How to install Kubernetes (k8s) on Arch Linux

What is Kubernetes (K8s)?

Kubernetes (k8s) is an open-source system for automating the deployment, scaling, and management of containerized applications. It was originally developed by Google and is now maintained by the Cloud Native Computing Foundation (CNCF).

Kubernetes provides a platform-agnostic way to deploy and manage applications in containers, making it easier to build, test, and deploy applications in a consistent and reliable manner. It also provides features for scaling applications up or down, rolling out updates, and self-healing failures.

Kubernetes is widely used in the cloud and on-premises environments to deploy and manage applications in containers. It is compatible with a variety of container runtimes, such as Docker, rkt, and CRI-O.

Installation :

To install Kubernetes (k8s) on Arch Linux, you can follow these steps:

1. Install kubectl, the command-line tool for interacting with a Kubernetes cluster. You can do this by running the following command in your terminal:

    sudo pacman -S kubectl
   

2. Install kubeadm, the command-line tool for setting up a Kubernetes cluster. You can do this by running the following command in your terminal:

    sudo pacman -S kubeadm
   

3. Install a container runtime, such as Docker. You can do this by running the following command in your terminal:

    sudo pacman -S docker
   

4. Start and enable the Docker service:

    sudo systemctl start docker sudo systemctl enable docker
   

5. Initialize the cluster using kubeadm. For example, to set up a single-node cluster, you can run the following command:

    sudo kubeadm init
   

6. Set up the kubectl configuration. You can do this by running the following command:

    mkdir -p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config
   

7. Deploy a networking solution, such as Calico. You can do this by running the following command:

    kubectl apply -f https://docs.projectcalico.org/v3.16/manifests/calico.yaml
   

That's it! You should now have a working Kubernetes cluster on your Arch Linux system. You can check the status of the cluster by running the command kubectl get nodes.
