Istio customizable installation for Minikube

This repository tries to provide a customizable installation and configure an Istio mesh for DEVELOPMENT use. With this configuration you will be able to run Istio on a 4MB cluster

Check the values-minikube.yaml file to see the values overrided from the default Istio installation

Enabled services:

• Grafana
• Kiali
• Jaeger

How to use

• minikube start --memory 4096 If you have more memory I sugest increase the memory
• kubectl create ns istio-system
• kubectl apply -f 1-istio-init.yaml
• kubectl apply -f 2-istio-minikube-reduced.yaml
• kubectl apply -f 3-kiali-secret.yaml
• kubectl apply -f 4-label-default-namespace.yaml
• Wait until all pods are up and running, you can watch it with kubectl get po -n istio-system -w

Telemetry

Getting the url to access the systems

export MINIKUBE_IP=$(minikube ip)
echo $MINIKUBE_IP

Visit the address printed on the Browser

Cleanup

• Stopping the application samples/bookinfo/platform/kube/cleanup.sh

• Remove any kubectl port-forward processes that may be running killall kubectl

To generate the two yaml files with the last version of Istio

• Install helm https://helm.sh/docs/intro/install/
• Download and extract the Istio from https://github.com/istio/istio/releases/
• helm template ./install/kubernetes/helm/istio-init --name istio-init --namespace istio-system > istio-init.yaml
• helm template ./install/kubernetes/helm/istio --name istio --namespace istio-system --values values-minikube.yaml > 2-istio-main-minikube-reduced.yaml

That's all. Leave a star if it helped you!
