Kubernetes is an open-source platform for automating deployment, scaling, and management of containerized applications. In this tutorial, we'll walk through how to install Kubernetes on Clear Linux Latest using the official Kubernetes installer.
Before we start installing Kubernetes on Clear Linux Latest, you need to meet the following prerequisites:
Before installing Kubernetes, you need to install Docker on Clear Linux Latest. The easiest way to install Docker is by using the following command:
sudo swupd bundle-add containers-basic
This command installs the basic container runtime and tools, including Docker. After the installation completes, check the Docker version by running the following command:
docker -v
If Docker is installed correctly, you should see the installed version of Docker.
After installing Docker, it's time to install Kubernetes. Kubernetes is not available in the Clear Linux Latest official repository, so we need to use the Kubernetes installer to install it. Before we start, make sure you have curl installed on your machine. You can install it by running the following command:
sudo swupd bundle-add curl
Once curl is installed, download the Kubernetes installer script by running the following command:
curl -LO "https://dl.k8s.io/release/$(curl -L -s "https://dl.k8s.io/release/stable.txt")/bin/linux/amd64/kubectl"
Make the downloaded binary executable by running the following command:
sudo chmod +x kubectl
Move the binary to a directory in your PATH so that it's executable from anywhere. To do that, run the following command:
sudo mv kubectl /usr/local/bin/
After installing kubectl, it's time to install kubeadm and other Kubernetes components. Run the following commands to install them:
sudo curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
sudo touch /etc/apt/sources.list.d/kubernetes.list
echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo swupd update
sudo swupd bundle-add kubernetes
After installing Kubernetes, check the Kubernetes version by running the following command:
kubectl version
The output should show the client and server versions of Kubernetes.
Finally, start the Kubernetes services by running the following command:
sudo systemctl start kubelet
sudo systemctl enable kubelet
The kubelet service is responsible for running the containers on each node.
In this tutorial, we have shown you how to install Kubernetes on Clear Linux Latest. Now you are ready to deploy and manage containerized applications on your Kubernetes cluster. Happy containerizing!
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!
