernetes on our MXLinux system. We will use kubeadm to install Kubernetes on our system. kubeadm is a tool for bootstrapping a Kubernetes cluster.
Run the following commands to install kubeadm:
sudo curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo apt update
sudo apt install -y kubelet kubeadm kubectl
After installation, start the kubelet service:
sudo systemctl enable kubelet
sudo systemctl start kubelet
Now that we have installed Kubernetes, let's create a new Kubernetes cluster by running the following command:
sudo kubeadm init
This will start the creation of a new Kubernetes cluster with a single control plane node. Wait for the command to finish executing.
After the cluster creation, to use the kubectl command-line tool to interact with the Kubernetes API server, run the command below:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
To view the cluster nodes, run the command below:
kubectl get nodes
If successful, you should see a list of nodes in your Kubernetes cluster.
In this tutorial, we have successfully installed Kubernetes on MXLinux Latest. You can now start deploying containerized applications on your Kubernetes cluster.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
