Shell scripts for setup Kubernetes

Install Kubernetes with CRI-O runtime on CentOS 8 (./crio-centos8)

Prerequisites:

I recommend at least one host with minimum 2 cores, 4 GB RAM, 15 GB HDD
Installed CentOS 8 (I recommend "Server" profile)

Install:
Setup version of CRI-O and Kubernetes and run with sudo (or from root):

sudo bash -c "export REQUIRED_VERSION=1.18 && ./crio-centos8/k8s-crio-setup.sh"

Add user to Kubernetes cluster and generate KUBECONFIG (./k8s-add-user)

Prerequisites:

'jq' JSON processor installed
'kubectl' running with working 'KUBECONFIG'
