Setting up Minikube and Istio service mesh on your computer

Minikube is a tool that makes it easy to run Kubernetes locally. Here is the list of resources that will help you to set up Minikube on your machine along with Istio and other tools.

To Install:

1. Install Minikube :
•  https://kubernetes.io/docs/tasks/tools/install-minikube/
2. Install Istio: 
• https://istio.io/docs/setup/kubernetes/prepare/platform-setup/minikube/
• https://istio.io/docs/setup/kubernetes/install/helm/

Here is the quick summary of all commands for installing Minikube and Istio on macOS

Install Minikube
============

$ brew cask install minikube
$ minikube start --memory=16384 --cpus=4 --kubernetes-version=v1.14.2


Install Istio
========

$ curl -L https://git.io/getLatestIstio | ISTIO_VERSION=1.2.4 sh -
$ cd istio-1.2.4
$ export PATH=$PWD/bin:$PATH
$ for i in install/kubernetes/helm/istio-init/files/crd*yaml; do kubectl apply -f $i; done
$ kubectl apply -f install/kubernetes/istio-demo.yaml
$ get svc -n istio-system
$ kubectl get svc -n istio-system
$ get pods -n istio-system


Install Istio bookinfo demo app
===============================

$ kubectl label namespace default istio-injection=enabled
$ kubectl apply -f samples/bookinfo/platform/kube/bookinfo.yaml
$ kubectl get services
$ kubectl get pods
$ kubectl exec -it $(kubectl get pod -l app=ratings -o jsonpath='{.items[0].metadata.name}') -c ratings -- curl productpage:9080/productpage | grep -o ""
$ kubectl apply -f samples/bookinfo/networking/bookinfo-gateway.yaml
$ kubectl get gateway
$ export INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="http2")].nodePort}')
$ export SECURE_INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="https")].nodePort}')
$ export INGRESS_HOST=$(minikube ip)
$ export GATEWAY_URL=$INGRESS_HOST:$INGRESS_PORT
$ printenv GATEWAY_URL


Try bookinfo demo app
=================

Open browser: http://192.168.99.113:31380/productpage (Please note that hostname:port used in the URL '192.168.99.113:31380' is derived from the output of  $printenv GATEWAY_URL )

The above resources will help you to set up the Minikube on your machine. I often run into issues with minikube instance that runs on on my macOS and then look around for  options to delete the faulty instance. Finally, I decided to note it down somewhere for quick access ;)

To Unistall Minikube:

$ minikube delete

$ brew cask uninstall minikube

$ rm -rf /usr/local/bin/minikube

$ rm -rf ~/.minikube .kube
