Automate Kubernetes and Istio Environment Setup

By Samir Behara on May 9, 2018 • ( 2 )

In this article, we will create an automated script to enable developers to work in Kubernetes and Istio environment. So basically once you run this script you will have a functional development environment set to get started with your development work.

This script is targeted towards developers using Mac and we will be using Homebrew – the package manager for macOS.

Homebrew is a free package manager for macOS and helps you to manage software in your Mac. You can install the software you need through command line in no time. There is no need to download DMG files and drag it to your applications folder. It makes the process of installing and uninstalling software so muck easier and faster.

Minikube is a tool which allows you to run a single-node Kubernetes cluster locally.

Kubectl is used for running commands to deploy and manage components against your Kubernetes instance.

The below script will install Homebrew, Minikube, Kubernetes Command Line Interface and Istio —

	# Check for Homebrew and install if we don't have it
	if test ! $(which brew); then
	echo "Installing homebrew…"
	ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
	fi

	# Make sure we are using the latest Homebrew.
	brew update

	# Check for Minikube and install if we don't have it
	echo "Installing Minikube to run a single-node Kubernetes Cluster locally…"
	brew cask install minikube
	echo "Minikube Installation Complete"

	# Check for Kubernetes Command Line Utility and install if we don't have it
	echo "Installing kubectl to manage components in your Kubernetes cluster…"
	brew install kubectl
	echo "kubectl Installation Complete"

	# Install Istio
	echo "Installation of Istio started…"
	curl -L https://git.io/getLatestIstio \| sh –
	cd istio-0.7.1/
	export PATH=$PWD/bin:$PATH
	kubectl apply -f install/kubernetes/istio.yaml
	echo "Istio Installation Complete"
