Kubernetes the hard way implementation

This is practical implementation of Kubernetes The Hard Way with bash scripts. The kubernetes version used is v1.21.0.

Prerequisites

Because the cluster will be provisioned on GCP, you need Google Cloud SDK installed on your machine and configured with your account:

gcloud auth login

And also make sure to set the project:

gcloud config set project <project-id>

Provision the cluster

All you need to do is to run the start script:

./start.sh

The proccess takes about 20 minutes to compelete and you will have a a working kubernetes cluster (3 controlplane nodes, 3 worker nodes) up and runnung.

Your kubeconfig will be configured to use the cluster and you can switch to the cluster context when you need:

kubectl config use-context kubernetes-the-hard-way

Test if the cluster is working:

kubectl get nodes

You should get the following output:

NAME       STATUS   ROLES    AGE   VERSION
worker-0   Ready    <none>   96s   v1.21.0
worker-1   Ready    <none>   64s   v1.21.0
worker-2   Ready    <none>   29s   v1.21.0

Destroy the cluster

When you are done you can destroy the cluster by running the destroy script:

./destroy.sh
