How to Install Kubernetes on Alpine Linux Latest

Kubernetes is an open-source container orchestration tool that helps manage containerized applications. In this tutorial, we will walk through the steps to install Kubernetes on Alpine Linux Latest.

Prerequisites

Before installing Kubernetes, ensure that you have the following prerequisites:

• A running instance of Alpine Linux Latest
• Root access to the instance or a user account with sudo privileges
• A basic understanding of command-line interface (CLI)

Step 1: Update the system

The first step is to update the system to ensure that all packages are up-to-date.

sudo apk update && sudo apk upgrade

Step 2: Install curl

Kubernetes requires curl to be installed, so we will install curl using the following command.

sudo apk add curl

Step 3: Install kubectl

To install kubectl, run 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 kubectl binary executable using the following command.

sudo chmod +x kubectl

Move the downloaded kubectl binary into PATH using the following command.

sudo mv kubectl /usr/local/bin/

sudo kubeadm init

Wait for the initialization to complete. Once done, copy the kubectl configuration file to your home directory.

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

Step 6: Run Kubernetes

Run the following command to run Kubernetes.

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