Official website of the Jenkins X project: Jenkins X. You can find here more information about the Jenkins X components. And I found this article about Prow to be quite good to get a better understanding about the different native Kubernetes CI/CD projects.
Create a new cluster using jx and minikube:

jx create cluster minikube --kubernetes-version=v1.15.4

Specify kubernetes version until this issue is fixed. Specify more resources to make sure the initial pipelines can succeed:

What is Jenkins X?

Not a simple answer to the question:

a CLI
a collection of community tools
a way of working

Requirements for going through all these steps:

A free GitHub organization with 2 free users (one will approve PRs and the other is a bot user used by the pipelines) OR just 2 free users (one will approve PRs and the other is a bot user used bythe pipelines)

What and Why is there Kubernetes?

Get started with Kubernetes in Docker (kind) in WSL2

The accompanying video for this tutorial is published on https://learn.alexchiri.com

Contents:

Recommendations
Install Docker CE for Linux
Configure Docker to start automatically in our WSL distribution when we log in to Windows
Install go

Create a multi-node kind cluster and with a different kubernetes version than default

The instructions in this tutorial are not WSL2 specific, but if you would like to see how to get started with kind in WSL2 (and afterwards follow along with this tutorial), do have a look at this video.

How to create a local multi-node Kubernetes cluster with kind

In order to create a multi-node cluster with kind, we need to create a configuration file. Let's say we want to create a 3 node cluster, 1 control-plane and 2 workers, we would then create the following configuration file (you can save it as kind-config.yaml):

kind: Cluster

	#!/bin/bash

	sudo apt-get update && sudo apt-get install -y jq curl unzip git python3 apt-transport-https ca-certificates software-properties-common jid ruby-full pkg-config

	export KUBECTL_VERSION="v1.15.10"
	export HELM_VERSION="v2.16.1"
	export EKSCTL_VERSION="0.11.1"
	export JX_VERSION="v2.0.1249"

	# install kubectl

	// This file was initially generated by Windows Terminal (Preview) 1.0.1402.0
	// It should still be usable in newer versions, but newer versions might have additional
	// settings, help text, or changes that you will not see unless you clear this file
	// and let us generate a new one for you.

	// To view the default settings, hold "alt" while clicking on the "Settings" button.
	// For documentation on these settings, see: https://aka.ms/terminal-documentation
